MY log home is 9 years old and is white cedar. The past few years I have noticied that in the knot holes some type of insect only attacks these holes. They dig it out and I have been finding what appears to be small pieces of leaves used for some type of nesting. I never treated my logs prior to staining them. Didn’t know and was not advised to do so by the builder. I stain my hose with a product know as Wood GUard. When I find a knot that has been worked on by these inscects I will dig it out
