How to Get Rid of Caterpillars on Citrus Plant

Caterpillars are a common pest that can cause significant damage to citrus plants. They feed on the leaves, flowers, and fruits, leaving behind unsightly holes and creating a pathway for other pests and diseases to attack the plant. If you notice caterpillars on your citrus plant, it’s important to take action quickly to prevent further damage. In this article, we will discuss various methods to get rid of caterpillars on citrus plants.

Identify the Type of Caterpillar

Before taking any action, it’s crucial to identify the type of caterpillar that is infesting your citrus plant. Different types of caterpillars require different methods of eradication, and some caterpillars may even be beneficial to your plant. Some of the most common caterpillars that attack citrus plants include:

• Citrus swallowtail caterpillars: These caterpillars are large, green, and black with orange spots. They have a distinctive horn on their back end and feed on the leaves of citrus plants.
• Orange dog caterpillars: These caterpillars are bright orange with black stripes and have a distinctive horn on their back end. They feed on the leaves of citrus plants.
• Leafrollers: These caterpillars roll up the leaves of citrus plants and feed inside the rolled-up leaves.

Natural Methods to Get Rid of Caterpillars

There are several natural methods to get rid of caterpillars on citrus plants. These methods are non-toxic and safe for the environment.

Handpicking

The easiest method to remove caterpillars from your citrus plant is by handpicking them. Wear gloves and carefully pluck the caterpillars off the plant and dispose of them in a bucket of soapy water. This method is particularly effective for small infestations.

Neem Oil

Neem oil is a natural insecticide that is effective against caterpillars. Mix two tablespoons of neem oil with a gallon of water and spray the solution onto the affected areas of your citrus plant. Repeat this process every seven to 14 days until the infestation is under control.

Bacillus Thuringiensis

Bacillus thuringiensis (Bt) is a naturally occurring bacteria that is toxic to caterpillars but harmless to humans, pets, and beneficial insects. Mix one tablespoon of Bt with a gallon of water and spray the solution onto your citrus plant. Repeat this every seven days until the infestation is under control.

Chemical Methods to Get Rid of Caterpillars

If natural methods are not effective in controlling the caterpillar infestation, chemical methods may be necessary. However, it’s important to use chemicals as a last resort and to follow the instructions carefully.

Insecticidal Soap

Insecticidal soap is a low-toxicity pesticide that works by suffocating caterpillars. Spray the soap directly onto the affected areas of your citrus plant, making sure to cover both the tops and bottoms of the leaves. Repeat this process every seven to 14 days until the infestation is under control.

Pyrethrin

Pyrethrin is a natural insecticide that is derived from chrysanthemum flowers. It works by attacking the nervous system of caterpillars, causing them to become paralyzed and eventually die. Pyrethrin is available in both liquid and dust formulations and should be applied according to the manufacturer’s instructions.
