Our approach
Fire Ant Control for St. Augustine Grass in Georgia
Fire ants colonize St. Augustine lawns, and their mound-building activity damages the thick stolons that St. Augustine relies on for spread. We use broadcast bait to suppress colony networks across the yard and individual mound treatments for immediate elimination. Keeping mound damage small protects St. Augustine’s ability to fill gaps.

Common questions
St. Augustine Grass Fire Ant Control Questions
Do fire ants cause different damage in St. Augustine than bermuda?
The mound damage is similar, but St. Augustine’s thick stolons are more easily disrupted by the soil displacement. Bermuda has both stolons and rhizomes (underground runners), so it recovers from mound damage faster. St. Augustine relies entirely on surface stolons, making each mound more impactful.
Are fire ant treatments safe for St. Augustine?
Yes. Both broadcast bait and individual mound treatments target ants through ingestion and contact, not through the soil or grass. The products don’t affect St. Augustine’s root system or stolons. We apply at labeled rates that are safe for all warm-season grass types.
How quickly does St. Augustine recover from fire ant mound damage?
Once the colony is eliminated and the mound is leveled, St. Augustine fills the damaged area from the edges in 3-5 weeks during active growth. Larger mounds that killed a wider area may take longer. Prompt treatment keeps mounds small and recovery fast.
Why do fire ants keep coming back?
Fire ant colonies have multiple queens and can relocate quickly. Single mound treatments kill one colony but neighboring colonies move into the cleared area. Yard-wide bait creates a barrier.
How fast does fire ant treatment work?
Individual mound treatments show results within 24-48 hours. Yard-wide bait takes 1-2 weeks to reach full colony elimination.
