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 Mealybugs 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 substances. This sometimes attracts wasps and ants, and also provides a medium for sooty mould to grow on. While feeding they weaken the plants and can spread diseases.

Can be difficult to kill as they often infest hard to reach places.


Natural predators such as lacewings and ladybirds will help control numbers and help stop them becoming an issue.

Control ants, as some species harvest the honeydew and offer them some protection.
