I would think a barrier method would be good – like egg shells.

so the next time that you boils eggs, save the shells. crack them up into chunky pieces and then scatter the shells around the garden. it will stop the snails from crawling in as they don’t like the feeling of crawling on the shells. plus it is a free method to get rid of the snails and it is also chemical free.

You need a blue tongue lizard they love snails

You need a blue tongue lizard to eat your snails.

I have just bought the new thing (rich grow) that u sprinkle around the base and then water in …seems to be doing the trick heaps of new growth,(so far anyway) plus I only have to do it every 6 weeks. Fingers crossed. Thanku so much for the great help mums

Beer? Really? And was it effective?

I know this will sound strange but my dad use to spray them once a week with full strength beer

I pick up most of the snails by hand. Using gloves of course! And they I put some rock salt at the base of the plants affected by snails. Sometimes if functions, sometimes not.
I used pellets in the past, but now that I’ve got a dog, I don’t feel so safe about it.

Most effective snail treatments are in pellet form. I agree that pyrethrum is worth a shot, its actually derived from a daisy flower, its not specific for snails but does treat a wide range of garden pests. There is also a spray called Yates Confidor that is very effective BUT there is a withholding time after you treat with Confidor before you can pick any fruit and veges again. I know for citrus, its 3 weeks, so no good to use if you have fruit ready for picking in that time. Using crushed up egg shells liberally around the base of the plant and trellis posts may help prevent snails climbing on to the plant because snails and slugs don’t like crawling over the sharp edges of the egg shells. You can fill a dish with beer and leave near the plant, the snails are attracted to it and drown, just make sure the sides of the dish are vertical so they can’t climb out and replenish every few days to make sure its deep enough. Coffee grounds will repel but not necessarily kill (especially the larger ones). And one final one, gathering by hand will reduce the numbers – lots of fun if you have little boys especially – dispose of them by dunking in soapy water and wrapping in a plastic bag, or put your foot on them. Good luck.

Spray the leaves with pyrethrum – the snails should ingest this through their skin as they crawl over it.

Not sure – maybe some mesh around the leaves and maybe some eggshells on the ground.

The only thing I can think of is to sprinkle sawdust or coffee grounds at the base of the plant to stop the snails from climbing the plant.
