Identifying and Controlling Whiteflies on Hibiscus Plants

Recognizing Whiteflies

The tiny white, lice‑like insects on your hibiscus are whiteflies. They cluster on leaf undersides and buds, weakening the plant by sucking sap.

Organic Control Options

• Insecticidal soap: Spray 1 tablespoon mild dish soap (not detergent) per gallon of water every 3–5 days until infestation subsides.
• Yellow sticky traps: Whiteflies are attracted to yellow. Hang commercial traps or make your own with yellow poster board coated in molasses or clear glue.
• Pyrethrum and rotenone: These plant‑derived insecticides are highly effective but also kill beneficial insects. They can be applied up to harvest day.

Prevention

Inspect new plants before bringing them indoors. Use row covers on young plants and maintain good air circulation to discourage whiteflies.
