how to treat bees boring into fascia boards

by

I live in a log home in Mississippi.  Carpenter bees are borng into the fascia boards and rafters on my porch.  This is an ongoing yearly problem.  How can I prevent new boring sites each year?

This is easy to stop. First, treat any existing holes with DEMISE DUST right now. Seal them with some CORKS. Next, spray with MAXXTHOR EC or NBS to prevent any new ones from coming around. More details can be found in our CARPENTER BEE ARTICLE but this approach will take care of existing bee nests and stop new ones from coming around.

Here are direct links to the information and products listed above:

  1. I have a redwood home and the Carpenter Bees usually bore into the fascia boards. I am thinking of replacing the facia boards with a plastic or composite redwood colored decking. Will they bore into boards that have plastic as part of their composition?

    Thanks!

    • @guest: I have seen them bore through painted surfaces, cement, grout and even plastic. Is this common? No. But will replacing a small section of your redwood home with this substrate stop them from nesting under the facia boards or somewhere else still left unprotected? No way! Remember, carpenter bees are attracted to the scent of the home and whether you make the change or not, they’ll still be attracted there is no doubt the redwood will continue to release a subtle odor. This odor is something they target and unless you changed structure types, something I’m afraid you’ll always have happening. And once they arrive to the home, they’ll either drill around the replaced sections or into the surrounding area which you leave unchanged. In the end, I’m sure you’ll only deter them from this one area but they’ll still be active and nesting.
      The good news is simply treating this area with either the Maxxthor or NBS listed above will keep them away. And if you have any drilled out nests now, dust them with the Demise shown above and these will be controlled instantly.
