Autumn treatment was mid Oct.
That's probably one reason mite numbers are so low. The earlier you treat at the end of the season, the more chance the mites will replicate to higher levels in very late reared brood ... but the better you protect your winter bees which are probably being reared from sometime in September.
All latitude/temperature-dependent ...
Of course, if your supers came off in mid-October you didn't have a choice in the matter.
