I think it's odd that I'm saying this, but I'd vote to move it safely to another location. (I do NOT like spiders) These spiders aren't going to jump and attack you the moment you get near.

If it where a rattlesnake would you kill it and dispose of it? It'd be a lot more difficult for me to move that, but I'd find a way to do that too. (even if it meant calling someone more able to accomplish it)
