Slugs do not read the script. Rough hard surfaces, grit, sand, eggshells, all suggested as deterrents do not work. If they did we would not have a slug problem in our gardens. They are survivors.
good hygiene, the occasional well spaced and covered pellet, night time vigils with a torch and salt solution, and a good habitat for birds and toads/frogs (garden pond) are the only effective protection for our plants.
