I have seveal full depth boxes that are starting to rot. (I am located in Far North Queensland, Australia) These boxes were painted only, I have been told that soaking them in copper Napthanate will preserve them for many years but I am not sure how to do this just yet, I am sure it is not hard. I just have to get the material and a bath for them. I have seen articles on polystyrene hives and there were people using plastic hives some years ago but these seem to have faded into the distant past. I am interested in any updates on hive material aother than wood thanks Andrew Weinert Atherton, Tropical North Queensland Australia 17.17 Degrees South, 145.30 Degrees East
