I did do a November treatment after the 3 September treatments.

Yes, I understand that.

Not really as I'm the only beekeeper around my area...except for the
occasional hobbyist.
After all the OA(v) I've done, and the lack of control, I came to the
conclusion that my November treatments weren't effective because the
clusters were too tight to allow the OA to penetrate...as Medhat also
said. If I use OA again, it will be with syrup. Trouble there is my
hives have to be wrapped before the snow gets too deep as I can't get
to the hives once there is enough snow. I suppose I could get out the
snowshoes and toboggan.
