How to Get Rid of Lerps on Mandevilla Teepee Plant

If you have a Mandevilla teepee plant in your garden or home, you may have encountered a common problem: lerps. Lerps are small, flat, disc-shaped structures that attach themselves to the leaves of plants, including the beautiful Mandevilla teepee plant. These tiny pests can cause damage to your plant if left untreated. In this article, we will discuss what lerps are, why they are harmful to Mandevilla teepee plants, and most importantly, how to get rid of them.

What are Lerps?

Lerps are protective coverings created by small insects called psyllids. Psyllids feed on the sap of plants and then excrete a sugary substance known as honeydew. This honeydew is sticky and can attract ants, fungi, and other pests. The psyllids use the lerps as a shield to protect themselves from predators and harsh environmental conditions.

Why are Lerps Harmful to Mandevilla Teepee Plants?

Lerps may seem harmless at first glance, but they can actually cause significant damage to your Mandevilla teepee plant. Here are a few reasons why they are harmful:

1. Reduced Photosynthesis

Lerps cover the surface of the leaves, blocking sunlight and reducing the plant’s ability to carry out photosynthesis. Photosynthesis is vital for a plant’s growth and overall health. Without enough sunlight, the plant may become weakened and struggle to produce energy.

2. Weakened Plant Structure

As psyllids continue to feed on the sap of the Mandevilla teepee plant, they weaken its structure. This can lead to stunted growth and make the plant more susceptible to diseases and other pests.

3. Infestation Spread

If left untreated, lerps can attract other pests and diseases. Ants, in particular, are known to be attracted to the honeydew produced by psyllids. Ants can then protect these pests from natural predators and help them spread to other parts of the plant or even to nearby plants.

How to Get Rid of Lerps on Mandevilla Teepee Plants

Now that we understand the potential harm caused by lerps, let’s explore some effective methods for getting rid of them:

1. Manual Removal

One of the simplest ways to get rid of lerps is by manually removing them from your Mandevilla teepee plant. You can gently scrape off the lerps using a soft brush or your fingers. Be careful not to damage the leaves or stems of the plant while doing this.

2. Pruning Infected Areas

If the infestation is severe, you may need to consider pruning off the heavily infected areas of the plant. Make sure to use clean and sharp pruning tools to minimize any further damage. Remember to dispose of the trimmed branches properly to prevent the spread of pests and diseases.

3. Natural Predators

Introducing natural predators can be an effective method for controlling lerp infestations. Ladybugs, lacewings, and parasitic wasps are known to feed on psyllids and their eggs. You can attract these beneficial insects to your garden by planting flowers such as daisies, marigolds, and fennel.

4. Insecticidal Soap

Insecticidal soap is a safe and effective option for controlling lerps on Mandevilla teepee plants. It works by suffocating the insects without harming the plant or beneficial insects. Follow the instructions on the product label and apply the soap directly onto the lerps and affected areas of the plant.

5. Neem Oil

Neem oil is another organic option for controlling lerps. It has insecticidal properties and can disrupt the feeding and reproduction of psyllids. Mix the neem oil with water according to the instructions on the label and spray it onto the plant, focusing on the lerps and affected areas.

6. Systemic Insecticides

If other methods fail to control the lerp infestation, you may consider using systemic insecticides. These insecticides are absorbed by the plant and circulate through its tissues, making them effective against hidden pests like lerps. However, it is important to read and follow the instructions carefully to ensure the safety of both the plant and the environment.

Prevention is Key

Preventing lerp infestations is always better than dealing with them after they occur. Here are a few preventive measures you can take:

• Regularly inspect your Mandevilla teepee plant for any signs of pests or diseases.
• Keep your plants healthy by providing adequate sunlight, water, and nutrients.
• Avoid over-fertilizing, as excessive nitrogen can attract psyllids.
• Remove any weeds or debris around your plants that may harbor pests.
• Consider using a reflective mulch around your plants to deter psyllids.

In conclusion, lerps can be a nuisance for Mandevilla teepee plant owners, but with proper care and attention, they can be effectively controlled. By following the methods mentioned in this article, you can ensure the health and beauty of your Mandevilla teepee plant while keeping pesky lerps at bay.
