A couple of days ago I worked with the hives. Was suited up. I did not have bee gloves on, but did put on some leather cycling gloves. They are better fitting more flexible and I thought I would give them a try.
I am pretty sure I got zapped through them, but did not see sacs on the gloves. I felt a jab and it hurt while working on two fingers. I fully expected to see swelling etc later but that did not happen.
Is is possible to get partially strung. Ie can the stinger penetrate enough to break skin without getting barbed. Its also possible the stinger and sac disloged while I was working
That would not explain not having a reaction to the venom in a sting. I usually have a black dot as well.
