No Go Slug & Snail Copper Tape

No Go Slug & Snail Copper Tape Pack contains 4m. With the reduction in the use of chemicals in the garden Garland now offers a NO GO Slug & Snail Copper Tape Roll! HOW IT WORKS: When the slug or snail attempts to cross the copper tape a small electrical charge is created from the copper and the slug or snail will not cross the tape, protecting your plants from damage and without the use of chemicals. HOW TO USE: First cut the length of tape to form a complete loop of the pot or frame that is to be protected. For protection from snails as well as slugs cut V grooves all around the bottom of the tape before removing the backing tape and applying to a dry clean surface. For protection from slugs only there is no need to cut grooves, simply apply a circle of copper tape. But HOW does No Go Slug & Snail Copper Tape work (in detail)… Copper tape works as a deterrent against snails and slugs due to its ability to create a mild electric shock when the mollusk comes into contact with it. This effect occurs because copper is a conductive metal, and the slime secreted by snails and slugs contains water and dissolved salts, making it an electrolyte. When a snail touches the copper, a small electrochemical reaction takes place between the metal and the ions in the slime. This reaction generates a tiny electric current, which is enough to cause discomfort but not lethal harm to the snail. The sensation is unpleasant enough that most snails and slugs will retreat rather than continue crossing the barrier. Since copper does not degrade quickly, this method can remain effective for a long time, though oxidation or dirt accumulation may reduce its conductivity over time. Some gardeners clean the copper tape occasionally to maintain its effectiveness. Beyond the electrical aspect, copper tape may also serve as a physical deterrent due to its texture and metallic properties. Snails and slugs prefer moist, smooth surfaces and may find copper uncomfortable to traverse, further discouraging them from crossing it. Additionally, as the copper reacts with moisture in the air and the snails’ slime, it can develop a patina, which might enhance or reduce its effectiveness depending on environmental conditions. While copper tape is not a foolproof method—especially in extremely wet conditions or if snails find alternative routes—it is a widely used, chemical-free approach to protecting plants from these pests. Some gardeners enhance its efficiency by using it alongside other deterrents, such as crushed eggshells or diatomaceous earth, to create multiple layers of defense.
