Updated: February 2, 2023

Citronella mosquito plants are known for their ability to repel mosquitoes due to their strong fragrance. However, caterpillars can sometimes invade these plants and cause damage to the leaves and stems. In this article, we’ll discuss how to get rid of caterpillars on citronella mosquito plants.

Identifying Caterpillars on Citronella Mosquito Plants

Before we dive into how to get rid of caterpillars, it’s important to identify them first. There are several types of caterpillars that can infest citronella mosquito plants, including:

  • Armyworms
  • Cutworms
  • Cabbage loopers
  • Hornworms

These caterpillars vary in size and appearance. However, they all have one thing in common – they can cause significant damage to the citronella mosquito plant.

How Caterpillars Damage Citronella Mosquito Plants

Caterpillars feed on the leaves and stems of citronella mosquito plants, which can cause significant damage. They can eat large holes in the leaves, strip the leaves entirely, or even cut through the stem. This damage weakens the plant and makes it more susceptible to other pests and diseases.

How to Get Rid of Caterpillars on Citronella Mosquito Plant

There are several methods you can use to get rid of caterpillars on citronella mosquito plants. Here are some of the most effective methods:

Handpicking

One of the easiest ways to get rid of caterpillars is to handpick them off the plant. Wear gloves and inspect the plant for any signs of caterpillar infestation. Once you have found a caterpillar, gently pick it off the plant and dispose of it in a bucket of soapy water.

Neem Oil

Neem oil is a natural insecticide that is effective against caterpillars. Mix one tablespoon of neem oil with one gallon of water and spray it on the citronella mosquito plant. Make sure to spray the leaves and stems thoroughly, as caterpillars can hide in hard-to-reach places.

Bacillus Thuringiensis

Bacillus thuringiensis (Bt) is a bacteria that is toxic to caterpillars. It is available in powder or liquid form and can be applied directly to the citronella mosquito plant. Mix the Bt according to the instructions on the package and spray it on the leaves and stems of the plant.

Insecticidal Soap

Insecticidal soap is another natural insecticide that is effective against caterpillars. Mix one tablespoon of insecticidal soap with one gallon of water and spray it on the citronella mosquito plant. Make sure to cover all parts of the plant, including the undersides of the leaves.
