Dragon tree plants are a popular houseplant due to their striking appearance and low maintenance requirements. However, one issue that can plague dragon tree plants is the presence of lerps. Lerps are small, scale-like insects that attach themselves to the leaves of plants and feed on their sap. If left untreated, lerps can cause significant damage to the plant and even kill it. In this article, we will discuss how to get rid of lerps on dragon tree plants.

Identify Lerps on Dragon Tree Plants

The first step in getting rid of lerps on your dragon tree plant is to identify them. Lerps are small, oval-shaped insects that are about 1-2mm in size. They are usually found on the undersides of leaves and can be easily identified by the small, white, waxy sacs they create around themselves.

Remove Lerps Manually

If you only have a few lerps on your dragon tree plant, you can remove them manually. Simply use a cotton swab or a soft brush dipped in rubbing alcohol to gently wipe away the lerps and their protective sacs from the leaves. Be sure to dispose of the swab or brush after each use to prevent re-infestation.

Use Insecticidal Soap

If you have a larger infestation of lerps on your dragon tree plant, you may need to use insecticidal soap. Insecticidal soap is a low-toxicity pesticide that is effective against many types of insects, including lerps. Purchase an insecticidal soap from your local garden center and follow the instructions on the label.

To use insecticidal soap on your dragon tree plant, first, make sure the plant is well-watered and not in direct sunlight. Spray the plant thoroughly with the insecticidal soap, making sure to cover both the tops and bottoms of the leaves. Wait for the soap to dry before rinsing the plant off with plain water.

Apply Neem Oil

Another effective way to get rid of lerps on your dragon tree plant is to apply neem oil. Neem oil is a natural insecticide that is derived from the neem tree. It works by disrupting the life cycle of insects and preventing them from reproducing.

To use neem oil on your dragon tree plant, mix 1-2 tablespoons of neem oil with a gallon of water in a spray bottle. Spray the plant thoroughly, making sure to cover both the tops and bottoms of the leaves. Repeat this process every 7-10 days until the lerps are gone.
