Oh for real, that is also something to legitimately freak out about!! I did so over a black widow once that was on the ceiling. If it had been in a blanket, I might have died.
One year we were inundated with grasshoppers - it was biblical, and limited to a few block radius that included my building. I would come home and there would be one on my front doorknob.
So one day I'm out there flinging mail at it yelling for it to fuck off and die, and my neighbor comes out and scares it off for me. Because I am that loud too. LOL
