Peacock plant pests: how to identify and prevent them

Common pests on peacock plant
Peacock plants (Calathea species) can be affected by several indoor plant pests. The most frequent are:
- Spider mites (tiny, red or yellowish, often with fine webbing on leaf undersides)
- Thrips (small, slender insects that move quickly and cause silvery streaks or spots)
- Aphids (soft-bodied, green or black insects, usually on new growth)
- Mealybugs (white, cottony clusters on stems or leaf joints)
Symptoms of pest infestation
- Fine webbing, especially on the underside of leaves (spider mites)
- Silvery or pale spots, streaks, or distorted leaves (thrips)
- Sticky residue (honeydew) or visible insects on new leaves (aphids, mealybugs)
- Leaf edges turning brown or curling, sometimes with visible pests
Preventive measures
- Check new plants for pests before bringing them indoors.
- Maintain moderate humidity (above 50%) to discourage spider mites.
- Wipe leaves gently with a damp cloth every few weeks to remove dust and spot early signs of pests.
- Keep plants spaced to allow airflow and reduce pest spread.
- Isolate affected plants to prevent pests from spreading to others.
When to seek professional help
If pests persist after repeated manual removal or if the infestation spreads rapidly, consider consulting a professional for further advice. Avoid using chemical treatments unless recommended for indoor use and safe for Calathea species.
