Slugs and snails damage may be reduced by changing how you water. Since they require damp ground cutting back on watering when possible can reduce their numbers. It is common for landscapes to be over watered. Most plants in most growing conditions do not need to be watered daily or even every other day.
Some other types of control:

Beer or a mix of honey or molasses with bakers yeast placed in container. I think this works best if placed in a bottle that is then placed at an angle to reduce the chance of rain or sprinklers diluting the mixture. These will need to be checked often because of evaporation.

Iron phosphate slug baits work very well and are not harmful to people, pets, birds, or wildlife. Sluggo and Escar-Go! are a couple brands I have used.  continued
