I did see a huge wasp today out behind the shop, it's body was easily as long or longer than my thumb. They can cause a shot of adrenalin of you think they might be coming after you. More often than not they are minding their own business, but if you give them reason to think that they are being threatened, they will aggressively respond.
So they will attack/sting humans? What is the sting like, worse than a "regular" wasp?
Ha, I remember one wasp that hit me, there was a nest low in a pine to be removed so I went there a few days before the job with a pole saw and figured I could slice off in one stroke the skinny limb it was grown around, it would hit the ground and I would run, then could sneak in later and spray the nest. I don't know how he did it but about a quarter second after I touched the limb with the pole, they attacked and got me good right on top of the dome, yeeooooowwww
