That movie creeped me out too. I don't think I ever knew what kind of spider they used for it. Although, looking at them now it explains why I heartlessly kill certain pale spiders and set others free outside.
It's funny though- Avondale Spiders are Huntsman spiders. They strangle their prey to death. They don't have a webs or any of the stuff the spiders in the movie did. They are BIG though. My Dad caught a small one under a 3L empty ice cream container. That was a SMALL one. I think I was scared for life from that...
