Common house plant pests: Whitefly

Detection:

Whiteflies are dandruff-like tiny insects with two pairs of wings that are covered in a white powdery wax. Younger stages are wingless, and damage the plants severely by sucking out their juices. The adults live mostly on the underside of leaves and especially like newly unfurled leaves. Tapping the plant will cause them briefly to take flight. Once an infestation has been discovered it will quickly spread and you should isolate the plant if this is possible. Foliage will eventually yellow and drop as the infestation strengthens. Like most of these pests, whiteflies excrete a sticky honeydew which could attract a black sooty mould.
