Amdro Fire Ant Bait Granules deliver results you can count on. Ants think the bait is food, so they take it back to the colony to share. Once the queen and other ants eat it, the whole mound dies. With AMDRO®, it's GAME OVER for fire ants. 2–5 tablespoons per mound. Destroys mound within two weeks of application. Also kills carpenter ants.
