Best Ways to Control Fire Ants in Your Yard

Fire ants plague southeastern lawns. Their stings hurt, and mounds damage mowers. The best approach depends on infestation level, location, labor, cost, and chemical concerns.

Broadcast bait (1-2x/year): Spread bait-formulated insecticide or use outdoor bait stations. Days later, treat high-traffic mounds individually.

Individual mound treatment: For few mounds, treat each directly. Least chemical, most labor. Temporary — ants may relocate.

Full eradication program: Broadcast bait, then 4-8 weeks later apply contact insecticide. Repeat. Most expensive, most chemical, but eliminates ants in the area.

Home protection: Treat mounds near foundation. Apply barrier insecticide (chlorpyrifos or pyrethroid) around foundation. Caulk cracks. For indoor ants, use baits labeled for indoor use (abamectin, hydramethylnon, sulfluramid).
