We have very large spiders in our house, I let them stay because
1. They are funny to watch--we are on the ninth or tenth generation in our shower in the master bathroom -- they get all territorial and do those spider pushups when water splashes on their webs.
2. We have black widows, brown recluses (arizona browns), scorpions, and other nasties here, and the spiders like to eat at least some of them. And they love to eat the few mosquitos, and many gnats that make their way into our house!
3. They are the mundane symbol of the Navajo goddess Changing Woman and I feel kind of weird about randomly killing them when I live in the very southern end of their (the Navajos') former range. It seems like sacrilege (OK, I'm strange, I admit it).
I do wipe away part of their webs when it gets out of control, when I feel like our house starts to look like a Halloween funhouse out comes the duster
