Dear Doc.We built our pine log home in Muskoka, Ontario, Canada in 1986 and put a sikkens product on the exterior. We have never reapplied it. Now we have bees drilling holes in the logs and even in the chinking. (perma chink) I have sprayed bug killer on the logs to no avail. Can you recommend how to get rid of the bees and what stain we could use over sikkens. Or what is the best protection we can put on the logs to protect them from bees and weather.T. McMillan
If they are Carpenter Bees you should get a Bee Kit from www.timelesswoodcare.com . They make holes about 1/4” in dia. If the holes are tiny, 1/16” they could be Powder Post beetles. The only good way to stop them is to strip the entire house and apply a borate treatment. Timeless Wood Care should be able to answer more of your questions.
