Removing debris from the property, installing copper tape, and applying diatomaceous earth or Epsom salts to affected areas are methods that help eliminate slugs. If slugs are entering the home, the entry points should be identified and focused on to ensure these treatments are effective.
Slugs typically live in wet, dark environments, such as under boards or in dense vegetation. Clean away debris on the property, particularly in areas near the home and garden, to help remove the pests. Mow the lawn often, and remove leaves and grass clippings to ensure slugs have fewer hiding places on the property.
If possible, identify the areas most affected by slugs and close any entry ways with copper tape. Copper tape can also be placed around the edging of plant containers and other garden features such as raised bed gardens to prevent the pests from eating seedlings and produce.
Diatomaceous earth is a fine powder that is used to deter a wide range of pests, including slugs. Sprinkle the diatomaceous earth in areas with noticeable slug populations, such as the damp earth near sprinkler systems, as well as generally around the gardens and around the perimeter of the home to minimize slug populations. Diatomaceous earth can also be used indoors if slugs are entering the home. Sprinkle the diatomaceous earth near entry ways and other areas where the pests have been noticed. Epsom salt is an alternative to diatomaceous earth. They are safe for garden use, too, so can be used both indoors and outdoors to minimise the slug population on the property.
