all i can find says we only have european hornets but i don't know.
we've had them here every year i can remember and never had a problem.
they built a big nest in a dogwood tree in my back yard last year.
didn't even know it was there until the leaves fell.
relax, you worry too much about the wrong things...lol.
now those little black/yellow bumble bees that nest in the ground is something to worry about.
they will attack when you run over their nest while mowing.
