I have been renting a log home and am considering buying it. it was built in 1987 and was not very well maintained. Look like it probably was not ever restained, but most definitely was not in the least the last 10 years. And there is an unknown amount of carpenter bee damage. There a lots of visible chambers (not just the entry holes) in areas. The bees were treated with some kind of borax last summer by the landlords, but they are back. How big a nightmare am I looking at?
