I posted this in pests and diseases, but not sure if anybody read it.
You can purchase copper collars to put round vulnerable plants to deter slugs, but the price is prohibitive, so I thought a cheaper alternative would be to obtain some soft copper pipe and make my own.
Get some 8mm soft copper pipe, the sort they use for small bore central heating etc, and cut it into lengths of approx 21" for 7 " diameter, or 12" for 4" diameter, form into a circle, join the ends with a bit of 6mm wooden dowel and there you have it.
Good idea Quizz, I use them to surround my runner beans when put them in, just the lengths of piping, seems to help! ;D
I wonder if heavy duty electrical wire would do the same job?
I got some self-adhesive copper tape which seemd to work.
Worth getting some copper tacks as well as tends to peel back off rough wood (especially if applied by OH).
Has anyone tried NemaSlug?

Looks a bit pricy - probably only worth it for show gardeners.
we used nemaslug on our potatoes last year, I won a prize so decided to try it..trouble is, it only works for 6 weeks so should have re applied it, didn't and got slug damage..i think it's a bit pricey if you have to use it right through the growing season :)

Any shiny copper works when the copper dulls you need to replace it. If you used wire you would need to wind it round several times to make a wider strip so the slugs can't get over it without touching it. If it is used directly on the ground rather than wrapped around a pot it will prevent the slugs on the suface crossing but there are lots underground as well some of which can get trapped inside the copper boundary if they surface there.
Thinking of how I once saw someone mend a fuse with a bit of tinfoil (not allowed and dangerous, I know!) I wonder if anyone has used tinfoil to deter slugs?
That is a very good question!
I think that copper is supposed to work because it gives slugs a bit of a shock, tinfoil does the same if you chew it and have a filling in your mouth, so I'm guessing it might? It would be a lot cheaper too!
We have used the nemaslug for several years now, and never remember the second application but it is showing a cumulative effect... fewer slugs grow up to have babies so fewer to kill....
;D
I'm going to use nemaslug on my raised beds for sure, also only used one application (expensive!) on my raised beds at home with good results. I'm tempted to do a mini trial with the tinfoil though!
deb.................do ya know of anyone offering a tin foil chewing service............?
would like to try this too............but think the oh would defo think id lost the plot if she came home and caught me chewing my way thru 6 packs of bacofoil?
Quotedeb.................do ya know of anyone offering a tin foil chewing service............?
Perhaps I could rent my dog out for this. She loves chewing foil, especially if it has had chocolate in it!

i have used copper pan scourers ( the crinkley ones) you unravel them so theres a tube ,cut a few inches off and strech it over the pot. they can be bought cheaply at discount stores as in the tape does not work so well when tarnished

This sounds and is a bit ghastly but seemed to work. If you go to a hairdressers and collect the swept up hair trimmings and put these either round the plants you are trying to protect or on the outsides of a border. Apparently slugs don't like walking over it as their trail can't slide on the hair! I tried it one year but it did look a bit strange!
The other thing - and this has probably already been suggested - spent coffee beans. Unfortunately, I can't get enough down here in Minehead as we don't have proper "coffee shops" like Starbucks or whatever!
I have tried this year seaweed in my polytunnel which I have allowed to dry, chopped up into little bits and am waiting to see what happens. The seaweed gets sharp edges and again slugs don't like it!
Good luck
;D

I definitely wouldn't reccommend trying that as the hair from a hairdressers floor will be full of all kinds of nasty chemicals & dyes. Hairdressers do not seperate the treated & untreated hair so if you use it as a mulch/slug barrier it will leach those chemicals into the ground & you will end up eating all that rubbish.

I got some copper wire from a scrap merchants - big bundle of it for about £7
I've woven it into rings (about 1/2 cm thick and 3 inches across)
Put it round my lettuces and did an 'experiment' with a couple of plants that didn't have the ring round them.
The result? The couple of plants WITHOUT the ring have disappeared with 'munch' marks round them.
I'm not ENTIRELY convinced yet though. It's been dry here so the slugs are waiting in the wings for a bit of rain to activate them!
I am also experimenting with catlitter - someone one here suggested this! Thank you for the tip ;D
The price of copper has gone UPWARDS and UPWARDS over the last few years so it's quite pricey to use this method of pest control (and have you SEEN the prices some on-line gardening sites are charging for copper collars??? OUTRAGEOUS)
I had an ingenious idea yesterday that my 1p & 2p collection (coppers!) would be able to do the job.
No such luck ::)
The copper content of pennies changed from about 95% to 5% when the price of copper went up.
HOWEVER! The pennies are copper plated (albeit to a small%) I may experiment yet again ;D
There's always a copper lining to every dark cloud!

A result Robert.
Been pondering on the use of hair clippings(male only I might add) for years.
My 'shearing shed' proprieter reckons they are compostable.
Another debate coming up?
we've used dog hair, and it works :)
I certainly vouch for the copper tape as a deterrant for slugs and snails. Tried the stuff out on hosta pots this year and its worked a treat. I would agree though the tape is a bit pricey if you ahve a lot to do and is no good for protecting border/veg plot plants. Any cheaper home made alternative is well worth a go.
Last year, I peeled the plastic wire off a piece of electrical cable and wrapped it around one of my pots. I didnt put any slug pellets on it, and didnt have any slug damage.
It's just a bit difficult getting the plastic stuff off. Watch your fingers!

Try exposing just a short bit of the wire at one end, then pulling the wire out of the plastic with pliers.
I'm a little sceptical about the copper thing !
I've tried the tapes and copper tube, and they do seem to work to a certain degree, whilst still bright and clean, but i did try an experiment with copper tacks once.
I spent a very long two hours nailing hundreds of bright copper, very sharpe tacks, into a ring of pastic.
They were spaced very close together just mm's apart, once i had done this i then subjected several of the slime critters to the task of escaping from " the ring of death" ( as it's new trade name was going to be) !!! at first they did not escape (10 mins tops) but despite the very sharpe prickly COPPER tacks they just climbed on top and made there way to freedom, i tried several modified versoins with diffrent tack spacings, but the result was always the same.
The only success i ever had, was with a Vaseline and rock salt mixture spread round the top of a dish, and all three of the slugs ( diffrent types) and one snail, refused to cross the mixture, i then made a load of it up and placed it round an old butler sink i have filled with Hostas, and it seemed to work.
so I'm a bit of a copper sceptic really.

;D ;D ;D
Well I bought some copper wire tape from Wyevale and as I was fixing it to a pot...Darn if a slug wasn't spotted *watching me*....
(Cover your eyes, here comes my sadistic bit) :o
I cut off about two inches and laid it on the wall in front of the slug. he stopped...ahem ::) I moved the slug onto the copper and he frothed and slimed (just like when you salt them). He was dead by morning from shock I think.
My beautiful hosta has a home made copper ring, Asda cheap cat litter outside of this ring, sprinkled with *Blue Sweeties* I have had no new holes since doing this. Each morning slugs and snails have passed away on the cat litter, dehydrated. ;D

Crikey you are sadistic Elle Ess. Thought i was being nasty the other day whan i decided to chuck a few snails in the pond - I took great pleasure in watching one struggle to reach a drier position!
Usualy i just dispatch them with a swift foot motion ;D. (Okay Okay, I just stamp on them!)
It was an experiment to see if it actually worked. All in the name of Horticultural Science you understand ;)

I have to confess I was thinking of doing similar, ie put a slug or snail on some copper tape to see how it reacted. Now i know but i would mind seeing for myself.
My OH is seriously thinking of replacing the hot water tank (reason too complicated to explain) so I am looking forward to having 2 large copper tubs! The old tank does not have the insulation attached to it.
Shirley I think if cut into rings the tank would be ideal. If you need smaller rings just use copper nails to secure.
Lauren :)
I love all this talk of slug killings, I have formed my own group if any of you want to join. It's called SSS Sadistic Slug Slayers and some of you sound like just what I'm looking for to join my group. 8) ;D ;D ;D ;D ;D
Gardeners World recently showed the technique of Nailing/screwing copper pipe to edge of timber raised beds(stops them getting in) after applying nematodes solution (kills what's in the soil). Pricey at first , but probably a good long term investment as it will last a years - just need to rub down with wire wool when it discolours
???
Just read somewhere else about spraying WD40 around pots and raised beds to stop slugs. Apparently it works, but would you want to eat anything liberally sprayed with it?!
