Local pest control in Cottleville

Your Cottleville exterminator, close to home

Cottleville packs a lot into a small footprint: the restaurants and shops of Old Town Cottleville, St. Charles Community College, and quiet subdivisions tucked into the trees along Dardenne Creek. Homes that back up to woods and creek banks get more visits from ticks, carpenter ants and stinging insects than homes on open lots.

Because our headquarters is just down the road, Cottleville is one of our quickest service areas. We treat the wooded edges where pests start, protect foundations from termites, and help Old Town restaurants stay clean and compliant.

We serve homes and businesses throughout Cottleville (ZIP 63304) with residential pest control, commercial service and termite protection, all backed by our free re-treatment guarantee.

What we see most

Common pests in Cottleville homes and businesses

Ticks

Wooded lots and creek corridors are ideal tick habitat. Deer and small mammals carry ticks right to the edge of your lawn.

Carpenter ants

Mature trees and damp wood around decks and fascia boards attract carpenter ants, which can hollow out structural wood over time.

Yellowjackets and paper wasps

Ground nests in landscaping and wasp nests under eaves are common in Cottleville's tree-lined neighborhoods by midsummer.

Restaurant pests

Flies, cockroaches and rodents are the main concerns for Old Town Cottleville kitchens and patios. Scheduled commercial service keeps them in check.
