EVG 20mm x 25m Copper Slug Tape | Adhesive Copper Slug Snail Repellent | Slug Deterrent Barrier Tape | Humane Pest Control

Product Information

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 As with any copper material, Copper Slug Tape will turn green with age, but will not affect the product’s performance.

You may be correct. As I said I am not a chemist. Although I’m not sure that ‘Conducting current’ is the same as ‘exchanging an electrical charge’. But who really cares. The issue is whether or not it works and if so, under what conditions. The most humane way to get rid of slugs? Hayley said: “Collect the slugs by hand - the best time to catch them is at night, and either release them at a local wood or pop them in your freezer before binning them Thanks for taking the time to research & test these – very interesting results, and I hadn’t considered the rain factor before. 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? 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.”Some products may be delivered straight to your door from one of our suppliers and these products will be labelled within the product description. 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. According to the RHS, some slug species have clear benefits for gardeners, such as the leopard slug, which eats fungi and rotting material, helping recycle garden nutrients. 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.

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.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. 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?

Protect your plants from slugs AND snails with these new METAL versions of our best-selling Slug Collars. Available in 2 sizes,…Of the thousands of enquiries received by RHS Gardening Advice every year, deterring slugs and snails is atop concern. To ensure we aregiving the best advice on this much-debated topic, we set up a project – Gastropod Barriers– to test whether the most commonly recommended home remedies really work. How we tested the barriers

So pleased, daren’t put anything outside, especially with all the rain we’ve had without the tape. We tried it last year for the first time and it really did work. Thanks again. If I go out at night I will usually see 2-3 slugs oozing circles around the bottom of the barrier but not crossing it. I have seen a slug or two successfully cross it, but it’s rare. If I had to guess I would say I get about 1/20th -1/200th the slug prevalence I used to previously high slug traffic areas I have since “protected”. (tough to say because I am too lazy to count, and I can’t tell how many slugs crossed the barrier vs just live on the other side) 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. Clearly you like Teh Science so here’s a data base of studies for inverts. http://www.pesticideinfo.org/List_AquireAcuteSum.jsp?Rec_Id

But wool pellets and pine bark did have one clear benefit: by acting as a fertiliser and mulch, they helped lettuces yield a 50% bigger crop.
