Chicago Pest Control Guide for New Renters — What You Need to Know

Moving to a new apartment is exciting — until you discover bed bugs in the mattress, mice in the kitchen, or cockroaches behind the stove. Chicago's rental market moves fast, and it's easy to skip the pest inspection in the rush to sign. Here's a practical guide for new renters: what to check before you commit, your rights if pests show up later, and how Sleep Tight can help.

What to inspect before signing the lease

During your walkthrough, look beyond the fresh paint. Check mattress seams and the area behind the headboard for bed bug signs — tiny black spots, shed skins, or blood stains. Open kitchen cabinets and look under the sink for droppings or smudge marks. Turn on the bathroom light after dark and watch for cockroaches. Ask the landlord directly: has this unit had pest treatment in the last 12 months? If the answer is evasive, that's a red flag.

Under Illinois law, landlords must disclose any known bed bug history in the prior 12 months. If they don't, you may have grounds to break the lease later.

Your rights as a Chicago tenant

The Chicago Residential Landlord and Tenant Ordinance (RLTO) and the Chicago Bed Bug Ordinance give tenants strong protections. Landlords are required to maintain a habitable unit, which includes pest control. For bed bugs specifically, landlords must hire a licensed pest control professional within 10 days of receiving written notice from a tenant. The landlord pays for inspection and treatment in almost all cases.

Document everything. Email your landlord, keep copies, take photos, and save receipts for any expenses you incur. If the landlord refuses to act, you can file a complaint with 311 and may be entitled to repair-and-deduct or lease termination with proper legal guidance.

• Landlords must treat pests — it's part of the warranty of habitability
• Bed bug treatment must start within 10 days of written notice
• Landlords must disclose bed bug history from the prior 12 months
• Tenants should not be charged for standard pest treatment
• Withhold rent only after consulting a tenant rights attorney

What to do if you find pests after move-in

First, don't panic. Bed bugs, cockroaches, and mice are common in Chicago's dense rental market, and none of them reflect on your cleanliness. Second, notify your landlord in writing immediately — email is fine, but keep a copy. Third, call Sleep Tight for a free, independent inspection. Our report gives you documented evidence of what you're dealing with, which you can use in conversations with your landlord or in a formal complaint.

If your landlord refuses to treat, you have options. We regularly provide inspection reports that tenants use to support 311 complaints, and we can treat directly if your lease allows or if your landlord authorizes it.

Why this matters for Chicago homes and apartments

Chicago's pest pressure is unusual for a major American city. The combination of a 100-year-plus housing stock, dense alley-based garbage collection, lake-effect humidity from May through September, and a freeze-thaw cycle that opens new foundation cracks every winter creates year-round opportunity for pests that would be seasonal almost anywhere else. Bed bugs and German cockroaches stay active inside heated buildings through January. Norway rats expand burrow networks under garages and gangways the moment ground temperatures crack 40°F. Mosquitoes breed in any standing water within a quarter-mile radius. The result is that the same pest problem in Chicago needs a different response than the playbook a national chain runs in a Sun Belt suburb.

That is why Sleep Tight built its service model around Chicago specifically: same-day appointment availability across all 77 community areas, licensed technicians who know the difference between a Greystone basement and a four-plus-one wall void, transparent flat-rate pricing instead of national-chain upsell scripts, and aftercare that accounts for shared-wall and shared-alley re-introduction risks.

What to do if you are seeing this problem right now

First, do not start spraying over-the-counter products. Foggers, bug bombs, and most consumer aerosols scatter the population deeper into wall voids, baseboards, and adjacent units, which makes the eventual professional treatment harder and more expensive. Second, document what you are seeing — photos of the pest, the location, droppings, damage, or bites — so a technician can confirm species and severity over the phone before the visit. Third, if you rent, notify your landlord or property manager in writing the same day; Chicago's Residential Landlord and Tenant Ordinance (RLTO) protects tenants who report infestations in good faith and obligates the landlord to coordinate professional treatment in nearly every case.

• Bag bedding, soft goods, and any items near the activity in sealed plastic — do not move them to another room.
• Keep sleeping in the affected room if bed bugs are suspected; moving rooms starts a second infestation.
• For rodents, do not seal up burrows or holes before treatment — exclusion happens after the population is knocked down.
• For mosquitoes, walk the perimeter and empty every container holding standing water; even a bottle cap can breed dozens.
• Call (773) 240-5932 for a same-day inspection — most Chicago neighborhoods can be on the schedule within four hours.
