TERRO ant killer. I keep this in my kitchen cabinet and the first sign I see of the ants I get it out. It is a clear thick liquid. Put a couple drops on a piece of cardboard where you see the ants and in one day most will be gone. Two days and you won't see any. Don't kill the ants. Let them eat the Torro and they will go back and die on their own. Great stuff!! I got it at Lowe's or you can find it at any nursery. Good luck.
