I actually quite like the idea of the odd house spider in my place. Primarily because of all things I cannot stand flies!
Thinking about it rationally, I'd much rather have spiders than flies. (Nothing's worse than a good slug in your house though.)
Perhaps it's the behavioural patterns of spiders. If you have a housefly, you know the bugger's there because it buzzes and flies around. How often have you picked up a jumper and had a spider crawl out of it, or worse found a spider in your hair? They are creepy and also rather jumpy which probably makes us more tense. (When is it going to move?)
With that, the unappealing look of the things and those childhood cautionary tales, I think humans (with some exceptions as evidenced in this thread) simply develop a natural aversion to them.
