Zamioculcas pests & diseases
Common pests (such as spider mites, thrips, mealybugs)
Zamioculcas is generally resistant to most pests, but infestations can still occur, especially in dry indoor conditions. The most common pests on ZZ plants are:
- Spider mites (tiny, web-spinning insects that cause speckled or faded leaves)
- Thrips (small, slender insects that leave silvery streaks or spots on leaves)
- Mealybugs (white, cottony clusters on stems and leaf bases)
- Occasionally, scale insects or fungus gnats may appear
Recognizing symptoms
- Fine webbing on or between leaves (spider mites)
- Silvery, pale, or stippled patches (thrips or spider mites)
- Sticky residue or white, cottony spots (mealybugs)
- Brown, hard bumps on stems (scale insects)
- Sudden yellowing or dropping leaves (can be pest-related, but also check for watering issues)
Preventing pests
- Check your plant regularly, especially the undersides of leaves and leaf bases
- Keep humidity moderate (spider mites thrive in dry air)
- Isolate new plants for a few weeks before placing them near your ZZ plant
- Wipe leaves gently with a damp cloth to remove dust and spot early signs of pests
What to do if your plant is affected
- Remove visible pests by hand or with a gentle stream of water
- Wipe affected areas with a damp cloth
- For persistent infestations, consider removing the most affected leaves
- If the problem continues, consult a plant specialist for further advice
When to seek professional help
If pests return repeatedly or the plant's health declines despite intervention, consider contacting a plant care expert. Severe infestations may require replacing the plant.
