The answer to 'why is my carpenter ant invasion' is that carpenter ants are wood-destroying insects that can infest homes and cause significant structural damage. They typically nest in moist, decaying wood and are attracted to areas with water damage, leaks, or high humidity.
Common signs of a carpenter ant infestation include seeing large black ants, finding piles of sawdust or wood shavings, and observing damage to wooden structures like floors, walls, or window frames. Carpenter ants can also be a sign of a larger moisture problem in the home that needs to be addressed.
