I used to use salt but it took the slugs a long time to die. Found a faster method was white vinegar sprayed or poured on slug. Also keep several wide mouthed jars with lids and one inch of white vinegar (plus a stick beside each jar) around the yard. Great for when you overturn a rock or pail, or old wood, etc and find anything from a fat 2 inch slug to a tiny baby slug snoozing. Whatever the size they stopped moving immediately upon hitting the vinegar. The vinegar even flushes out centipedes if poured on damp rocky areas. Downside to pouring on ground is it also kills worms which I need for my chickens. Whether hunting at dawn and dusk or coming upon them accidentally during daytime, at least I do not worry about the bees or praying mantis that also populate the garden. Happy slug hunting folks! P.S vinegar is great used directly on centipede or mosquito bites.
