How to Get Rid of Crusader Bugs on Dianella Plant

Dianella plants, commonly known as Flax Lily, are a popular choice among gardeners because of their attractive foliage and vibrant flowers. However, these plants can be vulnerable to pests, one of which is the crusader bug. These insects can cause significant damage to the plant if left untreated. In this article, we’ll discuss how to identify crusader bugs and get rid of them.

Identifying Crusader Bugs

Crusader bugs are small insects that are about 10mm in length. They have a distinctive shape, with a long narrow head and a broad body. They are usually black, but some species may have red or yellow markings. Crusader bugs feed on the sap of plants, including Dianella plants, by piercing the stems and leaves with their mouthparts.

If you notice your Dianella plant has yellowing leaves or wilting stems, it could be a sign of crusader bug infestation. You may also notice small black or brown insects crawling on the plant.
