Get Rid of Ants with cornmeal. Put small piles of cornmeal where you see ants. They eat it, take it 'home,' can't digest it so it kills them. It may take a week or so, especially if it rains, but it works and you don't have the worry about pets or small children being harmed!
Rid ants with a Borax paste. Ants carry it back to their colony, it kills the whole nest. Mix 1 teaspoon borax or boric acid and 1 teaspoon sugar or honey with enough water to make a thin paste, and put the mix in a small jar near where the ants have been foraging.
