What or How does one prep cork for the mounting of orchids? We had a pet shop close and I picked up some nice size slabs of raw (seems like right off tree) cork from the reptile section for very cheap. I say raw cause it seems to have some of the inner part of tree,looks like forest humus, in it. I want to make sure there are no Bugs on it as I saw something crawling around, before I bring it into house with the orchids. As of right now I have sprayed with a neem pyrenthin Mixture.
