Raid Ant Baits III kills ants where they hide for up to 3 months. Baits fit along paths commonly traveled by ants. Ants are attracted to the bait to feed. After ants feed on the bait, they return to the colony and transfer the bait to the queen and the others, thereby killing the entire colony. For maximum effectiveness place all baits at the same time. Use indoors in corners, along walls and near entry points. These baits are child-resistant.
