Continuing the saga... I did a full inspection of the hives a week ago, and
opened about 30 drone cells and no varroa. Before OAV I would expect at
least one at this time. So, it appears that the sticky board results
reflect the actual mite load in the colonies- which is that it is hard to
detect any. I am awaiting a reading from one of my mentees to see the mite
load on his overwintered bees and also his packages.
