Pest control in Winona, MN

Pest season in Winona

NOAA's 1991–2020 climate normals for the WINONA DAM 5 A, MN station show an average temperature of 46.7°F, about 34.4 inches of precipitation a year spread over roughly 68 days with measurable rain or snow, 148 nights at or below freezing and 12 days reaching 90°F or more. Monthly averages are at or above 50°F for 6 months, so insect activity is concentrated in a clear warm season, while 148 freezing nights a year push mice and some insects to look for shelter indoors. Average temperatures are at or above 50°F from about May through October.

Moisture and pests

Around 34.4 inches of precipitation a year is moderate. Moisture problems such as leaky gutters, damp basements and wood touching soil are usually what draws termites, carpenter ants and cockroaches to a particular home.

Homes and pest entry points

The median year built for housing in Winona is 1955, and about 74% of its 11,540 housing units were built before 1980. Older homes tend to have more gaps around foundations, utility lines, windows and doors, plus older wood framing, which gives mice, ants and other pests more ways in. About 40% of housing units are in buildings with two or more units, where cockroaches and bed bugs can move between neighboring homes through shared walls and plumbing.
