Pest Control in O'Fallon, IL — New Homes Get Pests Too
O’Fallon has been one of the fastest-growing towns in the Metro East for two decades, and most of the calls we get here come from subdivisions built since the 1990s. Which surprises people — “the house is only eight years old, how do I have termites?” But new construction has its own pest logic, and after nearly 60 years in this region, we know it well.
Imel Pest Control is family-owned, serving St. Clair County since 1967, with no contracts, free inspections, and Best of the Best awards in 2023, 2024, and 2025.

Why new O'Fallon homes still get pests
Construction creates termite conditions
Grading disturbs and aerates soil; form boards and wood scraps get buried near foundations, and irrigation plus fresh sod keep the ground moist all season. Subterranean termites find slab expansion joints, plumbing penetrations, and porch/patio junctions — and a colony can feed for years before drywall damage shows. Sentricon Always Active stations around a newer home are cheap insurance compared to the repair bill; many of our O’Fallon customers add them at move-in.
Ants love new subdivisions
Odorous house ants and pavement ants thrive under new sidewalks, patios, and landscape stone. The “tiny ants in the kitchen every spring” call is our number-one service request. Store sprays scatter colonies and make it worse — baiting and perimeter treatment solve it.
Edge-of-development wildlife pressure
Subdivisions backing onto farm fields and construction sites inherit the field mice each fall, especially after harvest and after new phases break ground. If your home backs onto open land, October exclusion work is the play.
Military moves and bed bugs
With Scott AFB next door, O’Fallon sees constant relocation traffic — and moving (used furniture, storage, hotels, household-goods shipments) is how bed bugs travel. We provide inspections and treatment, and documentation if you need it for a landlord or other type of claim.

The Area’s Choice for Professional Termite Control
Termite Infestation Signs
- Buckling/warped floors, ceilings, or walls
- Earth/mud-colored tubes or tunnels that lead to the home from the ground
- Presence of flying ants or termite swarmers
- Solid wood that sounds weak or hollow
- Damaged wood that crumbles easily
As far as household pests are concerned, termites have the potential to cause the most damage to your home or business. That’s because these wood-eating insects enter your home looking for something to snack on. However, what they find is the wood frame of your home that puts the structural stability of roofs, walls, ceilings, and floors in jeopardy. Call our staff when you notice the signs of termite damage.
Professional Rodent Control Specialists
In addition to termites, rodents can have an equally unhealthy effect on your life, but in a slightly different way. Mice and rats can spread disease and bacteria that make people in your home or business very sick. Additionally, they enter the home through tiny spaces that their flexible bodies can fit through, and they’re able to build nests in HVAC ducts, walls, ceilings, attics, basements, etc. Luckily, Imel has the answers to your rodent problems, which include indoor and outdoor treatments that feature bait traps and poison. Don’t live in a home that’s full of rodents – call Imel to get rid of this scourge. Call us if you notice the following signs of a rodent infestation!
Signs of a Rodent Infestation
- Rodent Droppings – Tiny brown droppings can be found where rodent activity has been observed or suspected.
- Mouse/Rat Tracks – Barely visible, these might be noticeable smudge marks, lines of droppings, or urine marks that make trails between the areas of suspected rodent activity.
- Noises – You might hear scratching, squeaking, or rustling. Rodents tend to be active when nobody is around, which means you could hear them at night.
- Nests/Shelter – You find a nest in a wall or other hard-to-reach places around your home. Also, they may use piles of logs or other debris, up against the home, to build a nest and gain access.
- Chew marks – You find tiny chew marks on bags of food, food containers, cabinets, etc.

FAQ
Q: My house is less than 10 years old — do I really need a termite inspection?
A: Yes, and it’s free, so there’s no downside. Construction leaves buried wood debris and moist, disturbed soil — ideal colony conditions — and slab homes hide activity longer because there’s no crawlspace to spot mud tubes in. We find active termites in newer O’Fallon subdivisions every year.
Q: Why do ants keep coming back after I spray?
A: Repellent store sprays kill foragers and split the colony (“budding”), so you get more nests, not fewer. Professional baiting lets workers carry treatment back to the queen — that’s what actually ends it.
Q: Do you offer anything for homes backing up to farm fields?
A: Yes — a fall exclusion-and-baiting service timed before harvest-season mouse migration, plus perimeter treatments during the growing season for the insects field edges generate.
