well hey PA, long time no hear. I have lost 2 queens to balling so far this year. Both have died shortly after the attack and i have managed to get the bees off of them both very quickly. I pulled a stinger out of one's face and the other looked good, was testing her wings in my hands, but curled up about 5 minutes later. Id say you would have to catch them as soon as they start....i literally picked up the balling bees and dropped them from about 3 inches to break them up.
