Biological treatment

Keep vegetable and flower border areas clean of waste plant materials and suitable resting areas, damp and dark, for snails daytime retreats. Place log piles and bug hotels, which snails will like to use in the day to shelter in, away from vegetable and flower border areas. Keep glasshouses and poly tunnels clean and tidy so hiding places are removed. Complete night checks with a torch and hand remove the snails. Place ground egg shell on the ground around each plant, as the snail will not like the feel of this, so should not cross it. Use horticultural grit on the soil surface around plants, as the snail will not like the feel of this, so should not cross it. On container plants place a copper band around the pot, available from most Garden Centres. The snail will not like the feel of this, so should not cross it.
