Dear John, A simple ant control is to make a syrup of 1/3 c. sugar to 1 cup water. Boil to dissolve the sugar. Add 1/4 tsp Boric acid. Put in shallow container accessible to the ants. They will carry it back to their nest. Very effective stuff. Since it is poison take precautions to keep the poison from pets and children.
