Mouse and Rodent Control in Glen Ellyn, IL
Droppings behind the stove since the first frost, scratching in the walls at night. Call (630) 000-0000 and say where you see the signs. A local exterminator finds how the mice get in, removes them and seals the gaps, and quotes before the work starts.
House mice move into Glen Ellyn homes in October, when the nights drop below freezing, and they stay until spring if nothing stops them. Older homes with fieldstone or block foundations, window wells and gaps around utility lines let them in with little effort.
A mouse fits through a gap the size of a dime. They come in along the sill plate, around pipes and wires, under garage doors and through gaps where siding meets the foundation. Once inside they live in wall voids, behind kitchen cabinets and in basement storage. Norway rats are less common in houses but show up near alleys, restaurants and dumpsters downtown and in buildings near the train tracks.
Mice, rats or something else
| Animal | Signs | Where | What it needs |
|---|---|---|---|
| House mouse | Small droppings, scratching at night | Kitchens, walls, basements | Trapping and sealing the gaps |
| Deer mouse | White belly and feet, droppings in stored items | Garages, sheds, homes near preserves | Trapping, sealing and careful cleanup |
| Norway rat | Large droppings, burrows along foundations | Alleys, garages, downtown buildings | Trapping, stations and sealing low openings |
| Squirrel or chipmunk | Running in the attic early and late in the day | Attics, soffits, under patios | A wildlife company |
Knowing which animal it is matters, because the gaps, the traps and the follow-up all depend on it. Squirrels, raccoons and bats are wildlife and are not handled here.

Where mice get into Glen Ellyn houses
The garage door and the garage-to-house wall
A worn bottom seal on the garage door, a gap at the corner of the door frame and the joint where the garage meets the house are the most common ways in. Once inside the garage, mice follow pipes and wires into the house.
Utility lines and dryer vents
Gas lines, air conditioning lines, cable and phone wires and dryer vents all pass through the foundation or the siding. The gap around each one is often wider than a mouse needs.
Window wells and fieldstone foundations
Older Glen Ellyn homes have fieldstone or block foundations with mortar gaps, and window wells that pull away from the brick over time. Both let mice in at the basement level.
The sill plate and siding
Where the wooden sill plate sits on the foundation, and where siding meets the masonry, small gaps run the length of the house.
How rodent control is done
- 01
Inspect the outside
The foundation, sill plate, window wells, utility entries, garage door seals, vents and the roof line.
- 02
Remove the mice inside
Traps are set along runways and checked on return visits until activity stops.
- 03
Seal the way in
Gaps are closed with materials rodents cannot chew through.
- 04
Exterior stations where needed
Locked stations along the outside walls for homes near preserves, fields or alleys.
- 05
Confirm it is over
Return visits continue until there is no new activity.
Sealing is what ends a mouse problem. Trapping without exclusion means a new set of mice every fall.
What is used to seal the gaps
| Gap | Material | Why |
|---|---|---|
| Around pipes and wires | Copper or steel mesh and sealant | Mice chew through foam and caulk alone |
| Garage door corners | A rodent-proof corner seal or new bottom seal | The most common way in |
| Dryer and exhaust vents | A metal vent cover with a damper | Keeps airflow and stops mice |
| Fieldstone and block gaps | Mortar or a masonry sealant with mesh | Holds up on old foundations |
Rats near alleys and downtown
Norway rats are less common in houses, but they show up near the alleys, restaurants and dumpsters downtown, near the train tracks and in buildings with older basements. They burrow along foundations and under sheds and patios. Rat work uses larger traps, locked stations and sealing of low openings. For restaurants and apartment buildings, commercial pest control covers the building as a whole.
Cleaning up safely
- Do not sweep or vacuum droppings dry That puts dust in the air.
- Wet them first With a disinfectant or a bleach solution, then wipe up with gloves on.
- Bag the waste And wash your hands afterwards.
- Leave heavy contamination to a professional Especially in insulation, attics or sheds where deer mice have nested.
What changes the price of rodent control
- The number of entry points And how high they are.
- The size and age of the house Fieldstone foundations have more gaps.
- Exterior stations Whether they are needed near preserves or alleys.
- Return visits How many it takes until activity stops.
You hear the price before the work. Every other service is on pest control in Glen Ellyn.

Rodent control questions
How long until the mice are gone?
Usually one to three weeks once the gaps are sealed and the traps are working. Return visits continue until there is no new activity.
Are poison baits used inside the house?
Inside, traps are used, so mice do not die in the walls. Locked bait stations are used outside where needed.
Is that a mouse or a squirrel in the attic?
Mice are active at night. Squirrels run in the attic early in the morning and late afternoon. Squirrels need a wildlife company.
Why do mice keep coming back every fall?
The gaps they use have not been sealed. Sealing is what ends it.
Is mouse work part of general pest control?
No. Rodent control is its own service, because sealing the gaps and the return visits are what end it.
Good boundaries. Better living.
