I have been using a company callde Structure for 2 years. They preovide an organic solution that works well. The guys garauntees I could dip my baby or my do in his solution it is so safe. He also sells me Bombs, that I set off for up too 5000 square feet. All I do is buy painters disposable drops(plastic sheet). I make sure they are long enough to touch the floor, and sinch them around the bottoms. The bombs are mainly for infestations. A standard treatment fro the exterminator should take care of the ants.
