My mom makes homemade ant bait by combining Water, Sugar, and Borax, putting it in a plastic container lid, and setting it out wherever they go. Dissolve a cup of sugar and a tablespoon of borax in a cup of hot water. Sprinkle some on a flat lid. If you have pets, little kids, or anything else that you don't want to eat your toxic ant poison, put a matching cup on top of the lid with holes cut in the sides to let the ants in. They'll take it back to their nest and feed it to the queen and all their friends and then they all die.
