big yucky spider

Well, this is our spider who has made our porch her home! She looks scary, but is actually not posionous. She spins her web every morning and then it is gone at night. She has just lain a 1,000 egg sack thingy in the web, and now she is supposed to die. Only she has died yet. But when she does, I will kill the egg sack. I am not a violent person, just one who doesn't need 1,000 spiders in her home/yard/life.
