Eric,
Having your bees down to two supers for winter prep, I would not
recommend 4 strips of Apistan in the top super. I think 4 strips would
not give you anymore varroa control than just two. You could get away
very well with placing two strips in the top super (appropriately spaced
in the cluster). Why?
Although the colony will be very crowded during this fall application, a
fair number of bees will vacate the hive over the course of the 45 day
treatment. The temperature regime in Alberta at this time still ensures
considerable bee activity inside the hive, ensuring good dispersal and
distribution of the fluvalinate during the application period. At the
same time, brood will dwindle rapidly and by the time you are ready to
pull the strips out (I trust you are one of those conscientious
operators that does NOT leave the strips in all winter!), the little bit
of brood that is still there if any, is in the top super anyhow.
