Mounds in the lawn
Best fire ant bait
The best fire ant bait is a granule workers pick up and carry in. Kicking a Red imported fire ant mound or pouring hot water on it gets you stung and splits the problem. Broadcast as the label allows, when the ground is dry and ants are foraging. Kitchen ant stations are the wrong product.

Which one to buy
Labeled product
Fire ant bait granules
Best standard granule — Amdro-style bait. Apply when ants are active and rain is not about to wash it away. Keep it off vegetable gardens and water unless the label says otherwise. Stings can be medical. This is not a first-aid product.
Labeled product
Extinguish Plus fire ant bait
Best when you want a slower colony bait — Extinguish Plus is the other granule shoppers compare. The insect growth regulator story is slower than a fast toxicant. Follow that label’s sites, including whether vegetables and pets are in bounds.
How not to waste the bag
Bait fails when the lawn is wet, when you disturb the mound first, or when you treat only the dome and ignore the foraging radius the label describes. Read the mound-versus-broadcast directions on the bag you bought. They are not the same rate.
A fluffy mound with no obvious center hole, and a swarm when disturbed, is the usual fire-ant picture in the South. Pavement ants and native mound ants are a different buy. If the sting and the mound do not match, stop and identify before you broadcast a second time.
Common questions
What is the best fire ant killer for a lawn?
A labeled bait workers carry home, broadcast as the bag says. A kitchen liquid station will not treat a yard of mounds.
Should I treat each mound or the whole yard?
Use the method printed on the product you bought. Some labels are mound treatments, some are broadcast, some are both at different rates.
Are fire ant baits safe for pets?
Only if you follow the label’s pet, grazing, and re-entry limits. Keep animals off the treated area for the time the bag requires. Stings themselves can be an emergency for some people and animals.
