A neglected bag of mulch is a great place to raise a colony of termites.

A couple of weeks ago I went to the back yard to dispose of an unused bag of mulch near my woodshed. Upon lifting the bag, I discovered my tardiness created the perfect home for a colony of eastern subterranean termites. These ubiquitous rascals set up shop beneath the mulch bag, dining on chips of wood leftover from my wood-splitting efforts. They also dined on delectable morsels of cellulose and lignan in the mulch within the plastic bag. In addition to large-headed, large-jawed soldiers and diminutive workers, dozens of winged reproductives were ready to take flight on their mission to found new colonies. Termites are regular visitors to my landscape. Several years ago, on a sunny spring morning with the air temperature hovering in the 70s, I was treated to a full-blown termite swarm. The wooden risers of ancient garden steps were home to a massive termite colony. Over several hours, thousands of adult reproductive termites issued forth and took wing, fluttering off to establish colonies of their own.

Here’s a recipe for making termites. Buy one bag of mulch in autumn and place it on the ground near the woodshed where there are lots of wood chips. Let it rest undisturbed for six or seven months. When temperatures climb into the 70’s in April, turn it over and enjoy plenty of workers and dozens of winged reproductives ready to fly off and establish new colonies. Why, you can even find them inside the bag of mulch.

Termites are remarkable creatures with the ability to perform a digestive magic trick unparalleled in the human world. They consume wood. To utilize nutrients tied up in a biopolymer hard enough to dull an axe blade, most termites rely on symbiotic bacteria in their gut to digest the rugged plant material called cellulose. Some primitive species of termites enlist unicellular organisms called protozoa to accomplish this feat. Termites have an unusual and rather crude way of passing these vital microbes from one termite to the next. They employ a process known as proctodeal trophallaxis. One termite excretes a droplet of microbe-packed fluid from its anus. This packet of goodies is consumed by another termite waiting at the rear end. Yum! In addition to the transfer of vital symbionts from one termite to the next, trophallaxis is also a way of disseminating chemical messages called pheromones that regulate the development and behavior of termites within the colony.

Eastern subterranean termite soldiers have enlarged heads with powerful jaws. A tiny newly molted worker nymph is overshadowed by the huge soldier.

Termites are part of an elite group of social insects that include ants, bumble bees, honey bees, and yellowjackets we met in previous episodes of Bug of the Week. Social insects such as termites have a distinct division of labor with a caste system that includes specialized workers, soldiers, and reproductives. Workers are the most common caste in the subterranean termite colony. The primary tasks of these cream-colored laborers are to consume and process wood, seek new resources, construct galleries, build foraging tubes, and care for the young and reproductives. As the name implies, soldiers are tasked with colony defense. They are easily recognized by their enlarged heads with powerful darkened jaws. Depending on the species, soldiers are armed with jaws that stab, cut, or snap and whack an enemy. Termite reproductives are called kings and queens. As light-colored juveniles in the colony, they pass through a developmental stage called the nymph and are distinguished from workers by developing wing buds found on the thorax just behind the head. When they molt to the adult stage to become males (kings) and females (queens), their cuticle tans to dark black. This tanning process allows them to retain body moisture as they exit the damp earth and enter the drier world above ground.

Who’s filling the air around my home on a sunny spring morning? Why, thousands of reproductive termites spawned from wooden steps in my backyard. Watch as they issue forth from gaps in the wood and mount vegetation to take flight. Can you count how many there are?

During spring and summer in the DMV, the air can be filled with thousands of termites, known as primary reproductives, swarming to found new colonies. But the world above ground is treacherous and only a few of the thousands that emerge live to establish a new colony. After landing at a new site, wings are no longer needed, and kings and queens will quickly shed their wings by snapping them off with quick twists and turns of their body. Hopeful males frantically pursue potential mates and the lucky ones that succeed in the mating game help their queen establish a colony. Queens of some species may live more than 40 years and produce more than 20,000 eggs per day. Eggs hatch and develop into workers, soldiers, and new reproductives. In addition to primary reproductives, termite colonies may also contain light colored secondary reproductives lacking wings that develop directly from nymphs, and tertiary reproductives that develop directly from workers. This remarkable system of reproductive redundancy undoubtedly contributes to the longevity and success of a termite colony.

After taking flight and landing at a new colony site, a female termite snaps-off her wings and is quickly pursued by a hopeful suitor.

In the natural world, termites live in subterranean nests, foraging on fallen trees. But with the advent of domestic structures, they often colonize dark interiors of floor joists and paneling within our home if conditions of moisture and temperatures suffice. They reach the structural wood of our buildings by constructing tunnels of soil, wood, saliva, and excrement from an outdoor colony like the one in my flower bed, up foundation walls until they reach the wood of a sill plate or floor joist. There they enter the home. If wood is sufficiently moist, let’s say it is due to a leaky pipe, plugged gutter, or cracked foundation, termites can set up shop inside your home. The appearance of swarming winged primary reproductives inside your home is a sure-fire indication of an infestation.

Parasitoids at the porch light: Ichneumon wasps, Ophioninae

 

On warm nights in late winter and early spring, Ophioninae wasps are regular visitors to my porch light.

 

The return of some delightful 70-degree weather last week heralded the return of lovely parasitoid wasps in the subfamily of Hymenoptera known as the Ophioninae. Each year we welcome these nocturnal visitors to my porch light as one of the harbingers of spring. They regularly appear on the first 60-ish degree evenings in March at my porch light. This year I discovered my first one last week on a windowsill near my houseplants. The mystery of how it got into the house remains unresolved, but we were still delighted to greet it.

Beneath the glow of my porch light, an Ophioninae wasp grooms its antenna and then taps its front foot in time with the music.

A beautiful ichneumonid wasp rests on the chrysalis of a swallowtail butterfly from which it emerged.

Ophioninae wasps belong to a large and important family of membrane-winged insects known as ichneumon wasps. Ichneumon wasps perform the important ecosystem service of biological control by parasitizing some of our most important pests, including corn earworms and white grubs. However, they also attack other non-pestiferous insects including the larvae of butterflies. Some years ago, we collected a beautiful caterpillar, the larva of the tiger swallowtail butterfly. After eating leaves like a ravenous teenager, it formed a remarkable chrysalis resembling a dead leaf. We placed the chrysalis in a terrarium and anxiously awaited the appearance of a beautiful swallowtail butterfly. Events took an unexpected turn when a feisty looking wasp emerged from the chrysalis instead of a gorgeous butterfly. You see, unbeknownst to us, prior to the capture of the swallowtail larva, a parasitoid ichneumon wasp had visited it. The female ichneumon wasp likely grappled with the caterpillar before stinging it and depositing an egg within.

The fascinating part of this story is that the parasitoid inside the swallowtail did not immediately develop and emerge from the caterpillar. This clever parasitoid waited for the caterpillar to feed and grow before beginning its own development. The tiny invader then completed its development and emerged as an elegant ichneumon wasp. Parasitoids with this type of delayed development within a host are called koinobionts. Many species of koinobionts synchronize development with that of their host by responding to changing levels of hormones produced by their host during growth and development.

Ichneumonid wasps can be a little testy when sharing a droplet of honey.

The humongous ovipositor on this ichneumon wasp in the genus Megarhyssa is used to drill beneath the bark of tree to deposit an egg inside a larva developing deep within the wood.

Returning now to the present, if you would like to see ichneumonid parasitoids, switch on your porchlight on a warm spring evening, and see who arrives. Don’t be surprised if several pale orange Ophioninae ichneumons appear. If you dare, do as we do and invite them in for a drink. As you see in the video, a little honey and water seemed just the right tonic for these busy parasitoids. After they had their fill, we bid them adieu and returned them to the wild. Perhaps my hospitality will be rewarded in a few weeks by these ichneumons in the form of koinobionic attacks on the pesky caterpillars and white grubs that perennially plague my flower beds.

Come one, come all to explore the Insect Petting Zoo: Maryland Day, Saturday April 26, 2025

 

Children of all ages will have a great time at the Maryland Day Insect Petting Zoo.

 

The lovely lubber sports multiple defense techniques.

One of the joys of spring is observing the antics of insects and their relatives as they resume their activities outdoors. To celebrate this annual renaissance, the Department of Entomology hosts an award-winning Insect Petting Zoo as part of the Maryland Day Gala at the College Park Campus of the University of Maryland on Saturday, April 26, from 10 am to 3 pm. The Insect Petting Zoo is in the Plant Sciences Building on the ground floor directly across from Regents Drive parking garage.

Come to the Insect Petting Zoo, Saturday April 26 at the University of Maryland, College Park. Travel around the world to meet rocking Vietnamese walking sticks and giant Australian walking sticks pretending to be dead leaves. Amazing Malaysian leaf insects will try to fool you and watch out for the whip scorpion and its smelly surprise. Hold a giant tarantula if you dare, and look at, but don’t touch, the black widow spider. Meet the deadliest creature on our planet, blood-thirsty mosquitoes, and pet a friendly, furry Eastern tent caterpillar. Fast moving green tiger beetles will prowl their cage while blue death feigning beetles will be stuck in second gear. Learn why carpenter bees make holes in your deck and why iconic honeybees and their kin are imperiled in our rapidly changing world. Hope to see you at Maryland Day.

Is that a leaf or a leaf insect? Come to the Insect Petting Zoo at Maryland Day to find out.

This year’s petting zoo will feature an incomparable ensemble of friendly, ferocious, and creepy crawly creatures. A visit to the petting zoo is sure to delight insect aficionados of all ages. This year’s extravaganza features bugs from around your home and around the world. Giant Lubber locusts straight from the Everglades of Florida will reveal their favorite delicacies and how they defend themselves from being eaten. Vietnamese and Australian walking sticks are true masters of disguise and giant Madagascar hissing cockroaches will blow your mind with their size and agility. Watch out for the Whip Scorpion that has a clever trick up its sleeve, or should we say its tail, to thwart attacks by enemies. If you are lucky, you might catch a glimpse of a Black widow spider with a bright red hourglass tattooed on her abdomen, a ferocious Green Tiger beetle hungry for fresh meat, or a Carpenter bee buzzing about its cage. The arts of trickery, mimicry, thanatosis, and other feats of deception and disguise will be revealed by Blue Death Feigning beetles, the European sowbug (roly – poly), darkling beetles (armored stink beetle), the remarkable, petite orchid mantis, and strange leaf insects.

The Spotted Lanternfly is a beautiful insect, but a dastardly plant pest and nuisance in your landscape.

The Insect Zoo is not just a treat for the eyes. Children of all ages will have the chance to hold and touch (with parental permission of course) a multi-legged millipede from the desert or a hairy Eastern tent caterpillar from a cherry tree. The very brave may even have a chance to hold a giant tarantula. If touching isn’t your thing, then you can listen to the buzzing of a bee or the hissing of a cockroach from Madagascar. Meet face to face the number one killer of humans on the planet – dreaded bloodthirsty mosquitoes. Curious smells are on the menu as well. Learn what unwelcome house guests have the aroma of cilantro and discover an arachnid with the pungent odor of vinegar. If you are feeling sociable, investigate the wonders of perhaps our most important social insect, the honeybee. Stop by the invasive species corner and meet dastardly Emerald Ash Borers, the nefarious home invader Brown Marmorated Stink Bug, and the newcomer in our region, Spotted Lanternfly.

 

Children can collect insect stickers and the first 600 visitors may take home a Terrapin Lady Beetle to release in their garden to put a beat-down on insect pests lurking there. 

Don’t miss The Swamp – If you enjoy the life aquatic, be sure to stop by The Swamp across the hall and learn how dragonflies capture their prey and how diving beetles extract oxygen from water.

So, come one, come all to explore Maryland Day and the Insect Petting Zoo!

What is that bee and why is it divebombing me? Male eastern carpenter bees, Xylocopa virginica

 

Next time you are dodging carpenter bees, take a moment to check out their head. I’ll bet you will find a white patch on its face between its eyes, the hallmark of the male carpenter bee.

 

A week or so ago, during a Q and A session at a meeting, I was asked by one nature enthusiast why large black bees were bombarding him in his back yard. Without fail, about this time each spring humans who venture too near a child’s wooden play set, wooden benches or railings, mailbox posts, decks, or houses with cedar siding are divebombed by territorial male bees. The bees have nothing against humans. They are simply jealously guarding potential wooden nest sites from interlopers. Interlopers include other male carpenter bees or almost any other creature that comes into range, including humans.  

Wooden structures like this play set bear telltale damage as woodpeckers search for carpenter bees inside the wood. Male carpenter bees zoom around nearby sensing that nubile female bees will soon emerge from these galleries. They divebomb other competing males and nosy humans, aggressively defending their mating territory. When females emerge, they will quickly be mated by diligent guy bees patrolling nearby. Once inseminated, females build new galleries in wooden structures creating nesting sites for their young.

On the outside of a piece of wood all you see of the carpenter bee’s handiwork is a perfectly round hole.

Why do they do this? Here’s the deal. Female carpenter bees build galleries in wooden structures to serve as nurseries for their young. Male carpenter bees go to great lengths to convince potential mates of their worthiness by selecting and defending prime nesting sites. When other male carpenter bees approach defended territories, remarkable aerial battles ensue. Swooping, grappling, and biting often result in both combatants tumbling to earth before one withdraws from the fray. I watched one victorious male guard a nesting site and soon a lovely and somewhat coquettish lady carpenter bee arrived. She rested on the wooden bench guarded by her suitor and a short but energetic romantic interlude ensued. As far as I could tell, the male flew off somewhere, perhaps for more battles or romantic conquests, but the female bee had different matters to attend. After mating, the she bee begins the task of excavating a hole in the wooden structure to be used as a nursery for her brood. Her powerful mandibles create a slightly oval to almost perfectly round hole as she penetrates the wood to the depth of about a half inch. She then makes a right angle turn and continues tunneling parallel to the grain of the wood excavating a series of brood-cells in a linear tunnel. In a piece of wood removed from one of the benches, I observed several tunnels more than a foot in length, some of which branched into secondary galleries. Each tunnel contained as many as thirteen individual brood-cells.

But on the inside, you can see a gallery of brood chambers carved into the wood by the mother bee for her babies.

To construct each multichambered gallery represents more than a month’s worth of chewing and one has to admire the determination of these industrious gals in excavating a home for their young. After the chambers are built, they are meticulously cleaned and filled with bee bread, a nutritious mixture of pollen, nectar, and secretions from glands on the female’s body. Bee bread serves as the food for the young carpenter bees. Starting at the end farthest from the entrance the female deposits an egg in each brood-cell. Each egg hatches into a legless larva that eats bee bread and develops during the course of spring and summer. In brood-cells furthest from the entrance, older larvae complete development first, pupate, and then after emerging from the pupal case in late summer these new adults push their way past brothers and sisters to escape the gallery and search for nectar and pollen. As summer wanes and autumn waxes, newly minted bees forage during the day and return to their galleries to spend the night. With the end of blossoms in the fall, carpenter bees return to their snug tunnels to chill out until the following spring, protected from the ravages of winter.

On a chilly dewy morning in spring don’t be surprised to see a male carpenter bee (left) and a female carpenter bee (right) resting on a flower head.

In locations where carpenters are present, watching humans duck and cover is almost as entertaining as watching aerial battles among male bees. Male bees lack stingers and although the gals are equipped to sting, I have never been stung by one nor have I heard of anyone who was harmed by these fascinating creatures. Carpenter bees do cause some damage to wooden structures. And once woodpeckers find a structure housing carpenter bees, they get busy and can do some remarkable destruction as they peck holes in the wood searching for carpenter bee babies for dinner. Nonetheless, these entertaining native bees provide important services by pollinating our trees, shrubs, and crops.

At past events such as Maryland Day at the University of Maryland at College Park, which will be held on Saturday, April 26 this year, a thousand or more people visit our Insect Petting Zoo. At the zoo our resident carpenter bees receive much interest and attention. In years past, several children and a few courageous adults held male bees and were fascinating by the buzzing sounds and vibrations generated by flight muscles that power their wings. In discussing the antics and activities of carpenter bees, I was heartened to learn that most folks take a “live and let live” approach to dealing with the carpenters. As one lady put it, “This is their world too, you know.” I do know, and well said.

When will periodical cicadas of Brood XIV make their appearance? Magicicada spp.

 

Almost-ready-to-emerge cicadas like this one lack dorsal black patches behind their red eyes.

 

In the past month, we explored the questions of how to know where periodical cicadas of Brood XIV might be seen, how to protect your trees from cicada damage and whether or not we should be worried about being bitten or stung by cicadas.  Recently, one of the most frequently asked questions about periodical cicadas is, “when will cicadas appear?” Bug of the Week has been tracking the life history of periodical cicadas for almost two decades, so let’s look at some historical data and see what it reveals.

The “when” question will often be answered with, “when soil temperatures reach 64 degrees Fahrenheit.” This answer comes from brilliant work performed almost 60 years ago by J. E. Heath who discovered that cicadas emerged when “soil temperature at 20-cm depth in seven locations averaged 17.89 C … regardless of date.” This answer holds fairly well even to this day. However, it is not always possible to know just when the magical 64 degrees at 8 inches below ground hits. We explored this in a slightly different way by observing the emergence of straggling Brood X cicadas in the DMV in 2020. In 2020, several locations reported sightings of impressive numbers of Brood X cicadas that appeared one year early. These cicadas are known as “stragglers”. Stragglers are periodical cicadas that emerge years prior to or after the major portion of their brood mates. Often, 17-year cicada stragglers emerge four years prior to the emergence date of rest of the brood. In 2017, Maryland Brood X stragglers appeared on May 14 in Columbia and Gaithersburg. In addition to emerging four years early, sometimes stragglers emerge one year early and this is exactly what happened in 2020. Using data collected in 2020 from the brilliant Cicada Safari App, the very first cicada out of the ground in the DMV was seen on April 19, just south of Towson, Maryland. This one was an extreme outlier. Cicada emergence really picked up in the DMV on May 14, and by May 24, 25% of emerging cicadas were out of the ground. By May 28, 50% of cicadas had emerged, and just few days later, on May 31, 75% of all cicadas had emerged in DC, Maryland, and Northern Virginia. So, if 2025 is anything like 2020, or previous years for that matter, cicadas will be regularly seen as a trickle in some parts of their range in late April or early May with a tsunami hitting in the last two weeks of May and early June as these teenagers are up and out for the Cicadapalooza. Here in the DMV in 2020, the last cicada to emerge was reported in mid-June. Due to a normal life span of two to four weeks, don’t be surprised to see adult cicadas alive and well into the waning weeks of June, but, sadly, in most locations by the 4th of July, their moment in the sun will be all but finished and nothing but a fading memory.

 

This graph shows the range of cicada emergence dates in Maryland in 2020. These periodical cicadas, early risers of Brood X cicadas called stragglers, emerged one year in advance of their brood mates that appeared in 2021. Note an extremely early riser in April with the vast majority of cicadas emerging in late May and early June.

 

Unfortunately for most of us in the DMV, cicadas are likely to visit only Botetourt, Lee, Russell, Scott, Smyth, Tazewell, and Wise counties in western Virginia this year, with no hope of seeing them in DC and little hope of a visit in western Maryland. But for other states ranging from Georgia to Massachusetts Brood XIV is expected. Of course, the emergence in Georgia will begin weeks ahead of the emergence in Cape Cod. Back in the days of Brood X in 2021, Georgia reported adults in late April but in northern parts of Brood X’s range in northern Illinois, the adult show didn’t get underway until late May according to iNaturalist.     

For seventeen years, nymphs of Brood XIV cicadas have been developing underground. While digging a hole in my yard years ago, I discovered a quartet of periodical cicadas about 14 inches underground. Notice their white eyes and uniformly tan bodies. Here we see a periodical cicada not quite ready to emerge resting at the top of its exit gallery beneath a cinder block. Just behind its red eyes, the dorsal surface of the cicada is uniformly tan. On the evening of its emergence, notice how the dorsal exoskeleton of the fully developed cicada nymph bears two distinct black patches just behind its eyes. I think these are really good clues to help figure out when cicadas are about to emerge in your area.

Note the black patches just behind the head of each cicada on the morning of their emergence.

On a more local level, how can we tell when the big jailbreak is close at hand? The images and video accompanying this episode provide some clues. For weeks prior to emergence, we witnessed almost-ready-to-go periodical cicadas peeking out from their galleries. In these images, notice that just behind the cicada’s brilliant vermillion eyes, the dorsal surface of the cicada’s exoskeleton is uniformly tan in color. On the evening or day of emergence, notice how the exoskeleton of the cicada bears two jet-black patches just behind its eyes. In more than a dozen emergences of periodical cicadas attended by the Bug Guy, this seems to be the clue that cicada emergence is very close at hand or underway. When you see these dark patches, the big show is about to begin. Get ready to enjoy!

Do cicadas bite or sting? What other mischief do they create?

 

Cicadas insert soda-straw-like sucking mouthparts called a beak or proboscis into plant tissues to obtain nutrients for growth and development. Adult feeding results in minimal damage to plants compared to injury caused when female cicadas use their ovipositor to slit branches. Into these wounds eggs are deposited in egg-nests. Eggs develop during spring and summer. Cicada nymphs will hatch from these eggs, drop to the earth, and develop underground for the next seventeen years.

 

In recent episodes we learned where Brood XIV cicadas would and would not be seen this spring. We also discovered what signs to look for in your yard as a presage to their grand appearance. This week let’s tackle a few questions that popped up in a recent conversation with the Weather Channel. Two of the most frequently asked questions regarding cicadas is “do they bite and do they sting?” Well, through my six decades of watching, catching, studying, eating, and photographing cicadas, my answer has been no, don’t worry about being bitten or stung by cicadas. However, following two messages from folks who listened to a television interview this week, I am scratching my head just a little bit about what cicadas can and cannot do with regard to biting and stinging. One viewer recounted an episode almost two decades ago when a cicada landed on their shoulder and pierced the skin leaving behind a zig-zag shaped mark. A second viewer shared an encounter with a cicada that attempted to probe her finger with its beak while she was holding the cicada during a “show and tell” demonstration with some children.

See the black proboscis or beak of the cicada between its front legs? Watch as it pushes its beak into the tree to find the vascular element called xylem which will be its source of liquid food for the next several weeks.

So, let’s dive into these questions about biting and stinging cicadas and see what might be afoot. We all learned in grammar school that one commonality of animals is that they are heterotrophs, that is, they cannot produce their own food but instead must eat other things for their sustenance. And when we think about animals eating, we think about biting, right? Biting usually involves something like what we humans do, jaws with mandibles removing chunks of food. Many insects like grasshoppers, beetles, wasps, and caterpillars have jaws that remove hunks of flesh or foliage as they feed. However, in many clans of insects, these jaw-like mouthparts have morphed dramatically through time into more soda-straw-like mouthparts, called piercing or sucking mouthparts, with the descriptive name of beak or proboscis. The beak has internal channels; one is used to remove liquid food from plants or animals which they feed upon, and another channel is used to inject saliva into the food item. Insects with sucking mouthparts include disagreeable rascals like bed bugs, mosquitoes, stink bugs, and lanternflies. Cicadas also have sucking mouthparts used to imbibe xylem fluid from plants on which they feed. So, do cicadas bite? Technically, you cannot bite with sucking mouthparts but you can suck and yes, cicadas do suck. Obviously, the next question is “do they suck on humans or pets?” The answer as far as I am aware is no. I have never heard of any human or animal losing blood to a sucking periodical cicada. These are obligatory plant feeders. The person mildly assaulted by a cicada shared that it did not break her skin. Also, she disclosed that the cicada had been confined for a long time and maybe it was tired of being held by a human. Who knows?

Young saplings and recently transplanted trees growing rapidly in the open are often heavily damaged by cicadas.

Well, what about stinging? Let’s dive into that. Stinging insects like bees, ants, and hornets, do so with an appendage at the tip of their abdomen called an ovipositor. Queens of these social insects use their ovipositor to lay eggs that hatch into workers. Workers are tasked with the onerous job of defending the colony. The ovipositors of defensive workers are connected to glands that produce venom, powerful chemical cocktails designed to bring intense pain to Winne the Pooh or other interlopers intent on raiding the colony for honey or brood. The ovipositor of most other insects is an appendage used to deposit eggs in a place where offspring can develop and thrive. As is the case with cicadas, ovipositors of these insects lack venom. Periodical cicadas use their ovipositor to cut slits into the tissues of plants, primarily trees and shrubs, where eggs of the next generation of cicadas develop before nymphs hatch and drop to the earth. As you might surmise, these ovipositors are stout and sharp enough to pierce the bark of a branch. Perhaps the person assaulted by a cicada was the unwitting victim of a misguided female cicada who mistook a human shoulder for a place to deposit eggs. Animal behavior is rife with mysteries and evolutionary mistakes, some for the better and some for the worse. If this assault was an attempt to lay eggs in a human rather than a plant, you can bet these foolish egg-laying genes will not last long in the reign of cicadas. 

Female cicadas use saber-like ovipositors to cut slits in the bark of small branches. These slits are called egg-nests. Watch as the female cicada moves her ovipositor in and out of an egg-nest where she deposits 20 to 30 eggs. She creates dozens of egg-nests which line small branches throughout the canopy of trees she visits. In some cases, weakened branches break and leaves die, creating so-called “flags” hanging throughout the crowns of cicada laden trees. Young saplings and recently transplanted trees growing rapidly in the open are often heavily damaged by cicadas. 

Wrapping trees in netting will prevent periodical cicadas from damaging branches of young trees.

My take is that the chances of being probed by the beak of a cicada or assaulted by a crazed, egg-laying female are very small. However, for the millions of homeowners that might be visited by periodical cicadas there is one potentially significant problem. This “dark side” of periodical cicadas manifests itself if you have small saplings or have recently installed young trees in your landscape. Egg-laying cicadas will slice branches to insert their eggs into egg-nests. This causes the tips of many branches to wither and sometimes die. Dying and dead terminals droop, resulting in a type of tree injury called flagging. Some injured terminals break and fall to the ground. Branches that do not break may eventually heal, but the wound-site may form a gnarly irregular swelling on the branch. Which plants are most likely to be affected? The bad news here is that periodical cicadas are broad generalists. Miller and Crowley (1998) studied 140 genera of trees at the Morton Arboretum and found more than half sustained injury caused by ovipositing females. Among the most severely affected were ones common to landscapes in the DMV, including Acer (maple), Amelanchier (shadbush), Carpinus (hornbeam), Castanea (chestnut), Cercidphyllum (katsura), Cercis (redbud), Chionanthus (fringe tree), Fagus (beech), Quercus (oak), Myrica (bayberry), Ostrya (hophornbeam), Prunus (cherry) and Weigela (weigela). Another study by Brown and Zuefle (2009) of 42 woody plant species added several new genera to the list and found all but 10 species were used by cicadas to lay eggs. Small rapidly growing trees with longer, more open branching habits found in young saplings were more heavily used for egg-laying. Trees at the edges of forests with rapidly growing branches exposed to sunlight often sustain more cicada injury. While ovipositional injury poses a threat to newly planted trees, for older and well-established trees flagging and limb breakage may occur in the short term, however, studies indicate that the long-term threat to tree vitality is minimal (Miller and Croft 1998).

How can you mitigate damage caused by ovipositing Brood XIV cicadas on young trees in your yard? Unfortunately, sometimes our knee-jerk reaction is to grab a can of insecticide and start squirting when we see a bug. In the case of periodical cicadas, studies have shown that the most effective deterrent to egg-laying cicadas is to wrap your saplings in netting that prevents females from laying their eggs. Ahern et al. (2005) found that linden saplings protected by netting with openings of 1 cm (0.4 inches) prevented cicadas from laying eggs whereas saplings treated with systemic insecticides or those left untreated received several hundred egg-nests along their branches.

Young linden trees protected by netting had virtually no egg-nests laid in their branches while those treated with a systemic insecticide or left untreated had hundreds of egg-nests deposited in their branches. Data from Ahern et al. 2005.

In future episodes we will explore when Brood XIV cicadas might appear and learn more about these strange and remarkable insects.

Will Brood XIV cicadas appear in my yard? Here are some clues

Perfectly shaped for moving soil, greatly expanded forelegs enable the mature cicada nymph to create a pathway to the world above ground.

Last week we broke some news that here in the DMV some will see Brood XIV cicadas this year (Virginia), others will not (DC), and some might (Maryland). If you are fortunate enough to live in one of the twelve states where Brood XIV are known to occur, how will you know if cicadas are about to grace your yard? As many of you know, periodical cicadas are quite patchy in their distribution. In my neighborhood in Columbia, Maryland, folks along my street had tons of Brood X cicadas back in 2021, but just a few streets away, nary a cicada was to be seen. Several factors feature into local distributions of periodical cicadas. Changes in land use are primary factors. Periodical cicadas depend on woody plants as key places to conduct their boisterous choruses, mating rituals and locations to deposit eggs that usher in the next generation. Although soil-dwelling nymphs can feed on roots of herbaceous plants, xylem fluids from tree roots support fantastic densities of cicada nymphs as they grow underground for seventeen years. If you live in a neighborhood where development has denuded trees and removed soil in the last seventeen years, your chances of Brood XIV emerging in your yard are slim. Likewise, if your house sprouted up in what formerly was a field of hay or corn, your chances of welcoming periodical cicadas are, well, not so hot. Habitat fragmentation and urbanization with attendant impervious surfaces and soil compaction are two factors thought to disfavor populations of periodical cicadas. In several locations in the eastern United States, populations have dwindled or been extirpated over the last two centuries.

As periodical cicadas complete their juvenile development, here are some clues to help you know if you will see cicadas this spring or not. First, if your landscape supported cicadas back in 2008, odds are excellent that you will see them again this year. If you have moved into a home sometime after 2008 and you live in one of the states where Brood XIV historically appears, simply ask one of your long-standing neighbors if they saw cicadas seventeen years ago. If you live in Georgia, Indiana, Kentucky, Massachusetts, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, or West Virginia, you can see which counties in your state reported Brood XIV back in 2008 by visiting the Cicada Mania website. There are also several clues you can see in the landscape around your home over the next month or so that signal the presence of cicadas. First, let’s talk about a glorious feast that is underway for small wild and domestic mammals as periodical cicadas prepare an exit strategy from their subterranean crypts. Four years ago, as a presage to the massive emergence of Brood X, a curious homeowner sent fascinating images of impressive excavations of turf beneath a fine old tree. The perpetrator of this crime was a pesky raccoon intent on digging for its dinner. The lawn was, well, just collateral damage on the way to a fine meal. While the identity of the subterranean morsel was never confirmed, this type of behavior is characteristic of many small mammals that will find cicada nymphs and adults irresistible this spring and go to great lengths to find them.

After feasting on periodical nymphs beneath my holly tree, this handsome fox headed for the hills and almost escaped my camera.

Also, during the early days of spring in 2021, the year of Brood X, while emptying some coffee grinds in the compost at 6:30 AM, I surprised a very handsome red fox in the process of excavating a thirty-foot-long patch of earth beneath my stately Burford holly. A couple quick turns of the shovel revealed several Magicicada nymphs about six inches below the surface of the earth. Casual site visits to my neighbors’ gardens and further inspection of my landscape revealed several locations where fox and friends had been busy in Columbia, Maryland enjoying cicada snacks. Both foxes and raccoons have excellent night vision, a must for their nocturnal forays, and an extremely keen sense of smell that allows them to detect prey beneath layers of fallen leaves and soil. These wild small mammals are not the only ones whose special creature powers include super olfaction. A dog’s sense of smell is estimated to be more than 10,000 times more acute than a human’s. And yes, if it hasn’t started already, soon inquiries will arrive posing the question: “Why is the dog digging up my yard?” Chances are good that Fido knows a good snack when he smells one. Please, just don’t let him eat too many.

How might you know if cicadas will emerge in your yard? Here are some clues. Small mammals like squirrels, foxes, racoons and skunks are on the hunt for cicadas, turning over the soil in lawns and beneath trees. In moist soils cicada nymphs sometimes build mud turrets over their exit holes and in other places vast numbers of round dime-sized holes will appear. Under stepping stones and flagstone walkways, numerous cicadas may be found in their galleries. Amazing expanded forelegs shaped by millions of years of evolution enable cicadas to move earth and shape their escape tunnels.

In moist soils like this, cicadas build mud turrets over their emergence holes.

Soon it will be time for a suburban safari to your backyard to spot additional signs of the arrival of periodical cicadas. Look for holes in the soil about the size of a dime within the dripline beneath trees that have been in the ground for seventeen years or more. Historically, oaks, maples, crabapples, and hollies seem to be the big winners in my landscape. In addition to holes, periodical cicadas often build domed caps or tubular extensions known as turrets over their escape tunnels. This may be more common in wetter soils. If your landscape includes stepping stones or flagstone pathways over soil, lift a few and you may discover lateral tunnels as cicadas encounter the impenetrable barrier and attempt to make their way to the edge of the barricade to reach the world above ground.

No holes under trees? Don’t panic, new holes may show up over the next several weeks. During past emergences of periodical cicadas, a common question has been, “how do cicadas moved about underground and how did they construct their exit galleries? The answer lies in the clever adaptations of their forelegs. Their forelegs bear greatly expanded femurs and tibias which act like the blade of a shovel to move soil. Millions of years of evolution for a life in two worlds, one underground and one above the earth, have perfected the tools necessary for cicadas to succeed in both. In upcoming episodes, we will learn more about these remarkable insects.

Will Brood XIV cicadas appear in the DMV? Yes, no, and maybe – Magicicada septendecim, Magicicada cassini and Magicicada septendecula

 

Will cicadaphiles in the DMV have a chance to see beautiful periodical cicadas near their homes this year? Yes, no, and maybe.

 

During the past two months, Bug of the Week’s peregrinations took us to the tropical rainforests of Belize to visit stingless bees, sassy assassin bugs, red rump tarantulas, headlamp beetles, incredibly fast whip spiders, fungus-loving leafcutter ants, and rapacious army ants. This week we hop-scotch fifteen hundred miles north to the DMV to check on the progress of Brood XIV (14) periodical cicadas. Last week journalists proclaimed the upcoming arrival of millions (or is it billions?) of cicadas set to emerge in a dozen eastern states. The appearance of periodical cicadas in the DMV this year looks like a definite yes, no, and maybe. According to the Cicada Mania website, a source of all things cicada, Virginia is a definite yes. Brood XIV is a brood of all three species of 17 – year cicadas, Magicicada septendecim, Magicicada cassini and Magicicada septendecula, that was last seen in 2008 in Botetourt, Lee, Russell, Scott, Smyth, Tazewell, and Wise counties. Unfortunately, the District of Columbia appears to be a definite no. While historical maps by Charles Marlatt and Roy Troutman appear to show Brood XIV in D.C., more recent compilations indicate that this is not the case.

Seventeen years ago, back in 2008, eggs of periodical cicadas hatched. After stretching their legs a bit, tiny nymphs dropped form tree branches down to the earth below. They entered the soil sometimes using the very holes from which their parents emerged but few weeks earlier. After sucking sap from plant roots for a few years, they grew to the size of a jelly bean. But just three years ago, they were almost an inch in length. In locations where they will emerge you can visit Brood XIV cicadas by carefully turning the soil with a shovel. After your visit, please return them to the soil and gently cover them with earth so they will emerge with the rest of their brood mates later in spring.

The maybe part comes with Maryland. Until very recently Maryland was listed in some sources as a state that would host Brood XIV cicadas in Washington and Allegheny Counties. There are several historical accounts of Brood XIV cicadas emerging in these counties dating back to the 1900s and 1940s. In 2008 along the Potomac River near Hancock, Maryland a localized ensemble of periodical cicadas was observed. Whether these were Brood XIV cicadas or not remains a mystery. Cicada researchers suggest that these may be stragglers from Brood X, time travelers that emerged four years behind the massive emergence of their brood-mates in 2021. This Bug Guy hopes that periodical cicadas are hanging on in Washington and Allegheny Counties. He plans to spend a lot of time wandering the C & O canal this spring and summer to catch a glimpse of Brood XIV or maybe the stragglers of Brood X. 

So, if you are concerned that periodical cicadas may not show this spring, put your fears to rest. In addition to Virginia, periodical cicadas will appear in parts of Georgia, Indiana, Kentucky, Massachusetts, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, and West Virginia. For the rest of us mostly east of the Mississippi, well, we will have to wait for another time.

We will explore much more about these remarkable creatures in upcoming episodes.

A Guide to Avoiding a Rodent Infestation in Your Massachusetts Home 

Aging homes, climate, and urban expansion all play vital roles in the rise of rodent infestations in homes. Mice and rats can squeeze through tiny openings to enter human spaces and cause any number of problems, including potential structural damage and the spread of dangerous germs.

Why Rodents Are a Growing Problem in Massachusetts

Data from the Woburn Daily Times shows that nearly 16% of Massachusetts’ households must deal with rodent issues. Compare that number to the national average of 11.6%, and it becomes clear that the Bay State is facing a substantial rodent infestation problem.

Boston routinely makes it onto the list of top 10 U.S. cities with rodent problems, but it’s not the only hotspot in the state. In December 2024, rodent issues shut down a movie theater in Methuen, and schools also had to implement rodent prevention plans due to high levels of mouse activity. The town of Swampscott was forced to enact rodent infestation strategies to deal with elevated rodent activity. Additional areas with high levels of rodent activity include Worcester, Essex, and Suffolk counties, all of which rank among the top 10 rodent hotspots in the U.S.

Why Massachusetts Homes Are Vulnerable to Rodent Infestations 

According to various reports, Massachusetts is the 15th most rodent infested state in the U.S. The average age of the homes is one of the factors that can contribute to this issue, and Massachusetts housing is among the oldest in the country. Although historic homes offer stunning architecture and charm, they can also bring an increased risk of pest infestations and require stricter residential pest control strategies. Dated construction techniques and aging building materials can lead to a higher number of entry points, making it easier for critters to slip inside.

Urban and Suburban Rodent Infestation Hotspots

Cities worldwide are experiencing increasing rodent populations. Dense human populations, warmer temperatures, and increased availability of food are among the chief factors driving high rodent populations in cities like BostonWorcesterCambridgeLowell, and others. Likewise, growing suburban populations are also experiencing higher numbers of infestations. Easy access to fields and wooded areas increases the risk of mice and rats entering human spaces. 

Seasonal Risks: When Rodents Are Most Active 

The Northeastern U.S. is more prone to rodent activity than areas in the south, largely because the colder climate sends rodents scurrying indoors in search of shelter. Many Massachusetts homeowners report increased activity during fall and winter, when rodents seek warmth inside sheds, garages, attics, basements, and other areas of the home.

Mice vs. Rats — What’s Invading Your Home? 

Identifying the rodents infesting your home is the key to effectively eliminating them. Explore some of the most common species in the state and get tips on how to differentiate them.

The Most Common Rodents in Massachusetts 

Typical Massachusetts rodent infestations are caused by the following species of mice and rats

  • House Mice: These mice, also commonly called brown mice or domestic house mice, nest in sheltered spots, including wall voids and attics. 
  • Deer Mice: These tiny critters tend to infest areas like pantries and kitchen cabinets, typically nesting close to food sources. 
  • White-Footed Mice: These rodents love nesting in hollow areas, including in attics, wall voids, and basements. 
  • Norway Rats: These rats, also sometimes called sewer rats, typically stick to lower-level areas, including basements, crawl spaces, garbage dumps, and spaces under buildings. 

How to Tell the Difference 

It can be challenging to differentiate between mice and rats. Understanding where they tend to nest is a good starting point. Knowing more about the characteristics of each species can also help you figure out the species in question.

  • House Mice: Three to four inches long with hairless tails and gray or brown fur 
  • Deer Mice: Five to eight inches long with deer-like coloring, including white fur on their undersides and darker fur on their backs 
  • White-Footed Mice: Five to eight inches long with reddish-brown fur, white bellies, bi-colored tails, large ears, and white feet 
  • Norway Rats: Gray-brown fur and up to 18 inches in length, including their hairless tails

Signs of a Rodent Infestation in Your Massachusetts Home 

Hint — the sooner you know you have rodents, the easier it will be to control the infestation. So, how can you spot a potential infestation?

Early Warning Signs of a Rodent Infestation 

Rodents are typically nocturnal, so you might not see live rats or mice scurrying about during the day. However, you might come across telltale signs of rodents, such as the following: 

  • Droppings, dark-colored pellets found near food items, in cupboards and drawers, and floors 
  • Scratching sounds in ceilings, walls, and other areas 
  • Gnaw marks on wires, food packaging, or structural elements 
  • Nesting materials like shredded paper and insulation are strewn about 
  • Greasy-looking runways where rodents frequently travel 
  • Stale, musty odors

The Risks of Ignoring a Rodent Infestation 

Ignoring the signs of an infestation, or missing them altogether, can have serious consequences. First, rodents pose a health risk and can contaminate foods and surfaces with dozens of potential pathogens. Contact with urine, saliva, and droppings can expose you and your family to illness-causing germs. Additionally, rodents are known to continually chew on everything, including wooden beams, walls, and wires. Beyond property damage, they are also rapid breeders, with mice having as many as six babies every three weeks.

How to Avoid a Rodent Infestation in Your Massachusetts Home 

Taking a proactive approach can help keep your home safe from these clever and messy pests. Homeowners can make a real difference by following important preventative measures and calling for professional help at the first sign of an infestation.

DIY Rodent Infestation Prevention Tips

  • Seal openings, including small holes and gaps around utility lines and pipes 
  • Eliminate access to food with strict sanitation and rodent-proof food storage 
  • Promptly fix plumbing leaks to remove water sources 
  • Eliminate clutter, which can encourage rodents by giving them ample places to hide and nest 
  • Clean up outdoor spaces and keep lawns mowed, trees and shrubs trimmed, and bird feeders far from the house

Why Professional Rodent Infestation Control Is the Best Solution 

For long-term residential rodent control, it’s critical to partner with professionals. Pest control pros have the education and training to identify the rodents infesting the home and deal with them accordingly. With help from the right professionals, you can achieve short-term success with efficient rodent removal and lasting control with preventive tips.

The Difference Between Pest Control vs Exterminator 

An Intro to Pest Control vs Exterminator 

You might hear the terms “pest control” and “exterminator” used interchangeably, but they are not actually the same thing. Although the two can overlap in some ways, each one primarily offers distinctly different services and approaches.

To make an informed decision for your home or business, it’s important to understand the differences between the two options. This will help you know exactly what to expect from the service you choose whether you’re seeking residential pest control or hiring an exterminator. 

What Is an Exterminator? 

Some of the earliest exterminators were the Ancient Sumerians. Way back in 2500 B.C., they used sulfur to eliminate insects. Today, exterminators still play a role in getting rid of unwanted pests.

What Does an Exterminator Do? 

As their title implies, exterminators kill pests. According to the Cambridge Dictionary, the official definition describes a professional who works to kill unwanted animals or insects. 

Common Pest Extermination Methods 

Using pesticides is frequently exterminators’ go-to solution. Provided the chemicals achieve the desired result, there may be little regard for tailoring the treatment to the pest. Likewise, the materials may be stronger and applied in a broader area than strictly necessary. 

When exterminators provide their services, which often include bombing, spraying, and fumigation, humans and pets typically must leave for a number of hours to avoid exposure to various toxic chemicals. 

What Is Pest Control? 

Until the latter part of the 20th century, all pest control services were lumped into the category of “exterminators.” However, pest control ultimately evolved from exterminators to take a more comprehensive approach that focuses on preventing pests, not just killing them. The idea of pest prevention dates to 300 B.C., when the Chinese first recognized that timing their crop planting could help reduce pest infestations. 

What Does Pest Control Do? 

Pest control professionals seek to understand the how and why of pest infestations, getting to the root of the issue to achieve long-term results. They also embrace technology and eco-friendly solutions, working to protect the environment. Although pest control still involves pesticides, companies use formulas targeted for specific pests as well as options that are less toxic to people and pets. Furthermore, they employ various additional methods to eliminate pests and prevent them from returning. 

Common Pest Control Methods 

Pest control professionals typically embrace Integrated Pest Management (IPM) practices, which aim to control pests using the least toxic methods possible with a heavy focus on prevention. Other methods include educating homeowners and businesses on preventative strategies like sanitation and proper food storage. Pest control services also use nonchemical methods like heat or extreme cold, biological control such as beneficial pests, and chemical control when necessary.

Key Differences Between Pest Control and Exterminator 

Exterminators typically offer one-off services, rarely with a guarantee, while pest control companies partner with homeowners and businesses, usually providing service guarantees. Some of the biggest differences between the two include variations in focus, approaches, and control methods. For example, exterminators offer a reactive, one-size-fits-all approach to pest control with a focus on killing the pests present, usually with harsh chemicals. In contrast, pest control professionals offer a customized, proactive approach designed for long-term success using chemical control as one of many options.

Key Focus

Exterminators focus on immediate removal of the insects or animals infesting the property. In contrast, pest control companies strive to eliminate infestations while also providing sustainable, long-term pest management. 

Approach

Exterminators take a reactive approach — you have a problem at-hand, and they will remedy it. Pest control professionals seek proactive strategies to stop infestations before they ever begin, using robust prevention methods. 

Use of Chemicals 

Because pest control companies take a holistic, long-term approach, they also tend to offer more environmentally friendly options. They target each treatment to the insect or animal and opt for the most effective, yet least toxic option available when using pesticides. An exterminator’s goal is to eliminate pests, and that approach often relies on chemicals only — many of which are harsh.

Long-Term Effectiveness

Exterminators offer a short-term solution to the problem but often don’t get to the root of why it happened. Pest control companies, on the other hand, partner with their clients and guide them to achieve long-term prevention and lasting results. 

Common Misconceptions about Pest Control and Exterminators

Exterminators and Pest Control Companies Are the Same 

Although they both deal with pests, the two types of companies are not interchangeable. Extermination kills the existing infestation. Pest control eliminates it and provides long-term preventative strategies for achieving lasting control.

Pest Control Doesn’t Use Any Chemicals 

Although pest control companies try to use other control strategies, including prevention, exclusion, and innovative techniques like applying steam, they also use chemical control. When using pesticides, pest control focuses on carefully choosing chemicals that will do the least harm possible to people, pets, and the environment.

Extermination Offers Complete Control Forever 

Extermination offers fast results and total elimination of pests that are present during treatment. In contrast, pest control tries to address the underlying issues causing infestations and attracting pests to achieve lasting success.

Pest Control vs. Exterminator: Which Is Right for You? 

Now that you know the differences between pest control and extermination, let’s dive into how to choose the right service for your circumstances.

When to Call an Exterminator

If you have a severe infestation, emergency pest problem, or an instance where you need immediate pest elimination, it might be wise to call an exterminator. At that point, the goal is to eliminate the problem and regain instant control.

When to Call Pest Control

However, if you want to eliminate pest problems before they begin and develop a long-term prevention strategy, a pest control company is the optimal option. Pest control is an excellent option for eco-conscious homeowners and businesses interested in sustainable pest control solutions.

Homeowners vs. Business Considerations

Residential and commercial pest control solutions serve the differing needs of homeowners and businesses. Each has unique requirements, with many businesses subject to local, state, and federal regulations that govern their approach to pest management.

Choosing the Right Pest Control Provider 

When choosing who to work with, there is a lot to consider. Although immediate results may sometimes be necessary, you should also consider implementing an ongoing pest control strategy. 

Why Long-Term Pest Control Is the Best Solution 

Long-term control relies on a proactive approach, which involves taking precautions before an infestation begins. While reactive pest control waits until pests are present, proactive strategies reduce the risk to prevent infestations and stop pests before they can cause problems.

What to Look for in a Pest Control Company 

Think of pest control companies as long-term partners in your battle against pests. You want customer service-oriented professionals you can trust. Consider the following qualities: 

  • Licensure and certifications 
  • Commitment to employee training 
  • IPM approach and eco-friendly control options 
  • Long-term approach with a focus on prevention 
  • Service guarantees with clear stipulations 
  • Positive testimonials and client experience
