Mealy Bug

08 May, 2021

Common name for many of the small insects in the family Pseudococcidae. The females are small sap sucking unarmoured scale insects. However unlike most scale insects they often retain legs and the ability to crawl around. The males are smaller, gnat like and can fly around.

The female Mealy bugs are covered by pale or white thread or powder-like coatings, and can often be found feeding from stems or leaves. They will also attack the roots and bulbs of some plants.


When feeding they excrete honeydew, a sweet sticky substance. This sometimes attracts wasps and ants, and also provides a medium for sooty mold to grow on. While feeding they weaken the plant and can spread diseases.


They can be difficult to kill as they often infest the soil and hard to reach places.
