I have a very heavy infestation of carpenter bees, There are hundreds of holes bored into the logs. Several of the bees have made it into inside the cabin as well. I have treated the logs with a spray on insecticide and a dust application as well. The cabin is about 30 years old and is due for a staining. My question is what do I need to treat the bee holes and what do Ineed to do to prevent them from coming back. Will the stain help prevent the bees for wanting to bore into the logs?
