White Spots on Sago Palm: Likely Mealybugs or Woolly Aphids

Not a Fungus—It’s Insects

The little white spots on your bonsai sago palm fronds and base are almost certainly mealybugs or woolly aphids, not a fungal disease.

Confirm and Treat

• Compare with Google Images for “mealybug” and “woolly aphid.”
• If matched, apply a labeled insecticide (horticultural oil, insecticidal soap, or systemic) per directions.

Early treatment prevents spread to other plants.
