Ficus Rubber plants are a popular houseplant due to their attractive appearance and easy maintenance. However, they are prone to infestation by pests such as lerps. These tiny insects can cause damage to the plant’s leaves and reduce its overall health. In this article, we will discuss how to get rid of lerps on Ficus Rubber plants.

What are Lerps?

Lerps are tiny insects that belong to the family of psyllids. They attach themselves to the underside of leaves and secrete a sugary substance that forms a protective cover called a “lerp”. The lerps provide shelter for the insects and their eggs, making it challenging to get rid of them.

Signs of Lerps Infestation

The first sign of lerps infestation is the appearance of small, brownish bumps on the underside of the leaves. These bumps are the lerps themselves. As these bumps grow, they can cause discoloration and eventually lead to leaf drop.

How to Get Rid of Lerps

Step 1: Remove Infested Leaves

The first step in getting rid of lerps is to remove any infested leaves. Use a pair of scissors or pruning shears to cut off the affected leaves entirely. Be sure to dispose of these leaves carefully to prevent spreading the infestation.

Step 2: Wash the Plant

Once you have removed the infested leaves, it’s time to wash the plant thoroughly. Use a gentle stream of water from a hose or showerhead to rinse off any remaining lerps or lerps’ residue from the plant’s leaves and stems.

Step 3: Apply Insecticidal Soap

Insecticidal soap is an effective way to get rid of lerps without harming your Ficus Rubber plant. Make sure to follow the instructions on the label and apply the soap evenly to the plant’s leaves and stems.

Step 4: Repeat Treatment

Repeat the insecticidal soap treatment every seven days for two to three weeks or until you no longer see any signs of lerps on your plant. It’s essential to be consistent with your treatment to ensure that all the lerps are eliminated.

Preventing Lerps Infestation

Prevention is always better than cure when it comes to pests. Here are some tips to prevent a lerps infestation on your Ficus Rubber plant:

  • Keep your plant healthy by providing it with sufficient water, light, and nutrients.
  • Regularly inspect your plant for signs of pests and remove any infested leaves immediately.
  • Quarantine any new plants before introducing them to your Ficus Rubber plant.
  • Use sticky traps to catch any flying insects that may be attracted to your plant.


Can I use rubbing alcohol to get rid of lerps?

Rubbing alcohol may be effective in killing lerps, but it can also damage your plant’s leaves if used excessively. We recommend using insecticidal soap instead.

Are lerps harmful to humans?

No, lerps are not harmful to humans. They only feed on plants and do not pose a threat to humans or pets.

How do I know if my Ficus Rubber plant is healthy?

A healthy Ficus Rubber plant should have bright green leaves without any spots or discoloration. It should also have a full, bushy appearance, indicating that it’s growing well.

In conclusion, getting rid of lerps on your Ficus Rubber plant requires patience and persistence. By following the steps outlined in this article, you can eliminate these pesky insects and keep your plant healthy and beautiful. Remember to take preventative measures to avoid future infestations.
