I picked up on this yesterday morning , very sad.
It must be said that as keepers we need to learn how to read a hive too. If the hive warns you, be prepared, and they do warn you.
I am from Iddee's camp and seldom suit up at all, and can work 20 or more times not taking a single sting if I am cautious and methodical.
I have had my days too though, 3 times in all , taking well north of 30 stings each time, one was a cut out in an apartment with no power in mid summer, and I dressed down to just short pants, and most stings were as a result of crushing them during comb cutout or stuck to me as they fell due to sweat or honey all over me, there was no way to be dressed in a suit that day. Lawn mower was another , and I bailed as they lit me up.
But when I work my phone is with me, my suit is there if needed and I have Benadryl and Zantac in my box , plus an epipen too ( for others not me :-)
I did two shake outs this week, both hives had laying workers , but despite their queenless status , both hives were well behaved , not a sting to be had between them, if I were to hazard a guess , there is so much nectar coming in at present, they are happy.
I won't let visitors come close unless they at minimum put on a veil, and I have gloves for them too if they want to handle the frames.
Learn to read the temperament of the hive and use a small bit of smoke too. And be safe.
