For some reason the wording of this website bothers me... Yes, they do mention that they are 'beneficial' insects, but still.
I suppose it's not inaccurate - some folks are deadly allergic and Africanized strains can be very aggresive.

To whit: I had a pissed off bee follow me into the shop today. Would NOT leave me alone. Finally I decided to quit shooing it away (I suppose I was frozen with panic) and just sat there while the bee settled on my arm and began to LICK me.

They are dangerous I tell ya!!!
