Month: October 2025

Rhode Island may be the smallest state in the United States, but it is big on charm and offers a wonderful place to live and work. From its coastal towns to its vibrant cities, the state boasts more than 1.12 million happy residents.

Rhode Island’s mix of coastal towns, historic cities, and wooded neighborhoods creates ideal conditions for insects, rodents, and nuisance wildlife year-round. From Providence and Newport to Warwick and Pawtucket, homes and businesses face challenges from insects, rodents, and nuisance wildlife.

For more than three decades, Catseye Pest Control has protected New England properties with safe, eco-friendly treatments and long-term prevention strategies. Our licensed technicians understand the unique pest pressures of Rhode Island’s coastal climate and deliver customized solutions that keep properties pest-free throughout every season.

Commercial Pest Control 

Pest control is a must to keep your Rhode Island business’ employees, customers, and reputation safe. Catseye’s commercial pest control services are designed to protect employees, customers, and property while ensuring full compliance with state health codes and safety regulations.

Wildlife Removal and Prevention

Rhode Island is not a stranger to nuisance wildlife. When common invaders such as squirrels, opossums, raccoons, skunks, and bats make their way onto residential or commercial properties, professional help is critical. These critters often seek shelter, food, and water inside human structures, leading to potential problems ranging from disease transmission to structural damage.

In Rhode Island, relocating wildlife independently is prohibited. Working with the knowledgeable professionals at Catseye ensures that animals are safely and humanely removed according to all regulations. Additionally, we work with residents and owners to help prevent them from returning.

Exclusive to Catseye, Cat-Guard Exclusion Systems, which are rigid, chemical-free barriers, provides targeted protection to safeguard homes and buildings. These systems keep birds, rodents, and other wildlife out permanently.

Year-Round Protection Plans 

Year-round pest control programs are essential for creating ongoing peace of mind and freedom from pests. Available for both homes and businesses, the ongoing visits included in these programs consist of thorough inspections, preventative treatments, and removal and cleanup of identified pest activities.

Pest Challenges Unique to Rhode Island 

Rhode Island’s mix of coastal weather, wooded suburbs, and dense urban neighborhoods makes it a hotspot for pest activity year-round. The state’s mild winters and humid summers create ideal breeding conditions for insects and rodents, while its historic homes and waterfront properties provide countless entry points for unwanted pests.

Seasonal Pests in Rhode Island 

While some pests, like rodents and cockroaches, remain active all year, others surge during specific seasons. Understanding these patterns helps residents take preventative action before infestations begin. Some of the biggest seasonal threats include:

• Ticks: Activity has been rising in recent years, with tick season often peaking in the warmer months of May through July. Ticks can emerge whenever temperatures rise above 40 degrees Fahrenheit. 
• Mosquitoes: These warm-weather nuisances can cause more than just itchy welts. Mosquitoes can transmit various diseases, including Eastern Equine Encephalitis, West Nile Virus, and the Zika virus. Rhode Island Department of Health cautions that mosquitoes are sometimes active through October.
• Rodents: Many homeowners and businesses report seeing rodents once the weather cools down, and mice and rats begin looking for shelter for the winter. Rodents can transmit many illnesses, including Hantavirus.
• Ants: These scavengers often make their way indoors in search of food, potentially carrying illness-causing pathogens with them. Ant activity typically decreases during winter, but it can remain high through fall as these insects look for shelter.
• Termites: Subterranean termites, which can cause massive structural damage when infestations go unnoticed, are active across Rhode Island. Peak swarming season, when residents are most likely to spot termites, occurs during the day from March through May.

Regional Concerns

Rhode Island’s woodlands, shrublands, and relatively warm waters make it a favorite for many migratory birds, reptiles, amphibians, and mammals. Some of the most common nuisance wildlife include raccoons, opossums, squirrels, bats, Canada geese, coyotes, and foxes. Moisture-loving pests like termites, silverfish, and cockroaches are also a concern in Rhode Island and throughout much of New England.

State-by-State Pest Control Expertise 

Every state, city, and town — as well as every property — has unique conditions, making it essential to partner with pest control experts with local expertise. The Catseye team offers just that, with service locations throughout New England and experience working within each locale. 

• Rhode Island: Thanks to its coastal climate, moisture-related pests like termites, mosquitoes, carpenter ants, and cockroaches are among the most common pest problems in Rhode Island.
• Massachusetts: Urban areas like Boston are prone to rodents and cockroaches. Additionally, suburban and rural areas are experiencing an uptick in tick activity and often have to deal with ants, spiders, stinging insects, and nuisance wildlife. 
• New Hampshire: With more than 4.7 million acres of forest land, New Hampshire has to address nuisance wildlife as one of its most common pest problems. Insects like ticks, mosquitoes, stinkbugs, and Asian ladybugs are also problematic.
• Connecticut: With temperatures in Connecticut warming over the past decade, heavier rains and earlier springs have led to pests like ticks and mosquitoes emerging sooner. Other common pests include bed bugs, ants, spiders, and termites.

Pest Control in Rhode Island 

Whether homes and businesses are on the coast or in the city, Catseye understands the types of pests Rhode Island owners may face. Additionally, we partner with you to provide tips and tricks to keep pests gone for good.

Comprehensive Services: We provide residential and commercial programs to eliminate insects, rodents, and nuisance wildlife. 

Eco-Friendly, Low Toxicity Solutions: Catseye uses an Integrated Pest Management (IPM) approach, with an emphasis on prevention and safe treatment options for your Rhode Island home or commercial property. 

Excellent Customer Service: Friendly, knowledgeable technicians provide a free, thorough inspection and customized treatment plans in the field.

Why Work with a Professional Exterminator 

A 2022 study from Zevo and OnePoll revealed that 66% of Americans would do “nearly anything” to eliminate pests. It’s common to reach for a trap or off-the-shelf bug spray to try to tackle pest problems on your own — and the same survey revealed that homeowners spent an average of $177 on homemade concoctions — with only 54% reporting some degree of success. Do-it-yourself methods may seem convenient, but they rarely address and handle the root of the issue.

Benefits of Choosing Licensed Experts 

Working with a licensed exterminator means your pest problem is handled safely, effectively, and permanently. Certified technicians are trained to identify the source of an infestation, apply professional-grade treatments correctly, and prevent pests from coming back. They also understand the biology and behavior of each species, allowing for precise, targeted solutions that store-bought products can’t achieve. 

Beyond better results, licensed experts protect your home, family, and pets from unnecessary chemical exposure or recurring infestations. With Catseye, every service follows strict safety standards and includes long-term prevention strategies, giving you lasting peace of mind.

One of my favorite insects decked out in Halloween colors of black, orange, and white is the shaggy tussock moth caterpillar, which dines on members of the milkweed plant family. Every time I see one, it reminds me of the irascible creature Cousin Itt, of Adam’s Family fame. Hordes of these leaf-munchers are often seen in late summer and autumn consuming leaves of milkweeds. These caterpillars are the offspring of a species of moth known as the milkweed tussock moth or milkweed tiger moth. To understand why they present a scary meal to would-be predators, let’s review a little bit of the biology of milkweed plants and milkweed-feeding caterpillars.

Milkweed gets its name from the sticky white sap exuded from stems or leaves when their surface is broken by hungry insects or curious humans. Milky sap and cells within the leaves contain nasty chemicals called cardiac glycosides. As the name implies, these compounds have something to do with the heart. At higher concentrations, cardiac glycosides can be heart poisons, bringing death to animals like horses that eat the plants containing them. However, many insects that eat milkweeds have evolved mechanisms to deal with these toxins and have the ability to consume leaves of milkweed without being poisoned. In fact, they obtain cardiac glycosides from their food and then store these noxious compounds in their bodies. Caterpillars of both the monarch butterfly and milkweed tussock moth obtain cardiac glycosides and retain them as they develop into a butterfly or moth, respectively.

Milkweed tussock moth caterpillars devour leaves of milkweeds. As they feed, toxic cardiac glycosides found in milkweeds are ingested and stored in their bodies. Caterpillars become a noxious meal. Their orange and black coloration warns predators not to mess with them.

What is all of this chemical chicanery about? Birds are important predators of many kinds of insects,  including caterpillars and butterflies. Scientists discovered that cardiac glycosides found in monarch butterflies caused predators such as blue jays to vomit dramatically following an attempted monarch meal. Blue jays exposed to monarchs soon learned to recognize the monarch by sight and avoided eating these beautiful, but nasty tasting butterflies. Many of the insects that live on milkweed and consume its leaves display vivid patterns of orange and black as both juveniles and adults. This convergence on a similar, easily recognizable color pattern by two or more nasty-tasting insects is called Müllerian mimicry. Other milkweed feeders that participate in the milkweed mimicry ring include milkweed longhorned beetles, milkweed bugs, and milkweed leaf beetles we met in previous episodes. Like the larvae of the monarch, caterpillars of the milkweed tussock moth obtain cardiac glycosides from milkweeds and retain them as adults.

While the caterpillars of this tiger moth boldly wear the characteristic warning colors of orange and black as they feed during the day, the adult moth is comparatively drab at first glance, with pale brown wings. Nevertheless, its impressive abdomen sports the Halloween colors orange and black. The fact that caterpillars of the milkweed tussock moth store cardiac glycosides for use as adults is somewhat perplexing. Primary predators of these night-flying moths are fearsome bats that hunt using sound rather than sight to locate prey. Orange and black coloration may have little value in defeating these night-hunting predators. However, the cardiac glycosides stored in the body of the moth are put to good use. The resourceful milkweed tiger moth evolved an organ that emits an ultrasonic signal easily detected by bats. The signal warns that an attack will be rewarded with a noxious distasteful meal and bats soon learn to avoid tussock moths as prey. For many bugs in orange and black there are no treats for hungry predators.

One of my favorite late summer and early autumn bloomers is spotted horse mint, Monarda punctata. During this season horsemint attracts an amazing variety of pollinators, including several species of remarkable wasps including  great black wasps, mason wasps, and potter wasps. Among the most interesting and beautiful of these visitors are thread-waisted wasps in the family Sphecidae. One of the most common members of the sphecid clan visiting horsemint is Eremnophila aureonotata, hunter of caterpillars. Caterpillars serve as food for her larvae. Locating and subduing caterpillars requires loads of energy, and frequent trips to flowers for carbohydrate-rich nectar are regular daily activities. When not feeding on flowers, Eremnophila search foliage to find caterpillars, the food for their young. Upon finding a potential victim such as a prominent caterpillar, the female wasp wrestles with the larva and delivers a paralyzing sting. The immobilized victim is then transported to a subterranean nursery and placed beneath the ground. An egg deposited on the hapless victim hatches into a legless larva that consumes the living but powerless prey. Before leaving her young, the mother carefully arranges debris, pebbles, and dirt over the burrow to disguise the entry to her nest. This probably keeps other insects from making a meal of her young or their provisions of caterpillars.  

Mating behaviors of Eremnophila include prolonged coupling of the blissful pair with the male grasping his mate by the neck as she saunters from blossom to blossom. This prolonged tandem linkage likely ensures that the sperm of the lucky suitor will be the ones that fertilize eggs carried by his mate, sort of a behavioral guarantee of paternity. This prolonged copulatory guarding is seen in many other species of insects, such as dragonflies and damselflies. In addition to spotted horsemint, thread-waisted wasps frequent goldenrods and other members of the aster family. When your late summer and early autumn rambles take you to the meadow, try to catch a glimpse of these clever hunters as they fly in tandem amongst the blossoms.    

Spotted horse mint is a dynamite attractor of many kinds of pollinators. Watch as this female thread-waisted wasp searches blossoms for carbohydrate-rich nectar. Nectar powers her mission to find caterpillars that will be stung, paralyzed, and consumed by her offspring as they develop in subterranean galleries. Her piggy-backing mate isn’t just there for the ride. Prolonged copulation ensures that his sperm will be the ones to fertilize eggs of his mate, a behavioral insurance policy of paternity. But I wonder, does he really have to grab her by the neck?

Several members of the moth family called the Sphingidae are known as sphinx moths owing to the defensive behavior of larvae which rear upright presenting a visage reminiscent of the lion-headed Great Sphinx of Gaza. Often accompanying this display is a vomitous regurgitation of partially digested catalpa leaves meant to deter would be predators. This performance certainly would deter me from eating one.

The female sphinx moth lays batches of eggs often numbering in the hundreds on the leaves of both northern and southern catalpa trees. After hatching, larvae feed gregariously for the first several instars of their life before feeding singularly in their latter stages. Fully developed larvae wander from the plant to the soil where they form a pupa. Two or three generations are present annually throughout the range of the moth and winter is spent as a pupa in the soil near its catalpa host. Under ideal conditions for survival of adults and larvae, large populations may defoliate portions of catalpa trees.

Catalpa trees are host to the larvae of the catalpa sphinx moth. These larvae are one of the largest and most striking of all caterpillars in North America. Early stages are a chummy lot and feed gregariously. Their feeding generates waste called frass that piles up on leaves and the ground below. Watch as this one nibbles off the tip of a leaf. Ah, but like other sphinx moth caterpillars they are attacked by small parasitoid Cotesia wasps. After completing development inside the caterpillar, wasp larvae emerge through the caterpillar’s skin and spin small silken cocoons on the caterpillar’s surface. You may have seen Cotesia cocoons on a hornworm caterpillar on your tomatoes. Parasitoids like this make me glad I’m not a caterpillar.   

As with many caterpillars and other herbivorous insects, when populations become locally dense, natural enemies often arrive to take advantage of the bounty of fresh meat. A small parasitoid braconid wasp, Cotesia congregata, attacks and kills larvae of several species of caterpillars including tobacco and tomato hornworms in addition to those of the catalpa sphinx. We met clever Cotesia parasitoids attacking larvae of saddleback caterpillars in a previous episode. Check out that episode to see these alien-like creatures emerging from the skin of their host – truly creepy. Another moniker for caterpillars in the family Sphingidae is horn worm. One legend has it that the prodigious horn on its rear end is poisonous. Well, I tempted fate with one of the large catalpa sphinx caterpillars and found the horn to be rather tickly but certainly not capable of delivering any type of venom.

The last two episodes focused on the Yin and Yang of yellowjacket wasps. Well, with delightful autumn weather upon us, with fall festivals, picnics, and tailgates in full swing, it is time to visit an episode from a few years ago to avoid some nasty surprises brought to you by stinging insects. So, here is a throw-back to 2021 to help you avoid some pain.

If this episode of Bug of the Week reads like a public service announcement, well, that’s because it is. While our usual episodes demystify insects and revel in their curious and marvelous behaviors, every now and then something a bit unseemly pops up and warrants attention. In past episodes we have quelled fears of murder hornet invasions in the DMV, provided information to thwart mosquitoes and ticks, and addressed autumnal invasions of stink bugs, spiders, and other creepy creatures. This week we aim to help you avoid a nasty surprise at your October picnic.

On a recent outing to a park, my granddaughter was frightened when yellowjackets swarmed her blueberry flavored shave ice. A second unnerving tale arose when a colleague took a swig from a soda can and imbibed a yellowjacket. Fortunately, the angry vespid stung her tongue, not her throat, prior to ejection from her mouth. Lucky her, to only suffer a swollen tongue and not a life-threatening occlusion of the throat. Yellowjackets are among the most aggressive of all stinging insects in the DMV. During late summer and early autumn yellowjackets operate at a fevered pitch as workers try to gather food to maximize the production of brood back at the nest. Unlike the nests of honey bees, yellowjacket nests contain no honey or pollen. These rascals are meat eaters that also gain carbohydrates from fruits, flowers, and sometimes human-made sources. At sunny October picnics and tailgating parties, yellowjackets visit plates and battle you for bites of barbecued chicken. Meaty protein will be taken back to the hive for the developing brood. Yellowjacket larvae are fed meat and carbohydrate rich foods provided by the workers. Natural prey items of yellowjackets are other insects such as caterpillars and beetles that plague garden and landscape plants. In this regard, yellowjackets are highly beneficial.

October is a month when stinging insects hunt for food. In the wild, caterpillars are a regular source of protein, and carbohydrate rich honeydew supplies energy for yellowjacket workers and brood. Human-made sources like peanut butter and jelly sandwiches are on the menu and sweet soft drinks are favorite sources of sugar. Soda cans may contain nasty surprises, wasps or bees, so be careful and consider pouring drinks into cups. Open cups provide a chance to look before you sip. For children, consider using cups with reusable straws and tight-fitting lids for soft drinks.

By late summer and early autumn, colonies may contain thousands of workers and their subterranean or aerial nests can attain the size of a football. Under extraordinary circumstances, nests may persist for more than one year and become enormous. There are reports of monster yellowjacket nests in southern states reaching the size of a “Volkswagen Beetle”. In late summer, back in the nest, the yellowjacket assembly line switches from production of workers to the production of queens and drones. Foraging occurs at a frenetic pace. Queens produced in autumn leave the nest and seek protected locations under tree bark or in other outdoor refuges to escape the ravages of winter before founding new colonies next spring. You can learn a bit more about yellowjackets in a previous episode entitled “Be careful around yellowjackets: Eastern yellowjackets, Vespula maculifrons”. Bumble bees, carpenter bees, and honey bees are also on the prowl for sugar sources during the waning days of autumn. In addition to natural sugar sources, sweet soft drinks are also on the menu. Liquid sugar sources are guzzled and stored in the bee’s specialized honey stomach. Carbohydrate rich liquids are fed to brood, other bees, or turned into honey upon returning to the hive.

 

 

What can you do to avoid confrontations with these stingers? Choose picnic and tailgating spots carefully. Do not set up your picnic near a trash container or dumpster where yellowjackets and bees may be foraging for discarded barbeque or half-full cups of cans of sugary soft drinks. Bring a covered container to stow your trash and to keep hungry foragers away from food scraps and partially filled drink containers. Keep food covered. This reduces recruitment by foragers that accumulate around accessible food sources. Drink from clear bottles or pour drinks into clear cups. This will allow you to observe stinging insects doing a backstroke in your drink before you down them. Bees and yellowjackets often find their way into pop-top cans and can disappear down your gullet without being seen. Instead of canned drinks, try juices in drink boxes equipped with tight fitting straws. These are great for children who often place canned soft drinks down for a while before returning to finish them. Better yet, for your youngsters, pour soft-drinks into one of those cleverly designed drink containers with tight fitting lids and reusable sippy straws (good for the environment too!). If yellowjackets try to sneak a bite of your food, gently brush them away rather than engaging in hysterical slapping and squealing. Quick movements and non-lethal blows can incite painful stings. Oh, and you may have heard that yellowjackets are capable of multiple stings. This is only partially true. Contrary to common belief, some yellowjackets have barbed stingers like our friends the honey bees. Yellowjackets may lose their stingers and be eviscerated in the process. If you are stung, apply ice to the site of the sting to reduce swelling and pain. If you are stung and experience symptoms such as shortness of breath, difficulty breathing or swallowing, hives on your body, disorientation, lightheadedness or other unusual symptoms, seek medical attention immediately. Enjoy outdoor feasts with friends and families on these glorious October days. By taking a few precautions you can avoid nasty surprises from yellowjackets and busy bees.
