Doug..wasps,hornets,i guess i was just using the wrong name as we just call them yellow jackets and they can be nasty.
i still have a bite mark on my hand where a bald face got me when i was taking photos of mushrooms on a canoe trip last year,i must of got too close to the nest.
i know bug spray is nasty stuff but the way i look at it in the last five years i have only used it twice in my yard.if i was hosing down every wasp/hornet that comes around i would be knee deep in empty cans.....
