Just found this it made me chuckle:
Copper coins: Rubbish. The slugs just walk over them.
Eggshell: Useless. The slugs just stride straight past.
Small traps filled with cheap beer. Semi-effective. But although they catch a lot of slugs there are still more slugs that they didn?t catch. I also now have a lot of Tesco value 2% lager hanging around the place. It tastes like bad shandy. Any takers?
Slug pellets. These were the ones that are harmless to animals and pets. I think they may be harmless to slugs too. One snail did get caught.
Stamping on them. Effective if you can devote your life to watching your plants on a 24 hour-a-day basis.
The latest plan is to put the few surviving plants on a plastic table. The top of the legs of the table have been coated in WD40 household oil, thereby meaning that any slugs who climb up get to a certain level and then fall to their deaths from a great height. I shall report back. Any slugs who want these plants are going to have to resort to James Bond-like antics. Which they probably will.
