Most Common Snake Plant Pests:
Identification and Treatment Guide

Updated: July 16, 2023

Snake plants, also known as Sansevieria, are popular houseplants due to their low maintenance requirements and unique foliage. However, like any other plant, snake plants are susceptible to pests. These pests can cause damage to the leaves, weaken the plant, and even spread to other plants in your collection if left untreated. In this article, we will discuss the most common snake plant pests, how to identify them, and the best treatment strategies to keep your snake plant healthy and pest-free.

Spider Mites

Spider mites are tiny arachnids that can infest snake plants and other houseplants. They are most commonly found in warm and dry environments. You may notice a fine webbing on the leaves of your snake plant, as well as tiny specks that move when disturbed. Spider mites feed on the sap of the plant, leading to yellowing or browning of the leaves.

To treat spider mite infestations, start by isolating the affected plant from others to prevent further spread. Use a strong stream of water to wash off the mites from the leaves. Follow up with an organic insecticidal soap or neem oil spray to kill any remaining mites. Repeat this treatment every few days until the infestation is under control.

Mealybugs

Mealybugs are small, soft-bodied insects that often appear as tiny white cotton-like masses on the leaves and stems of snake plants. They feed on the sap of the plant and can cause stunted growth, yellowing leaves, and a sticky residue called honeydew.

To get rid of mealybugs, start by physically removing them using a cotton swab dipped in rubbing alcohol or soapy water. Ensure you reach all the nooks and crannies where these pests hide. For larger infestations, you can use a systemic insecticide specifically formulated for mealybugs. Applying a neem oil spray can also be effective in controlling these pests.

Scale Insects

Scale insects are small, oval-shaped pests that attach themselves to the leaves and stems of snake plants. They have a protective shell-like covering that makes them difficult to remove. Scale insects feed on the plant’s sap, causing yellowing, stunted growth, and even leaf drop.

To tackle scale infestations, start by manually removing the scales using a cotton swab dipped in rubbing alcohol or soapy water. Be sure to reach all the crevices where these pests hide. For larger infestations, you can use an insecticidal soap or horticultural oil spray. Apply the spray according to the manufacturer’s instructions, ensuring thorough coverage of all affected areas.

Fungus Gnats

Fungus gnats are small flying insects that are attracted to moist soil conditions. They lay their eggs in the soil, and the larvae feed on organic matter and the roots of the plant. Signs of a fungus gnat infestation include small flies hovering around the plant and tiny black larvae in the soil.

To control fungus gnats, start by allowing the top inch of soil to dry out between waterings. This will discourage the gnats from laying their eggs in the moist soil. You can also use yellow sticky traps to catch adult gnats and disrupt their breeding cycle. If the infestation persists, you may need to repot your snake plant using fresh, well-draining soil to eliminate any remaining larvae.

Aphids

Aphids are small insects that can vary in color from green to black. They cluster on the undersides of leaves and suck on the plant’s sap, causing distorted growth and yellowing leaves. Aphids can reproduce rapidly, leading to large infestations if left untreated.

To get rid of aphids, start by washing them off the leaves with a strong stream of water. This will physically remove a significant portion of the pests. You can also use insecticidal soap or neem oil spray to kill any remaining aphids. Repeat the treatment every few days until the infestation is eradicated.

Prevention is Key

While dealing with snake plant pests can be frustrating, prevention is the best strategy to keep your plants healthy. Here are some tips to prevent pest infestations:

  1. Inspect new plants before bringing them indoors to ensure they are pest-free.
  2. Maintain good hygiene by regularly cleaning and dusting your plants.
  3. Avoid overwatering to prevent conditions that attract pests.
  4. Provide adequate air circulation around your plants.
  5. Quarantine any newly acquired plants for a few weeks to monitor for signs of pests.

By following these preventative measures and promptly addressing any pest issues, you can enjoy healthy and thriving snake plants in your home.

In conclusion, snake plants can be affected by a variety of pests, including spider mites, mealybugs, scale insects, fungus gnats, and aphids. By learning to identify these pests and implementing appropriate treatment strategies, you can effectively control and eliminate infestations. Remember, prevention is key in keeping your snake plants healthy and pest-free.
