Watch this spider freak out
If you want to try different ways of getting rid of those nasty spiders that are in or around your house maybe you can give singing a chance. Andrew Wilcox tried this and you can tell that the spider isn't very thrilled with his singing voice. There was a study done back in 2011 that shows that spiders have thousands of tiny hairs on their body that all act as an independent ear.
