What To Know About Pests In Illinois

Illinois swings hard between hot, humid summers and cold, snowy winters, and pests have figured out how to ride out both. Summer is peak season: mosquitoes breed in standing water, wasps build nests, and ants pour inside hunting food.

Then the cold hits and everything changes direction, heading indoors for warmth. Rodents are the big winter problem here, squeezing through gaps to nest in walls and attics, and overwintering bugs like boxelder bugs, Asian lady beetles, and stink bugs pile in right alongside them.

When Pests Are Most Active In Illinois

Spring
Termite swarms and ant trails. Carpenter ants wake up in damp wood around windows and decks.
Summer
Mosquito season, especially after storms. Yellow jackets and paper wasps build nests.
Fall
Mice move in as soon as nights get cold. Boxelder bugs and Asian lady beetles cluster on sunny walls.
Winter
Rodents nest in walls and basements. Roaches and bed bugs stay active in heated buildings.

Common Pests In Illinois

Hot summers and freezing winters mean two different pest seasons in Illinois. Here’s what shows up across the state.

Illinois Pest Control FAQs

Can’t find your answer? Send us a message.

What’s a fair price for pest control in Illinois?

Expect $300 to $550 for a one-time general visit, based on Angi’s national range. Rodent exclusion, where they seal every entry point, usually costs more but saves repeat calls.

Chicago prices tend to run a bit higher than downstate. Get a quote that lists exactly what’s being sealed.

Why does Chicago have so many rats?

Dense housing, alleys full of trash carts and old sewers give Norway rats food and shelter. Chicago held No. 1 on Orkin’s Rattiest Cities list for a decade and is now No. 2 behind Los Angeles.

Keep garbage in sealed carts and report rat burrows to 311. The city runs its own rat baiting program.

How do I keep mice out in winter?

Seal gaps around pipes, vents and the garage door before October. A mouse fits through a gap the size of a dime.

Steel wool and caulk work for small holes. Bigger gaps need metal flashing or hardware cloth.

What are the bugs all over my house in fall?

Usually boxelder bugs or Asian lady beetles. They gather on warm, sunny walls looking for a place to spend the winter.

They don’t bite or damage the house much, but they get inside walls. Seal gaps early and vacuum the ones that get in.

My apartment has bed bugs. Who pays?

In Chicago, landlords are responsible for treating bed bugs in most cases, and they have to give tenants information about them.

Report it in writing and let them inspect neighboring units too.

Are pest treatments safe for children and pets?

Yes. Licensed techs use products approved for homes. Keep everyone off treated areas until they dry.

Rodent bait stations are locked and placed out of reach of kids and pets.

Can I handle a mouse problem myself?

One or two mice, sure. Snap traps along walls work well.

If you keep catching them, there’s a gap you haven’t found. That’s when exclusion work pays off.
