When is the best time to treat with OAV ?
My honey supers are off. I have decided to winter them in doubles this year. Was going to try doing it in singles. But chickened out. Seems like the queen is slowing down laying. Last time I checked there was lots of capped brood. But very little eggs. Should I wait till all brood has hatched out? Or is it ok to start doing OAV now? Was thinking of doing 3 treatments a week apart before winter.
I have hive top feeders on the hives right now.
