Mealybugs on Indoor Plants: Identification and Treatment Plan
Isolate the plant, remove visible insects and repeat a targeted treatment until new growth stays clean.
Quick answer: Mealybugs look like white cottony clusters around nodes, leaf bases and roots. Isolate the plant, remove visible insects, clean the area and repeat a label-approved treatment because eggs and hidden insects survive one pass.
Inspect hiding places
- Check petiole joints and unfurling leaves.
- Look under pot rims and supports.
- Investigate root mealies when decline continues without visible colonies.
Treat methodically
- Use cotton swabs for small visible clusters.
- Apply horticultural soap, oil or another labelled product correctly.
- Protect the plant from harsh sun after treatment.
Prevent spread
- Quarantine new plants.
- Clean tools between plants.
- Inspect nearby collections weekly for several cycles.
Common mistakes to avoid
- Scraping one cluster and declaring victory
- Using concentrated alcohol across the whole plant
- Fertilising a badly infested plant
What to do next
- Measure your light or inspect the affected plant.
- Check roots, drainage and moisture before buying a treatment.
- Choose one correction and document the result.
