Pest Control in Collinsville, IL — From the Bluff to the Bottoms
Collinsville sits right on the edge — literally. Uptown and the older neighborhoods sit on the bluff, while the west side of town drops into the American Bottom floodplain toward Fairmont City and the horseradish fields. That split is exactly why pest control here isn’t generic: bluff-top homes and bottomland properties have genuinely different problems.
Imel Pest Control has served Collinsville since 1967. Family-owned out of Bethalto, with no contracts, and voted Best of the Best in 2023, 2024, and 2025.

Two towns, two pest profiles
Up on the bluff — Uptown and the older neighborhoods
Housing here runs early-1900s frame and brick: settled foundations, original sill plates, and mature trees close to the house. The steady calls we get are subterranean termites (mud tubes in crawlspaces and basement walls), overwintering mice, and carpenter ants trailing in from big shade trees. Homes with old detached garages are a particular termite hotspot — untreated garage sills are often where a colony establishes before moving to the house.
Down in the bottoms
Lower-elevation properties toward the west side deal with high water tables and heavy summer mosquito pressure off standing water. After wet springs, displaced rodents move to higher, drier structures — sheds, garages, and homes. If your property backs onto drainage ditches or low fields, fall rodent-proofing isn’t optional; it’s the difference between a quiet winter and a January phone call.
Commercial along 157 and Collinsville Road
Restaurants, hotels near the interstate, and retail all carry inspection and reputation stakes. We provide documented commercial service —treatment records, and scheduled visits that don’t disrupt business hours.

Rodent Infestation Signs
- Chew Marks – You find tiny chew marks on bags of food, food containers, cabinets, etc.
- Noises – You might hear scratching, squeaking, or rustling. Rodents tend to be active when nobody is around, making the night a perfect time for them to look for food.
- Rodent Droppings – Tiny brown droppings can be found where mice or rats have been suspected, seen, or heard.
- Mouse/Rat Tracks – Barely visible, these might be noticeable smudge marks or dried urine stains that make trails where the activity is suspected. They might be found along walls or connecting the areas where you find droppings.
- Nests/Shelter – You find a nest in a wall or around your home, or you have piles of logs or other debris close to the home that could serve as a nest.

FAQ
Q: My detached garage has termite damage — will they spread to the house?
A: Very likely, eventually. A colony feeding on a garage is foraging outward from a nest in the surrounding soil, and your house is a bigger food source. Treating “just the garage” rarely works; Sentricon stations target the colony itself so both structures are protected.
Q: Why are mice worse some winters than others in Collinsville?
A: Wet years push rodents out of the bottoms and low fields into structures, and mast years (heavy acorn crops) boost populations. The fix is the same regardless: seal entry points before October and maintain exterior bait stations.
Q: Do I need to be home when you treat my house?
A: Not always. Exterior perimeter treatments and bait-station checks can be done while you’re at work — we just need access to the yard. Interior treatments and inspections do require someone home to let us in.
