Chris, someone once told me that wasps are the least aggressive of all the bees, if that is any consolation for you. However, Tonya seems to have more information than I do.

I once had an infestation of those huge black bumblebees in my living room. They got into the house in a tiny opening behind my bookcases near the fireplace. I thought I was going to die........ There were dozens of them - all buzzing like jet planes.
