How to Get Rid of Lerps on Christmas Plant

Updated: March 25, 2022

Christmas plants, also known as poinsettias, are a popular decoration during the holiday season. However, they can be vulnerable to pests such as lerps. Lerps are small, flat insects that attach themselves to the leaves and stems of the plant. They secrete a sticky substance that can attract other insects and cause damage to the plant. If left untreated, lerps can weaken and eventually kill the plant. Here are some tips on how to get rid of lerps on your Christmas plant.

Identify the Problem

Before attempting to treat lerps, it is important to identify them correctly. Lerps are small, brown insects that resemble tiny discs. They attach themselves to the leaves and stems of the plant and secrete a sticky substance that can attract other insects. You may also notice yellowing or wilting leaves on your plant if it has a lerp infestation.

Remove Lerps Manually

One way to get rid of lerps is to remove them manually. This can be done by gently wiping them off the plant with a damp cotton ball or cloth. Be sure to dispose of any lerps you remove in a sealed bag or container to prevent them from returning to the plant.

Use Insecticidal Soap

Another effective way to get rid of lerps is to use an insecticidal soap. These soaps are made from natural ingredients and are safe for use on plants. They work by suffocating the lerps and other insects that may be present on the plant. Follow the instructions on the packaging carefully and apply the soap evenly to all parts of the plant.

Prune Infested Areas

If your Christmas plant has a severe lerp infestation, you may need to prune away some of the affected areas. Use clean, sharp pruning shears to remove any stems or leaves that are heavily infested with lerps. Be sure to disinfect your pruning shears after use to prevent spreading the infestation to other plants.

Maintain Good Plant Care Practices

Prevention is always better than cure when it comes to plant pests. To prevent lerps from infesting your Christmas plant, maintain good plant care practices. This includes providing the plant with adequate water and nutrients, keeping it in a well-lit area away from drafts, and avoiding over-fertilizing.


Lerps can be a frustrating problem for Christmas plant owners, but with the right treatment methods, they can be eliminated. By identifying the problem, removing lerps manually, using insecticidal soap, pruning infested areas, and maintaining good plant care practices, you can keep your Christmas plant healthy and beautiful throughout the holiday season.


Are lerps harmful to humans?

No, lerps are not harmful to humans. However, their sticky secretions can attract other insects that may bite or sting.

Can I use chemical pesticides to get rid of lerps?

While chemical pesticides may be effective in getting rid of lerps, they can also harm beneficial insects such as bees and butterflies. It is recommended to use natural methods such as insecticidal soap first before resorting to chemical pesticides.

How often should I apply insecticidal soap to my Christmas plant?

Follow the instructions on the packaging carefully for best results. In general, it is recommended to apply insecticidal soap every 7-10 days until the infestation is eliminated.
