The answer to 'how did carpenter ant get in my house' is that carpenter ants typically enter homes through cracks, crevices, or other openings in the exterior. They are attracted to moist, decaying wood and may nest in areas like window frames, roof eaves, or even within the walls of your home. Carpenter ants don't actually eat the wood, but they tunnel through it to build their nests, which can cause significant structural damage over time.
Identifying the signs of a carpenter ant infestation, such as sawdust piles, discarded wings, or the ants themselves, is the first step in addressing the problem. Eliminating their access points, repairing any moisture issues, and using targeted baits or insecticides can help control the infestation. However, if the problem is severe or you're unsure of the best approach, it's generally recommended to call in a professional pest control technician who can properly identify the issue and implement a comprehensive treatment plan.
