Pest Control in Granite City, IL — Floodplain-Smart Since 1967
Granite City sits almost entirely in the American Bottom — the Mississippi floodplain — behind the levee system. That geography shapes every pest problem in town: a high water table, damp soils, drainage canals, and Horseshoe Lake a mile away. Add a housing stock built largely in the early 1900s for steelworker families, and you get a pest profile we know street by street after nearly 60 years.
Imel Pest Control is family-owned, based in Bethalto, serving Granite City with no contracts and free inspections. Voted Best of the Best 2023, 2024, and 2025.

What floodplain living means for your home
Rodents follow the water
Between the drainage canals, the rail corridors, and the industrial areas, Granite City carries steady rat and mouse pressure year-round — it’s our single most common call in town. Norway rats burrow along foundations and outbuildings near canals and tracks; mice move into the tight-set older housing blocks every fall. Our rodent program here always pairs baiting/trapping with exclusion work, because in a town with this much pressure, an unsealed home just re-infests.
Fall invaders on older frame housing
Granite City’s tight-set, early-1900s housing blocks give overwintering pests exactly what they want each October: warm south- and west-facing walls, original wood siding with gaps, and old storm windows. Boxelder bugs, Asian lady beetles, and stink bugs gather by the hundreds, then work into wall voids and attics for the winter — and reappear inside on warm days from January through spring. The effective play is a timed exterior barrier treatment in early fall, before they aggregate; once they’re inside the walls, options narrow to waiting them out.
Moisture pests in slab and crawlspace homes
The high water table keeps crawlspaces damp, which drives sowbugs, millipedes, and roaches around plumbing, and the termite moisture conditions that never really go away in the Bottom. Steelworker-era homes with additions and enclosed porches are frequent termite finds during our free inspections.
Multi-family and rental blocks
We work with Granite City landlords on roach and bed bug treatment in multi-unit buildings — problems that require treating adjoining units and follow-up visits, not just a single spray and done. Two-week follow-ups on roach work are included in our price.

Termite Treatments You Can Count On
Termites are some of the most dreaded pests around, and for good reason. These wood-eating insects can seriously jeopardize the structural integrity of your home. While it’s more common for termites to live underground and outside the home, they may find their way in for a snack if their usual sources of food have grown scant. When they feed on the frame of your home, this could pose a serious risk to you, your family, your employees, or even your customers. Be on the lookout for these common signs of termites.
Termite Infestation Symptoms
- Earth/mud-colored tubes or tunnels that lead from the ground to the home
- Solid wood that sounds weak or hollow
- Damaged wood that crumbles easily
- Buckling/warped floors, ceilings, and walls
- Presence of flying ants or termite swarmers
Rodent Control Specialists in Your Area
While termites feed on the structure of your home, rodents pose an altogether different problem for any home or business that’s unlucky enough to have an infestation. In fact, mice and rats may carry bacteria and diseases that could spread through your home. Don’t live with this threat – contact Imel for indoor and outdoor pest control treatments that aim to get rid of any rodents that have infiltrated your lair. Additionally, we use poison and bait traps that aim to cut off access points and draw out the creatures that have taken up residence at your property. Contact Imel for more details about rodent infestations and watch for the following warning signs.
Rodent Infestation Symptoms
- Noises – You might hear scratching, squeaking, or rustling. Rodents tend to be active when nobody is around, which means you could hear them moving around at night.
- Mouse/Rat Tracks – Barely visible, these might be noticeable smudge marks or dried urine stains that form a trail where rodent activity has been suspected. You may also find droppings or tracks between where droppings have been found.
- Nests/Shelter – You find a nest in a wall or around your home, or you have piles of logs or other debris up against the home that could serve as a nest.
- Rodent Droppings – Tiny brown droppings can be found where rodent activity has been observed or suspected
- Chew Marks – You find tiny chew marks on bags of food, food containers, cabinets, etc.

FAQ
Q: I see rats near my garage but not in the house — should I wait?
A: No. Exterior rats burrowing near a structure are one cold snap or one construction disturbance away from moving inside. Exterior bait stations and sealing entry points now is far cheaper than an interior infestation later.
Q: Why do I get bugs in my house every time it rains hard?
A: Granite City’s high water table means heavy rain pushes moisture pests — sowbugs, millipedes, roaches — up and out of saturated soil and drains toward the nearest dry harborage: your foundation. A perimeter treatment program timed to the wet season breaks the cycle.
Q: Can you treat just my unit for roaches in a multi-family building?
A: We can, but we’ll be honest: in attached buildings, roaches travel through shared walls and plumbing, so treating adjoining units at the same time is what actually solves it. We work with landlords to coordinate, and every roach job includes a two-week follow-up at no extra charge.
