Whiteflies on Houseplants: Lifecycle & Management

Know the Enemy

Tiny, white, moth-like insects (1–2 mm) that flutter when disturbed. Adults lay eggs on leaf tops, but the real damage is done by immobile nymphs feeding on undersides, causing yellowing, weakening, and honeydew (leading to sooty mold).

Two-Pronged Attack

1. Yellow sticky cards trap flying adults, breaking the reproductive cycle.
2. Green Solution or insecticidal soap sprayed on leaf undersides every 5–7 days kills nymphs. Neem oil also effective.

Cultural Controls

• Vacuum adults gently (empty bag outside).
• Remove heavily infested leaves.
• Improve air circulation.
• Quarantine new plants for 2 weeks.

Whiteflies reproduce fast—act at first sight. Consistency wins.
