Oh man, I read about something similar last year and maybe even the year before! So I TOTALLY wash the heck out of my grapes every time now.
Eeeeeek!!
Hope this discourages all the people who engage in supermarket pilfering. It’s because of them, not spiders, that I already thoroughly wash my grapes.
If you want a reason to wash grapes, work in a produce store. After spending an hour packaging them your hands smell like matches (from the sulfur).
Oh nooooo… you have expanded my spider phobia to the produce aisle. 
Produce store…bananas…weird tropical bugs/spiders coming out of the boxes.
I haven’t seen it happen in years (maybe it has to do with them being gassed locally, dunno), but it used to be pretty common to open a box of bananas and have something crawl out of it.
Hey, let’s not start another Grape War.
I never wash my grapes. Who cares if the black widow that bites me is clean or not?

This is why I always pay up for shucked corn.
Wash? I think I will be using a flamethrower now.
But if I wash my grapes, that’ll mess up the subtle interplay of flavors arising from the pesticides that the connoisseurs at Monsanto and/or Archer Daniels Midland spent all day slaving over a hot beaker formulating for me. Although I have gotten to the point in my life where creating my own recipes has become interesting. Maybe I should wash my grapes so I can turn right around and dunk them in my own special pesticide mix. They might not taste as good, but I’m sure I’ll improve given some time.
