Texas Pests: Identification, Seasons and What to Do

A statewide guide to common Texas household and yard pests, from fire ants and mosquitoes to termites, scorpions, ticks, roaches and wasps.

Editorial guidance reviewed 2026-08-29.

Quick answer

Texas's warm climate supports pests through much of the year, but timing and severity vary by region. Eliminate standing water for mosquitoes, keep food and moisture sources controlled indoors, seal entry points, inspect structures for termite warning signs and use Texas A&M AgriLife and local extension guidance for identification and treatment. For dangerous infestations, structural termites or uncertain pesticide use, use a licensed professional.

Fire ants

Imported fire ants build mounds in lawns, parks and disturbed ground and can sting repeatedly. Avoid disturbing active mounds, particularly when children or pets are nearby.

Treatment choices depend on the property and infestation. Texas A&M AgriLife's integrated approach is a stronger starting point than indiscriminate pesticide use.

Mosquitoes

The most effective household step is often source reduction: empty containers, refresh pet water and birdbaths, clean gutters and remove other standing water where larvae develop.

Mosquito activity often rises after rain and warm weather. Protective clothing and properly used repellents add another layer when exposure is high.

Termites

Subterranean termites can cause expensive structural damage while remaining hidden. Mud tubes, discarded wings and damaged wood deserve closer inspection.

Because identification and treatment can affect an entire structure, suspected termite activity is a good reason to involve a qualified pest professional rather than relying on spot treatment alone.

Scorpions, roaches, ticks and wasps

Scorpions often enter through small gaps and may hide in shoes, boxes or undisturbed areas. Roaches are strongly associated with access to food, water and shelter. Ticks matter most where people and pets move through brush or tall grass, while wasps become a concern when nests overlap with frequently used spaces.

Integrated pest management starts with identification, sanitation, exclusion and habitat reduction before chemical treatment.

When a pest is actually wildlife

Snakes, bats, raccoons, opossums and other animals sometimes enter structures but should not automatically be treated like insects or rodents. Removal rules, disease risks and conservation status can differ.

Use species-appropriate guidance and avoid handling wildlife bare-handed.
