Carpenter ants use their extremely strong mandibles to hollow out channels in wood to build their nesting areas. When found outdoors, carpenter ants are not a serious threat to your property. However, once a colony finds its way inside, you want to consider carpenter ant treatment and extermination as these ants can cause significant and costly damages. Unlike termites, they will not eat wood. However, as their nests and colony grows over time, they will weaken the structural integrity of your home. Furthermore, the existence of carpenter ants may be an indicator of rot or moisture which can lead to significant structural damage over time.
