The AMDRO Fire Ant Killer Bait kills the queen fast and destroys the fire ant mound. Once you distribute a circle of fire ant bait around the mound, it is only a matter of time before the worker fire ants share it with the queen. After the queen eats it and dies, her colony dies with her. The ant granules are designed for individual mound treatment but can also be used for broadcast application in outdoor areas, for total ant control.
