Years ago on another forum, there was a discussion started by Dean Torges where he was talking about wood wasps getting into his big pile of osage logs. He was looking for a simpler solution than constantly going through his stash of wood, and spraying chemicals, etc. I believe he ended up taking someone's advise and throwing the logs in the pond. The bugs left them alone and the wood actually doesn't absorb a bunch of water and get spongy.
