One of my neighbors has several old empty hives sitting around her yard. They are all mediums with frames (with old dried out comb), inner covers, tops, and bottom boards. They were her fathers and she told me that mites came through and killed all the bees. This was, I believe, in the late 80's. As far as I can remember her father passed about 20 years ago. I have lived here for 18 years and the hives have been sitting outside, unused the entire time. She told me today that she might be willing to part with one of them. She also told me I would need to soak them in a lye solution to kill all the diseases in them. Obviously I would have to thoroughly check everything for mold, rot, etc. What else should I look for? Would there still be mites or other harmful insects in there after all these years?
