How to Kill Carpenter Bees in Wood
How to Kill Carpenter Bees in Wood. Carpenter bees drill near perfect holes, approximately 1/2 inch in diameter, which are found on wood surfaces, including decks, window frames, overhangs and siding.

Carpenter bees drill near perfect holes, approximately 1/2 inch in diameter, which are found on wood surfaces, including decks, window frames, overhangs and siding. While upon inspection of these holes, they appear to be only an inch or two deep, the tunnels they bore can be up to 4 feet long; this is the carpenter bees' corridor, allowing them to pass freely from the nest to outdoors. If you notice bee activity near wooden areas of your home, you have carpenter bees. The entrances made by the bees must be treated to prevent further damage to your property.
Things You'll Need
Goggles
Gloves
Dust mask
Flashlight
Red cellophane
Insecticidal dust
Wood putty
Inspect the wood during the day to locate where the carpenter bees are most active. Avoid being stung by waiting for darkness to kill the bees.
Wear goggles, gloves and a dust mask for your protection before handling insecticidal dust.
Cover a flashlight with red cellophane. The bees will not be able to see the red light, but you will be able to see their drilled entrance holes.
Apply the insecticidal dust according to manufacturer's instructions to the entrance holes earlier identified.
Shower and launder clothing worn during the application of insecticidal dust.
Allow the bees freedom to pass through their drilled holes for a few days, as they will come in contact with the dust and distribute it, killing the bees in the nest.
Plug the entrance hole with wood putty to prevent future nesting tunnels.
Tips & Warnings
Keep barns, garages and other outbuilding doors and windows closed to discourage carpenter bee nesting.
Insecticidal dust is poisonous. Follow safety precautions on the label. Dispose of the empty container in a safe manner. Keep it out of the reach of children and pets.
