You can make a natural spider spray by getting an 8 oz bottle of peppermint or lavender soap. Put 5 Tbsp of soap per quart of water and add 5 Tbsp of any natural citrus oil.

They appear to have a lot of testimonials showing how well it works. Other than that, I would make sure I had some black ointment and X-ceptic on hand to fight the infection and draw the poisons out.
