How to Keep Carpenter Bees Away from a New Deck
Check your home, fencing, shed and all other wooden structures on your property for the telltale holes that signify carpenter bee activity. These holes are perfectly round, about 1/2 inch in diameter and may be stained or discolored from bee feces. When you find such holes, plug them with a ball of tinfoil. If the foil remains undisturbed for 24 to 36 hours, then apply caulk around and over the tinfoil balls and holes.
