Corn plants are a popular houseplant that adds a touch of greenery and beauty to any home. However, they are susceptible to infestations from pests such as lerps. Lerps are tiny insects that create a waxy, protective shell around themselves to protect them from predators. These pests can damage the leaves of your corn plant, making it look unsightly and reducing its ability to photosynthesize. Fortunately, there are several ways to get rid of lerps on your corn plant.

Identifying Lerps on Corn Plant

Before you can get rid of lerps on your corn plant, you need to identify them. Lerps are small, sap-sucking insects that measure less than 1mm in length. They look like small bumps or blisters on the leaves of your corn plant and are usually found on the undersides of the leaves. If you suspect that your corn plant has a lerp infestation, turn the leaves over and look for small, white or yellowish bumps.

Getting Rid of Lerps on Corn Plant

There are several ways to get rid of lerps on your corn plant. Here are a few methods that you can try:

1. Use a Sticky Trap

Sticky traps are an effective way to catch lerps and prevent them from spreading to other plants in your home. You can purchase sticky traps at most garden centers or online retailers. Simply place the trap near your corn plant and wait for the lerps to stick to it.

2. Use Insecticidal Soap

Insecticidal soap is a natural insecticide that is safe for plants and pets. It works by suffocating the lerps and preventing them from feeding on your corn plant. To use insecticidal soap, dilute it according to the instructions on the label and spray it directly onto the affected leaves of your corn plant. Repeat the process every few days until the infestation is gone.

3. Remove Infested Leaves

If your corn plant has a severe lerp infestation, you may need to remove the affected leaves to prevent the lerps from spreading to other parts of the plant. Use a pair of clean, sharp scissors to cut off the infested leaves and dispose of them in a sealed plastic bag. Be sure to wash your hands thoroughly after handling infested leaves.

4. Use Neem Oil

Neem oil is a natural insecticide that is effective against lerps and other pests. To use neem oil, mix it with water according to the instructions on the label and spray it directly onto the affected leaves of your corn plant. Repeat the process every few days until the infestation is gone.

  • Water your corn plant regularly but avoid overwatering
  • Keep your corn plant out of direct sunlight
