Borax ant bait. Borax is the most common ingredient in house ant control products, and get this: it's absolutely 100% natural. The best way (in my opinion) to use Borax is to mix 1 cup of warm water with 1/2 cup of sugar, and 2 tablespoons of Borax. Then soak the Borax mixture up with cotton balls and place those cotton balls near any trails the ants have established in your home. Feeding frenzy... tomorrow they'll be gone
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, and move to ant heaven. 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!
