Carpenter bees are a destructive nuisance…
While they will not sting you, they will destroy the integrity of your untreated wood. Carpenter bees literally burrow into wood and hollow-out your wood in order to create a space to lay their larva. The carpenter bee tunnels can extend up to 4 feet long and generally consist of many turns.
You will see small sawdust piles. When you see these piles, look up. If you see perfectly round holes about the diameter of a dime, you most likely have an active infestation.
- You will also see the giant bumble bee-looking critters hanging out around your wooden structures.
How do you get rid of these little critters?:
- You will need to find an insecticide that can be forced into the hole and into the various twists and turns of the tunnels. I found a foaming spray insecticide, Spectracide, designed specifically for carpenter bees and yellow jackets. The foam is great because it expands to fill the tunnels. The spray also comes with a long, skinny nozzle that you can insert into the holes.
- You should also kill as many carpenter bees as possible. They are easy to kill because they are rather slow and clumsy. One website suggested using a tennis racket to knock the bees out of the air and onto the ground so that you can step on them. This would definitely make you the talk of the neighborhood!
- A few days after treatment, you need to fill the holes. I like using expanding insulating foam because the foam will actually provide much needed integrity to the damaged, hollowed wood.
- After the foam dries, even the surface and PAINT over it. The paint wild act as a deterrent for future infestations.
