Peace Lily Bugs: The Uninvited Guests

Peace lilies, like any other houseplant, are susceptible to a range of pests and diseases. Let’s shine a spotlight on some of the most common culprits that may invade your peace lily haven.

Mealybugs are tiny, soft-bodied insects that often appear as white, cottony masses on plant leaves and stems. They feed by sucking plant sap, causing yellowing, wilting, and stunted growth.


Aphids are small, pear-shaped insects that come in various colors, including green, black, and yellow. They cluster on new growth and flower buds, feeding on plant sap and secreting a sticky substance called honeydew.


Scale insects attach themselves to plant surfaces and often resemble small, brown or tan bumps. They feed by piercing plant tissue and sucking out fluids, causing leaf yellowing and deformation.

Spider Mites

Spider mites are arachnids rather than insects. They are tiny, often difficult to see with the naked eye, and spin fine webs on leaves. They feed by piercing plant cells and draining their contents, leading to stippling and discoloration.

Thrips are slender, tiny insects with fringed wings. They feed by scraping plant tissue and sucking up the exuded cell contents, causing leaves to appear speckled and distorted.

Fungus Gnats

Fungus gnats are small, dark-colored flies that infest the soil of potted plants. Their larvae feed on plant roots, leading to weakened growth and susceptibility to diseases.

Root Rot

Root rot is a disease caused by fungi that thrive in overly wet soil conditions. It leads to the decay of plant roots, resulting in wilting, yellowing leaves, and eventual plant death.

Mosaic Virus

Mosaic virus can cause distinctive patterns of light and dark green on leaves. It is spread by insects, such as aphids, and can weaken the plant over time.

How to Get Rid of Peace Lily Bugs Naturally

When dealing with peace lily bugs, many plant enthusiasts prefer to use natural and chemical-free methods to protect their green companions. Here are some effective natural remedies to combat common peace lily pests:

1. Neem Oil

Neem oil is derived from the neem tree and is a potent natural insecticide and fungicide. It disrupts the feeding and reproductive cycles of many pests, including aphids, mealybugs, and spider mites.

2. Insecticidal Soap Spray

Insecticidal soap is a gentle yet effective solution for controlling soft-bodied pests like aphids, mealybugs, and thrips. It disrupts their cell membranes and ultimately leads to their demise.

3. Oil Spray

A mixture of vegetable oil and liquid soap can smother pests like scale insects and mealybugs. It should be applied as a spray to thoroughly cover affected plant parts.

4. Herbal Water Spray

Homemade herbal sprays using ingredients like garlic, onion, or chili can deter pests. Blend these ingredients with water and apply the mixture to your plant’s leaves.

5. Pyrethrin

Pyrethrin is a natural insecticide derived from chrysanthemum flowers. It is effective against a wide range of pests but should be used with caution and according to package instructions.

6. Garlic Spray

A garlic spray can repel insects like aphids, mealybugs, and spider mites. Crush garlic cloves and mix with water, then strain and spray on your plant.

7. Diatomaceous Earth

Diatomaceous earth is a fine powder made from the fossilized remains of diatoms. It can be sprinkled on the soil surface to deter crawling insects and pests.

8. Pesticides and Insecticides

If natural remedies prove ineffective, you can resort to pesticides and insecticides. These should be used as a last resort and with care, as they may harm beneficial insects and other wildlife.

9. Horticultural Oil & Canola Oil

Horticultural oil and canola oil can be used to smother pests like scale insects and mealybugs. Dilute the oil in water and apply as a spray.

10. Rubbing Alcohol

Dabbing a cotton swab or cloth soaked in rubbing alcohol on individual pests can help eliminate them.

11. Water Spray

A strong stream of water from a hose can dislodge and remove some pests like aphids and spider mites from your plant.

12. Sticky Traps

Yellow sticky traps can capture flying pests like fungus gnats and aphids. Place them near your plant to reduce infestations. If you want to keep your cat away from your peace lileis then check out my recent article How To Keep Cats Away From Peace Lily ( 18 Methods ).

How to Use Pesticides & Insecticides for Peace Lily Plants

When using pesticides or insecticides on your peace lily, follow these guidelines to ensure safety and effectiveness:

  1. Identify the Pest: Accurately identify the pest afflicting your peace lily to select the right product.
  2. Read the Label: Carefully read and follow the instructions on the pesticide or insecticide label. Pay attention to safety precautions.
  3. Choose the Right Product: Select a product formulated for indoor plants and the specific pests you’re dealing with.
  4. Test on a Small Area: Before treating the entire plant, test the product on a small, inconspicuous area to ensure it doesn’t cause any adverse reactions.
  5. Apply Sparingly: Use the recommended amount of the product and avoid overusing, as it can harm your plant.
  6. Isolate Your Plant: If possible, move your peace lily away from other plants when applying pesticides to prevent the spread of chemicals.
  7. Protect Yourself: Wear appropriate protective gear, such as gloves and a mask, when applying pesticides. Wash your hands thoroughly after handling them.

Why Does My Peace Lily Have Bugs?

Peace lilies can attract bugs for various reasons:

  • Overwatering: Excess moisture in the soil can create favorable conditions for pests like fungus gnats and root rot.
  • Poor Drainage: Inadequate drainage can lead to waterlogged soil, which is a breeding ground for pests.
  • Low Humidity: Peace lilies prefer higher humidity levels, and low humidity can make them more susceptible to spider mites.
  • Environmental Stress: Stressors like improper lighting or extreme temperatures can weaken your plant, making it more susceptible to pests.
  • Contaminated Soil: Using contaminated soil or pots that haven’t been properly cleaned can introduce pests to your plant.

How to Prevent Bugs on Peace Lily

Prevention is often the best approach when it comes to dealing with peace lily bugs. Here are some steps you can take to keep your plant healthy and pest-free:

  • Maintain Proper Drainage: Ensure your peace lily is potted in well-draining soil and has a pot with drainage holes to prevent waterlogged conditions.
  • Monitor Humidity: Use a humidity tray or room humidifier to maintain optimal humidity levels for your peace lily.
  • Regular Inspections: Periodically inspect your plant for signs of pests and address any infestations promptly.
  • Isolate New Additions: Quarantine new plants for a few weeks to ensure they don’t bring pests into your home.
  • Avoid Overwatering: Water your peace lily only when the top inch of soil feels dry to the touch.
  • Proper Lighting: Place your plant in bright, indirect light, as this can help it resist pests and maintain overall health.
  • Repotting: Repot your peace lily every couple of years to refresh the soil and prevent root-bound conditions.
  • Cleanliness: Keep your plant and its surroundings clean. Remove fallen leaves and debris from the soil surface.
