Oh how I wish I could look forward to winter freezing to get rid of our ants but such is life here, where they are 24/7, 365 days a year. I use Dr. Bonner's Peppermint Soap. I mix about 1 part to 10 parts water in a spray bottle and have at those nasty ants that appear all over our house (kitchen, bathroom, living room, bedroom, inside/outside. Tried the Terro stuff and they only called more and more and more ants without any relief for many months. Finally gave up on that idea. You name it...we've got those ants; black, tiny brown, carpenter, flying black ones, etc. So I do the best I can and when I see a trail of them, out comes the spray bottle (one located in each room) and spray (which kills them) and makes their trail go cold for an hour or two.
