Carpenter ants are big, often black, and bore tunnels into wood to make their nests. If the wood happens to be your house, they can cause serious damage.
One of the best resources for all around advice about how to eliminate carpenter ants, including real hands-on help, is
Beyond Pesticides (BP). Once you land on their page, pull down the “INFO” menu, and click on alternatives. Note in BP’s literature that they report that carpenter ants only survive in a very narrow temperature range, and specialists can eliminate carpenter ants by “baking them out!” Another option is BoraCare, a product recommended by BP as a least-toxic approach to killing carpenter ants, and is a product that needs to be applied by a licensed exterminator. It might be worth your while to ask your local exterminator to be trained in the use of BoraCare!
