Anti-slug barrier gel, 1000ml: Extremely effective & long-term protection for your garden, easy to use

Don‘t give snails a chance: The Anti-Snail Barrier Gel creates a physical barrier that is insurmountable for snails. As soon as they come into contact with the gel, they lose interest in crossing, as the special texture of the gel deters them. The result is reliable protection that saves your flowers, vegetable beds and ornamental plants from nocturnal attacks by slugs and snails. You can sit back and relax again and enjoy the full splendor of your garden without having to worry constantly about feeding damage.
