This copper foil tape protects my plants very well from slugs. I just make some rings around the base of the plant so they don't get in. It's important to make more than one ring around the stem of the plant as this band is fairly short (1/2 inch). Slugs don't seem REALLY deterred by just one copper ring, so having several to crawl around increases the potency of the copper significantly. The copper itself is very thin, which may or may not be good for you. . Basically, it's as thin as paper and just as easy to wrinkle. I'm not sure I'll ever buy this again because I need a wider width to keep snails off my plants but I think overall it's a very good product.
