Biology
Whiteflies are common pests in the greenhouse and garden. The adult whitefly is a tiny (1/10″ or less), white, moth-like insect. They typically feed on the underside of leaves, flying up in clouds when disturbed. The immature whiteflies (nymphs) are also found on the underside of leaves, and are oval, flat, and variously-colored. Whiteflies feed by sucking sap from plant tissues. Damaged leaves wilt, turn yellow or brown, and may drop. Plants may be stunted by severe infestations. Whiteflies also produce honeydew, a sweet, sticky material which may attract ants or become covered with growth of dark sooty mold.
Management Options
Use Integrated Pest Management (IPM) for successful plant problem management.
Non-chemical Management
Select non-chemical management options as your first choice!
- Inspect new plants thoroughly before planting. New plants often introduce whiteflies.
- Natural enemies such as ladybird beetles, spiders, and parasitic wasps help control whitefly populations. Avoid use of broad-spectrum insecticides which kill beneficials.
Chemical Management
IMPORTANT: Visit Home and Garden Fact Sheets for more information on using pesticides.
- Apply according to label instructions when whitefly is first seen.
