I seem to have a problem with Yellow Sac Spiders in my apartment. Has anyone dealt with these little buggers? I have always lived on upper floors and never seen them before. They leave really nasty welts and are common in Michigan. Fortunately my cats are great at finding them, however, I still seem to get a bite ever few days.

Does anyone have experience getting rid of them, preferably natural. I have two cats. If I have to, I will move them for a day.

Thanks!
