The answer to 'why do I have carpenter ant' is that carpenter ants are a common household pest that infest wood structures, especially in damp or decaying areas. They tunnel through wood to build their nests, which can cause significant structural damage over time. Carpenter ants are attracted to moisture, so they often target areas with leaks, poor ventilation, or water damage.
Some common signs of a carpenter ant infestation include sawdust-like piles near entry points, visible ant trails, and damaged or hollow-sounding wood. If left untreated, carpenter ants can spread to other parts of your home and cause extensive damage.
