Whitefly on Poinsettias: Isolate and Spray

Tiny white flying bugs on your 4 poinsettias = whitefly. Greenish larvae on leaf undersides suck sap and leave sticky honeydew.

Treatment

1. Isolate immediately—whitefly spread fast.
2. Spray insecticide labeled for whitefly (neem oil, pyrethrin, or systemic).
3. Repeat every 3 days × 3–4 treatments.
4. Check undersides of leaves each time.

Prevention

Inspect new plants. Yellow sticky traps catch adults.
