If you use laundry powder instead of the salt, the snails squeal as well.
But it is not going to be good for your garden to be adding salt to the
soil. It has been said that you can spray the snails with coffee and it
will kill them. I haven't tried it. Perhaps a pinch of instant coffee
sprinkled onto slugs will finish them off? An instant caffine hit might
turn them into frentic hyperslugs, burning themselves out in minutes?

The iron-based snail pellets are supposed to be safe, and don't fall
apart so quickly in wet weather like the old types seem to.
