Spiders and I have an understanding. As long as they're outside, there's no problem. The moment I see one inside it dies. I don't care how fast they scurry and what nooks they crawl under, they're as good as flat goo balls. I have been known to hunt one single spider for 4 hours when he got away from the first squish attempt.
He did not get away from the second
Daddy long legs are cool though. They eat other spiders and are on the "Do not kill" list.
