Slug damage can ruin the appearance of lush, foliage plants, flowers and vegetables. Among others, hostas , dahlias and peas are regularly eaten, which can make them difficult to grow in areas where slugs are common. While you could choose to grow a range of slug-proof plants , like rodgersia and brunnera , slugs may also be repelled from your container-grown plants if you fix copper tape to your pots. Copper tape is thin, easy to cut and simple to apply. Plus, it will gradually turn green over time, giving it an attractive aged look. Follow our step-by-step guide, below, to protecting your plants from slug damage with copper tape.
How to deter slugs with copper tape
Copper Against Slugs and Snails: Rings, Tape, Wire, Mesh | Does it work?
Does copper tape stop slugs and snails? Here’s the video evidence…
A chemical reaction happens when they crawl over the metal, which causes unpleasant feelings on their skin. Since the width of the tape seemed a bit too narrow, I glued three lines next to each other to create a 2-inch 5cm wide copper barrier. The tape barrier repelled all of the snails, and most of the slugs turned around immediately after coming into contact with the copper.
Last year I conducted some tests to disprove the value of egg shells, pistachio nut shells, hair and chilli powder in preventing slugs and snails from eating our plants, all were easily crossed by snails. Young chopped brambles were a surprise snail barrier success though. Could this somehow be why copper works as a snail barrier? Well no… but here I explain more about snails and their relationship with copper.
