Local pest control in St. Paul
Your St. Paul exterminator, close to home
St. Paul is a small city in St. Charles County, north of O'Fallon, where established homes sit alongside newer neighborhoods and open land. (We mean St. Paul, Missouri, not the Minnesota capital.) Homes here share the same pest pressures as the rest of the county, plus a little extra rodent and insect traffic from nearby fields and woods.
McCarthy has served St. Charles County since 1968, and St. Paul is a regular stop on our routes. We keep things simple: a thorough inspection, a clear plan and price, and free re-treatment if pests come back between scheduled visits.
We serve homes and businesses throughout St. Paul with residential pest control, commercial service and termite protection, all backed by our free re-treatment guarantee.
