I have a fairly fresh cut pine timber (about 8' X 5" X 8") square on 2 sides and bark still on the remainder. I was thinking of mounting this on the wall as a shelf in our lake house. I really want to leave the bark on for the rustic look. My concern was bringing into the house any bugs or fungus that might be in the bark. Is there something I can do (other than spray the log with insecticide and fungiscide) to make sure I'm not bringing in any unwanted visitors?
