Common Pests in Austin, TX and How to Get Rid of Them

Austin's warm climate and diverse ecosystems make it a haven for pests year-round. Here is a guide to the most common pests in Austin, TX, when they are most active, and what you can do to control them — both on your own and with professional help.

1. American and German Cockroaches

Texas is home to multiple cockroach species, and Austin homes and businesses deal with both American cockroaches (the large "water bug" variety) and German cockroaches (smaller, found indoors near kitchens). German cockroaches in particular are notoriously difficult to eliminate without professional treatment because they reproduce rapidly and develop resistance to over-the-counter products.

Peak activity: Year-round, with spikes in spring and fall as temperatures drive them indoors.

Prevention: Seal foundation cracks, repair leaky pipes, keep food in sealed containers, and reduce moisture in bathrooms and under sinks.

2. Fire Ants

Fire ants are ubiquitous in Central Texas and pose a real health risk — their stings can cause serious allergic reactions. Colonies can contain hundreds of thousands of individuals and will rebuild within weeks after surface treatment with store-bought products.

Peak activity: Spring through fall. Hot dry summers push them deeper underground; rain in fall and spring triggers swarming.

Effective treatment: Professional two-step programs use broadcast bait that worker ants carry back to the queen, eliminating the colony rather than just the visible mound.

3. Subterranean Termites

Subterranean termites cause billions of dollars in structural damage annually across the US, and Austin's warm, moist soil is perfect for them. Many Austin homeowners do not discover a termite infestation until significant damage has already occurred because colonies feed from the inside out.

Signs of infestation: Mud tubes on foundation walls, hollow-sounding wood, discarded wings near windows and doors, bubbling or peeling paint on walls.

Treatment: Soil-applied liquid termiticides or Sentricon bait systems installed by licensed professionals. Our pest control team offers free termite inspections and permanent bait station installation.

4. Mosquitoes

Austin's warm, humid springs and summers make mosquitoes a serious nuisance from March through October. Beyond comfort, Austin sees occasional activity from Aedes aegypti mosquitoes, which can carry dengue, Zika, and chikungunya.

Prevention: Eliminate standing water — even small amounts in plant saucers, gutters, and bird baths. Professional yard treatments provide 3 to 4 weeks of knockdown of resting adult populations.

5. Roof Rats and House Mice

As Austin's population and development have grown, so has the rodent population. Roof rats in particular are a growing concern in older South and East Austin neighborhoods, entering homes through gaps in rooflines, soffit vents, and tree limbs that touch the structure.

Signs: Droppings, gnawed wiring, scratching sounds in walls and ceilings at night, nesting material in attics.

Control: Professional exclusion work (sealing entry points) combined with trapping provides long-term control. Poison bait alone without exclusion just invites new rodents to fill the void.

6. Scorpions

Striped bark scorpions are common in Central Texas and can sting painfully. They enter homes through gaps in weather stripping, foundations, and utility penetrations — especially in homes that back up to natural areas in the Hill Country and surrounding Austin suburbs like Leander, Georgetown, and Dripping Springs.

Control: Professional perimeter treatment combined with exclusion of harborage areas (rock piles, debris against the foundation). UV flashlights can locate scorpions at night for targeted treatment.

7. Bed Bugs

Bed bugs have rebounded nationally and Austin is not immune. Hotels, Airbnbs, and secondhand furniture are common introduction sources. They are notoriously difficult to eliminate with over-the-counter products.

Professional treatment: Heat treatment (raising room temperature to 120°F+) or chemical treatment with multiple follow-up visits. Our team provides bed bug inspections and treatment throughout Central Texas.
