These guys are big fans of wood, especially unfinished or weathered wood like fences, porches, etc. where they dig tunnels to make nests, thus their name. Rarely living in social nests, these bees are solitary creatures. Carpenter bees are not aggressive or dangerous, especially male bees, as they don’t have a stinger. Having short mouthparts, these bees are especially important in pollinating shallow flowers which are rarely pollinated by other insects.
