I have a finished log cabin made of pine, 10 years old. Lots of sawdust from insect boring holes, about 1/8” diameter. Logs were not treated other than several coats of stain log finish which appears like varnish. I see comments about strip and then borate in other posts. Is this what I need to do, and if so do I need to strip the home every 5 years? This sounds horrible.
