Product Information

Protect your plants from slugs AND snails with these new METAL versions of our best-selling Slug Collars. Available in 2 sizes,… These methods were tested on 108 lettuces sown in pots and raised beds at the RHS field research facility in Wisley. After six weeks, the leaves of each harvested lettuce were examined to calculate damage. Make sure any overhanging branches or leaves are trimmed away and do not overhang the protected area as these will act as a bridge for slugs to use.

While this research hasn’t shed any light on what you can do to obstruct slugs and snails, it has at least shown that these barriers can be unreliableand ineffective. Thanks for taking the time to research & test these – very interesting results, and I hadn’t considered the rain factor before. My older planters have 6 month old copper mesh barriers and I have yet to notice any obvious decrease in effectiveness with oxidation/dirt, but if there down the road maybe I can mitigate it with a firm wire brush scrub. It is the tiny electromagnetic charge a slug or snail feels when it tries to cross Copper Slug Tape which prevents them from reaching the plants and crops. I am not a chemist but guess it is due to some kind of ion exchange or electron donation. My guess is that something similar is taking place between the bright copper and the molluscs. Roofing metals are chosen for the job because their oxides adhere to their surface and are chemically inert under normal atmospheric condition. Knowledge of this fact is what lead me to triy the experiment in the first place.Hayley grew 108 lettuces in a series of nine patio pots and nine raised beds and monitored them for six weeks. I imagine barrier efficacy might depend on the width of the barrier and skinnier tapes might be less effective barriers than 5″ of mesh. I have yet to try using any other type of mesh (steel, aluminum) but if I get bored that might be a fun experiment. I also imagine in addition to whatever theoretical chemical/electrical property copper has that slugs don’t like, there is likely a mechanical component because irregular wire loops might be irritating to ooze across and there may be some variability in effect based on the size/configuration of the wire in the mesh.

Regardless of exactly why it works, I would recommend copper mesh to anyone with a slug problem amenable to a physical barrier who isn’t too concerned about the aesthetics. I’m so chuffed I found this piece of yours! Ha fantastic! Really appreciate the time you’ve taken on the copper tape to pass it on to everyone .How generous of you .Saving us time effort and much needed cash ..I too love anything with Monty Don and sobbed last night after watching Gardeners World to hear Nigel had passed away. Copper DOES work as a slug and snail barrier if the percentage of copper alloy is high enough and the width is in excess of 4 cms.”Copper is a known poison for many organisms and some copper chemicals are used to disinfect and kill organisms. It seems to make sense that copper tape or copper wire would have the same effect. If you think about this for a minute you will realize this can’t work. Most homes in North America use copper pipe to deliver water in our homes. If it were toxic – would we be using them? Efficacy and environmental fate of copper sulphate applied to Australian rice fields for control of the aquatic snail Isidorella newcombi

Copper sulphate is made by combining copper alloy with sulphuric acid. Whilst sulphur dioxide emissions from power stations have dropped enormously in Western Europe since the 1980s, there is still enough in the atmosphere for rain to contain traces of sulphuric acid. In certain places within the UK you will be receiving higher doses of sulphuric acid in your rain than others. What happens when this acid rain lands on copper alloy tape on your outdoor plant pots? It makes trace amounts of copper sulphate which runs down your pot and into the soil. I therefore put it to you that as the copper tape weathers, in some areas it releases traces of copper sulphate which makes it even more potent, especially on more porous terracotta pots that can hold onto the copper sulphate. If you live in a city there’s probably more chance of copper tape having this effect than if you live in the countryside. I can’t prove that it exists but it would seem logical. Serrated to provide extra protection against snails, Copper Slug Tape is a popular alternative to more chemical-based solutions.But Dr Hayley Jones, entomologist at the RHS and lead researcher, said: “With the likes of eggshells, barks and mulch so far proving no discernible deterrent to slugs and snails, we would recommend using proven formulas like nematode biological control if the damage is just too much to bear.”

As existing lab studies have shown some of the barriers work, and as other experiments by Hayley hinted that copper tape could be effective, she’s not ruling the barriers out completely. She hopes to run the study again ona different slug population and different soil type at RHS Garden, Harlow Carr in 2019. The RHS also plans to test alternative control methods, such as beer traps, and is currently working with BASF to investigate ways to combine scientifically proven control methods into pest management strategies. Help us do more research The attention to detail in this study, and the use of the leaf area meter, lets us be more precise and confident in the results." What’s next for slug and snail research? In the case of the snail we have the copper, and the electrolyte in the form of slug slime.The second electrode is missing. Also missing is the connection between the two electrodes which allows the current to flow. I don’t believe that putting slime onto copper will produce an electric charge. Does Copper Repel Slugs? The green patina developed on copper metal over time is a copper carbonate salt and could be toxic.
