Jim... It's the standard government agency response I have heard it before..... They have to give that answer and always do in lectures. I know some other keepers here in the keys and extreme south Florida and yes there are hives that are more aggressive than others but there are no reports of insane aggressiveness that anyone has reported that I am aware of and that sort of stuff makes the news and word spreads.
Those three hives that went crazy on me same day last weekend all exhibited the "boil out" trait as soon as I cracked the lid and smoke didn't seem to help,,,, had me horribly worried because they were so atypical of what I had seen and all came from the center of my trap line.... But a week later they are calm as kittens still small but I will watch them... I am not about to go getting genetic testing on any and all swarms... Just monitor aggressiveness and if it gets marginally unacceptable her majesty goes for a dip in the alcohol... I have three in there. 2 were drone layers and one was marginally aggressive ... She got the pinch.
I respect all the guys on YouTube who work unveiled but I would never do that... Stings don't bother me like they used to but face and head stings hurt... And it's easy to be cautious and suit up. Hell the few times I have worked in shorts or open toed shoes early on I regretted it...I am careful and will continue to be...as far as open air and water meter bees yes I have heard they are more prone to have AHB characteristics and I always glove up and tape cuffs on a removal until they prove me wrong and then I start peeling off the layers... This time of year it's a race between the girls proving they are nice and me dying of heat stroke ;~)
