CB Borid Boric Acid Dust is labeled for all ants except for carpenter ants. You should note that CB Borid Boric Acid Dust works by ingestion and can take up to two weeks to kill ants that ingest the dust. We do have several fire ant baits that actually attract the ants, they consume it and then share it back at the colony. Using a fire ant bait product is usually more effective than using boric acid dust alone. You can see our selection of fire ant baits by clicking here: Fire Ant Bait
