I have a method of stopping them eating your plants which is 100% effective! but won't work when it's wet, so it does have a down side.
Go to a horse feed dealer and buy a sack of bran. You can get it from a supermarket but you will pay dearly for it wheras you can get a 20kg sack of it for about £7! imagine how long that would last.
Just sprinkle a good amount around your plant, I sprinkle a ring around my dahlias, when the slugs try to cross it they are dehydrated immediately and in the morning you will find loads and loads of them just sitting on the bran. When I had Koi, I used to feed the slugs to them.
You could bury some sort of guttering pipe into the ground around the edges of your beds, you would just have to scrap out the old wet bran when it rains and replace it. It really does work!!!!!!!!!
