How to Get Rid of Lerps on Fig Tree Plant

Updated: June 5, 2022

If you have a fig tree plant, you may have encountered the small, white, waxy insects known as lerps. These pests can cause damage to the plant and make it difficult for it to produce fruit. Fortunately, there are several ways to get rid of lerps on your fig tree plant.

What are Lerps?

Lerps are small insects that infest fig trees. They create a white, waxy coating over themselves as they feed on the sap of the plant. This coating protects them from natural predators and pesticides, making them difficult to control. Lerps can cause damage to the plant by reducing its ability to photosynthesize and produce fruit.

Identify the Infestation

Before treating an infestation, it’s important to make sure that your fig tree actually has lerps. One way to identify an infestation is by looking for the white, waxy coating on the leaves or branches of the tree. You may also notice small, brown bumps on the leaves or branches that could be eggs or nymphs.

Treatments for Lerps on Fig Tree Plants

There are several treatments that can be used to get rid of lerps on your fig tree plant:

Manual Removal

The first step in getting rid of lerps is to remove them manually. You can do this by gently scraping off the white, waxy coating with a soft-bristled brush or your fingers. Be careful not to damage the leaves or branches while doing this. Once you’ve removed as many lerps as possible, dispose of them in a sealed container.

Neem Oil

Neem oil is a natural pesticide that can help control lerps on your fig tree plant. Mix one tablespoon of neem oil with one gallon of water and spray it on the affected areas of your plant. Be sure to spray both sides of the leaves and the branches. Repeat this treatment every seven to 14 days until the infestation is gone.

Insecticidal Soap

Insecticidal soap is another natural pesticide that can be used to control lerps on your fig tree plant. Mix two tablespoons of insecticidal soap with one gallon of water and spray it on the affected areas of your plant. Be sure to spray both sides of the leaves and the branches. Repeat this treatment every seven to 14 days until the infestation is gone.

Prevention

The best way to prevent a lerp infestation is to keep your fig tree healthy. Make sure it is getting enough water and nutrients, and prune it regularly to remove any dead or diseased branches. You can also use a horticultural oil spray in the spring to suffocate any overwintering pests.
