Copper Slug Tape Multibuy 3 x 4m rolls

Product Information

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. WEATHER-PROOF: Single-use copper barrier tape: apply to greenhouse poles, pots, raised beds, cold frames and planters. Lasts through all weathers As members of the Mollusca group of animals, slugs and snails use Hemocyanin proteins in their blood to transport oxygen around their bodies ( whereas we mammals use iron based Hemoglobin). These Hemocyanin proteins contain two copper atoms. This makes all molluscs very sensitive to the ingestion of additional quantities of copper. Too much copper and it prevents oxygen from moving around their bodies and they eventually die, unless they flee to safety. Could be working for the other two but seeing as they managed to eat this one I'm guessing they just haven't attempted the other two yet... Regardless of the use of copper strips or electricity, some types of slugs have been know to drop down from overhanging trees or even lower themselves down a slime trail.

Jeff Gillman, one of the Garden Professors, commented “When I’ve tested copper the slugs seemed to have a slight preference for not crossing it, but would if that was what they need to do to get where they were going. I’d call it a mild repellant” . I think this is a good summary. Slugs will not go out of their way to cross copper in tape form, but it is not a fool proof solution.I’ve tested solid copper rings which I made from some spare copper roofing strip. Did it work? Yes and No; the difference is oxidation. 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.

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. 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?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.

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 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) 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.” If you’re using any of these five home remedies to deter slugs and snails, consider carefully whether they are making enough difference to be worth the investment. 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.Don’t want to kill slugs, just deter them. Someone suggested mint leaves-dry. He/she didn’t know if it worked when wet. I don’t believe in killing slugs–whenever man invades Nature by killing off it’s creatures, it creates an imbalance somewhere else (as we have SLOWLY learned). Man (and other people) are the worst environmental stewards.
