Common Pests in Texas

Texas's warm climate, high humidity along the Gulf Coast, and vast geographic diversity create ideal conditions for a wide range of pests. From subterranean termites causing billions in structural damage to fire ants colonizing every county in the state, pest pressure in Texas is year-round and region-specific.

Understanding which pests are active in your area — and when they peak — is the first step toward effective control. Below you will find detailed guides on the most common pests in Texas, including identification tips, health risks, treatment options, cost estimates, and prevention strategies. Whether you need general pest control, termite treatment, or wildlife removal, our guides link directly to licensed providers verified through the Texas Department of Agriculture (TDA) TPCL licensing database.

Texas pest activity follows a seasonal pattern. Spring (March–May) brings termite swarms, fire ant mound activity, and mosquito hatches as temperatures climb. Summer (June–August) is peak season for scorpions in the Hill Country around Austin, wasps nesting under eaves, and flea-and-tick season for pet owners. Fall sees rodents moving indoors as nights cool, while Gulf Coast cities like Houston and Corpus Christi deal with mosquitoes and cockroaches well into November. Even winter brings challenges — South Texas remains active year-round, and Dallas–Fort Worth homeowners often discover rodent infestations during the coldest months.
