Mix four parts boric acid with four parts white flour and one part confectioner's sugar. Add enough water to make a malleable dough. Roll into 1-inch balls and place them behind appliances, around garbage cans and inside cabinets. To make the bait even more irresistible, you can add a bit of bacon grease or minced onions to the dough.
