Why does everyone seem to hate wasps ?
You are far more likely to be stung by flailing your arms around, trying to swat them, than by just leaving them alone. They soon fly away.
My worst experience was when one landed on my top lip and started to crawl up my left nostril. I knew trying to brush it away would probably lead to my being stung, so I kept trying to snort it out. Eventually, it flew away.
I have never been stung by a wasp and only ever once by a bee - when I tried to pick one up when I was about 8
