USA Girl --
Despite your concern, I love to find creative ways to KILL yellow jackets. They are aggressive, unwelcome co-inhabitants of the biome.
Personally, I prefer fire, poison and suffocation.
I put them in the same class as roaches in terms of value.
and BTW, they don't have the cranial capacity to understand a human emotion like 'suffering.'
Kinda hard to have any cranial capacity when you don't even have a cranium.
