White Cottony Balls on Banana Plant: Mealybugs or Cottony Aphids

Cotton-like white balls on indoor banana plant leaves are almost certainly mealybugs or cottony aphids—sap-sucking insects that hide under white wax.

Confirm It’s Insects

Pierce a cotton ball with a toothpick. If liquid oozes out, it’s an insect. If dry and powdery, could be mineral deposit (unlikely).

Control Depends on Use

• Ornamental only: Use insecticidal soap, neem oil, or systemic imidacloprid soil drench.
• Edible fruit: Avoid systemics. Use insecticidal soap, neem oil, or manual removal with alcohol swabs.

Environmental Factor

Hot/cold drafts from HVAC stress the plant, making it more susceptible. Stabilize temperature if possible.
