I would have broken my neck trying to jump out of the tub! I kill several spiders each week in here. I live near a large meadow and they keep crawling their way inside! I tell them that there is more to eat outside, but they don't listen.
I had one pop out from behind the shower curtain the other day. I had a bottle of Lysol shower cleaner nearby and I panicked and squirted it. Then I grabbed it up in some paper and flushed it. Still, that's not as bad as having one floating in the tub!
What is it with spiders and bathtubs?
