O'FALLON FAQ

O'Fallon pest control questions.

How much is pest control in O'Fallon?
Most O'Fallon homes start at $45 a month for quarterly Home Shield, with a first visit from $150 after the $100 new-customer discount. Bigger homes and lots can cost a bit more. We give you the exact price by phone.
Why do new homes get so many pests?
Building on open land stirs up the mice, ants and spiders that lived there first, and fresh landscaping gives them cover. A quarterly barrier stops them at the foundation.
Do you handle mice?
Yes. Rodent Guard puts locked bait stations outside and checks them every quarter, from $85 a quarter on its own or bundled with Home Shield.
Can you treat my yard for mosquitoes?
Yes. Mosquito & Tick treats shady resting spots and breeding areas about every 3 weeks from mid-April to mid-October, from $65 a treatment.
Do you really come out to O'Fallon?
Every week. We are based in West County, and our St. Charles County route runs through O'Fallon.
