As I’ve mentioned in other posts and articles, for some time now I have been using copper tape to protect seedlings from snail and slug attack. Recently I received an email from a reader saying that he had tried it and it didn’t work. But I knew it worked well in my garden because all my seedlings were surviving even though my garden is still full of snails. But I hadn’t actually put a snail near the tape and watched what happened. So I did. The snail started to head over the copper tape, and then suddenly reared back, twisted around and made its way back down the pot. The theory is that it gives them a small ‘electric’ like shock. I was interested to see that once a snail had ventured onto the tape and received this shock, that they wouldn’t go onto the tape again. I then decided I should film it so that you could all see what happens. So I found some new snails and the rest is on the film. Thanks Dan for help with filming and editing, some bits have been sped up for effect as, well, snails can be a bit sluggish!
