You can get rid of the colonies in your yard and keep new ones from establishing — but “permanent” requires ongoing protection, because red imported fire ants continuously re-invade from surrounding land, especially in East Texas.
Why do fire ant mounds keep coming back?
The red imported fire ant is an invasive species that thrives across the South, and East Texas's warm climate keeps it active most of the year. Two biology facts explain the frustration: mated queens fly in from neighboring properties after rains and start new colonies invisibly underground, and disturbed colonies simply relocate a few feet away. Kicking a mound doesn't kill a colony — it moves it.
What's actually under the mound?
The visible mound is a heat-regulation structure over a network of tunnels that can extend several feet down and outward. The queen — the only ant that matters for elimination — stays deep and protected. That's why boiling water, gasoline (please don't — it kills grass and contaminates soil) and surface sprays fail: they harvest workers while the queen keeps laying.
When are fire ants most dangerous?
Most of the year in East Texas, but especially after summer rains push colonies upward and during yard-heavy seasons when kids and pets are outside. Fire-ant stings are genuinely medical: they attack in numbers when a mound is disturbed, each ant stings repeatedly, and a small percentage of people have serious allergic reactions. For toddlers and dogs who can't read the warning signs, an infested lawn is a real hazard.
What are the failure modes?
- Mound-by-mound whack-a-mole — treating visible mounds misses young colonies that haven't built one yet.
- Home-remedy folklore — grits, club soda and dish soap have all been tested and don't eliminate colonies.
- One-and-done treatments — without follow-up, re-invasion from surrounding land restarts the cycle within a season.
What actually works?
Whole-yard treatment that reaches the colony: broadcast-applied products foraging workers carry to the queen, plus direct treatment of active mounds for fast knockdown, on a maintenance cycle that intercepts newly-landed queens before they establish. Spot On treats fire ants as part of our home pest control program — whole-yard coverage, direct mound treatment, and lasting colony control, with products applied responsibly by trained, licensed technicians so the lawn goes back to barefoot duty. We treat yards across Lufkin, Nacogdoches, Huntington and all of Deep East Texas.

Quick questions
How fast do fire ant treatments work?
Direct mound treatments knock down activity within days; broadcast colony control works over one to a few weeks as workers carry product to the queen. We'll retreat as needed — results are backed by our satisfaction guarantee.
Are fire ant stings dangerous to dogs?
They can be. Dogs investigating mounds get swarmed on the nose and paws, and multiple stings or allergic reactions warrant a vet visit. Keeping the yard treated is the reliable prevention.
Why did mounds pop up right after it rained?
Rain softens soil and pushes colonies upward, so mounds appear (or grow) overnight after storms. Rain also triggers mating flights — new queens landing in your yard — which is why maintenance treatment matters more in the wet season.
