I think the very best protection against slugs is copper. It won't prevent slugs in the soil inside the copper but it does prevent intruders. I have seen slugs travel over the traditional "solutions" like sand, grit, coffee, tea, etc but not yet seen any on copper.
Acrually, copper is second best. Hand picking at night works for me and I add them with fresh fruit to ice cream later. Wash them first of course
