I read an article on slug deterants and it was found that bran is supposed to be good. You put it around the plants and the slugs don,t like to move over it. They also eat it which is supposed to blow up their tummies!?
I got a huge bag of horse bran for seven pounds. The only problem I have found is the rain you then have to reapply. Too early to say if it worked or not!
