Why do bees sting some people and not others. I am a mechanic by trade and I have 2 hives. I have opened them up and so far I have not been stung. Now I had a couple of beekeepers helping me look for a queen. I have not used smoke on this hive and did not this time. The interesting part we all had vales on and no other protection. I did not receive a sting, Joe got stung once and Denise got stung 3 times and had bees buzzing him the whole time. He had to put on all his protection gear on to keep from getting more stings. So I guess my question is why would on person trigger the bees sting and others don't?
