Sap loss may cause poor, stunted growth. Death of infested plants is possible in severe cases. More commonly noticed than the scales is the large quantity of a sweet sticky liquid called honeydew that is excreted by the scale insects. Honeydew can make a sticky, shiny mess on the plant and nearby furniture and floors. A black fungus called sooty mold may grow on the honeydew.
Scale insects are often difficult to control.
There are several well-known remedies that can be tried in an attempt to eliminate scales from a houseplant. However, there is no easy, simple cure for a scale infestation. This is a laborious task that works only on small, large-leafed plants. Dabbing each scale with an alcohol-soaked cotton swab is another possibility on lightly infested plants. Sprays can be used but success will depend upon thoroughness and persistence.
