Watching slugs and snails move around a bowl - contender for the most boring youtube video you've ever watched.
We stock Copper Tape at Agile Home and Garden, and one of the questions I 'm always asked is does it really work against slugs and snails? Today, we'll be putting it to the test!
I've used copper tape to stop slugs and snails for years, and I've always sworn by it - however, a quick google search will throw up tonnes of conflicting results. It seems some people love it and some people think it's rubbish.
But how is it supposed to even work? The truth is no one really knows, but there's a whole bunch of theories.
I've read people say the edge of the copper tape is too sharp for them to travel over, I've heard people say the copper causes a chemical reaction in their slime, or even that the copper causes a minute electrical current to flow via their slime. Whatever the true mechanisms behind it, copper has been used by gardeners to deter and repel slugs and snails for decades. But does it really work?
In our tests we lined the inside of a bowl with copper tape, and put slugs inside to see if they could escape, and to see what their reaction to the copper was.
The slugs and snails were captured in our garden and released afterwards - no slugs or snails were harmed during the making of this programme!
Though this exercise was by no means a scientific experiment, for me it confirmed my belief that copper is an effective, (if not 100% effective) tool to deter slugs and snails.

Fascinating experiment 10 out of 10.

@aldosigmann419 2 года назад

You needed to give them a path out as well - give them a choice and see if they take it. If it's just all copper then they may just 'force' themselves over it however painful... Also with age the copper oxidizes and develops a greenish patina - i wonder if it gets neutralized then...

Bruh, its like watching a soccer game.

Nice experiment. I have just placed a 6cm band around some pots after some beans got destroyed - fingers crossed. The positive gradient of the inside of the bowl might help the slugs a little due to more favourable gravity. Normally the tape is on the outside and the slug has to work harder against gravity and has to spend slightly more time on the copper. I imagine having a rim before the copper could help as an obsticle could slow them down so they have to spend more time on the copper so more chance they give up rather than the slug trying to sprint across. For an enhanced experiment you could also include some lettuce leaves within slug sniffing distance.

I was thinking the same thing about the outward slope of most pots presenting a more challenging obstacle. Lifting their bodies over the tape stuck to the surface, especially the tape’s slick surface reduces their ability to remain stuck to it.

@kristinajendesen7111 Месяц назад

I put a band of serrated copper tape, serrations pointing down, around the stems of vulnerable plants like young sunflowers. It has worked every time. I missed putting some on a plant support so they bypassed the copper on that and completely nommed another young sunflower. The other ones are untouched though.

If you have metal dental work and you’ve accidentally chewed on a bit of aluminum foil, you may have experienced a nasty shock. In this scenario your saliva acts as an electrolyte allowing electricity to flow from one metal to the other creating the equivalent of a battery in your mouth. Apparently snails are a good source of iron, so I wonder if their slimy bodies are acting as an electrolyte allowing electricity to flow between the metals, and shocking them in the process. I have absolutely no proof of this, but that will be my guess. That may also explain why some snails can endure the potentially uncomfortable experience for a period of time...just like you could continue chewing on that aluminum foil until it was too uncomfortable to handle.

Great vid, ive tried over 10 methods now. The worst being wd 40 and vaseline.. theh love the stuff extra lubricant to cross. Im sure i must have been trolled! Going ro try this next as don't want to use pellets which kill other garden life!

@Aetila 3 года назад

My idea: Make 2 lines of copper tapes close to each other...and connect them to a battery, one to the + the other to the -...so they will short it and receive some DC current, but only when they try to cross over. :-)

@jordandale85 3 года назад

Clearly not concerned about the bugs, I like it.

@davidbale5954 16 дней назад

This works using a battery. Single copper tapes do not work.

@smithy1928 Год назад

I feel like because they have literally no where else to go, eventually they'll go over the copper line. The bigger ones figured that out quicker. So I think outside it could be more effective in turning them around and heading off the other way

@thedarkknight1971 9 месяцев назад

Stick 2 strips of copper with a centimetre gap between all the way around whatever pot, planter, raised bed, whatever... then, attach a 9v battery to them, the positive to one strip, the negative to the other strip... They WONT EVER cross that line! You just have to check the tape is secure and unbroken and the battery still has charge occasionally. The other way of doing it is, same setup with tape, but, have a solar battery pack (taken from old/knackered LED lights) and wire the positive and negative to the separate strips, this way you'll always have a charged battery, and thus always have an electric barrier to protect from those slimy plant eating buggers! 👌👍😉 😎🇬🇧

@Eeda01 2 месяца назад

But copper oxidizes really quickly

@thedarkknight1971 2 месяца назад

@@Eeda01 Yeah, it does, but, voltage can still be transmitted between the + & - strips, especially when a snail or slug travels over them. Also using copper strips was just one suggestion, aluminium foil tape strips could be another way, as long as a circuit can be made with snail/slug slime... 😏👍

Because it is copper tape can you connect a wire from tape to a battery would the tape carry the current please?

@kokeskokeskokes Год назад

If you are cheapo like me, paint the strip with epoxy, led it cure enough until it is sticky and swirl the pot in salt.

@Biggerbadwolf 11 месяцев назад

How about a double band, with a small battery connected across them? I think that would provide a very strong discouragement!!

@lelexu739 Год назад

Good

@-1-2-1- Год назад

I understood its the toxic verdigris that causes them pain. Worth testing an oxidised copper strip.

@derpmarine216 3 года назад

The actual reason copper tape can be effective is you can use it on combination with a 9v battery to shock them. There are a lot of youtube videos that show you how to do it, but it’s very effective and you only need to replace the battery around once a year.

@CornPopWazABadDude 2 года назад

Wrong, the copper alone creates a shock to them with out any current ran into it due to their body make up. Some just go right through it like a person could go over an electric fence if it wasn't too strong, it'd just be uncomfortable.

@kovalskibethyname Год назад

you need copper with +2 oxidation state for this to work

@buckaroobonzai2909 10 месяцев назад

I think the copper has to be polished. It works because the chemical makeup of the slug has a chemical reaction and hurts the slug. I think. Similar to how soapy water dissolves the fatty/waxy armor chitin in beetles, so if you spray them, they die, since soap binds with their skin.

Does the copper oxidize over time and need reapplying?

@buckaroobonzai2909 10 месяцев назад

I have researched and worked with metals here and there in my life a bit and I say yes. The copper turns green like the statue of liberty and fails to work in the same way you need to polish a brass knob in order for it to keep killing viruses.(yes. Polished brass kills them.) The same way a car battery positive terminal will get corrosion buildup and need brushed off or the starter will get no battery energy.
