Carpenter ants do not typically bite humans, but their bites can cause a sensation similar to a bee sting, which may result in a small amount of bleeding. However, these bites are not dangerous to most humans and typically lead to only minor skin irritation. Carpenter ants are most likely to bite when their nests are disturbed or when they feel threatened. If you encounter a Carpenter ant, it is best to back away slowly and avoid any behavior that might provoke the ant.
