Pest Control Services In Illinois
Chicago-area rodents and Illinois winters keep mouse and rat work busy. Summer brings ants, wasps and mosquitoes.
Termite ControlEastern subterranean termites are active across Illinois, even up north. Swarms show up in April and May.
Roach ExterminationGerman roaches spread through apartment buildings. Treating one unit rarely works if the neighbors have them too.
Rodent ControlChicago has topped national lists for rat problems for years. Norway rats burrow along foundations and alleys.
Bed Bug TreatmentBed bugs move between apartments, hotels and transit. Tell your landlord early so the whole building gets checked.
Ant ControlPavement ants and carpenter ants are the common ones. Carpenter ants mean damp wood somewhere.
Wasps & HornetsYellow jackets build nests in walls and the ground. Late August is when they get aggressive.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.
Most Common Pest Calls In Illinois
AntsAnt trails along baseboards and windowsills are one of the most common calls we get in Illinois, especially as the weather warms up in spring. One trail usually leads back to a nest somewhere close by.
Bed BugsBed bugs move easily between apartments and hotels across Illinois, hiding in mattress seams and furniture. They don’t go away on their own, and DIY sprays rarely reach where they’re actually hiding.Common Pests In Illinois

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.
