Local pest control in Foristell

Your Foristell exterminator, close to home

Foristell sits along I-70 right where St. Charles County meets Warren County. Many properties here have a few acres, a pole barn or workshop, and plenty of tree line. That rural setting brings a different set of pest problems than suburban neighborhoods: rodents in outbuildings, wasps in barn rafters and ticks along every field edge.

Our New Melle area office puts McCarthy technicians close to Foristell, so you get the same responsive, guaranteed service that suburban customers expect, even out on a gravel road.

We serve homes and businesses throughout Foristell (ZIP 63348) with residential pest control, commercial service and termite protection, all backed by our free re-treatment guarantee.

What we see most

Common pests in Foristell homes and businesses

Mice and rats

Barns, feed storage and workshops attract rodents year-round. Without control they move from outbuildings into the house each fall.

Wasps and hornets

Open barn eaves, equipment sheds and porches give paper wasps and bald-faced hornets protected places to build big nests.

Ticks

Field edges, tree lines and tall grass along property borders carry heavy tick populations from spring through fall.

Spiders

Brown recluse and wolf spiders shelter in outbuildings, woodpiles and basements on rural properties.
