How do you keep slugs?

salt is probably the most gruesome and effective method of killing slugs without getting your hands dirty, yet im guessing that your intending on keeping them out of your vegetable garden in which case salt would be an inappropriate method. your best bet is to go to your local garden centre and buy some slug pellets but if your into economical solutions, you can always crush up egg shells into shards and sprinkle them around your plants so that the shards of shell discourage them as they dont want to crawl over sharp things.
