Answer: You can try pouring boiling water or vinegar into the openings in the hills, or a product called Amdro, sprinkled according to directions on label around each mound. Another product, called pic liquid ant killer, will also work. Both are available online at Garden's Alive. Either product is eaten or carried back to the queen(s) by the worker ants. Within a few days, (be very patient), the queen dies and the whole colony is destroyed, never to return - unless you miss a mound, or stir the ants up first with a board or stick and scatter a few that may start another colony in a new location. If not, you can rest assured that these two products work exactly as described, except on carpenter ants. That's an ant of a different color/story, and requires professional treatment.
