My husband and I have purchased a log cabin, which we are moving into in a few months. This cabin is located in SW North Carolina, and the property is surrounded by a national forest. We are dealing with carpenter bees and boring beetles. My husband has been looking into all sorts of ways to deal with these wood-damaging insects. He just bought hypodermic syringes from the local farm store to put liquid borate  in them for injecting into the holes we can see. We need a permanent solution, if there is such a thing, to keep them at bay. My husband is convinced for our first winter here we will have to go around the building injecting the holes we can see.
There seems to be a major shortage of good workers up here who can help us out, so for now we will take steps and hopefully by spring there will be some better suggestions on how to deal with the outside of our cabin. He has read up on stripping the paint off the logs by a method using corn cobs, then spraying those raw logs with bug deterrent to soak into the wood, followed by finishing clear coat. This of course, is pricey. $64,000.00 was a recent quote for the size cabin we have.
Also, we have read adding Bora Care  to paint to give her a coat for the winter won’t really help, so painting the building just for the winter is throwing good money into the air. The house also is in bad need of caulking, as the previous owners used the wrong caulk that shrunk, leaving a drafty home. We have some work cut out for us. I am curious to hear from other log cabin owners who have some ideas for us.
