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!
Cornmeal is the quickest and cheapest way to kill ants. It is safe for the environment, children and pets, and does not attract other pests. Poor little piles of cornmeal near the anthill, the ants will take it home to share. The cornmeal cannot be digested by the ants and they die. It may take a week or so to see the entire colony gone, but it works.
