Product Information

I used the copper tape on the bottom frame of my patio door to prevent slugs from coming into the house and it is working very well. I stopped slugs getting to my potted Hosta’s by smearing a layer of Vaseline round the top edge of the pots, this works extremely well, just got to make sure the leaves don’t touch the ground or other plants ! My criticism of your comments on ‘Electrical current’ as it related to the use of copper is that it represented a deductive approach not an empirical one.

Sugar, dried yeast, flour mixed to a thin slurry in cold water – work quite well but better in drier weather. I just heard your interview on RootSimple blog and thought it was really informative and eye opening. The only thing (apart from pellets) that does work is two strips of copper with a voltage between them.Out of interest, did you try stacking two lengths of the smaller tape (so the test 4 product would result in a 5. Make sure any overhanging branches or leaves are trimmed away and do not overhang the protected area as these will act as a bridge for slugs to use. If my experiment proves non productive then I think that I might scatter some old nails around as well as the copper. The second claim is that the slime from slugs connects with the metallic copper and the slug gets a small electrical shock from it. Have developed a unit that can use existing copper tape and allows you to check if it is working with a battery life of 2 to 3 years.

Nematodes are microscopic parasitic worms that feed upon molluscs but also risk killing non-pest garden species such as water snails. I propose that the snail slime itself (with its acids) on contact with copper tape reacts with the copper alloy (IF… and that’s a big IF… it’s thick and contains enough copper alloy) to create a foul taste or suffocating effect similar to that of copper sulphate, hence the slug or snail gets a bad taste and then turns back to get a breather. I wouldn’t waste my money on copper tap because my experiment shows it could only have a very temporary effect if any. Mildly electrocuting those pesky gastropods sounds nice doesn’t it after what they’ve done to your poor plants? It makes complete sense that when the molasses was all consumed that there would be a starvation problem.If you live in a city there’s probably more chance of copper tape having this effect than if you live in the countryside. 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. Copper sulphate has been a common snail control method for a long time, it’s quite commonly used in aquatic situations where water snails have become a problem in the farming of fish[ 2] or growing rice[ 3]. HI Lee, I was thinking the same, but then reading it again I think the percentage of copper alloy is still the problem with test 4?

I used crushed oyster shell around my plants and it works as long as I cover the full area, out to the tips of the branch line, and refresh it if plant debris from overhanging plants fall onto the shells.Most products on the market are a type of copper foil or copper tape so this might work better and in fact some people suggest that a wider strip is better than a narrow strip.
