Catnip is a plant that is known for its ability to attract cats. The plant has a pleasant aroma that stimulates cats, and it is often used as a natural remedy for anxiety and insomnia in felines. However, catnip plants can be infested with pests known as lerps. These small, white, cotton-like insects attach themselves to the leaves and stems of the plant and can cause damage if left untreated. In this article, we will discuss how to get rid of lerps on catnip plants.

What are Lerps?

Lerps are small insects that belong to the family Psyllidae. They are commonly found on citrus trees, eucalyptus, and other plants. Lerps attach themselves to the leaves and stems of the plant and create a protective cocoon around themselves made of sugar and wax. This cocoon protects them from predators and insecticides.

Signs of Lerp Infestation

The signs of lerp infestation on catnip plants include:

  • Small, white, cotton-like insects attached to the leaves and stems of the plant
  • Sticky residue on the leaves
  • Stunted growth
  • Wilting leaves

If you notice any of these signs on your catnip plant, it is likely that your plant is infested with lerps.

Getting Rid of Lerps

There are several ways to get rid of lerps on catnip plants. Here are some methods you can try:

Method 1: Pruning

One way to get rid of lerps on catnip plants is by pruning the affected leaves and stems. Use a pair of clean scissors or pruning shears to cut off the affected parts of the plant. Be sure to dispose of the cuttings away from the plant to prevent re-infestation.

Method 2: Natural Predators

Another way to get rid of lerps on catnip plants is by introducing natural predators. Ladybugs and lacewings are natural predators of lerps and can help control their population. You can purchase these insects at your local garden center and release them onto your catnip plant.

Method 3: Insecticidal Soap

Insecticidal soap is a safe and effective way to get rid of lerps on catnip plants. You can purchase insecticidal soap at your local garden center or make your own by mixing 2 tablespoons of dish soap with 1 gallon of water. Spray the solution onto the affected parts of the plant, making sure to cover both the top and bottom of the leaves.

Preventing Lerp Infestation

  • Keep your plant healthy by providing it with adequate water, sunlight, and nutrients.
  • Inspect your plant regularly for signs of infestation.
  • Prune any affected leaves and stems immediately to prevent the infestation from spreading.
