How to Get Rid of Caterpillars on Lilikoi Plant

Updated: July 10, 2023

Caterpillars can be a nuisance for gardeners, especially when they start feasting on your precious lilikoi plants. These voracious insects can quickly strip the leaves and flowers, potentially harming the overall health of your plant. However, there are several effective methods you can employ to get rid of caterpillars and protect your lilikoi plant’s vitality.

Identifying Caterpillar Infestation

Before taking action, it is vital to confirm that your lilikoi plant is indeed infested with caterpillars. Caterpillars are the larval stage of butterflies and moths, and their appearance varies widely depending on the species. However, they generally have elongated bodies with distinct segments, six true legs, and several false legs along their abdomen.

To identify caterpillar infestation on your lilikoi plant, look for the following signs:

  1. Chewed leaves: Caterpillars mainly feed on leaves, so if you notice irregular chew marks or holes on the foliage, it’s a clear indication of their presence.
  2. Fecal droppings: Caterpillars leave behind dark-colored droppings called frass. If you spot small black droppings on your plant or the ground below it, it suggests caterpillar activity.
  3. Silk threads: Some caterpillars create silk threads on the leaves or stems as they move around. These threads can help you locate the caterpillars’ hiding spots.
  4. Visible caterpillars: In some cases, you may directly see the caterpillars crawling on the plant.

Natural Remedies to Get Rid of Caterpillars

Once you’ve confirmed a caterpillar infestation on your lilikoi plant, it’s time to take action to control their population. While chemical pesticides are commonly used, they can harm beneficial insects and may not be suitable for edible plants like lilikoi. Instead, try these natural remedies that are effective and environmentally friendly:

1. Handpicking

Handpicking caterpillars is a labor-intensive but highly effective method, especially if the infestation is limited. Put on a pair of gloves and carefully inspect the entire plant, focusing on the undersides of leaves and stems. Gently remove any caterpillars you find and drop them into a bucket of soapy water to kill them. Repeat this process daily until the infestation is under control.

2. Homemade Insecticidal Soap

Insecticidal soaps can be an excellent tool to combat caterpillar infestations. To make your own, mix one tablespoon of mild liquid soap (such as castile soap) with one quart of water. Pour the solution into a spray bottle and thoroughly coat the affected leaves and stems, making sure to cover both sides. The soap suffocates the caterpillars and disrupts their feeding behavior.

3. Neem Oil Spray

Neem oil is derived from the seeds of the neem tree and acts as a natural insecticide. It has low toxicity to humans and beneficial insects but effectively repels and disrupts the life cycle of caterpillars. Mix two tablespoons of neem oil with one gallon of water and spray it onto your lilikoi plant, paying attention to the areas where caterpillars are most active.

4. Bacillus thuringiensis (Bt)

Bacillus thuringiensis, often abbreviated as Bt, is a soil-dwelling bacterium that produces proteins toxic to many caterpillar species while remaining harmless to other insects and mammals. Bt products are available in different formulations, such as sprays or powders, which can be applied directly to the lilikoi plant’s foliage following the package instructions.

5. Companion Planting

Companion planting involves interplanting certain species that naturally repel caterpillars or attract their natural predators. For instance, planting herbs like mint, sage, or basil near your lilikoi plant can deter caterpillars due to their strong aroma. Additionally, attracting birds and beneficial insects like ladybugs and lacewings by planting flowers such as marigold and daisy can help control caterpillar populations.

Preventing Future Caterpillar Infestations

Prevention is the key to avoiding future caterpillar infestations on your lilikoi plant. Here are some preventive measures you can take:

  • Regular inspection: Regularly inspect your lilikoi plant for signs of caterpillars or other pests. Early detection allows for prompt action and prevents large-scale infestations.
  • Remove weeds: Weeds near your lilikoi plant can attract pests, including caterpillars. Remove any weeds in the vicinity to reduce the chances of an infestation.
  • Prune damaged leaves: Removing damaged or infested leaves can help prevent the spread of caterpillars to healthy parts of the plant.
  • Encourage natural predators: Create a garden environment that attracts beneficial insects and birds, as they feed on caterpillars and their eggs.
  • Crop rotation: If you grow lilikoi plants annually, practice crop rotation to disrupt the life cycle of pests and reduce the risk of recurring infestations.

By employing these preventive measures and utilizing natural remedies when necessary, you can effectively manage caterpillar infestations on your lilikoi plant, ensuring its healthy growth and bountiful harvest. Remember, a balanced ecosystem in your garden is the key to keeping pests under control while promoting the overall well-being of your plants.
