Pest control in Owatonna, MN

Pest season in Owatonna

NOAA's 1991–2020 climate normals for the OWATONNA, MN station show an average temperature of 44.8°F, about 35.5 inches of precipitation a year spread over roughly 65 days with measurable rain or snow, 160 nights at or below freezing and 9 days reaching 90°F or more. Only 5 months average 50°F or more, so the outdoor insect season is short, and the long cold season (about 160 freezing nights a year) is when mice and overwintering insects most often move into buildings. Average temperatures are at or above 50°F from about May through September.

Moisture and pests

Around 35.5 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.
