Yes, we offers pest control services for carpenter bees. Carpenter bees chew tunnels in wood to make a nest cavity in which their larvae can grow. To prevent the bees from making the holes, the surfaces being attacked may be treated using a residual liquid product. If the holes are already present, a dust product may be applied into the holes and then the surrounding wood treated with the liquid product. Such treatments may need to be repeated after a couple of months to further deter the bees. You can consult a professional for a comprehensive inspection and treatment plan.
