The best way to get rid of slugs is to take some regular table salt and then pour some of the salt on the slug or slugs.
The salt will draw out moisture from the slugs body and dehydrate the slugs which then causes the slugs to die of dehydration.
You can also sprinkle salt around the areas the slugs crawl around on and as the slug slithers or crawls over those surfaces the slug will get salt on them which also dehydrates them.
