Most Common Paper Plant Pests:
Identification and Treatment Guide

Updated: July 15, 2023

Paper plants, also known as houseplants, are a popular choice for many people to bring some greenery into their homes. They not only add beauty and aesthetic appeal but also provide several health benefits by purifying the air and improving humidity levels. However, just like any other plant, paper plants are susceptible to pests that can affect their growth and overall health.

Identifying and treating common paper plant pests is essential to ensure the well-being of your indoor plants. In this article, we will discuss some of the most common pests that infest paper plants and provide a comprehensive guide on how to identify and treat these pesky invaders.

Aphids

Aphids are small, pear-shaped insects that feed on the sap of plants. They can be found in various colors, including green, yellow, black, or brown. These pests reproduce quickly, causing damage to the leaves and stems of paper plants.

Identification: Aphids can be identified by their small size (approximately 1/8 inch), soft bodies, and long antennae. They are often found in clusters on new growth or underneath leaves.

Treatment: The first step in treating aphids is to remove them physically by spraying the infected plant with a strong stream of water. You can also use insecticidal soap or horticultural oil to control the infestation. For severe cases, introducing natural predators like ladybugs can help eliminate aphids from your paper plants.

Spider Mites

Spider mites are tiny arachnids that feed on the sap of plants, causing yellowing leaves, webbing, and stunted growth. These pests are known for their ability to reproduce rapidly in warm and dry conditions.

Identification: Spider mites can be difficult to spot due to their small size (less than 1/20 inch). However, you may notice fine webbing on the underside of leaves, yellow or speckled leaves, and tiny moving dots.

Treatment: To treat spider mite infestations, regularly mist your paper plants to increase humidity levels. This will help prevent the pests from thriving. You can also use insecticidal soap or neem oil to control the population. If the infestation is severe, consider using a miticide specifically formulated for spider mites.

Mealybugs

Mealybugs are small, soft-bodied insects covered in a white, waxy substance. They typically feed on the sap of plants, causing stunted growth and yellowing leaves. Mealybugs are known for their ability to spread quickly and infest neighboring plants.

Identification: Mealybugs are easily identifiable due to their cottony white appearance. They often congregate in protected areas such as leaf joints, stems, and undersides of leaves.

Treatment: For mild infestations, you can manually remove mealybugs using a cotton swab soaked in alcohol or by spraying the infected plant with water. Alternatively, you can use insecticidal soap or horticultural oil to control the population. Regularly inspect your paper plants for signs of mealybug reinfestation and isolate infected plants to prevent spreading.

Scale Insects

Scale insects are small, immobile pests that attach themselves to the stems and leaves of plants, feeding on their sap. They are protected by a hard shell-like covering that makes them difficult to eliminate.

Identification: Scale insects can vary in size and appearance depending on the species. They can be round or oval-shaped and come in colors ranging from brown to black. The presence of sticky honeydew and sooty mold on the plant’s surface is often an indication of scale infestation.

Treatment: For minor scale infestations, you can manually remove the pests using a cotton swab dipped in alcohol or by scraping them off with a toothbrush. Insecticidal soap or horticultural oil can also be used to control the population. However, severe infestations may require the use of systemic insecticides or professional intervention.

Fungus Gnats

Fungus gnats are small, dark-colored flies that lay their eggs in the soil of potted plants. The larvae feed on decaying organic matter and plant roots, resulting in stunted growth and yellowing leaves.

Identification: Adult fungus gnats are approximately 1/8 inch long with long legs and wings. The larvae are translucent and worm-like, often found in the soil feeding on organic matter.

Treatment: To control fungus gnats, allow the soil to dry between watering to discourage their breeding. You can also use sticky traps or yellow sticky cards to catch adult gnats. Applying a layer of sand or gravel on top of the soil can help deter egg-laying. If the infestation persists, consider using biological controls such as Bacillus thuringiensis var. israelensis (Bti) or beneficial nematodes.

Preventing pest infestations in paper plants is crucial for their health and longevity. Regularly inspect your plants for signs of pests, maintain proper cultural practices such as watering and fertilizing appropriately, and ensure good air circulation around your plants. By following these guidelines and promptly treating any infestations, you can keep your paper plants thriving and pest-free.
