Re: Found old boxes.
There is always a risk when using old equipment that it will have a disease that can infect a new colony. The one of major concern is AFB (American Foul Brood), as the spores can be viable for decades. Once the colony has AFB your choice is pretty much continuous antibiotic treatment or to burn the whole thing. Pest (such as beetles, mites or mice) are not really a problem from old hive bodies.
