Oddly enough, slug chemistry is somewhat like a battery. When it comes into contact with copper, it creates a galvanic reaction similar to what happens when a fork makes contact with a filling in your mouth. And in the same way just the thought of that makes us squirm, slugs don't like it either. That's why you'll find copper tape in the lawn and garden sections of stores around here. It's a passive deterrent employed to protect plants.
