How to Get Rid of Lerps on Citrus Twist Plant

If you’ve noticed a white, cottony substance on your citrus twist plant’s leaves, stems, or fruit, it’s likely that you have a lerp infestation. Lerps are the protective coverings that insects called psyllids secrete over themselves for protection. These pests suck the sap from the plant and can cause stunted growth, yellowing leaves, and premature fruit drop. However, there are steps you can take to get rid of lerps on your citrus twist plant.

Identify the Problem

Before you can take any action to get rid of lerps, you need to make sure that what you’re seeing is indeed a lerp infestation. Look for small, brownish bumps on the leaves, stems, and fruit of your citrus twist plant. If you see these bumps moving around or notice a sticky honeydew substance on the leaves or fruit, you likely have a psyllid infestation.

Remove Infested Areas

The first step in getting rid of lerps is to remove any heavily infested areas from your citrus twist plant. Use pruning shears to cut off any branches or leaves that have a lot of lerps on them. Be sure to dispose of these infested plant parts in a sealed plastic bag to prevent the psyllids from spreading.

Wash the Plant

Next, wash your citrus twist plant thoroughly with a strong stream of water. This will help dislodge any remaining lerps and their honeydew residue. You may also want to use an insecticidal soap spray to further clean the plant and kill any remaining psyllids.

Introduce Natural Predators

There are several natural predators that feed on psyllids and can help control their population on your citrus twist plant. Ladybugs and lacewings are two examples of beneficial insects that eat psyllids. You can purchase these predators from a garden center or online and release them onto your citrus twist plant.

Apply Neem Oil

Neem oil is a natural insecticide that is effective in controlling psyllid infestations. Mix neem oil with water according to the package instructions and spray it onto your citrus twist plant. Be sure to cover both the tops and undersides of the leaves, as well as the stems and fruit.

Monitor Your Plant

After taking these steps to get rid of lerps on your citrus twist plant, continue to monitor it closely for any signs of reinfestation. Check the plant regularly for any brown bumps or sticky residue on the leaves or fruit. If you notice any new infestations, take action immediately to prevent the psyllids from spreading.

FAQ

Can I use chemical insecticides to get rid of lerps on my citrus twist plant?

While chemical insecticides may be effective in controlling psyllids, they can also harm beneficial insects and pollinators. It’s best to try natural methods first, such as introducing natural predators or using neem oil.

How often should I wash my citrus twist plant to prevent lerp infestations?

Regularly washing your citrus twist plant with a strong stream of water can help prevent psyllid infestations. Consider washing your plant once a week during the growing season, especially if you notice any signs of honeydew residue on the leaves or fruit.

Can I eat fruit from a citrus twist plant that has had a lerp infestation?

While lerps themselves are not harmful to humans, their honeydew residue can attract ants and other pests. It’s best to avoid eating fruit from a citrus twist plant that has had a severe lerp infestation.
