Whiteflies are tiny, winged insects that feed by sucking sap from plants. They are found on the undersides of leaves and are active during the day. Larvae are the size of a pinhead and are wingless. Because they feed more heavily than the adults, they cause more damage. Whiteflies can be controlled on our Shrub & Tree Program with a contact insecticide for larvae or systemic insecticide for adults. Often, the first thing you will notice with whiteflies (or other sucking insects) infestation is the presence of sooty mold. (For additional information see “Sooty Mold Below”)
