How to Get Rid of Aphids on Citrosa Plant

Citrosa plants are known for their pleasant lemon scent and their ability to repel mosquitoes. However, these plants are also susceptible to aphids, which can damage the plant and affect its ability to repel mosquitoes. Aphids are small, soft-bodied insects that feed on the sap of plants. They reproduce quickly and can cause significant damage if left untreated. In this article, we will discuss how to get rid of aphids on citrosa plants.

Identify the Aphids

Before you start treating your citrosa plant for aphids, it is important to identify them correctly. Aphids are small insects that come in different colors, including green, black, brown, and yellow. They can be found on the stems, leaves, and buds of the plant. Aphids feed on the sap of the plant and can cause wilting, yellowing, and distortion of leaves. They also produce a sticky substance called honeydew that attracts ants and can lead to mold growth.

Natural Ways to Get Rid of Aphids

There are several natural ways to get rid of aphids on citrosa plants. These methods are safe for the environment and do not harm beneficial insects like ladybugs and bees.

1. Blast Them with Water

One way to get rid of aphids is by blasting them off the plant with water. Use a hose with a strong spray nozzle to spray the affected areas of the plant. Be sure to spray both the tops and undersides of leaves as aphids tend to hide there. Repeat this process every few days until all aphids are gone.

2. Use Soap Solution

Another effective way to get rid of aphids is by using a soap solution. Mix two teaspoons of dish soap with a gallon of water in a spray bottle. Spray the affected areas of the plant thoroughly, including the undersides of leaves. The soap solution will disrupt the cell membranes of the aphids, causing them to dehydrate and die.

3. Apply Neem Oil

Neem oil is a natural insecticide derived from the seeds of the neem tree. It works by disrupting the life cycle of insects, including aphids. Mix one tablespoon of neem oil with a gallon of water in a spray bottle. Spray the affected areas of the plant thoroughly, including the undersides of leaves. Repeat this process every seven to ten days until all aphids are gone.

Chemical Remedies for Aphids

If natural remedies do not work, you can use chemical remedies to get rid of aphids on citrosa plants. However, be sure to follow the instructions carefully and use protective gear like gloves and a mask.

1. Insecticidal Soap

Insecticidal soap is a type of soap that is specifically designed to kill insects like aphids. It works by suffocating the insects and disrupting their cell membranes. Follow the instructions on the label and apply it to the affected areas of the plant.

2. Pyrethrin-based Insecticides

Pyrethrin-based insecticides are derived from chrysanthemum flowers and are effective against aphids. Follow the instructions on the label and apply it to the affected areas of the plant.
