I know, I know....weird. I have been around plenty of bees in my life...same as everyone, I guess. But, I just don't seem to appear as a threat! lol I've had them land on me, fly around my head, etc...normal bee activity, but no stings. Ran around barefoot so much as a kid, I've stepped in glass, fire ants, lit cigarette butt, poop, etc... (yuck) ....yet, no bees.
I had a neighbor girl and my cat get stung by bees in my yard this year...the bees are around. Removed a paper wasp nest from a tree limb next to my deck...no stings.
My crazy, weird philosophy (honestly) is that they can chemically sense fear...pheromones, or what, I don't know. They sting whatever fears them and whatever swats them. I simply let them do what they do, and I NEVER swat them. If they land on me, I let them hang out and leave when they want...
...but no swatting. In other words, I don't piss them off in any way. It's worked so far...42 years.
