Amdro is a bait. Worker ants carry it into the mound as food for the colony. They eat and feed it to the queen. Amdro starts to kill ants immediately. In about a week the queen is dead, which destroys the mound.
For large, infested areas: using a hand-held granular spreader, broadcast Amdro at 2 to 4 ounces per 5,000 square feet (1 to 2 pounds per acre).
For individiual mounds: sprinkle 2 to 5 level tablespoons of Amdro around the mound. Do not disturb the mound. Use a disposable scoop (do not use a kitchen utensil). For best results, apply Amdro when ants are active. Repeat application as needed.
