We have an invasion of the carpenter bees here in North Georgia. They are literally eating the front porch off our house. We have tried sprays, powders, filling the holes, you name it, all in vain. Is there anyone out there who can help us get rid of them? Surely there is something? A type of paint that repells them, etc? We are at our wits end, and our porch is 12 X 64, so they have lots of wood to ruin. Any suggestions would be appreciated.
