Prune low branches or trees or shrubs which touch the ground. Rake the leaves or mulch in order to allow the ground to dry. Metaldehyde or mesurol bait can be used to kill slugs. Read the label carefully. Do not allow pellets to come in contact with leaves of vegetables.
Empty cans buried up to the lip and partially filled with beer can be effective slug traps.
Beer should be changed every few days to remain effective. Barriers of diatomaceous earth, wood ash, lime, sawdust, copper striping, and salt embedded plastic strips can be used around bedded plants. Some of these tactics are more effective than others. Barriers of diatomaceous earth, sawdust, wood ash, and lime may need to be replaced after each rain. Do not use barriers of salt, this can damage your soil.
