Copper Slug and Snail Tape 4m sold by Boma Garden Centre

This self-adhesive copper tape creates a barrier that slugs and snails are reluctant to cross, giving them a mild static-like sensation on contact rather than harming them. It is applied around the rim of pots, raised beds or greenhouse staging to protect vulnerable plants.The roll is 4 metres long, enough to wrap several average-sized containers, and the tape can be trimmed to fit.
