Rodent Control

Trapping, exclusion, and sealing for mice and rats, built to end the problem rather than just knock it back for a few weeks.

Rodent control gets mice and rats out of a structure and closes the gaps that let them in. It is the most common pest call Illinois operators get from October into winter, when cold weather pushes rodents toward any heated building they can reach.

Real rodent work is more than setting a few traps. Mice breed year-round once they are inside a warm house, so trapping without sealing the entry points just clears the current animals and leaves the door open for the next ones. A proper Illinois rodent program pairs trapping with exclusion: finding and sealing the gaps, since a mouse needs only a pencil-width opening and a rat needs about the width of a quarter.

What rodent control covers

  • House mice, the most common indoor rodent in Illinois
  • Norway rats, an established problem in Chicago and the inner suburbs
  • Inspection to find entry points and the conditions feeding the activity
  • Trapping programs, set and monitored rather than left in place
  • Exclusion: sealing gaps with steel and hardware cloth, not just caulk
  • Advice on the food, clutter, and harborage that draw rodents in

What to expect

  1. 1

    Inspection

    The technician finds the entry points, runways, droppings, and nesting spots, and pins down how rodents are getting in.

  2. 2

    Trapping

    Snap traps and stations go in at the active runways. The operator monitors and resets them rather than leaving them and walking away.

  3. 3

    Exclusion

    Entry points get sealed with steel wool, hardware cloth, and proper sealant. This is the step that actually ends the cycle.

  4. 4

    Follow-up

    A return visit confirms the activity has stopped and catches any gap that was missed the first time.

What it costs in Illinois

An initial rodent inspection and treatment in Illinois runs about $150 to $350 in the Chicago metro and $100 to $250 downstate. That covers the first visit and an initial round of trapping.

A full exclusion and trapping program, which includes sealing the entry points, generally runs $300 to $600 for a standard residential job. Heavy infestations that need structural exclusion work, attic cleanup, or insulation replacement can run from $500 up past $2,500. The cost is driven mostly by how many entry points need sealing and how much access and repair the building requires.

Rodent Control: common questions

Why not just use poison bait?
Bait alone has real downsides indoors: a poisoned rodent can die inside a wall and create an odor problem, and bait does nothing to close the gaps the next rodent uses. Good rodent control leans on trapping and exclusion. Bait, where it is used at all, is a supporting tool, not the whole plan.
How long does it take to get rid of mice?
A typical mouse job in an Illinois home is brought under control over a few weeks: an initial visit, monitoring, and a follow-up. Severe infestations or homes with many entry points take longer.
Will sealing the house actually keep them out?
Exclusion is the part that lasts. A mouse fits through a gap the width of a pencil, so the technician seals pipe penetrations, gaps under doors, vents, and foundation cracks. Without that step, trapping only clears the current rodents.
Why do I have mice every fall?
Across Illinois, mice move toward heated structures once outdoor temperatures drop below about 40 degrees. Downstate, the corn and soybean harvest pushes large numbers off the fields into nearby homes. If it happens every year, the house has open entry points that need sealing.
