Don't get rid of them. Spiders--which are "arachnids", not "insects" (there's a big difference!)--serve a very useful function around the house and garden, by getting rid of annoying or dangerous insects that could pose threats to we humans.
Too many people have a "fear" of spiders, merely based upon their appearance, and want to "get rid of them" just for that reason alone (I doubt that they think much of our appearance either--big, soft, pink things with only four appendages!)--without considering all the good that they do for us on a daily basis.
