Carpenter ants can chew through the strongest studs and stringers in a house as they hollow the wooden beams out for nesting. The resulting damage can weaken the home's structural support and require expensive repairs. Professional pest control workers can remove a colony of ants, but the best practice for homeowners is to learn the best ways to keep out an ant colony and prevent the problem before it begins.
Homeowners who suspect they might have carpenter ants inside can look for signs such as piles of sawdust, rustling sounds in the walls and trails of ants between the home foundation and piles of decaying wood in the yard, noted experts with the Washington Toxics Coalition. The only way to be sure what type of ant has visited your home is to collect a few specimens in a bag or jar and have a pest control service examine them under a microscope. Identifying the insect will allow a professional to locate the nest and begin a discussion of solutions, such as spraying a pesticide outdoors or sprinkling powder inside the walls. Another option is laying out chemical baits, convincing the ants to emerge from hiding and ingest the poisons themselves. For the safest approach, consult with a pest management service such as Abell Pest Control Inc.
