Was the hourgalss on the back, or the belly? There is a mimicer spider that I can't remember the name of that has the hourglass on the back. Scared the hell out of me one morning...
There I was, miniding my own business, in the bathroom, relieving my bladder..... And this black spider with a red hourglass crawled across the floor in front of me. I froze, and had I not already taken care of business, I'da pissed myself. BLACK WIDOW!!!!
I'm very arachnaphobic, but my dog was in the other room, so I took my shoe and smashed it. When I calmed down, I remembered that the Black widow was supposed to have that on the belly, not readily visable on the back. So off I went to my zoology book and confirmed. Wheewh!
Anway, spray for spiders! Nasty icky horrid critters!
