Call. URL: https://illinoispestcontrol.us/bed-bug-treatment/ Illinois Pest Control is an independent referral service that connects Illinois homeowners, renters, and property managers with participating providers for **bed bug treatment**. Bed bug service can vary by provider and location, so confirm it when you're connected. ## Signs of bed bugs The [Illinois Department of Public Health](https://dph.illinois.gov/topics-services/environmental-health-protection/structural-pest-control/bed-bugs) lists these signs: - Blood smears and dark fecal specks on sheets, mattress seams, and box springs. - Amber-colored shed skins. - A musty, sweet odor in heavy infestations. - Bites alone aren't proof; many things cause bites, and people react differently. ## How bed bugs spread IDPH says bed bugs hitchhike in luggage and on public transportation, and in secondhand furniture, mattresses, bedding, and clothing. In apartment buildings, infestations spread between units without proper treatment. That's why moving infested furniture to another room, or sleeping on the couch, often spreads the problem. IDPH also notes that while pathogens have been found in bed bugs, they apparently don't transmit diseases to people. The harm is bites, stress, and lost sleep. ## What you can do now IDPH's practical steps: - Wash bedding and clothing and dry it on high heat; IDPH says 20 or more minutes in a hot dryer kills all life stages. - Encase the mattress and box spring; IDPH says encasements are often better than treating or throwing them away. - Pull the bed away from the wall and keep bedding off the floor. - Don't move furniture or belongings to other rooms or homes. ## What professional bed bug treatment involves IDPH says that for most infestations, hiring an experienced pest management professional is preferable to doing it yourself. Treatment usually starts with an inspection to confirm bed bugs and find every affected area, then heat treatment, targeted insecticide applications, or a combination, with preparation steps for you and one or more follow-up visits. Ask the provider for their prep list and follow-up schedule in writing. ## Renters and landlords IDPH's FAQ says its Structural Pest Control Program has no authority to hold a landlord accountable for bed bugs. If you rent and your landlord won't address them, IDPH says to contact your local health department, city hall, or building code office. Report bed bugs to your landlord in writing, and check your lease and local ordinances. ## When to call about bed bugs - You've found a live bug, shed skins, or specks on bedding or mattress seams. - Bites keep appearing after you've washed and dried bedding hot. - You live in an apartment and a neighbor has bed bugs. - You brought home secondhand furniture and are seeing signs. - You manage a rental, hotel, or dorm property. ## What bed bug treatment costs HomeAdvisor's June 2026 data puts bed bug treatment at an average of **$2,500**, with most between **$1,000 and $4,000** and severe whole-home cases up to $6,200.

Heat treatment runs $1 to $3 per square foot and chemical treatment $2 to $5 per square foot. **Do bed bugs spread disease?** The Illinois Department of Public Health says that while pathogens have been found in bed bugs, they apparently don't transmit diseases to humans. Bites, itching, and lost sleep are the main harms. **Are landlords responsible for bed bugs in Illinois?** IDPH says its pest control program can't hold landlords accountable and directs tenants to their local health department, city hall, or building code office. Responsibility depends on local ordinances and your lease; report the problem to your landlord in writing. **Can I get rid of bed bugs myself?** IDPH says hiring an experienced pest management professional is preferable for most infestations. Washing and drying bedding hot and using encasements help, but they rarely solve an established infestation alone. **Does heat kill bed bugs?** Yes.
