yes they do sting till the carcas gets hard even if you barely bump them.
ive checked everywhere but in side the eves and i cant really get to there i do have a big vent in the front that had nests from years past tons of them i cleaned them all out and replaced the screen. went around the house already the wife is scared to death of them.
my house is two story so i have to get way up on a ladder and spray them with wasp killer and they do not like that chit at all.
and immediately dive bomb your ass.

im not using any sprays to stop them or anything inside just diligence with my cropping scissors and im collecting the stingers for someone i dont really like.heheheheh
