Pest Control in Rock Hill, MO

As a guide and not a forecast, these numbers are 1991-2020 NOAA climate normals from a nearby weather station. July highs average about 90 degrees, and January lows average around 25. Rock Hill gets about 44 inches of precipitation in a typical year, and winters bring some snow (about 10 inches in a typical year). May is the wettest month, at about 4.9 inches.

The pattern looks like this in practice: a wet late spring, a hot summer, a mild fall and a winter that is chilly with some snow now and then. Rain that pools in low lawn areas becomes mosquito breeding water, so grading, clean gutters and emptied containers help. Warm, humid weather also speeds up ant colonies and cockroach populations, especially in kitchens and utility rooms.

About 79 nights a year fall at or below freezing, which is fewer than in most of Missouri, but it is still enough to make heated buildings attractive. Rodents look for a way in when temperatures drop, and they do not need much space. Sealing gaps around pipes, capping chimneys and screening vents in early fall is worth the time. Keep bird seed and pet food in sealed bins, since spilled seed draws mice and other rodents close to the house.
