At Once Pest - Baltimore, Maryland Pest Control Expert Specializing in Bed Bug Extermination and Wildlife Exclusion

Now that the spring warm weather is finally here, carpenter bees become an issue for homeowners. They are big, bold, in your face bees that are scary. Carpenter bees are not terribly aggressive, but they bore through wood, lay eggs and close it in a special cell complete with its own food supply - a combination of pollen and regurgitated nectar. One of these tunnels or galleries can contain up to 6 sealed cells and can be 6 inches long. Galleries used by multiple bees can extend up to 10 feet. Even if the larva inside the galleries is killed, the adults can come back later, even over winter, in these tunnels and it will be back to business the following spring.

What we recommend doing is not only killing the developing larva, but if possible wrapping the wood in aluminum flashing so that the carpenter bees can never use that wood again. It may cost a little more but it is a permanent solution that helps protect your biggest investment - your home.
