The front of my home has been taken over by carpenter bees. They have drilled holes in the trim of my house. I can't find any help on what kind of pesticide to use. I've been told that I need to replace the wood trim around my house. Any suggestions would be appreciated. thank you.

From an organic approach, spray with boric acid solution, then stuff steel wool in the holes.

Thank you for your help.

I know this is a little late, but I just saw your note. We had a really bad carpenter bee problem with our cedar shingle siding. No pesticide worked so we bought a jar of cayenne pepper, made a watery paste with it, and painted it on the areas the bees were interested in. It worked like a dream.

Just read your post about carpenter bees. Don't know that I have the answer but we did have very large numbers of the carpenter bees in SE TX and they did extensive damage to the facia boards, and others, on the house. Tried many remedies but none worked or they weren't really feasible to do. There were thousands of holes I'd estimate. And the Pileated Wood Peckers tore the dickens out of the house getting at the larvae. We replaced the wood with pressure treated lumber and now the bees act as if it tastes bad to them. Can't say for sure if this is the solution but it certainly APPEARS to be one for the time being. Of course pressure treated lumber is nasty stuff to work with from a personal health perspective and you must be really careful to read the directions on handling it and follow them.
