Dwarf oyster plants are a great addition to any garden or indoor space. They are low-maintenance and have an interesting leaf shape that resembles a small oyster shell. Unfortunately, they are also a favorite food of slugs. These slimy pests can quickly destroy your plants if left unchecked. In this article, we will discuss some effective methods for getting rid of slugs on dwarf oyster plants.

Identify Slug Damage

Before we discuss how to get rid of slugs, it’s important to know what damage they cause. Slugs feed on the leaves of dwarf oyster plants, leaving behind ragged holes and slimy trails. If you notice these signs, it’s likely that slugs are present.

Remove Debris

Slugs love to hide in debris such as fallen leaves and twigs. Removing this debris from around your dwarf oyster plants can reduce the number of slugs in the area. Be sure to dispose of the debris away from your garden to prevent slugs from returning.

Handpick Slugs

One effective but time-consuming method for getting rid of slugs is handpicking them. Go out at night with a flashlight and pick off any slugs you find on your dwarf oyster plants. Be sure to dispose of them far away from your garden.

Use Slug Traps

Slug traps are another effective way to reduce the number of slugs in your garden. You can buy slug traps or make your own by placing shallow dishes filled with beer around your dwarf oyster plants. The slugs will be attracted to the beer and drown in the dish.

Use Copper Tape

Copper tape is a natural slug repellent that can be wrapped around the base of your dwarf oyster plants. When slugs come into contact with the copper, they receive a small electric shock that deters them from climbing up the plant.

Apply Diatomaceous Earth

Diatomaceous earth is a natural powder made from the fossilized remains of tiny aquatic organisms. When slugs come into contact with it, it dehydrates and kills them. Sprinkle diatomaceous earth around the base of your dwarf oyster plants to deter slugs.

Use Slug-Resistant Plants

If you’re tired of dealing with slugs altogether, consider planting slug-resistant plants near your dwarf oyster plants. Plants such as lavender, rosemary, and thyme are known to repel slugs.


Slugs can quickly destroy your dwarf oyster plants if left unchecked. By removing debris, handpicking slugs, using slug traps, applying copper tape, and using diatomaceous earth, you can effectively get rid of these pests. Planting slug-resistant plants can also prevent future infestations.
