When cleaning up a big, nasty, creepy, crawly, disgusting spider off a white furry rug, whether the horrible thing is dead or alive, it WILL leave a bloody, leg spewn, crime scene like mess that requires tissue, Clorox wipes, AND a comb (for the legs, of course), for complete removal. So gross.
There.... I have done my good deed for the day and shared my wealth of knowledge on the matter, whereby sparing another from having to face the ordeal without prior instructions.
You are welcome.
Thank you honey, for cleaning it up.
