Pest control across St. Clair County, from the river towns to the farm towns
St. Clair County is where our trucks start every morning. From the Main Street office in Belleville, the county seat, we cover the older river towns to the west, the suburbs along I-64, and the farm towns out toward Mascoutah and Lebanon, with the same perimeter-first approach on every street.

Yes. St. Clair County is our home county, and we cover all of it: Belleville, O'Fallon, Fairview Heights, Swansea, Shiloh, Mascoutah, Lebanon, Freeburg, Millstadt, Smithton, Cahokia Heights and the communities between them. Most addresses get same-day or next-day scheduling, and the phone is answered around the clock.
The local picture
One county, three kinds of pest problem
St. Clair County runs from Mississippi floodplain to rolling cropland in about thirty miles, and the pest pressure changes with the ground. The older river-side communities carry century-old housing, shared walls and aging sewers, which means rodents and roaches. The I-64 suburbs bring newer construction, heavy landscaping and retention ponds, which means ants, spiders and mosquitoes. The farm towns to the east add field-edge mice every fall and the wildlife that lives along the creek lines.
Across all of it runs the same subterranean termite pressure. The county sits in a zone rated moderate to heavy, swarm season runs March through May, and our inspection schedule fills up every spring for a reason. The brown recluse is native here too, living indoors and out across the southern third of Illinois, so spider calls in this county start with a photo rather than a guess.
What we treat most here
The calls St. Clair County makes most often
Termite Inspection
Moderate-to-heavy termite zone countywide; spring swarms send the first wave of calls.
Brown Recluse Control
Native across the county; confirmed populations need the monitor-and-void program.
Rodent Control
Fall field-edge mice in the east, alley rats in the older west-side towns.
Ant Control
Odorous house ants in kitchens from Belleville to O'Fallon every spring.
Mosquito Control
Floodplain and retention-pond breeding keeps summer evenings busy.
Wasp & Hornet Removal
Deep eaves on older homes and new soffits alike host summer nests.

What sets St. Clair County apart
Belleville, the county seat, anchors a county of roughly 270,000 people, and its housing alone tells the pest story: a median build year of 1962, more than a quarter of homes from before 1940, and a historic district of about 700 properties. Scott Air Force Base just east of Belleville keeps the I-64 corridor growing and the moving boxes rolling, which matters for hitchhiking pests like German roaches and bed bugs. Meanwhile the termite zone, the recluse range and the humid summers apply countywide, so a pest plan that works here has to cover all three.
