> Now, what I want to know is if there is any scientific basis on these claims. Have scientists been doing research on this!? Is there a lab somewhere where scientists are monitering sleeping patients for spider to mouth activity? Do candy companies have inspecters that choose random bits of chocolate, and dissect them for insect bits?

These are based on the annual figures of spiders which have gone missing. The only reason you don't hear more about this tragedy is that the photos their families print on the sides of milk cartons are too small for us to notice them.
