If you haven’t gotten control after multiple treatments, a number of houseplant insecticides are registered for use on scale insects. Handpicking or using a Q-tip dipped in alcohol may also be effective. Use a cloth or a brush to remove both the scale insects and the honeydew from the leaves. If your plant is only lightly affected, you can try washing the leaves and stems with a diluted dish detergent and water solution. It is often best to discard heavily infested plants rather than try to treat them. Multiple treatments may be necessary to fully eliminate an infestation. The crawler stage is most vulnerable to treatment, although it is often difficult to predict when they will be active. As the crawlers molt into adults they stop moving and develop shell-like, waxy, outer coverings that conceal and protect their bodies. Instead of laying eggs, female scale insects give birth to live young called “crawlers”, which are the only mobile life stage. Heavy scale infestations can reduce plant vigor and stunt growth. Unsightly black fungus called sooty mold often grows on the honeydew, making the leaves look dirty and reducing photosynthesis. Brown soft scales feed on plant sap with piercing-sucking mouthparts and excrete a sweet, sticky fluid called honeydew. Brown soft scales appear as small, flat, oval, yellowish brown bumps on the stems and leaves of houseplants. They are immobile for most of their life cycle and often avoid detection when their numbers are low. Scale insects can be incredibly frustrating and difficult to manage.
