So levels of personal hygiene are better amongst cockroaches than they are amongst spiders.

I like spiders. I could never kill a spider. But then, our spiders can never deliver more than a slight nip, and they don't even usually do that. If I was in the US or Australia, I think my view of spiders would be slightly different. More along the lines of 'Eeek! It's a spider! Help! Is it going to kill me???'
