Food premises are designed to store, prepare, and serve food efficiently. The conditions established for those purposes can make them highly attractive to pests. Restaurants, commercial kitchens, retail food stores, and food processing facilities face unique pest pressures that go beyond what most other commercial spaces experience.

Understanding why pests are attracted to food businesses, how infestations develop, and what risks they pose is essential for protecting food safety, maintaining compliance, and preventing small issues from becoming serious operational problems. Many food businesses rely on Integrated Pest Management strategies to reduce pest risk proactively while supporting food safety and compliance.

Understanding Pest Attraction in Food Premises

Food premises include any environment where food is prepared, handled, stored, or sold. This category extends beyond restaurants to include grocery stores, bakeries, food production facilities, cafeterias, and commercial kitchens of all sizes.

These environments naturally attract pests because they provide consistent access to food, moisture, warmth, and shelter. These are the same elements pests need to survive. Importantly, pest attraction does not automatically indicate poor management or unclean conditions. Even well run food premises can experience pest pressure simply due to the nature of their operations.

Because pests pose direct risks to food safety and public health, their presence is also closely tied to inspections and regulatory compliance. For food businesses, pest control is not just about removal. It is a critical component of risk management and prevention.

Why Food Premises Are High Risk Environments for Pests

Food premises present a combination of environmental and operational conditions that make them higher risk than most other commercial spaces. Food is present daily, equipment generates heat, water is used frequently, and staff movement creates regular access points throughout the building.

Moisture from sinks, drains, dishwashing areas, and cleaning processes provides hydration for pests. Warmth from cooking equipment and refrigeration motors creates ideal harboring spaces. Storage rooms, delivery areas, and waste zones further increase exposure if they are not carefully managed.

These risks exist even in facilities with strong sanitation practices. High volume operations, tight schedules, and constant activity can make it difficult to eliminate every opportunity for pest access. This is why pest management is often a key focus during food safety inspections and audits.

Key Reasons Pests Infest Food Premises

• Improper food storage and waste handling: Food that is not sealed properly or waste that accumulates during busy service hours can quickly attract insects and rodents. End of day cleanup delays or overflowing bins create short windows of opportunity that pests can exploit.
• Structural access points such as doors, vents, and drains: Frequent deliveries, open doors, and utility penetrations are part of daily operations. Over time, these access points allow pests to enter unnoticed, especially when buildings are in constant use.
• Sanitation gaps tied to cleaning schedules and peak hours: High traffic periods can push deep cleaning tasks later in the day. These gaps are usually related to timing and workload, not neglect, but they still increase pest exposure.
• Supplier deliveries and packaging transitions: Cardboard boxes, pallets, and shipments can unintentionally introduce pests into food premises. Storage and unpacking areas are common entry points when materials are moved quickly.

Pest Risks in Food Establishments and Decision Making

Pests in food establishments create risks that extend beyond inconvenience. From a health perspective, pests can contaminate food and surfaces, increasing the potential for foodborne illnesses. From a business standpoint, even a single sighting can damage reputation and customer trust.

Regulatory compliance is another critical factor. Pest activity is often flagged during inspections, and repeated issues may result in citations, corrective actions, and even operational disruptions. Certain seasons, particularly colder months, can increase indoor pest pressure as insects and rodents seek warmth and food.

For food business owners and managers, pest sightings should be viewed as early warning signals rather than isolated incidents. Addressing activity promptly allows businesses to correct underlying conditions before they escalate.

The Value of Identifying Pest Attraction Early

Identifying pest attraction early offers clear advantages for food businesses. Addressing conditions that support pest activity can reduce the severity and spread of infestations, lowering long-term remediation costs and minimizing disruption to daily operations.

Early intervention also supports stronger food safety outcomes. Clean, organized environments make it easier to detect changes, monitor trends, and respond before pests impact compliance or the customer experience. In many cases, proactive action prevents the need for more intensive treatments later.

How Food Businesses Can Reduce Pest Attraction

Reducing pest attraction in food premises starts with prevention, consistency, and awareness. Sanitation remains the foundation, but it works best when combined with structural attention, staff involvement, and ongoing monitoring.

Well-maintained facilities focus on sealing entry points, managing moisture, and implementing clear food storage practices. Staff training plays an important role by helping teams recognize the early signs of pest activity and understand how daily habits influence risk. Monitoring tools provides additional visibility, allowing businesses to track activity and respond strategically rather than reactively.

Catseye Pest Control works with food businesses to support pest resistant environments through prevention focused services and targeted solutions. By addressing pest attraction at its source and aligning pest management with operational realities, food premises can maintain safer, cleaner, and more compliant spaces year round. When expert guidance is part of the process, prevention becomes more effective and easier to sustain. Contact our team to take the necessary steps for pest prevention in your food business.

In previous episodes we visited tasty termites and beautiful butterflies during the daylight hours in the rainforest of Belize. This week we go dark on a nocturnal foray into the heart of a tropical rainforest. This escapade can produce memorable encounters. During one such foray we were amazed to see a beautiful brown scorpion turn a gorgeous blue-green when a trail guide moved a fallen leaf and cast the beam of a blacklight on the scorpion. Being a youth of the 60’s, I was instinctively struck to understand what my blacklight posters shared with this stinging eight-legged rainforest predator. It turns out that blacklight posters contain compounds, phosphors, capable of capturing the high energy photons of UV light and releasing their energy in longer and less energetic forms of visible light, producing dazzling, glowing hues. Scorpion glow results when UV light is captured by two compounds, beta-carboline and 4-methyl-7-hydroxycoumarin, found in the scorpion’s exoskeleton. Once captured, UV’s energy is released in the form of eerie blue-green florescence.  

In a series of clever studies, Dr. Douglas Gaffin and his colleagues discovered that the scorpion’s entire body may act as a photoreceptor or universal “eye” used to detect different levels of light. Light in the UV range directed at scorpions produced bouts of rapid movement. These researchers suggested that the scorpion’s whole-body “eye” might help it move to places where light no longer illuminates its body, such as locations beneath vegetation where the searching eyes of larger predators were less likely to spot it. Whole-body photoreceptors might also be used by scorpions to detect the waning light levels of twilight, the signal to exit hideouts and start their nocturnal hunt for prey.

A failed attempt to capture a rather large scorpion on the rainforest floor provided a memorable sting to my right thumb. A second successful attempt with my left hand let us get up close and personal with this powerful nocturnal predator. Its sharp stinger delivers a witch’s brew of neurotoxins and other pain-enhancing compounds. Under the glare of white and red flashlights the scorpion’s color was a chocolate brown. But under the beams of a UV-black light, the scorpion fluoresces an eerie blue-green. UV light receptors on the scorpion’s body may help it detect sunlight and initiate movement to dark hiding places during daylight hours, or they may help the scorpion detect the absence of sunlight, signaling the safe time to emerge from cover to hunt prey during the cloak of night.

The business end of the scorpion is the sting, an enlarged segment at the end of the scorpion’s tail that contains a venom gland and a needle-like poker to deliver the poison. The sting is used to immobilize and kill prey and as a means of defense against larger animals. For some inexplicable reason, I was moved to pick up a scorpion we discovered on a rainforest trail while searching for reptiles. My first attempt to grab the scorpion by its tail was a miss that resulted in a painful and memorable sting to my right thumb. The pain was similar to that of a large wasp or honeybee. It lingered for several minutes then dulled to a mild nuisance for a few hours.  A novel element of this misadventure was notable swelling to my thumb which lasted through the next day. As seen in the video, my second attempt to capture the scorpion using my left hand was a success. Holding this largish rascal was a bit scary but pretty good fun. I learned that scorpions move surprisingly fast, but the venom of this Centruroids scorpion is not generally life threatening. However, some relatives of Centruroids, including those in the genus Tityus, are very dangerous and their venom can be fatal to humans. This is not an endorsement for anyone to hold a scorpion as reactions to any foreign protein, including scorpion venom, can be serious and sometimes life-threatening.

On another tropical adventure in the rainforests of Belize I had the good fortune to encounter scorpions in a somewhat different context. After a long day of feeding mosquitoes and avoiding crocodiles with a group of students on a study abroad, the prospect of enjoying a little shut eye in the bunkhouse was most appealing. Unfortunately, one student climbed into her lower bunk bed and was surprised to see a rather impressive scorpion beneath the mattress of the upper bed just a few inches above her head. She tested the potency of the scorpion’s sting when she grabbed the one lurking over her bunk and was stung. She summarily hurled said scorpion out the door of her cabin. Her assessment of the experience: “It only hurt a little and that thing was really annoying me”. You go girl!

Following a week where Old Man Winter socked-it-to much of North America with bone chilling temperatures and mountains of snow, let’s return to the warm embrace of the rainforests of Belize where we last visited tasty conehead termites. Last week we met squirty termites in the dark rainforest. This week we move to a sunlit meadow to meet members of the brush-footed butterfly clan known as peacocks. Our first guest, the beautiful white peacock butterfly, Anartia jatrophae, is a resident not only of Central America, but also much of South America and as far north as Florida and Texas in the United States. The banded peacock, Anartia fatima, is also a resident of Central America and wanders into the United States, where it sometimes visits Texas and has been found occasionally as far north as Kansas.

Glorious banded peacock butterflies and pretty white peacock butterflies with spots on their wings use a rather small menu of tropical plants as food plants for their larvae. Males spar to defend patches of these host plants to court potential mates seeking food for their young. While I was unable to record these fast-moving battles, I hope that watching these tropical beauties might bring some cheer to you on these chilly and dreary winter days.

Throughout much of their range, peacocks can be found almost year-round in disturbed open meadows and swampy areas where food plants for the larvae are found. Food plants for caterpillars of the white and banded peacocks include water hyssop, blechum, frogfruit, and wild petunia. Tropical rainforests are among the most biologically diverse of all ecosystems on our planet, housing an astounding array of plant species. The Nature Conservancy estimates roughly 1500 species of flowering plants exist in a four-square mile area of tropical rainforest. The fidelity of female peacock butterflies to a relatively small number of plants on which she places her eggs has resulted in an interesting strategy employed by male peacock butterflies to secure a mate.

In a fascinating series of studies, Robert Lederhouse and his colleagues observed male white peacock butterflies patrolling roughly circular zones of vegetation in swampy areas in the Florida everglades. When other male peacocks, or any flying insects for that matter, entered the 15-meter diameter no-fly zone of a male, the interloper was summarily harassed and chased from the area. On closer examination, the scientists discovered water hyssop, the food plant needed for larval development, in each of the defended no-fly zones. A similar behavior of chasing away interloping males was also observed in the banded peacock butterfly. If you are a male peacock butterfly, it appears that one way to get a mate is to hang around the plant where the female must come to find requisite food for her babes.  Sounds a little like an episode of Seinfeld, doesn’t it? Remember the one called “The Bookstore” where Jerry provides dating advice to George? “GEORGE: I read somewhere that this Brentano’s is the place to meet girls in New York. JERRY: First it was the health club, then the supermarket, now the bookstore.” Why does it often seem that insects figure these things out before we do?

The holidays bring people together, fill homes with activity, and often disrupt normal routines. Once the celebrations end, many homeowners notice that their space feels cluttered, disorganized, or harder to keep clean than usual. A post-holiday cleaning checklist helps restore balance by addressing overlooked areas and the extra mess that naturally comes with hosting, decorating, and winter living.

Unlike routine weekly cleaning, post-holiday cleaning focuses on deeper resets and prevention. Increased food preparation, guests entering and exiting and moving through the home, stored decorations, and cold weather all create conditions that require more attention to detail. Taking the time to clean thoroughly after the holidays can improve indoor hygiene, reduce pest attraction, and make winter home maintenance far more manageable.

Why Post-Holiday Cleaning Matters 

During the holiday season, messes tend to build up in ways that aren’t immediately visible. Extra meals and diners lead to more crumbs and spills. Hosting guests also means higher traffic through rooms that may not usually see daily use. Decorations, boxes, and gift wrap are often stored quickly, sometimes without much organization.

Winter makes these issues more significant. As temperatures drop, pests look for warmth and reliable food sources indoors. Even small amounts of debris or clutter can create inviting conditions. Kitchens, storage areas, guest rooms, and garages are especially vulnerable during this time.

A thorough post-holiday cleaning helps homeowners catch these problems early. Addressing hidden messes now reduces the likelihood of pest issues later in the winter and helps keep the home healthier overall.

Post-Holiday Cleaning Checklist: Room by Room

Approaching post-holiday cleaning room by room makes the process more effective and less overwhelming. The following checklist highlights the areas that require the most attention after the holidays.

Kitchen and Food Storage Areas

• Clear out leftovers and expired items and wipe down refrigerator shelves, drawers, door seals, and pantry shelves.
• Reseal dry goods, clean up crumbs and spills, and sweep and mop floors, including under appliances.
• Empty, clean, and deodorize trash and recycling bins to remove food residue and odors.

Holiday cooking increases the chances of crumbs and spills collecting in hidden areas. Addressing the kitchen early helps eliminate one of the most common sources of winter pest attraction.

Living Room & Common Spaces

• Vacuum carpets, rugs, and upholstered furniture and dust baseboards, shelves, and electronics.
• Wash or shake out throw blankets, pillows, and other fabric décor before storing.
• Pack holiday decorations into clean, sealed containers rather than loose boxes.

These shared spaces often see the most activity during the holidays. Fabric items and stored decorations can easily trap debris if not cleaned properly before being put away.

Guest Bedrooms & Luggage Storage

• Wash guest bedding, blankets, and mattress covers and vacuum floors and mattresses.
• Check closets, luggage storage areas, and under beds for forgotten items or debris.
• Remove temporary clutter and return the room to regular use or proper winter storage conditions.

Guest rooms may not be used often during the rest of the year, which makes it especially important to clean them thoroughly before closing them off for winter.

Trash, Recycling, & Storage Areas

• Break down and remove cardboard boxes, wrapping paper, and excess packaging.
• Clean trash cans and recycling containers to eliminate residue and odors.
• Organize garages, basements, and storage rooms using sealed bins instead of loose boxes.

Reducing these materials significantly lowers the risk of pests settling in during colder months.

Seasonal Considerations After the Holidays

Winter changes how homes function. People spend more time indoors, storage areas fill up quickly, and ventilation is often limited. All of these factors make cleanliness and organization more important than usual.

The period immediately following the holidays is a common time for homeowners to notice pest activity indoors. Prioritizing cleaning food-related areas, disposing of waste properly, and organizing storage spaces can make a noticeable difference. 

Benefits of a Thorough After-Holiday Home Reset

Completing a post-holiday cleaning checklist does more than improve how your home looks. During winter, when homes are closed up and pests are more likely to move indoors, a thorough reset helps support a healthier and more manageable living environment.

By removing food residue, excess moisture, and clutter, homeowners reduce the conditions that attract insects and rodents. Clean, organized spaces also make it easier to spot early signs of pest activity, such as droppings, damaged packaging, and small gaps along walls and baseboards. Addressing these details early can help prevent minor issues from becoming larger problems later in the season.

A thoughtful after-holiday reset also simplifies winter home maintenance. When key areas are clean and organized, it’s easier to stay ahead of potential concerns and avoid the need for more extensive intervention down the line.

Supporting a Pest-Resistant Home After the Holidays

Post-holiday cleaning is an important first step in protecting your home during winter, but pest activity can still occur as insects and rodents look for warmth and shelter this time of year. Even well-maintained homes can experience pest pressure as insects and rodents seek warmth, food, and shelter after the holidays.

Professional pest inspections can help identify activity that may not be obvious during routine cleaning, particularly in kitchens, storage areas, basements, and common entry points. Addressing concerns early helps prevent small issues from turning into larger infestations.

Catseye Pest Control works with homeowners to support clean, pest-resistant homes by providing prevention-focused services and targeted solutions. If post-holiday cleaning reveals concerns or raises questions, having an experienced team to guide your next steps can make winter home care simpler and more effective.

As the wicked winter tightens its grip on much of North America, let’s take another trip to somewhere warm. We recently visited pretty orchid bees, hungry leaf beetles, and squirty froghoppers in the cloud forest of Costa Rica. This week we travel some 800 miles north to the rainforest at Toucan Ridge, Belize. In this lush green paradise warm temperatures and abundant rainfall make this one of the most productive ecosystems on the planet. Rapidly growing trees and shrubs provide a bounty of food for legions of plant-eating insects, reptiles, birds, and mammals. However, these vegetarians alone cannot devour the enormous quantity of plant material produced. Plant debris would soon bury the jungle were it not for work of another group of plant eaters, the termites. Termites are remarkable creatures that consume both living and dead plant material in the tropics. To utilize the nutrients tied up in plants, termites rely on a hearty gut microbiome of symbiotic bacteria and, in some primitive species, protozoa, to help digest the refractory plant material called cellulose.

Termites have an unusual and rather crude way of passing these vital microbes from one termite to the next through 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! The transfer of liquids from one termite to the next is also a way of disseminating chemical messages called pheromones that regulate the development and behavior of termites within the colony.

While adventuring along a slippery mountain trail with 18 adventurous students, we happened upon a large nest of conehead termites. Our local Belizean trail guide shared lore of the importance of termites to the ancient Mayan people. Mayans used termites as bait for fish in a way known only to them. Mayans crushed and smeared termites on their skin as a natural repellent for biting flies like mosquitoes. Mayans also consumed termites as a source of nutrients. Our Belizean guide invited us to sample termites to learn why so many insects, birds, and mammals seek a termite buffet.

Along a rainforest trail we encountered a large aerial termite nest. Our Belizean guide opened the nest and invited us to sample termites to learn why so many insects, birds, and mammals seek a termite buffet. By holding his hand against the hole in the nest, he collected several nozzle-headed soldiers that had issued forth to defend their colony.  After our guide dined on a few, several bold students and one professor sampled the tiny defenders. After plucking a few workers from the colony and savoring each morsel, I found the delicate flavor reminiscent of carrots. Little wonder the Mayans enjoyed them. Others in our group did not share my assessment. Some quipped that termites tasted, well, like bugs. 

To demonstrate this point, our guide made a platter-sized rent in the termite nest. By holding his hand against the hole in the nest, he collected several nozzle-headed soldiers that had issued forth to defend the nest. After our guide dined on a few, several bold students and one professor sampled the tiny defenders. After plucking a few workers from the colony and savoring each morsel, I found the delicate flavor reminiscent of carrots. Little wonder the Mayans enjoyed them. Others in our group did not share my assessment. Some quipped that termites tasted, well, like bugs. 

Termites are part of an elite group of social insects that include the ants and several wasps and bees. Social insects such as termites and ants have a distinct division of labor with a caste system that includes specialized workers, soldiers, and reproductives. Termite reproductives are called kings and queens. These long-lived queens produce thousands and thousands of eggs during the course of their lives, which can span several decades. Termite queens are the longest lived of all insect species. Termite kings live only long enough to mate and they die soon thereafter. While Tom Petty lyricized that it was good to be king, from the longevity standpoint it’s better to be queen in the termite realm.

This week we return to the mystical cloud forest of Monteverde Costa Rica where, in the last two episodes, we met beautiful golden frog hoppers and rolled-leaf hispine beetles that make beautiful heliconia plants their meal and home. In a stylish landscape along a high mountain road, we saw some large busy bees visiting beautiful purple porterweed. At first glance these appeared to be busy bumblebees, but with a little help from iNaturalist, we learned that these were large orchid bees in the genus Eulaema. In addition to pollinating porterweed, large orchid bees, including Eulaema, are important pollinators of a wide variety of orchids including one of my favorites, the second most expensive flavoring in the world, vanilla. While female orchid bees collect massive loads of pollen to feed their young, male orchid bees have evolved remarkable morphological structures and equally clever behaviors to woo their mates. On a section of their hide leg called the tibia, males evolved a greatly expanded hollow pouch. This hollow pouch has an opening to the air to release fragrances called perfumes. Let’s see what this is all about.  

Here’s a little backstory. In the dating game of humans, odors make a difference. Does anyone really want a stinky partner? Apparently not. For centuries humans have used fragrances to grab the attention of a potential mate. The global perfume industry is valued at more than 50 billion dollars annually. Guess what, male orchid bees have also figured out that the right odor can make you a winner in the mating game.

Male orchid bees visit sources of volatile scents in a wide variety of places including flowers, tree sap, resin, fungi, and other places to collect several different fragrances. How do they collect these perfumes? Male bees secrete droplets of lipid compounds from their mouthparts onto the surface of a flower or other source of odors. Various scented compounds are absorbed into the lipid droplets. These droplets are then collected and stored in the hollow chamber of the expanded tibial pouch of the hind leg. During courtship the male orchid bee fans its wings, causing the fragrances stored in the hind leg to become airborne. The unique blend of the male’s perfumes attracts potential mates, enabling female orchid bees to recognize males of her species and to choose that special someone to be the father of her offspring. I must wonder if orchid bees have a lesson here for us. 

In the cloud forest of Monteverde, large bees visit purple porterweed. Although resembling bumble bees, these beauties are orchid bees in the genus Eulaema. In addition to pollinating porterweed, Eulaema pollinate a wide variety of orchids including one of my favorites, vanilla. They sip nectar through a remarkably long proboscis, also called a tongue. While female orchid bees collect massive loads of pollen to feed their young, male orchid bees collect fragrances from many sources and store them in perfume pouches on their hind legs. To attract a mate, the male bee fans its wings, releasing his perfume into the air. Female orchid bees use these odors to recognize males and choose just the right mate to father their offspring.

Last week we visited beautiful Heliconia plants where we met some very pretty Golden Froghoppers as they sipped sap from leaves of Heliconia. This week we return to the lovely Heliconia plant to explore strange patterns of herbivore feeding on their leaves. These marks were created by some unseen herbivores that scraped away leaf tissue from the surface of the tender green leaves. These interesting patterns included small linear rows of missing tissue and larger isolated jelly-bean shaped translucent scars on the leaves. These marks were the handiwork of a curious group of leaf beetles, Chrysomelidae, known as rolled-leaf hispine beetles.

In tropical regions of the Americas more than 180 species of rolled-leaf hispine beetles have been described. In addition to Heliconia plants, several other members of the ginger family serve as hosts for rolled-leaf hispines. While the star of this week’s episode feeds on the unfurled leaves of Heliconia, other members of the clan eat tissues of flower bracts and leaf petioles. For Cephaloleia spp. we visit this week, life begins in a tubular leaf-scroll where female beetles deposit eggs between the rolled layers of an unfurled Heliconia leaf.  These eggs hatch into extraordinarily flattened larvae with a perfect body shape for life between the appressed layers of a rolled leaf. Their mandibles scrape soft, nutritious tissue from between the veins of Heliconia leaves. Their feeding behavior, termed “strip-mining”, is responsible for the linear feeding patterns seen on unfurled leaves.

Beetle larvae glide across the surface of the leaf on unseen legs beneath their body. Larval locomotion is strangely reminiscent of the movement of a slug or snail. Larvae of Cephaloleia pupate in a nook or cranny of the Heliconia plant before emerging as adults that return to the safety of a rolled leaf to feed. Adults create larger feeding marks on the leaf surface, as do fully developed larvae.

This week we return to the beautiful Heliconia plant to unravel the mystery of some strange feeding marks on its leaves. With no one home on the surface of an expanded leaf, unfurling a rolled-up leaf revealed a hungry rolled-leaf hispine leaf beetle and its feeding wounds on the leaf margin. On the inside of a more mature leaf-roll, a young beetle larvae glides over its older cousin on six tiny legs hidden beneath its body. Partially unrolling the scroll-like Heliconia leaf sent this leaf beetle scampering for the cover of a furled section of the leaf. Mystery of strange feeding marks on Heliconia solved.

In Costa Rica, some species of Heliconia are home and tucker to several species of rolled-leaf hispine beetles. In addition, the number of hispine beetle species increases with the geographic range of their ginger-family host plants, physical size of the plant species on which they feed, and abundance of plant hosts in an area. For Costa Rican Cephaloleia, life is on a roll in a roll.

As the holiday season draws to an end and the chilly grip of old man winter settles into the DMV, it’s time for Bug of the Week to head to warmer realms to visit insects and their kin in tropical places. Over the next several weeks, we will meet relatives of our native Maryland insects that enjoy warm weather somewhere else on planet earth. Our first stop will be the cloud forests of Costa Rica. Here we will meet some of the fascinating insects that make their home on the beautiful Heliconia plants found throughout tropical regions. Our first delight is the Golden Froghopper.

Froghoppers are a large family of insects technically known as Cercopidae.

Beautiful Heliconia plants are home to many insects in the tropical rainforests of Costa Rica. Gorgeous Golden Froghoppers can frequently be seen strolling across Heliconia leaves and dining on their nutritious sap. Excess fluid discharged from their rear-end is called honeydew, and it rains down on plants and slow-moving people below. Maybe this is yet another reason it rains in the rainforest.

Immature stages of froghoppers produce a bubbly concoction called spittle. Unsurprisingly, they are called spittlebugs. Spittle is a fairly innocuous mix of excess plant fluid voided by froghopper nymphs. Proteinaceous glandular secretions and air bubbles introduced by clever contortions cover the body of the nymph. The spittle serves to keep the developing nymph moist and insulated from extreme temperatures. It also may serve as a deterrent from attack by stinging parasitoids and hungry predators. Would self-respecting birds really wade through a glob of spittle in search of a buggy meal? I think not.

After molting several times within their bubble home, nymphs turn into winged adults. Adults suck plant sap to obtain nutrients and excrete excess sap in the form of honeydew, as do other sap-suckers including aphids, scale insects, and lanternflies.

Many adult froghoppers like those found in the DMV sport rather drab colors of gray or brown or cryptic shades of green and are not often seen during casual excursions to the garden. However, in the tropical rainforests of Costa Rica froghoppers can be stunning, like the gorgeous Golden Froghopper. Most spittlebugs and froghoppers cause no economic damage. While you may not have a chance to visit beautiful froghoppers in the tropics, next spring when you walk in the meadow, fear not the spittle and take a moment to brush back the bubbles and enjoy these curious sap-suckers.

Overview of Eco-Friendly Pest Control Methods

Eco-friendly pest control balances the need to eliminate pests with the desire to do the least harm to the environment, all while protecting people and pets. Catseye Pest Control understands that balance and offers innovative chemical and non-chemical treatments that safeguard households while effectively eliminating pests. 

Some of the key takeaways to consider include the following:

• Integrated pest management offers robust solutions and long-term success.
• Pest prevention is among the most effective strategies homeowners can undertake on their own, including the use of natural pest repellents.
• Humane mouse traps may be effective for small infestations, but exclusion offers greater protection. 
• DIY eco-friendly options may not be sufficient, particularly for widespread infestations, hazardous or damaging pests, or commercial properties.
• Consulting with a professional can ensure effective elimination while still using eco-friendly, low-toxicity strategies.

Integrated Pest Management (IPM) as a Sustainable Framework

Integrated pest management (IPM) is the gold standard of eco-friendly pest control and one of Catseye’s core strategies. This prevention and maintenance-focused approach offers an effective way to get rid of pests without damaging people, pets, or the ecosystem at large. 

Our four-pronged approach begins with a thorough inspection of the home. This allows technicians to identify pest activity, how pests enter, and the conditions that may contribute to the infestation. After identifying the pest and why and how they are entering, technicians customize their treatment plans, which may include structural repairs, monitoring, and low-toxicity treatments, depending on the situation at hand. 

Most of all, IPM represents a solid framework and a partnership that allows homeowners and professionals to work together to achieve a pest-free home.

Some of the pest control measures incorporated in IPM include the following:

• Biological control: Uses pests’ natural enemies to curtail their population
• Cultural control: Makes the home less hospitable by removing what pests need to survive, including food, water, and shelter
• Physical control: Removes pests and uses barriers to keep them from returning
• Chemical control: Implements “last resort” chemical treatments when necessary, typically as part of a larger strategy to prevent infestations and achieve long-term control

Natural Pest Prevention Techniques for Residential Properties

Prevention can save money and help homeowners avoid the need for strong chemicals. One of the most effective techniques falls under the IPM umbrella: cultural control. This strategy removes the resources that pests need to survive. As a result, it’s possible to reduce the risk of attracting pests in the first place. 

The Environmental Protection Agency (EPA) provides detailed guidance on preventative measures, including removing all sources of food, water, and shelter. That means clearing clutter, which provides easy areas for pests to hide, nest, and breed. Additional steps include the following:

• Storing food, including pet food, in rigid, tightly lidded containers, such as plastic, glass, or metal
• Regularly removing garbage from the home and placing it in pest-proof receptacles located at least 50 feet from the exterior of the home
• Fixing leaks promptly and remove any sources of standing water, such as clogged gutters
• Closing any cracks, crevices, or gaps around pipes and utility intrusions
• Covering holes and vents with wire mesh
• Checking cardboard and grocery items before bringing them indoors to avoid inadvertently introducing pests into the home
• Routinely vacuuming, cleaning up spills and crumbs, and washing dishes

Humane Mouse Traps and Non-Lethal Rodent Management

A 2023 study published by the National Library of Medicine shows that live traps often catch mice effectively. When studied in comparison to glue traps, live traps captured mice 75% to 91% of the time. 

Catch and release traps are a non-lethal option. They have one opening with a door that the mouse will trigger to close once it enters the trap. The mouse can then be relocated out into the wild. They typically come in one of two types: single mouse and multi-mouse traps.

Although these traps can help catch mice, they won’t help eliminate a widespread infestation. They are best for early signs of rodent activity before mice have a chance to establish their nests. If you consistently catch mice but also continue to see signs of an ongoing infestation, such as fresh droppings, it may be time to consult professionals.

Rodent and Wildlife Exclusion

One very effective rodent control measure is exclusion, which is the practice of closing off potential entry points to prevent mice and rats from entering. Wildlife exclusion systems like Cat-Guard provide a permanent, chemical-free, humane barriers. They offer targeted protection homeowners can install in one or more vulnerable areas, such as: 

• Attics and rooflines
• Foundations and windows
• Low-clearance spots like decks and sheds 

Natural Insect Repellent Options and Low-Toxicity Alternatives

One popular low-toxicity, natural solution for prevention is oil of lemon eucalyptus (OLE), not to be confused with lemon eucalyptus essential oil. OLE comes from the Australian lemon-scented gum tree and contains an active ingredient known as p-menthane-3,8-diol (PMD). It’s classified as a biopesticide and has the potential to provide five to seven hours of protection that is similar to DEET. It’s generally safe for pregnant women and children ages 3 and older and helps repel biting insects like ticks and mosquitoes.

A few additional natural insect repellent options include the following:

Essential Oils

Citronella and other citrus-based essential oils can help repel mosquitoes, flies, fleas, and mites. Garlic oil repels ticks, as does thyme, which also repels fleas and mosquitoes. Lavender and cinnamon may help keep areas mosquito-free. Peppermint essential oil may also be a good weapon against ants, flies, mosquitoes, and spiders. 

Homeowners can make their own repellents by mixing 10 to 20 drops of essential oils with 2 ounces each of distilled water and distilled white vinegar. Alternatively, they can make a repellent spray using one part essential oils mixed with 10 parts witch hazel in a spray bottle. 

Insect Repellent Plants

Inside or outdoors, some plants contain components that give off scents that ward off pests. Examples include:

• Chrysanthemums: These pretty flowers contain the repellent pyrethrum and ward off cockroaches, bed bugs, ants, fleas, and ticks.
• Rosemary: This aromatic foliage helps keep pests like snails, Japanese beetles, and carrot flies out of the garden. 
• Basil: This herb’s scent helps keep the garden free of aphids, mites, mosquitoes, and flies. It can also prevent insects from coming indoors if planted near entryways.
• Lemon thyme: This fragrant herb can help keep cockroaches, termites, and mosquitoes away.

When Eco-Friendly Methods Are Not Enough and Professional Support Is Required

Not all eco-friendly methods are equally effective. Natural approaches can offer effective prevention and control, particularly for small pest issues. However, commercial properties should contact professionals immediately to avoid issues with noncompliance related to health and safety regulations. 

Additionally, research suggests that 67% to 75% of homeowners who try solving pest problems on their own end up turning to pest control professionals anyway. Choosing the right treatment method, regularly repeating applications, and routine monitoring can be time-consuming, but these steps are critical for success. 

So, what is the trigger point that lets homeowners know it’s time to consult with a pro? 

• Persistent infestations: Signs of new and ongoing pest activity that continue beyond one to two weeks suggest that current strategies are not working.
• Widespread infestations: Professionals have the equipment and training to deal with large-scale pest infestations.
• Presence of hazardous pests: Termites, rodents, fleas, bed bugs, and cockroaches can be some of the most difficult infestations to manage. They also pose potential risks to human health and safety and could create structural damage.

This week we dive into the Bug of the Week mailbag and turn back the clock a few years to learn about some fantastic aphids, called giant bark aphids and giant willow aphids. The giant bark aphids and attendant ants were discovered on limbs of a beautiful oak tree near the Chesapeake Bay.

In addition to oaks, giant bark aphids are found on hickory, walnut, and beech, to name a few. Several years ago, on the campus of the University of Maryland, giant bark aphids and giant willow aphids were discovered on the bark of a magnificent beech tree and a weeping willow tree on campus. Here are their stories. 

Giant Bark Aphids by the Bug Guy

‘Twas the week before Christmas and what did I see,

Giant bark aphids on a leafless beech tree. 

Aphids are not known for their very large size,

But these babes on beech trees win the “big-aphid” prize. 

These serious sap-suckers spent several past weeks,

Sipping plant sap from branches through very long beaks. 

Aphid moms suck sweet phloem by night and by day,

And turn sap into nymphs – born alive, by the way. 

These strange spawning efforts are quite something to see,

Bug geeks call this birth-trick viviparity. 

In the waning of fall, cold winds start to blow,

And these gals change their plan. They just seem to know. 

No more birthing youngsters on twigs in the cold,

They lay eggs on branches, many thousand all told. 

Braving icy winds and the season’s first snow, giant willow aphids try to squeeze out one more generation before Old Man Winter puts them to rest.

Tiny black eggs seem to be a perfect life stage,

To brave wicked winter when vicious storms rage. 

And if aphids can hope, their fondest hope must be,

That no predators find their eggs on the leafless beech tree. 

Fear not giant aphids, be glad and be happy,

In spring eggs will hatch when beech trees get sappy.

 

Happy Holidays from Bug of the Week!
