Ugh... Yellow Jackets. When I was younger about 25 years ago, I was maybe 12 or 13, I was camping with my parents along the Susquehanna River, and I got stung by ONE while riding my bike, and I went into Anaphalactic shock about a half hour later. I got to ride in an ambulance and get a shot of benedryl and a shot of epinephrine at the hospital. I was worthless the rest of the day. My body was jello from one or both of those meds. I had to carry an epipen everywhere after that and go through 5 years of immunotherapy (injected live bee venom).
I agree... Kill them with whatever means necessary.
