In Australia, bee boxes are usually made from hoop pine, which is an inexpensive soft wood. The only problem is that it is prone to wood rot in hot humid conditions. The result is that boxes that are not treated with fungicide may only last a few years before they fall apart. Most commercial beekeepers dip their hives in fungicide - either copper napthalate or copper-chrome-arsenate (CCA) to prevent wood rot. Another common technique is dipping the hives in hot paraffin wax to seal the wood. As our main objective in beekeeping (and growing our own food generally) is to avoid exposure to toxic chemicals, the last thing I want to do is put copper napthalate or CCA in bee hives when there is a good chance that these chemicals will end up in the honey and beeswax that I want to harvest. Additionally, these are both pesticides, and can't be good for the health of the bees either. Paraffin wax is better, but still a product derived from petroleum and hardly natural. When we made...
