No spider "urine": Spiders don't actually urinate. They produce near-solid uric acid which combines with digestive wastes to be eliminated through the anus. Studies have not revealed bacteria in their excrements. There is a Latin American myth that spiders can urinate on a person who is sleeping leading to skin ulceration. There is no scientific evidence to back up this claim.
