I have a Moosehead cedar log home built in 2001 and in addition to two major support beams being replaced due to deep cross check splits and torquing I also have numerous knot holes drying out or crumbling out. I also have evidence of round holes on the outside (some type of boring insect) and tons of small to large black ants every summer that come out from under the walls in the bathroom and kitchen. The cabin is otherwise OK but there are many small problems including areas where the logs hav


The black ants are around because there is wet, rotten wood. The bore holes are probably Powder Post Beetles. Best way to get rid of them is have a borate applied. They are probably OK, but you should have a structural engineer look at those beams.
