Common Calathea Zebra Plant Pests:
Prevention and Control Methods

Updated: March 15, 2023

The Calathea Zebra plant, also known as Calathea zebrina or Zebra plant, is a popular houseplant due to its striking green foliage with bold white stripes. However, like any other plant, it is susceptible to various pests that can damage its leaves and reduce its overall health. Here are some common Calathea Zebra plant pests and tips on how to prevent and control them.

Spider Mites

Spider mites are tiny pests that usually appear in clusters on the underside of the leaves. They feed on the sap of the plant, causing yellow spots on the foliage, webbing, and eventually leaf drop. To prevent spider mites, mist your Calathea Zebra plant regularly to increase humidity levels. Also, avoid over-fertilizing your plant, as this can attract spider mites. If you notice spider mites on your plant, isolate it from other plants and apply insecticidal soap or neem oil to eradicate the pests.

Mealybugs

Mealybugs are soft-bodied insects that appear as white cottony masses on the leaves, stems, and roots of the Calathea Zebra plant. They suck sap from the plant, causing stunted growth, yellowing of leaves, and sooty mold growth. To prevent mealybugs, inspect your plants regularly and quarantine any infested plants immediately. Use a cotton swab dipped in rubbing alcohol to remove visible mealybugs from the plant. If the infestation is severe, use insecticidal soap or neem oil to control the pests.

Scale Insects

Scale insects are small oval-shaped pests that attach themselves to the stems and leaves of the Calathea Zebra plant. They feed on the sap of the plant and secrete a sticky substance called honeydew that attracts ants and promotes fungal growth. Scale insects can cause yellowing of leaves, stunted growth, and leaf drop if left uncontrolled. To prevent scale insects, wipe down your plants with a damp cloth regularly. You can also use neem oil or insecticidal soap to control scale insects.

Fungus Gnats

Fungus gnats are small black flies that usually appear around potted plants. They lay their eggs in moist soil and feed on decaying organic matter. Fungus gnats do not damage the Calathea Zebra plant directly but can be annoying to deal with. To prevent fungus gnats, avoid overwatering your plants and ensure proper drainage. You can also use sticky traps or beneficial nematodes to control fungus gnats.

Thrips

Thrips are tiny insects that feed on the foliage of the Calathea Zebra plant. They cause silver or bronze streaks on the leaves and can lead to distorted growth if left unchecked. To prevent thrips, keep your plants away from other infested plants or materials. You can also use insecticidal soap or neem oil to control thrips.

Whiteflies

Whiteflies are small winged insects that suck sap from the leaves of the Calathea Zebra plant. They secrete honeydew that attracts ants and promotes fungal growth on the foliage. Whiteflies can cause yellowing of leaves, stunted growth, and premature leaf drop if left uncontrolled. To prevent whiteflies, inspect your plants regularly and quarantine any infested plants immediately. Use insecticidal soap or neem oil to control whiteflies.

Conclusion

Preventing pests from attacking your Calathea Zebra plant is easier than treating an infestation. Inspect your plants regularly for signs of pest activity and take action immediately if you notice anything unusual. Remember to quarantine any infested plants to prevent spreading pests to other healthy plants.
