Bed Bug Control in Chicago, Illinois
Bed bugs move between units through shared walls, pipes, hallways and laundry rooms, and Chicago has plenty of all four. This page explains the warning signs, how a professional treatment works, what the city's bed bug ordinance expects from tenants and landlords, and how to prepare your home before a technician arrives.
Why bed bugs are so common in Chicago
Orkin's 2026 ranking of U.S. metros by bed bug treatments put Chicago in first place again (Orkin press release). That is one company's treatment data, not a citywide count, but it points the same way as what you would expect from the local housing:
- Shared structures. Bed bugs travel through wall voids, pipe chases, electrical conduits and hallways, so a unit in a high-rise, courtyard building or three-flat can be affected by a neighbor next door or a floor away.
- Shared laundry. Basement and hallway laundry rooms are common in older Chicago buildings, and bags of clothing or bedding carried through them can move bed bugs between units.
- High turnover. Students, renters and short-term housing mean furniture and belongings change hands often, including secondhand furniture.
- Heavy travel. Conventions, concerts and tourism keep hotels and short-term rentals busy, and bed bugs can hitchhike home in luggage.
Signs of bed bugs to look for
Bites alone are not a reliable sign. Many people do not react to them, and other insects leave similar marks. Look for physical evidence instead:
- Rust-colored or dark specks on sheets, mattress seams or the box spring (bed bug droppings)
- Pale, translucent skins shed as young bed bugs grow
- Live adults: flat, reddish-brown and about the size of an apple seed
- Small spots of blood on sheets or pillowcases
- A sweet, musty odor in heavy infestations
Check mattress seams and tags, the bed frame and headboard, seams of upholstered furniture, baseboards, and behind outlet covers and picture frames. If you find a suspect insect, seal it in a bag or stick it to clear tape so a technician can identify it.
Chicago's bed bug ordinance: what tenants and landlords should know
Chicago passed a bed bug ordinance in 2013 that makes landlords and tenants share responsibility for preventing and controlling infestations. According to the Chicago Department of Public Health (CDPH):
- Landlords must give tenants the CDPH bed bug information brochure when a lease is signed or renewed.
- Tenants must notify their landlord within 5 days of suspecting an infestation.
- Tenants must allow access for inspection and treatment, complete the preparation they are given, and not interfere with the work.
- Items that cannot be treated or cleaned must be disposed of, and belongings moved through common areas must be enclosed in plastic bags.
Some housing is exempt, and who pays can depend on your lease and situation. Read the CDPH bed bug brochure and ask a tenant organization or attorney if you are unsure. This is general information, not legal advice.
How treatment works
- Inspection. The technician confirms whether the problem is bed bugs and finds where they are hiding: sleeping and resting areas first, then adjoining rooms. In a multi-unit building, the units next door, above and below matter too, because treating one apartment alone often fails.
- Preparation. You receive a written checklist for laundering, bagging and clearing clutter so the technician can reach seams, baseboards and furniture frames.
- Treatment. The approach depends on the size of the infestation and the type of building. It may combine heat or steam, targeted product applications in cracks and crevices, and mattress and box spring encasements.
- Follow-up. Bed bug eggs can survive some treatments and hatch later, so a follow-up inspection is a standard part of the job. One visit rarely settles a real infestation.
How to prepare your Chicago home before treatment
Your technician will give you specific instructions. These steps apply to most jobs:
- Wash bedding, curtains and clothing, then dry them on high heat. Once dry, seal them in clean bags.
- Clear clutter around beds and couches so the technician can reach seams and baseboards.
- Bag items before carrying them through hallways, stairwells or shared laundry rooms.
- Keep sleeping in your own bed. Moving to the couch or another room can spread bed bugs.
- Skip store-bought foggers. They can push bed bugs deeper into walls and other rooms.
- Ask before throwing anything out. Chicago has rules for disposing of infested furniture and bedding, and a treatable mattress is often worth keeping.
- If you rent, tell your landlord or property manager in writing.
Bed bugs in Chicago: common questions
How do I know it is bed bugs and not another pest?
Look for droppings, shed skins and live insects along mattress seams and furniture, not just bites. Bites alone can look like many other things. An inspection confirms it, and a sealed sample of the insect helps.
Do I have to throw out my mattress?
Usually not. Mattresses and box springs can often be treated and covered with encasements. Disposal is for items that cannot be treated or cleaned, and Chicago has specific rules for how to dispose of them, so ask your technician first.
How long does it take to get rid of bed bugs?
It depends on how far the infestation has spread and how well the preparation is done. Expect more than one visit over several weeks, and be cautious of anyone who promises a guaranteed single-visit fix.
Can bed bugs spread to my neighbors?
Yes. They move through walls, pipes, hallways and on belongings, which is why buildings with several units often need a coordinated plan. Tell your landlord or property manager promptly.
Who is responsible for treatment if I rent?
Chicago's ordinance splits duties between landlords and tenants, and tenants must notify the landlord within 5 days of suspecting bed bugs. Who pays can depend on your lease and circumstances, so check the CDPH brochure above and get advice if you are unsure.
How much does bed bug treatment cost?
Cost depends on the size of the space, how widespread the infestation is, and the treatment method. Call (937) 809-8658 or email contact@ecopestcontrols.com for a quote.
