Gardener's nightmare

No, not a bad dream but sad reality. Every morning I go to my garden and see sunflowers without leaves, half eaten cucumbers, and I know who is guilty. Slugs!
I've tried everything... Special anty-slugs pellets, charcole, I even cooked red pepper with garlic and sprayed my plants with stinky water... Nope, slugs are not scared at all. It's not a battle any more, it's a war! Slugs, I'm kind person, so I'm warning you! You have time till tomorrow!
