I just bought some unassembled supers and frames from a guy who was getting rid of some of his hives. Along with the new stuff, I got two hives that were sitting outside with old comb and no bees(he had never put bees in them--had gotten them from someone else). There are also several old supers with old frames containing undrawn foundation. I don't see any wax moths, but am not experienced enough to tell for sure. My question is how safe is it for me to keep the old hives and supers without being worried about AFB or other problems? thanks in advance for any advice.
