Whiteflies usually occur in groups on the undersides of leaves. They derive their name from the mealy, white wax covering the adult’s wings and body. Adults are tiny insects with yellowish bodies and whitish wings.
Whiteflies are tiny, sap-sucking insects that are frequently abundant in vegetable and ornamental plantings. They excrete sticky honeydew and cause yellowing or death of leaves. Whiteflies develop rapidly in warm weather, and populations can build up quickly in situations where natural enemies are destroyed and weather is favorable. Most whiteflies have a wide host range that includes many weeds and crops. In many parts of California, they breed all year, moving from one host to another as plants are harvested or dry up. Like aphids, whiteflies excrete honeydew, so leaves may be sticky or covered with black sooty mold. The honeydew attracts ants, which interfere with the activities of natural enemies that may control whiteflies and other pests. Management is difficult.
Whiteflies can be controlled through a variety of means including biological and chemical means as well as removal. Clark Pest Control offers a variety of solutions for your lawn and garden and can address problems you are having with both whiteflies and ants in your yard.
