How to Get Rid of Scales on Citrosa Plant

Updated: August 10, 2022

Citrosa plants are wonderful additions to any home garden, providing a pleasant aroma and natural pest repellent properties. These plants are often grown for their ability to repel mosquitoes, but they can also be prone to infestations of pest insects like scales.

Scales are small pests that attach themselves to the leaves, stems, and branches of plants, sucking the sap out of them and causing damage. If left untreated, scales can cause stunted growth, yellowing leaves, and even death in severe cases. Fortunately, there are several ways to get rid of scales on your citrosa plant.

Identify the Type of Scale

Before you begin treatment, it is important to identify the type of scale affecting your plant. There are two main types of scales: armored and soft. Armored scales have a hard outer shell that protects them from predators and insecticides, while soft scales have a soft outer covering that makes them more vulnerable.

To identify the type of scale on your citrosa plant, look for small bumps or raised areas on the leaves and stems. If you see a hard, brown or black shell covering the bump, it is likely an armored scale. If you see a softer, lighter colored bump without a hard outer shell, it is likely a soft scale.

Use Natural Remedies

One of the easiest ways to get rid of scales on your citrosa plant is by using natural remedies. Here are some effective natural remedies:

  • Neem oil: Neem oil is a natural pesticide that can kill scales on contact. Mix 1-2 tablespoons of neem oil with 1 gallon of water and spray the solution directly onto the affected areas.
  • Dish soap: Mix 1 tablespoon of dish soap with 1 quart of water and spray the solution onto the affected areas. The soap will suffocate the scales and help to remove their protective coating.
  • Rubbing alcohol: Mix 1 part rubbing alcohol with 2 parts water and spray the solution onto the affected areas. The alcohol will kill the scales on contact.

Use Chemical Insecticides

If natural remedies are not effective, you may need to use chemical insecticides to get rid of scales on your citrosa plant. Here are some effective chemical insecticides:

  • Horticultural oil: Horticultural oil is a type of insecticide that suffocates scales by blocking their breathing pores. Follow the instructions on the label carefully when applying horticultural oil.
  • Insecticidal soap: Insecticidal soap is a type of insecticide that works by breaking down the protective coating of scales, causing them to dehydrate and die. Follow the instructions on the label carefully when applying insecticidal soap.
  • Systemic insecticides: Systemic insecticides are absorbed into the plant and can kill scales from within. Follow the instructions on the label carefully when applying systemic insecticides.
