    earth — which slugs don't like. It's true that diatomaceous earth will stop these critters — they are composed of silicon dioxide — basically glass — which does quite a number on these beasts. The calcium structure of eggs just isn't as effective.

  3. Diatomaceous earth is effective on insects because it absorbs the protective oils in their exoskeleton and accelerates dehydration. Perhaps that same dehydration MO works on slugs – like salt does? And slugs can slip right over broken glass, so the "sharpness" theory of eggshells is pretty laughable.
