How to Get Rid of Crusader Bugs on Creeping Jenny Plant

Creeping Jenny plant, also known as Lysimachia nummularia, is a low-growing perennial that is often used as a ground cover in gardens. It is a hardy plant that can grow in almost any soil type and can tolerate both sun and shade. However, like any other plant, it can be affected by pests and diseases. One of the most common pests that affect the creeping Jenny plant is the crusader bug. In this article, we will discuss how to get rid of crusader bugs on creeping Jenny plant.

What are Crusader Bugs?

Crusader bugs, also known as Mictis profana, are small insects that are commonly found in North America. They are also known as scentless plant bugs because they do not emit any odor when disturbed. These bugs are usually brown or gray in color, and they have a distinctive triangular shape.

Crusader bugs feed on the sap of plants, including the creeping Jenny plant. They use their sharp mouthparts to pierce the plant’s tissue and suck out the sap. This can cause damage to the plant, which can lead to stunted growth, yellowing leaves, and even death.

Signs of Crusader Bug Infestation

The first sign of a crusader bug infestation on creeping Jenny plant is the appearance of small white or yellow spots on the leaves. These spots are caused by the feeding activity of the bugs. As the infestation progresses, the leaves may turn yellow or brown and start to wilt. The bugs themselves may also be visible on the plant, especially if you look closely at the undersides of the leaves.

How to Get Rid of Crusader Bugs on Creeping Jenny Plant

Getting rid of crusader bugs on creeping Jenny plant requires a multi-pronged approach that involves both chemical and non-chemical methods.

1. Handpicking

The first step in controlling crusader bugs on creeping Jenny plant is to handpick them off the plant. This method is best used for small infestations. Look for the bugs on the undersides of the leaves and remove them by hand. You can also shake the plant gently to dislodge the bugs and then collect them on a sheet of paper.

2. Insecticidal Soap

Insecticidal soap is a natural, non-toxic way to control crusader bugs on creeping Jenny plant. It works by suffocating the bugs and disrupting their cell membranes. To use insecticidal soap, mix it according to the instructions on the label and spray it directly onto the plant, focusing on the undersides of the leaves where the bugs are most likely to be found.

3. Neem Oil

It works by disrupting the insects’ hormonal balance, which makes it difficult for them to feed and reproduce. To use neem oil, mix it with water according to the instructions on the label and spray it onto the plant, focusing on the undersides of the leaves.

4. Chemical Insecticides

If non-chemical methods fail to control crusader bugs on creeping Jenny plant, you may need to resort to chemical insecticides.
