Typical prices, not quotes
Rodent job costs in Chicago swing a lot depending on whether it's just trapping or a full seal-up job. Here's the typical range.
| Job | Low | High | What moves it | Scope |
|---|---|---|---|---|
| Trapping only, light activity | $350 | $500 | number of traps and follow-up visits | interior trapping, one or two return trips |
| Trapping plus partial exclusion | $500 | $750 | number of entry points found and sealed | trapping plus sealing a handful of gaps |
| Full exclusion with attic or crawl space work | $750 | $1,000 | attic cleanup, insulation, and full perimeter sealing | whole-house entry sealing plus cleanup |
Real cost depends on how many entry points a two-flat or bungalow actually has. Old brick buildings often need more sealing than newer construction.

Local conditions that shape the work
Here's the thing about Chicago and rodents: the housing stock basically invites them in. Much of the city is old brick two-flats, three-flats, greystones, and workers cottages built from the 1870s rebuild through the bungalow boom of the 1910s to 1930s. All that masonry has utility penetrations, foundation gaps, and aging mortar joints that mice and rats treat like a welcome mat. I've crawled into basements in Bridgeport and Bronzeville where you could see daylight around an old sewer pipe entry. That's a mouse highway.
Add in the alley garbage corridors running behind most Chicago blocks, and you've got a steady food source pulling rats toward buildings anyway. September through November is when it gets bad. That's when Norway rats and house mice start pushing indoors ahead of the cold. Chicago winters are long, the ground freezes hard, and once a rodent finds a warm gap in a masonry foundation, it's not leaving voluntarily.
Under the Chicago Health Code, property owners are on the hook for keeping buildings free of rodents. Landlords generally carry that responsibility in rental units under the city's landlord-tenant ordinance. Real talk: waiting it out isn't really an option if you're renting units out. Full or partial basements with poured concrete, block, or older rubble stone foundations are the norm here, and those older foundations are exactly where exclusion work matters most.
From your call to a written quote
- Call and describe what you're hearing or seeing
Scratching at night, droppings, gnaw marks. The provider uses this to figure out if it's mice, rats, or something bigger before they even arrive.
- Inspection and a written quote
The provider walks the basement, attic, and foundation perimeter to find entry points, then gives a price before any work starts.
- Trapping and sealing
Traps go in first if there's active activity, then entry points get sealed with the right materials for brick, block, or wood-frame construction.
- Follow-up check
A return visit confirms the traps are clear and the seal job is holding, especially heading into the colder months.
Good to know
How much does rodent control cost in Chicago?
Typical jobs run $350 to $1,000 depending on whether it's just trapping or full exclusion work. Trapping alone with light activity lands near the low end. Sealing an old brick foundation with attic cleanup pushes toward $1,000. The provider quotes the exact price after seeing the building.
Why do Chicago basements get mice every fall?
Norway rats and house mice push indoors from September through November as temperatures drop, and older Chicago foundations, brick two-flats, and bungalows have plenty of small gaps around utility lines and aging mortar. Once they find a warm entry point, they don't leave on their own.
Is the landlord responsible for rodent control in Chicago rentals?
Generally, yes. Under the Chicago Residential Landlord and Tenant Ordinance, landlords typically carry responsibility for pest control in rental units, and the Chicago Health Code requires property owners to keep buildings free of rodents and vermin. Check your lease for specifics.
Does rodent control include sealing entry points, or just traps?
Depends on what you ask for. Some jobs are trapping only, aimed at clearing an active population fast. Full exclusion adds sealing every entry point around the foundation, which costs more upfront but is what actually keeps rodents from coming back next fall.
How fast can someone come out for a rodent problem in Chicago?
Call and describe what's going on: droppings, scratching, gnaw marks. The provider will tell you their earliest opening. Rodent issues are usually treated as urgent, since droppings and gnawed wiring are food safety and fire risks, so most providers try to move fast.
