What are the signs of a carpenter ant infestation and how can I identify them in my home?

Signs of a carpenter ant infestation include seeing large black ants in or around your home, finding piles of sawdust-like material near wooden structures, hearing rustling or tapping sounds coming from walls, and noticing hollow or damaged wood. To identify them in your home, inspect areas where wood meets the ground, look for ant trails or nests in walls or ceilings, and listen for any unusual sounds coming from wooden structures. If you suspect an infestation, it's best to contact a professional pest control service for proper identification and treatment.
