Mice and Norway rats are a fact of life around St. Louis County, especially as temperatures drop in October and November. A house mouse can squeeze through a hole the diameter of a pencil; a young rat can squeeze through a half-inch gap. Older Missouri housing stock — and even newer construction with sloppy utility penetrations — has plenty of both.
Trapping alone doesn't fix a rodent problem. The trick is finding how they got in, sealing it, and then clearing whatever's already inside. That's the work. We've been doing it in Eureka, Ballwin, Wildwood, and the surrounding cities for over five decades.
