Have to include my story.

Was trimming bushes and next thing i know i am in a cloud of
yellowjackets. I was wearing jeans, gloves, long sweatshirt and got
stung on my knows (everything else was covered). Ran for about 20
yards flailing them off until then went inside. Turns out about 20
were on my clothes and they swarmed me inside. Still waiting for
weather change before killing them.

My sister had good luck with 'Cyfluthrim Tempo 1% dust' but it is
something used by professionals.
