Protect your family against the threat of fire ant bites and stings with Amdro Fire Ant Bait. This dual-action treatment attracts and starts killing fire ants immediately. Even better, it reaches fire ant colonies you see and those you don’t. With Amdro Fire Ant Bait, foraging worker ants think the bait is food and carry it back to the colony, where other ants eat it and share it with their queen. In about one week, the queen dies. Without their queen, the whole mound dies — and your family can enjoy your yard again. Also effective against carpenter ants, fleas, spiders, and mores. 2 to 4 ounces cover approximately 5000 square feet. Active ingredient: Hydramethylnon. 1 pound.
