How does one safely eliminate acrobat ants in an exterior wall of unheated sunporch? Professional exterminators want to hit them with four different high-power toxins, including fogging room, using a granular bait outside, and spraying entire perimeter of house. I see occasional signs of the ants in the sunroom--they seem to be removing some kind of insulation from wall and enter room through thin seams in trim around window. Room has lots of plants but no human food, fire wood, or shrubs against outside wall. The windows were recently replaced and that seems to have stirred them up.
