Most Common Lipstick Plant Pests:
Identification and Treatment Guide

Lipstick plants (Aeschynanthus spp.) are popular houseplants known for their vibrant red or pink tubular flowers that resemble a tube of lipstick. These tropical plants are native to the rainforests of Southeast Asia and are relatively easy to care for, making them a favorite among plant enthusiasts.

However, like any other houseplant, lipstick plants are not immune to pests. In this article, we will discuss some of the most common pests that can infest lipstick plants, how to identify them, and effective treatment methods.

Aphids

Aphids are tiny insects that feed on the sap of plants. They are usually found on the undersides of leaves and can multiply rapidly if not controlled. Signs of aphid infestation include distorted leaves, sticky residue on the plant’s surface (known as honeydew), and the presence of ants, which feed on the honeydew.

To treat an aphid infestation on your lipstick plant, start by gently wiping off the affected leaves with a damp cloth to remove any visible aphids. Then, mix a mild soapy water solution (1 teaspoon of liquid dish soap per 1 liter of water) and spray it onto the plant, focusing on the undersides of leaves where aphids tend to gather. Repeat this treatment every few days until the infestation is under control.

Mealybugs

Mealybugs are another common pest that can cause damage to lipstick plants. These small insects are covered in a white, cotton-like substance and usually congregate in clusters along leaf joints, stems, and other hidden areas of the plant. Signs of mealybug infestation include stunted growth, yellowing leaves, and a sticky residue on the plant’s surface.

To get rid of mealybugs on your lipstick plant, you can use a similar approach as with aphids. Start by manually removing the visible mealybugs with a cotton swab dipped in rubbing alcohol or a mixture of water and dish soap. Then, spray the entire plant with a solution of 70% isopropyl alcohol and water (1 part alcohol to 3 parts water), making sure to coat all affected areas. Repeat this treatment every few days until the infestation is eliminated.

Spider Mites

Spider mites are tiny pests that are difficult to see with the naked eye. They are common in dry indoor environments and can cause significant damage to lipstick plants if left untreated. Signs of spider mite infestation include speckled leaves, webbing between leaves and stems, and overall plant decline.

To treat spider mites on your lipstick plant, first, isolate the plant from other houseplants to prevent the infestation from spreading. Then, thoroughly rinse the plant under a gentle stream of lukewarm water, focusing on the undersides of leaves where spider mites tend to hide. After rinsing, wipe down the leaves with a damp cloth to remove any remaining mites. To further control the infestation, you can use a commercial insecticidal soap or neem oil spray. Follow the instructions on the product label for application frequency and dosage.

Scale Insects

Scale insects are small, immobile pests that attach themselves to plant stems and leaves, sucking out the sap and weakening the plant. They are often mistaken for small bumps or lumps on the plant’s surface. Signs of scale insect infestation include yellowing leaves, sticky residue, and black sooty mold growth.

To remove scale insects from your lipstick plant, start by scraping them off gently with a toothbrush or your fingernail. Be careful not to damage the plant while doing so. Afterward, wipe down the affected areas with a damp cloth to remove any remaining scales. To prevent further infestation, you can apply a horticultural oil spray or insecticidal soap following the product instructions.

Fungus Gnats

Fungus gnats are small, mosquito-like insects that are attracted to damp soil. While they do not directly harm lipstick plants, their larvae can feed on the plant’s roots, leading to root damage and stunted growth. Signs of fungus gnat infestation include adult gnats flying around the plant and small black flies emerging from the soil when disturbed.

To control fungus gnats in your lipstick plant, start by allowing the soil to dry out between waterings. This will help disrupt the gnat’s breeding cycle. You can also place yellow sticky traps near the plant to catch adult gnats. If the infestation persists, you may need to repot the plant in fresh, sterile soil to eliminate any remaining larvae.

Prevention is Key

While it is essential to know how to identify and treat common pests that can infest lipstick plants, prevention is always better than cure. Here are some tips to prevent pest infestations:

• Regularly inspect your plants for signs of pests and take immediate action if detected.
• Keep your lipstick plants healthy by providing them with proper lighting, watering, and humidity levels.
• Avoid overwatering your plants, as damp soil can attract pests like fungus gnats.
• Quarantine new plants before introducing them to your existing collection to prevent the spread of pests.
• Clean and sterilize gardening tools regularly to avoid transferring pests from one plant to another.

By following these preventive measures and promptly addressing any pest issues, you can keep your lipstick plants thriving and free from infestations.

In conclusion, while lipstick plants are generally easy to care for, they are not exempt from pest problems. By being vigilant and knowing how to identify and treat common pests such as aphids, mealybugs, spider mites, scale insects, and fungus gnats, you can ensure the health and beauty of your lipstick plants. Remember, prevention is key, so don’t forget to implement preventive measures to avoid pest infestations in the first place.
