i've been doing some de-construction (disassemble)
and i've had three types of Hornet to contend with
yellow jackets
dark brownies
and luckily no white faced hornets from hell
that see you better than all the other ones
they ALL HATE the smell of sweat
so if your wearing a sweaty ball cap
or have been sweating profusely in the hot summer sun
while out mowing
change into some dry clothes
