I have a real bad case of wood worms. Most of the beams have already been cut up for firewood. There are a few I need to use over and are in pretty good shape but have been eaten into a little bit. I have read that Borax based treatments or Linseed oil works well, I want to stay green and cheap. Is the Borax that they sell for laundry in the grocery store a type of treatment? How well does Linseed work? I have looked on the net but wanted some feedback here. Thanks for following along. Scott Shumaker aka SHU
