The answer to 'carpenter ant nests' is that carpenter ants are a common pest that build nests inside wood structures. Carpenter ants don't actually eat the wood, but they excavate tunnels and galleries inside it to create their nests. Common signs of a carpenter ant infestation include seeing the large black ants, finding piles of wood shavings, and hearing rustling sounds inside walls.
Carpenter ants are often attracted to moist, decaying wood, so addressing any water leaks or wood rot issues in your home is important. DIY solutions like setting out ant baits or using insecticide sprays can help control a small carpenter ant problem, but for larger infestations or nests located deep within walls, it's best to call a professional pest control technician. They can properly identify the ant species, locate the main nest, and use targeted treatments to eliminate the colony.
