Snails and Dr Phil (I rant.)

Does any one know a home remedy for stopping snails eating my basil? I'd rather a home remedy if any one has one than pellets. I never see the snails so I can't move them to other plants. They just seem to like the basil.

( I rant. Ranty rant rant rant. Americans and stuff. Where does Dr Phil find these people? :-) )
