Ant Control

Ant Control for Austin Homes & Businesses

With an Associate Certified Entomologist leading the company and a Staff Entomologist on our team, we bring a level of technical depth to ant control that many Austin pest control companies don't offer. Rock Thweatt has spent nearly four decades in the pest control industry, and his son, Steven Thweatt, serves as our Staff Entomologist and Certified Applicator. That knowledge base shapes every treatment we plan.

We've served the Greater Austin area since 1959, and in that time we've handled ant problems in homes, restaurants, offices, and everything in between. Austin's heat, humidity, and heavy rain cycles make ant pressure a year-round reality here. Fire ants rebuild mounds after every storm. Carpenter ants can damage structural wood. Odorous house ants appear in kitchens without obvious explanation. Surface sprays may slow them down temporarily, but targeting and disrupting the colony is what addresses the problem more directly.

We serve both residential and commercial properties throughout the Greater Austin area. Same-day service is available, and we offer free estimates to property owners. Our A+ rating from the Better Business Bureau reflects the standard we hold ourselves to on every job.

Ready to put a stop to ant activity on your property? Call us today at (737) 348-0893 or request your free estimate. We can often schedule same-day service.

Common Ants Found in Austin Properties

Not all ant problems are solved the same way. Fire ants, carpenter ants, odorous house ants, and Argentine ants are all common in the Austin area, and each responds to different treatment methods. Identifying the species is the first step toward an effective treatment plan.

Signs You Have an Ant Infestation

Some ant sightings are incidental. Others signal an active colony that may continue without targeted treatment. Here's what to watch for:

  • Trails to food or water sources: Consistent lines of ants moving toward kitchens, bathrooms, or pantries point to active foraging from a nearby colony.
  • Fire ant mounds in open soil: Mounds appearing near driveways, lawn edges, or garden beds indicate established outdoor colonies.
  • Sawdust or wood shavings: Small piles near baseboards, window frames, or structural wood suggest carpenter ant activity.
  • Winged ants indoors: Swarmers appearing inside, especially after rain, may mean a mature colony is nesting within the structure.
  • Repeated DIY failures: If store-bought treatments keep losing ground, the colony likely hasn't been located or reached.

Our Ant Treatment Approach

We start with an inspection to identify the species and locate likely colony sites. That distinction matters because fire ants require different methods than carpenter ants or odorous house ants, and the wrong approach wastes time.

Treatment planning draws on the entomological background of both Rock and Steven Thweatt. Depending on what we find, we may use baiting products that foraging workers carry back to the colony, perimeter treatments that disrupt entry points and foraging trails, or targeted colony treatment for outdoor infestations. We select treatment methods based on the property, pest activity, and application needs.

For ongoing ant pressure, we offer custom protection programs that address conditions between visits and help reduce the risk of re-infestation. One-time treatments are also available for customers who need a single-visit service. We'll recommend the approach that fits your situation after the inspection.

Frequently Asked Questions

Do You Handle Both Indoor & Outdoor Ant Problems?

Yes. Our ant control service addresses both indoor activity (kitchens, bathrooms, entry points) and outdoor colonies, including fire ant mounds, perimeter nesting, and yard infestations. Most ant problems involve both, and we treat accordingly.

How Long Does Ant Treatment Take to Work?

It depends on the method and the species. Perimeter sprays work quickly on surface activity. Baiting products are slower by design. Foraging ants need time to carry the treatment back to the colony. We can explain what to expect based on what we find at your property.

Do You Offer Ant Control for Commercial Properties?

We do. We serve both residential and commercial properties throughout the Greater Austin area, including offices, restaurants, and multi-unit buildings. Same-day service is available, and we provide free estimates.

What Should I Do Before the Technician Arrives?

Your technician can advise you based on the treatment type. Generally, clearing food from counters and ensuring access to entry points and problem areas helps the visit go smoothly. When you call to schedule, we can walk you through any specific preparation needed.
