Mix 1/3 cup granulated sugar with ONE teaspoon (no more!) boric acid powder (available at drug stores). Add 2 cups water. Mix very well. Keep this bait refrigerated. Pour the bait over a small piece of sponge which you have put in either a small glass jar (like a votive candle holder) or a small margarine container with a lid in which you have punched holes (if you have pets that might ingest it). It takes about a week to get a high percentage of kill on the ants. Refill jars twice weekly in hot weather. Toss sponge and clean jars every couple of weeks.
