Well, you could always carry a rolled up news-paper around with you for spider smacking ... although, my Oma always said that if you squish a spider it will rain.

I guess with all the smishing you'd do, you'd have a perpetual little rain cloud following you around like something from a Douglas Adams book

I generally try to save the spiders in cups and take them outside -- i'm sure its just a chance for them to find reinforcements, and come back to the condo and camp out.
