Pest Control in Andover, MN

Andover has some of the coldest winters in this part of Minnesota. January lows average about 2 degrees, and the area sees roughly 172 nights a year at or below freezing. July highs average around 82, with about 10 days a year reaching 90 or higher. Precipitation totals about 29 inches a year, including around 44 inches of snow, and July is the wettest month at roughly 4.5 inches. These are 1991-2020 NOAA climate normals from a nearby weather station and are a guide, not a forecast.

Those 172 freezing nights are nearly half the calendar, so rodents and cold-weather insects have months to test your home. Fall is the make-or-break season: sealing gaps, installing door sweeps, screening vents and clearing leaf litter from the foundation makes it much harder for anything to move in. Winter checks of garages, storage rooms and attics catch activity while it is small.

Because July, not June, brings the most rain in Andover, mosquito pressure can hold steady well into summer. Standing water in gutters, buckets and low spots is worth emptying every few days during that stretch. After a wet July, damp mulch and soil near foundations can attract ants and spiders, so pulling mulch a few inches back from the house is a simple, useful step.
