The Cat’s Pajamas plant, also known as the Catmint plant, is a beloved herbaceous perennial that produces beautiful lavender-blue flowers. However, like any plant, it can fall prey to pests and diseases. One of the most common issues that Cat’s Pajamas plant owners face is worms infestation.

Worms can cause severe damage to your plant, leading to yellowing leaves, stunted growth, and even death. Fortunately, there are several ways to get rid of worms in your Cat’s Pajamas plant.

Identify the Worms

Before you can take any steps towards getting rid of the worms, you need to identify them. There are several types of worms that can infest the Cat’s Pajamas plant, including:

  • Cutworms: These are grey or brown caterpillars that curl up when disturbed.
  • Loopers: These are green caterpillars that move in a looping motion.
  • Armyworms: These are green or brown caterpillars that move in large groups.
  • Webworms: These are white caterpillars that spin webs around leaves.

Natural Remedies

If you want to get rid of worms in your Cat’s Pajamas plant without using chemicals, there are several natural remedies you can try:


The most straightforward way to get rid of worms is by handpicking them off your plant. Wear gloves and carefully pick off any visible worms you see on your Cat’s Pajamas plant.

Neem Oil

Neem oil is a natural insecticide that can repel and kill worms. Mix two tablespoons of neem oil with one gallon of water and spray on your plant. Repeat every two weeks until the worms are gone.

Diatomaceous Earth

Diatomaceous earth is a powder made from the fossilized remains of marine phytoplankton. It can kill worms by dehydrating their bodies. Sprinkle diatomaceous earth on your Cat’s Pajamas plant and the soil around it.

Companion Planting

Companion planting involves planting certain plants next to each other to repel pests. Planting garlic, onions, or chives near your Cat’s Pajamas plant can help repel worms.

Chemical Remedies

If natural remedies don’t work or the infestation is severe, you may need to resort to chemical remedies. Here are some options:

Insecticidal Soap

Insecticidal soap is a low-toxicity insecticide that can kill worms without harming your plant. Mix one tablespoon of insecticidal soap with one gallon of water and spray your Cat’s Pajamas plant.

Bacillus Thuringiensis

Bacillus thuringiensis is a bacterium that produces toxins that are deadly to worms. Mix one teaspoon of Bacillus thuringiensis with one gallon of water and spray your plant.

Preventive Measures

Preventing worms from infesting your Cat’s Pajamas plant is the best way to avoid having to deal with them in the first place. Here are some preventive measures you can take:

  • Keep your garden clean and free of debris.
  • Water your plant at soil level to avoid wetting the leaves.
