Pest season in Overland

NOAA's 1991–2020 climate normals for the ST LOUIS LAMBERT INTL AP, MO station (about 4 miles away) show an average temperature of 57.4°F, about 41.7 inches of precipitation a year spread over roughly 71 days with measurable rain or snow, 85 nights at or below freezing and 47 days reaching 90°F or more. Monthly averages are at or above 50°F for 7 months, so insect activity is concentrated in a clear warm season, while 85 freezing nights a year push mice and some insects to look for shelter indoors. Average temperatures are at or above 50°F from about April through October.

Moisture and pests

Around 41.7 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 Overland is 1955, and about 91% of its 6,675 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 86% of housing units are single-family detached homes.
