How to Get Rid of Caterpillars on Catmint Plant

Catmint plants are popular among gardeners due to their attractive foliage and beautiful flowers. However, these plants are susceptible to caterpillar infestations that can cause significant damage. Caterpillars are the larvae of moths and butterflies and can chew on the leaves, flowers, and stems of your catmint plant. Here is a guide on how to get rid of caterpillars on your catmint plant.

Identify the Caterpillar

Before you begin treatment, it’s essential to identify the type of caterpillar infesting your catmint plant. Different caterpillars respond differently to treatments, so it’s vital to take note of the species. Some common caterpillars that infest catmint plants include:

• Cabbage loopers
• Armyworms
• Cutworms
• Tent caterpillars

If you’re not sure about the caterpillar species, take a sample to your local garden center for identification.

Handpicking

One effective way to get rid of caterpillars on your catmint plant is handpicking them. This method is ideal if you have a small infestation. Inspect your plant daily and pick off any visible caterpillars by hand. You can also use a pair of scissors to snip off the affected parts of the plant.

Use Insecticidal Soap

Insecticidal soap is an effective way to get rid of caterpillars on your catmint plant. The soap works by suffocating the caterpillars, causing them to die. To use insecticidal soap, mix it with water according to the manufacturer’s instructions and spray it on your plant. Be sure to cover all parts of the plant, including the undersides of leaves.

Apply Bacillus Thuringiensis (BT)

Bacillus Thuringiensis (BT) is a natural bacteria that is toxic to caterpillars. It works by producing a protein that causes the caterpillar’s gut to dissolve, leading to death. You can purchase BT in the form of powder or liquid and apply it to your catmint plant. Follow the manufacturer’s instructions for application.

Neem Oil

Neem oil is an organic insecticide that is effective against caterpillars. It works by disrupting the caterpillar’s hormone system, leading to death. To use neem oil, mix it with water according to the manufacturer’s instructions and spray it on your catmint plant. Be sure to cover all parts of the plant.

FAQ

Caterpillars love hiding in debris, so make sure you clean up fallen leaves and other plant debris regularly. You can also use row covers to prevent adult moths and butterflies from laying eggs on your catmint plant.

Can I use chemical insecticides to get rid of caterpillars?

Chemical insecticides can be effective against caterpillars, but they can also harm beneficial insects like bees and butterflies. It’s best to use organic methods like handpicking, insecticidal soap, BT, or neem oil.

Most caterpillars are harmless to humans, but some species can cause skin irritation or allergic reactions. It’s best to wear gloves when handling caterpillars.

In conclusion, caterpillar infestations can cause significant damage to your catmint plant if left unchecked. Handpicking, insecticidal soap, BT, and neem oil are effective ways to get rid of caterpillars on your catmint plant. Remember to identify the species of caterpillar before treatment and take preventive measures like keeping your garden clean to prevent future infestations.
