To be honest that is not a very big spider. When i was a teen i saw a Wolf spider that was sitting in a sink that was about the size of a child's fist. It was grey, hairy, and it's front mandibles was about the size of this spider's legs. Still remember it's multiple eyes looking at me. I didn't bother it though, left it alone to do it's thing. If it's that big it has been doing it's job extremely well, probably eating grasshoppers or something. I only kill spiders if they become aggressive, had a black widow looking spider that had it out for me one time and it met the bottom of my shoe, probably wasn't a Black Widow but it kept jumping and charging at me so it met it's maker.
