Red imported fire ants build mounds in lawns and sting in swarms. Fire ants are a fact of life in Houston yards. Texas A&M runs a statewide Imported Fire Ant Research and Management project, and the USDA keeps a federal quarantine on moving soil, sod and nursery stock out of infested areas.

What works

Broadcast bait across the yard, then treat individual mounds.
Bait works best when ants are actively foraging.

Supplies: fire ant bait.
