wood ashes and similar materials placed around plants provide some protection. However, moisture reduces the effect of these treatments.
Salt also is toxic to slugs and direct applications of table salt to a slug can kill it. This technique has limited usefulness because excessive salt can affect plants. Certain metal ions also are highly repellent to slugs. Barriers of copper foil exclude slugs from greenhouse benches and raised bed plantings. Other copper-based materials, such as copper sulfate, repel slugs.

Tell him to stop feeding them, then you wont get so many. Make sure you don't leave any food scraps out at night and keep areas prone to dampness as clean and dry as possible. Killing them with salt IS cruel, regardless of how simple the sentience of a slug may be they can still feel pain. If you have to dispose of them, the method of letting them fall into tins filled with beer or similar mentioned above is certainly more humane.

Osmosis of the water from inside the slug in an attempt to dilute the salt and equalize the concentrations on both sides of the membrane (in this case, the skin).

Similar reason as to why you don't drink salt water. The salt concentration would be higher in your digestive system than it would be in the blood, so water will get pulled out of your system in an attempt to equalize the salt concentrations.

Their skin is porous compared to ours. When you pour salt on them they shrivel up and dehydrate due to osmosis.

It essentially sucks the moisture out of them.
