Pest Control in Winona, MN

Winona's climate is cold in winter and warm in summer. January lows average about 8 degrees and July highs about 82, with roughly 11 days a year at 90 degrees or higher and around 148 nights at or below freezing. Precipitation totals about 34 inches, including about 38 inches of snow, and June is the wettest month at close to 4.8 inches. These figures are 1991-2020 NOAA climate normals from a nearby weather station and are a guide, not a forecast.

Of the Minnesota cities in this group, Winona has one of the shorter freezing seasons, but 148 nights below freezing is still a strong push toward shelter. Mice and overwintering insects will find their way into attics, basements and utility rooms if they can. Fall sealing, tidy storage and screened vents keep them out, and a winter walk-through catches anything that made it inside.

Summer humidity and June rain add pressure of a different kind. Damp basements, leaky pipes and poor ventilation can support cockroaches, ants and other moisture-loving pests. Fixing leaks, running fans in bathrooms and laundry areas, and keeping drains clear will reduce these problems. Outdoors, dumping standing water once a week limits mosquitoes, and trimming plants back from siding gives spiders fewer places to hide.
