Monthly averages are at or above 50°F for 7 months, so insect activity is concentrated in a clear warm season, while 121 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 37.9 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 Northlake is 1957, and about 89% of its 4,526 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 36% 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.
