The answer to 'why do I have carpenter ant' is that carpenter ants are a common pest that can infest homes, especially in areas with damp or rotting wood. Carpenter ants are attracted to moist, decaying wood, which they use to build their nests and tunnels. They can cause significant structural damage to your home if left untreated.
Some common signs of a carpenter ant infestation include seeing large black ants inside your home, finding piles of wood shavings or sawdust, and hearing rustling or scratching noises coming from walls or floors. Carpenter ants can also be attracted to sweet foods and may be seen foraging in your kitchen or other areas of your home.
