Control slugs and snails by deterring them, rather than killing them, by this effective copper adhesive tape. Simply surround the rims of pots or tubs with our copper barrier tape.
Should our slimy enemy try and cross the copper tape barrier, it gives off a safe but unpleasant electric shock to them, so they turn tail and 'run' away! It sounds odd, but it works very well, they simply refuse to cross it.
Lasts for years, so it can be left on all year round.
