Garden Club White Fly White flies are common house plant pests, but can be found outdoors, as well. Fortunately, they cannot survive Minnesota winters. White flies are found mainly on the undersides of leaves. The adults will flutter about when the plant has been disturbed. The young are usually found on the lower leaf surfaces.
Leaves turn yellow and drop off.
Leaf surfaces often become sticky. The various life stages of the white fly exhibit varying degrees of susceptibility to different control measures, which means these measures will have to be used more than once. Be sure that the undersides of the leaves are treated for effective control. Please read and follow all label directions and precautions. Use insecticides only on plants listed on the label.
