Bexar County, TX Building Safety: Pest Control (2026)

Structural pest control services performed for hire in Bexar County, including termite treatments, general pest control for cockroaches and rodents, mosquito abatement, and wood-destroying insect inspections for real estate transactions, are licensed and regulated by the Texas Department of Agriculture (TDA) under Chapter 1951 of the Texas Occupations Code. A business must hold a TDA business license, each technician must be a licensed applicator or apprentice, and the responsible certified applicator must be at least an on-site supervisor or available within two hours. TDA requires licensed applicators to provide the customer a pre-treatment consumer information sheet explaining the products, target pests, and precautions, and a copy of each service ticket. Termite pretreatment of new construction must follow the Texas termite pretreatment regulations, including soil treatment or physical barrier installation, and the builder must provide a Termite Pretreatment Disclosure Document to the buyer. Mosquito control in Bexar County is performed at the neighborhood level by cities and at the countywide level by the San Antonio Metropolitan Health District, particularly during West Nile and Zika virus surveillance periods. Homeowners performing pest control on their own property are not required to be licensed but must follow pesticide label directions.
