Carpenter Ants
Unlike termites, carpenter ants do not eat wood but tunnel through it to create nests. A primary sign of an infestation is finding small piles of coarse sawdust-like material, known as frass, which they push out of their galleries. You may also hear faint rustling or crunching sounds inside walls or wooden structures. Sighting large, black ants foraging inside your home is another clear indicator of a potential problem.
