Pests in Swansea
What we deal with most around Swansea, IL
Heat is what drives Swansea's pest picture. Ants, cockroaches and spiders are active most of the year, fleas do well in lawns and around pets, and mosquitoes multiply as soon as spring rain fills the low spots. Termites are a concern for any wood-framed home, and carpenter ants move into wood that has been softened by moisture around roofs, decks and plumbing.
There are only about 94 nights a year at or below freezing, so many insects never fully shut down for winter. Mice and rodents still look for warm gaps when it turns cold, and stink bugs and boxelder bugs gather on sunny walls in the fall. Wasps take over eaves, mailboxes and sheds in summer, so a quick walk around the yard every few weeks is time well spent.
Weather and pests
How Swansea's weather affects pest activity
Summers in Swansea run hot and winters stay on the mild side for Illinois. July highs average about 90 degrees and January lows about 24, with January the coldest month. A typical year brings about 43 inches of precipitation and 11 inches of snow, and May is the wettest month at about 5 inches. All of these are 1991-2020 NOAA climate normals from a nearby weather station, which makes them a guide, not a forecast.
The area sees about 53 days a year at 90 degrees or higher, and those hot spells accelerate everything from ant colonies to mosquito hatches. May rain leaves puddles in gutters, buckets and lawn depressions, and the moisture sinking into the ground beside a foundation is exactly what termites want. Keeping gutters clear and grading soil away from the house both help.
With a warm season this long, year-round attention beats a one-time fix. Use early spring to seal gaps and treat the exterior, summer to manage water and nests, fall to close up entry points, and winter to inspect garages and attics.

How we fix it
Pest control services in Swansea
Ant treatment in Swansea
Ants are among the most common calls we get in Swansea, from sugar ants in kitchens to carpenter ants in damp or damaged wood. Hot summers keep colonies growing all season. We find the trails and the nest, treat where the colony lives and follow up so they do not simply return.
Rodent control in Swansea
Mice and rats look for food, warmth and shelter, and Swansea buildings offer plenty of all three. With a long cold season, the pressure builds every fall. Our exclusion-based approach combines inspection, sealing entry points, trapping and monitoring, so you fix the reason rodents got in, not only the rodents you can see.
Termite control in Swansea
Termites are a quiet threat because damage often goes unnoticed for years. Regular moisture around foundations makes regular checks especially worthwhile. We inspect for mud tubes, damaged wood and moisture problems, then treat with a plan matched to how your Swansea home is built.
Cockroach control in Swansea
Cockroaches are hard to get rid of with store-bought sprays. We locate the hiding places, treat cracks, crevices and voids, and use monitoring so we know the treatment worked. It is a common request in Swansea apartments, restaurants and older homes alike.
Spider control in Swansea
Most spiders are harmless, but nobody wants webs around the door or a spider in the basement. We remove webs and egg sacs, treat the perimeter and reduce the insects that spiders feed on, which keeps them from coming back.
Mosquito control in Swansea
Swansea's wet weather makes mosquitoes a real nuisance. We treat resting areas in your yard, help you find and remove breeding sites and schedule visits through the warm season so you can use your yard again.
