Hornets and bees are related about the same as
horses and cattle. You wouldn't blame horses in general because a bull chased
you out of the pasture. Hornets don't make honey. They are nasty
tempered. They just happen to be yellow and black and their sting hurts a LOT
more than a bee's.
Bait and poison. Spray the holes
with wasp spray. There's a reason they don't call it bee spray
:)
