Ant Bait
Category : Hints, Tips and Tricks
1 part boric acid
2 parts mint jelly or cracker crumbs

Mix, then place the bait in a container with ant-size holes in the lid. Place away from children because boric acid can be harmful if swallowed. Dispose of the container after use.

The worker ants enter the trap, feed on the poison and carry it back to their nest. Once inside the nest, they feed bits of the poisonous material to the queen and immature ants, and the entire colony is eradicated.
