Carpenter ants are large, black or reddish-black ants known for nesting in wood. Unlike termites, they don’t eat wood but hollow it out to create nests, causing significant structural damage over time. They are attracted to moist, decaying wood but can also nest in sound wood. Carpenter ants can be found in homes, especially in areas like attics, basements, or wooden beams. Signs of an infestation include piles of sawdust, visible trails of ants, and rustling sounds from within walls. Early detection and professional pest control are crucial to prevent extensive damage from carpenter ants in your home.
