We are thinking of purchasing a 25 year old log home. A recent report by a qualified inspector found powder post beetles. They are recommending that the home be tented to treat the problem.
What is the best product to treat with, safety /efficacy.
Should the home be inspected by someone else to determine structural integrity.
Will this be an ongoing issue with this home.
Tenting can be harmful to some log homes. If it is the style of log that has a gasket in between each log, the gas from tenting can break down the foam gasket and cause leaking to occur. I would recommend corn blasting the finish off and having a good quality borate treatment applied and then re-stain. It will probably be about the same cost and you end up with a fresh new finish. Use a borate with a glycol base so that it penetrates the wood deeper. As for structural integrity, powder post beetle typically will not be a problem.
