Quote "Exterior use only. Kills powder post beetles, prevents termite attack above or below ground. Use as a primer before painting to control warping and swelling. Attractive brown color; great for decks, fences, shakes, roofs and pressure-treated end cuts. Copper naphthenate, low odor, easy water clean-up. "
I don't think I would use it in my hives. Copper naphthenate still scares me. Can't use it in your house, would want it in my bee's houses.
