I tried to use some of the wood for a project recently, and noticed small holes (filled with frass) in the heart wood. Now I speculate there are powder post beatles. After reading posts from this thread, I thought a possible solution to salvage the wood would be to mix Timbor with water and spray. I planned to leave the treated stack in my garage a little while longer before use, reasoning that emerging beatles will die when they ingest the treated wood from the surface layer.
I'm now a bit concerned after reading Mike's comments regarding boric acid being toxic to humans.
What's the best way to treat this problem with maximum wood salvage?
