If you're searching for how to get rid of ants in the house, you've probably already tried the traps and sprays. It may knock down the ants in your kitchen for a day or two, but the colony survives. Here’s how we get rid of ants for good:
- Inspect the property and identify the species of ant before moving forward with a treatment plan and quote.
- Deploy kid- and pet-safe compounds that attack the colony at its source and eliminate the queen.
- Seal entry points, treat the perimeter, and lay down repellent to prevent reentry, with quarterly service available to keep new colonies from getting a foothold.
Colt Pest Control technicians were here when the first waves of invasive fire ants entered the region, and we still hold a little bit of a grudge. If you're wondering when to call pest control for ants, the honest answer is as soon as you see a trail. The colony behind it is always bigger than it looks.

Frequently Asked Questions
What types of ants does your pest control service treat?
Colt Pest Control is capable of treating and eliminating every ant species that causes trouble in San Antonio and Schertz, including fire ants, carpenter ants, Argentine ants, and Caribbean crazy ants—plus the sugar ants and red ants that march through Texas kitchens every summer. That’s why we recommend starting with our “Preferred” plan if you’re interested in year-round service.
How does Colt Pest Control stop ants from returning?
We eliminate the colony, not just the ants you see. That's the difference between professional pest control for ants and a can of spray.
Carpenter ants nest inside wood, so we locate and treat the nest itself before it damages your home. Argentine ants build sprawling networks of connected colonies, so we treat the whole system and then seal entry points and treat your perimeter to prevent reentry. Quarterly service under a protection plan keeps it that way.
Do you stop ants outside and inside my home?
We do both because one doesn't work without the other. Inside, we treat trails, nesting spots, and the cracks and crevices ants use to travel. Outside, we treat mounds and create a protective perimeter around your home.
Outdoor barriers are necessary for all ants in San Antonio and Schertz, but how and where we place barriers is especially critical to stop Caribbean crazy ants. Without barriers, which are pet and human safe, these ants swarm in huge numbers from outdoor nesting sites and will overwhelm a house if they aren't stopped in the yard first.
Colt Pest Control has come to the rescue of homeowners and businesses across San Antonio and Schertz for twenty years. We eliminate anything that crawls and creeps its way into your home.
