Pest control in Mercedes, TX

Pest season in Mercedes

NOAA's 1991–2020 climate normals for the SANTA ROSA 3 WNW, TX station (about 8 miles away) show an average temperature of 74.7°F, about 24.6 inches of precipitation a year spread over roughly 36 days with measurable rain or snow, 2 nights at or below freezing and 166 days reaching 90°F or more. Monthly averages never fall below 50°F (the coldest month averages 60°F), so ants, cockroaches and other insects can stay active outdoors year-round rather than going dormant for winter. Average temperatures are at or above 50°F all year.

Moisture and pests

With about 24.6 inches of precipitation a year, Mercedes is fairly dry. Pests here are often drawn to the water a home provides, such as irrigation, leaks, drains and pet bowls, which is why kitchens, bathrooms and watered landscaping see most of the activity.

Homes and pest entry points

The median year built for housing in Mercedes is 1991, and about 31% of its 6,031 housing units were built before 1980. Much of the housing is relatively new, which usually means tighter construction, but new building disturbs soil and nests, and landscaping close to the foundation can still bring ants, spiders and termites toward the home. About 62% of housing units are single-family detached homes and 14% are mobile homes, whose skirting and crawl spaces are common entry points for rodents and insects.
