Dragon fruit is a popular fruit that is known for its unique appearance and delicious taste. However, it is not immune to pests and one of the most common pests that can attack dragon fruit plants are slugs. Slugs can cause significant damage to the plant by chewing holes in the leaves and fruit, and can even kill the plant if left unchecked. In this article, we will discuss how to get rid of slugs on dragon fruit plants.

Identify Slug Infestation

The first step in controlling a slug infestation on your dragon fruit plant is to identify the problem. Signs of slug infestation include holes in the leaves, slime trails on the plant, and damaged or eaten fruit. Slugs are most active at night, so it is best to inspect your plants after dark with a flashlight.

Natural Slug Control Methods

There are several natural methods that you can use to control slugs on your dragon fruit plant:


One of the most effective methods of controlling slugs is handpicking them off the plant. This method is best done at night when slugs are most active. Use a flashlight to locate the slugs and pick them off by hand.

Beer Trap

Another effective method of controlling slugs is by using a beer trap. Simply fill a shallow dish with beer and place it near your dragon fruit plant. The smell of the beer will attract the slugs, and they will drown when they fall into the dish.

Copper Tape

Copper tape can be wrapped around the base of your dragon fruit plant or around pots to repel slugs. The tape creates a mild electric shock when slugs come into contact with it, deterring them from climbing up the plant.

Diatomaceous Earth

Diatomaceous earth is a natural substance that can be sprinkled around your dragon fruit plant to control slugs. The substance is made up of the fossilized remains of diatoms, which are microscopic aquatic organisms. When slugs come into contact with the diatomaceous earth, it dehydrates their bodies, causing them to die.

Chemical Slug Control

If natural methods don’t work, you may need to resort to chemical slug control. However, it is important to note that chemical slug control should be the last resort, as it can harm beneficial insects and other wildlife.

Iron Phosphate

Iron phosphate is a natural slug control product that is safe for use around pets and wildlife. It works by disrupting the metabolism of the slugs, causing them to stop feeding and die.


Metaldehyde is a common slug bait that can be used to control slugs. However, it is highly toxic and should not be used near pets or wildlife. It is important to follow the manufacturer’s instructions carefully when using metaldehyde.

Tips for Preventing Slug Infestations

Prevention is key when it comes to controlling slug infestations on your dragon fruit plant. Here are some tips to prevent slug infestations:

  • Keep your garden clean and free of debris
  • Remove any fallen fruit or vegetables from the ground
  • Avoid overwatering your plants
  • Use mulch around your plants to discourage slugs from laying eggs in the soil
  • Plant slug-resistant plants near your dragon fruit plant

By following these tips, you can prevent slug infestations before they start.
