Today I checked all 15 hives today and was very surprised to find all are
doing fine.  This is the first winter since I started using only FGMO to
treat my bees for mites. I usually have 1 or 2 hives by this time that
havent made it. This is not a scientific study just my own observation.
Looks like all 15 hives will make it in very good shape with plenty of
stores left.
