Pest Control in Des Moines, IA

Des Moines has a true four-season climate. July is the warmest month, with average highs near 86 degrees, and January is the coldest, with average lows around 14. The area receives about 37 inches of precipitation in a typical year and roughly 36 inches of snow, and June is the wettest month at about 5.3 inches. Around 22 days a year reach 90 degrees or higher. These are 1991-2020 NOAA climate normals from a nearby weather station, so treat them as a guide, not a forecast.

That wet June matters for pest control. Rain leaves water in gutters, birdbaths, buckets and low spots in the yard, and mosquito control works best when those breeding sites are dealt with before the hot days arrive. The same moisture soaks mulch and wood near foundations, which is exactly where carpenter ants and termites like to settle.

Then comes the other end of the year. With 128 freezing nights, mice and rats start testing garages, crawl spaces and attic vents as soon as the first cold snaps arrive, so sealing gaps in late summer and early fall is worth the effort. Winter is also a good time to check basements and storage areas for droppings, gnaw marks and nesting material, since activity indoors can go unnoticed for weeks.
