Hi Everyone,
Billy wrote in part:
"We pulled about 6 sticky boards and were only able to find one mite.  We
did an ether roll and found zero.  We used about 150 to 200 bees from three
different hives.  He also demonstrated the powdered sugar method and again
no mites.  While we had the hives open we looked at some of the drone
brood.  No mites.

Just makes you wonder what is going on.  Any other people finding the same?"

If the colonies were treated with checkmite+ coumaphos strips this is what I would expect.  You probably don't need to treat until next year and maybe not until next fall but do watch the varroa populations to know when you need to treat.
