I'm terrified of spiders as well. My standard response to encountering one is to scream like a four-year old girl and run away.(And I'm a 37-year old man, so it can be funny to watch) That being said, we have similar issues with shrubs in our front yard(Lots of spiders and webs), and I don't do anything about them. Despite how I feel about them, I know that those spiders keep a lot of other bugs under control. In fact, I wish the backyard had more spiders, since the bugs can be really annoying out there. They aren't going to hurt you, and you should think of them as natural pest control.(Which is really what they are) Yes, it can be annoying, particularly at night, but killing them would be pointless, since others will just move into the now-vacant prime real estate.
