Whiteflies Whiteflies There are many species of these tiny, snow-white winged insects that attack a wide range of plants including house plants, garden flowers, vegetables, weeds and poinsettias. Adults and nymphs suck plant sap. Nymphs (which are the immature stages) may be found on the underside of leaves. Heavy feeding causes yellowing, premature leaf drop, and stunting of plants. These insects excrete sticky honeydew onto upper and lower leaf surfaces, permitting the development of black sooty mold fungus.

Control Control • When purchasing plants inspect carefully to be sure plants are not infested. • Eliminate weeds in and around gardens that harbor whiteflies. • Begin insecticidal soap or chemical applications as soon as infestations are noticed (read the label FIRST). • When purchasing plants inspect carefully to be sure plants are not infested. • Eliminate weeds in and around gardens that harbor whiteflies. • Begin insecticidal soap or chemical applications as soon as infestations are noticed (read the label FIRST).
