The death knoll for slugs and snails is summed up in one word:
Osmosis.
Slugs and snails have a higher percentage of their body-weight made up of water, then other animals. Also, their skin is a much more permeable covering then average.
When you salt a slug or snail, this increases the concentration of salt on the surface (outside) of the unfortunate subject. From a different perspective, this is DECREASING the water concentration outside the slug/snail.
The process of osmosis is the movement of water from an area of high water concentration through a permeable membrane to an area of lower water concentration. The water INSIDE the slug MOVES OUTSIDE the slug, in order to reach an equilibrium concentration on both sides of the skin.
Unfortunately, this means that the slug/snail is now much drier then it can tolerate. It literally dies of dehydration.

Any little hole near the ground/foundation of the house. Even under a tile. You have to find it. Near a door or steps near a door. They like rotten old concrete that has pockets with dirt that stays damp.

It takes the water out of them so they get dehydrated and then obviously die....

slug and snails have a very lot of water in them and cannot process salt. Salt success all the water in them and die of convulcances.

salt is a dessicant, it removes water from things.

it sort of absorbs water out of their bodies through their skin... the membrane action... so, they die..
