Finski, do you think Varroa does better in cold or warm?
In cold, the bees are in a tight cluster and it would seem the Varroa might have an easier choice of hosts to suck on. If the bees are warmer and spread out more, maybe more Varroa falls off the bees and lowers the amount of mites in the hive?
I have no idea, I’m just wondering if you have an opinion based upon your experience?
