Take charge of house ants in and around your home with Amdro Ant Killing Bait Stakes. These easy-to-use, dual-action stakes work outdoors or inside to lure multiple common ant species. With one simple product, you can attract and kill sweet-eating and grease-eating ants - and destroy entire house ant colonies. Scout ants think the bait is food, carry it home and share it with their queen and colony. Some ants die within hours, but larger colonies take longer. Regardless, once the queen dies, the colony is doomed.
