See all on the mapWhat to know about pest control in Illinois
Illinois stretches far enough north to south that the pests change as you drive across it. Brown recluse spiders and lone star ticks are mostly a southern Illinois concern, while blacklegged ticks are most common in the north. Knowing who licenses pest control companies in Illinois makes it easier to hire well.
Common pests in Illinois
The Illinois Department of Public Health and the Illinois Department of Natural Resources write about these pests for residents.
- Brown recluse spiders. The Department of Natural Resources says this spider lives in the southern two-thirds of Illinois, often inside houses in dark places like closets and dressers. The Department of Public Health says it should be considered rare outside that range. See our page on spiders.
- Black widow spiders. The northern black widow is the black widow most common in Illinois.
- Blacklegged ticks. These ticks are most common in northern Illinois and around river corridors, and they can spread Lyme disease. See our page on fleas and ticks.
- Lone star ticks. This tick is more common in the southern half of Illinois and can spread tularemia and other diseases.
- American dog ticks. This is the most common tick throughout Illinois. It occasionally spreads Rocky Mountain spotted fever and tularemia.
Who licenses pest control companies in Illinois
The Illinois Department of Public Health licenses structural pest control businesses and certifies the technicians who do the work. A business must employ at least one certified technician and show proof of insurance before it can get a license. Technicians become certified by passing state exams. Read more, and find the department's search for licensed pest control businesses, on its Structural Pest Control page.
How to check a company before you hire
- Confirm the company's license with the Illinois Department of Public Health, and ask whether the technician coming to your home is certified.
- Ask which pest they found and what evidence shows it. For a spider problem, ask them to identify the spider before treating.
- Ask which treatment they recommend, what the other options are, and how many follow-up visits are included.
- Get the treatment plan and any warranty in writing before work starts.
- Read reviews from other Illinois customers. If you've hired a company, you can write a review to help your neighbors, and learn how reviews work.
