Pest Control in Austin, TX
Few cities mix desert and swamp pests the way Austin does. Scorpions from the Hill Country and fire ants from the Gulf plains both end up in the same backyard.
Pest control in Austin is not one job, it is several. The limestone west of the city brings scorpions and the kind of spiders that like dry cracks. The flatter, wetter east brings fire ants, tree roaches, and a mosquito season that runs most of the year. If you have moved here from a cooler state, the sheer length of the warm season is the thing that catches you out. Pests barely get a winter break.
Austin's most common pest problems
| Pest | When active | Local notes |
|---|---|---|
| Red imported fire ants | Year-round, mounds swell after spring rain | Fire ant mounds dot Travis County lawns and reappear fast after every wet spell. A single colony can hold a quarter of a million ants. |
| Striped bark scorpions | Peaks late spring through summer | The Hill Country limestone west of the city is prime scorpion ground. They slip through weep holes and turn up in tubs and on walls on warm nights. |
| American and smoky-brown cockroaches | Year-round, worst in summer humidity | Locals call the big ones tree roaches. They breed in mulch and storm drains and push indoors when it gets hot and dry outside. |
| Subterranean termites | Swarms in spring | Eastern subterranean termites are active across Central Texas and swarm on warm, still spring days after rain. |
| Mosquitoes | March through November | Standing water along Lady Bird Lake and in backyard drainage keeps the season long. West Nile virus is monitored across Travis County most summers. |

Two things drive it. First, the warm season is long, so most species get extra breeding cycles. Second, Austin's rapid growth means new builds back straight onto greenbelt and brush, which is exactly where scorpions, ants, and rodents already live. A treatment plan here works best when it covers the perimeter and the entry points, not just the inside.
What a local inspection covers
A technician walks the foundation for termite mud tubes and weep-hole gaps, checks the yard for fire ant mounds and standing water, and looks at garages and bathrooms for scorpion harborage. From there you get a plan that targets the species you actually have, rather than a blanket spray.
Preventing pest problems in Austin
- ▪Seal weep holes and foundation cracks with mesh or sealant to block scorpions.
- ▪Keep mulch and firewood away from the slab to cut roach and termite harborage.
- ▪Treat fire ant mounds in spring before they spread across the lawn.
- ▪Clear standing water in plant trays and drainage after every rain.
What treatment costs here
Most Austin homes start with a free inspection. One-time treatments suit a single problem, but with the long warm season here, a quarterly plan usually works out better value for ongoing scorpion and ant pressure.
Questions we hear in Austin
Are scorpions common in Austin homes?
Yes, especially on the west side toward the Hill Country. The striped bark scorpion is the species you will see. Its sting hurts but is rarely dangerous to a healthy adult. They get in through weep holes and gaps around plumbing, so exclusion work matters as much as spraying.
When is fire ant season in Austin?
Fire ants are active year-round in Travis County, but mounds swell and multiply after spring and early summer rain. Treating mounds early in the season stops them spreading across the whole yard.
Do I need termite treatment in Central Texas?
Eastern subterranean termites are active across the Austin area and swarm in spring. An annual termite inspection is worth it here, particularly for homes with slab foundations and any wood-to-soil contact.
Why are there so many roaches in Austin in summer?
The large tree roaches breed outdoors in mulch and storm drains. When the weather turns hot and dry, they move toward the moisture inside homes. Sealing entry points and reducing yard harborage keeps numbers down.
Is mosquito control worth it in Austin?
For homes near Lady Bird Lake, creeks, or with poor drainage, yes. The season runs March through November and West Nile virus is monitored most summers, so reducing standing water and treating resting areas makes a real difference.
