Pest control in Lewisville

Denton County Public Health tracks West Nile virus and posts mosquito maps at DentonCounty.gov/WNV. DSHS said in 2023 that mosquitoes stay active in much of Texas into November and December, and it advises emptying standing water in toys, tires, buckets, clogged gutters and plant pots, plus using EPA-registered repellent.

Fire ants have their own calendar. Texas A&M AgriLife says spring and fall are the best times to apply bait, and its preferred approach is the Two-Step Method: broadcast bait, then treat problem mounds. In hot, dry summer months the ants are less active and mounds are harder to find.

Scorpions turn up too. The striped bark scorpion is the only one of Texas's 18 species found statewide, usually under rocks, boards and debris; AgriLife says stings usually cause moderate reactions, though anyone stung should be watched for an allergic response.

Structural pest control for hire must be licensed by the Texas Department of Agriculture under Occupations Code Chapter 1951, by category: general pest, termite, lawn and ornamental, fumigation and others. TDA publishes active license lists and a company search by zip code or address.

For an indoor treatment at an owner-occupied home, the technician must make TDA's consumer information sheet available; in complexes of five or more units, residents in or next to the area get 48 hours' notice.
