If you go to Home Depot, in the insecticide section you will find Boric Acid, in the powder form. I am not 100% sure, but I think it is safe for animals... you sprinkle it around the perimeter of your house, and I suppose anywhere you believe they're getting in, and supposedly they won't cross over the Boric acid line. I don't think it poisons them, it just deters them from coming in. If anyone has more infor on Boric acid and ants, please share. Maybe you'll find it online. It is a natural substance, and definitely not harmful to people. Angela [Posted in FML issue 4084]
