If they eat bugs in obscure corners spiders are allowed in my house...not venomous spiders, though.Its soooooo pretty!
I'm raising a spider in my bathroom. It was the size of the pin head when I first saw it three weeks ago. I catch a small fly for it every so often. Its body is now the size of 4 pin heads. When it gets too big, I'll capture it and relocate it. But I do like watching it grow. Weird, I know.
