If a plant is infested with whiteflies , you will see a cloud of fleeing insects when the works is commove . Whiteflies can dampen a works , eventually leading to plant demise if they are not checked . They can transfer many harmful flora viruses . They also produce a sweet nitty-gritty call honeydew ( covet by ant ) which can chair to an untempting black aerofoil fungal development called sooty moulding .
Possible control : keep weeds down ; use screening in windows to keep them out ; take overrun plant life aside from non - infested plants ; apply a contemplative mulch ( atomic number 13 foil ) under plants ( this repels whiteflies ) ; gob with yellow sticky cards , apply labeled pesticide ; advance raw enemies such as parasitic WASP in the garden ; and sometimes a in effect steady shower of water will wash them off the plant . Pest : Scale InsectsScales are insects , touch to mealy bugs , that can be a trouble on a full variety of plants - indoor and outdoor . Young scales creep until they witness a expert eating site .
