The answer to 'how did carpenter ant get in my house' is that carpenter ants often enter homes through cracks, gaps, or holes in the exterior. They are attracted to damp, rotting wood and may build their nests inside walls, floors, or other structural elements of the home. Carpenter ants don't actually eat the wood, but they tunnel through it to create their nests, which can cause significant damage over time.
Some common signs of a carpenter ant infestation include seeing the ants themselves, finding piles of wood shavings, and hearing rustling or clicking sounds inside the walls. If you suspect you have a carpenter ant problem, it's best to call a professional pest control technician to properly identify the issue and recommend the best treatment. DIY methods may be effective for small infestations, but larger problems often require specialized treatment to fully eliminate the colony.
