I talk regularly to Tony J, your state inspector. Last January, he was
setting up observation hives for a bee meeting. He found brood in the
colonies he opened.
I treated with vaporized Oxalic last November, and had a wide range of
success. Some colonies had a large population of Varroa in early summer,
while I could find none in some yards. I'm guessing that colonies with
brood was the problem.
