Use noise to get rid of carpenter bees as they are highly sensitive to noise. You can setup a sound box next to the holes or nests as this will encourage them to migrate. This is a safe and hustle free method. Using steel wool to stuff the holes is also a great idea.
My approach is: 1  First dust the bees out of the nest. 2  Once the nest is abandoned, I cut it open. 3  Next, blow out the nest with an air line, removing any dead bees.  Fill the 1  galleries. Re-paint.  Finally, spray each spring with an insecticide to dissuade the bees from returning.
