Product Description Slug Gone wool pellets make a highly effective barrier against slugs and snails. Derived from British wool and suitable for organic gardens, you simply lay the pellets on growing media around the stems of plants, and then wet them. Once wetted they self felt to form a continuous mat around the stems. Minute fibres in the mat are an irritant to slugs and the mat also absorbs moisture from the slug s foot. As an organic material, Slug Gone contains naturally occurring nutrients and will help feed plants. The pelleted mat also improves moisture retention. Slug Gone is Soil Association approved, and safe to use where children and pets have access.
