We are new to beekeeping this year. We have come across some used hives that have drawn comb in them. Just wondering if this is ok from a pest perspective? The owner said he "thinks" maybe his bees died off because of varroa because he hasn't treated in several years. He said there was even a little honey left. They have been through a freeze so I know that will kill varroa but would it be ok to use these or are we just adding problems we don't need? Thanks so much!
