I hardly encounter bees in need. Usually I run away from them as I did earlier this year while hiking through LAOS mountains. They were just coming after me. Oh could have been wasps.
Last year on a camping I had wasp attack at my camper. I did run again, and when returning after a few hours, I saw at least 100 wasps in a half filled glass with apple juice, all drowned. Couldn't help them anymore.
