Pest control in Harvey, IL

Pest season in Harvey

NOAA's 1991–2020 climate normals for the PARK FOREST, IL station (about 8 miles away) show an average temperature of 49.8°F, about 42.1 inches of precipitation a year spread over roughly 76 days with measurable rain or snow, 126 nights at or below freezing and 16 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 126 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 42.1 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 Harvey is 1960, and about 83% of its 9,857 housing units were built before 1980. Homes from this era often have settled foundations, aging weatherstripping and wood trim that can let pests in, and many have crawl spaces or basements worth checking for moisture. About 28% 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.
