What Varroa treatments are used? I doubt if it is resistance since you
say many different treatments are used. Could also be tracheal mites, a
mite we tend to overlook. Mimics a lot of other problems. Wanes in the
spring and summer but comes back strong in the fall/winter.
I doubt if it has anything to do with the Varroa treatment but might be
pesticide kill from some sort of late year spraying/dusting.
Since it is universal in your area, those are my best guesses.
