I don't understand why long brood breaks are often recommended. All it
takes is to confine the queen to a comb for two weeks, in order to create
a brief window seven days later in which there will be no capped worker
brood, and perhaps only a trivial amount of capped drone brood about to
emerge. Removal of the trap frame at that time, coupled with an OA dribble
will eliminate most of the mites in the hive.
During springtime, I routinely confine my breeder queens to a single comb.
It's easy to do with home-made division boards with a section of queen
excluder in the middle.
It seems that some people are confusing a brood break without treatment
with a supposed benefit from a brood break alone, which actually doesn't
reduce varroa that much.
