How to Get Rid of Crusader Bugs on French Lavender Plant

French lavender is a beautiful and fragrant plant that is commonly grown in gardens and patios. However, like all plants, it is susceptible to pests such as crusader bugs. These bugs can cause significant damage to the plant if not controlled in time. In this article, we will explore how to get rid of crusader bugs on French lavender plants.

What are Crusader Bugs?

Crusader bugs are a type of shield bug that belongs to the family Pentatomidae. They are commonly found in gardens and fields and are known for their distinctive shield-shaped bodies. The adult bugs are usually green or brown in color and have a flattened appearance. They feed on the sap of plants and can cause significant damage to crops and ornamental plants like French lavender.

Signs of Crusader Bug Infestation

The first sign of a crusader bug infestation is the presence of adult bugs on the plant. These bugs are usually found on the leaves or stems of the plant, feeding on the sap. As they feed, they secrete a toxic substance that can cause the leaves to wilt and turn yellow. You may also notice black spots on the leaves, which are a sign of excrement from the bugs.

How to Get Rid of Crusader Bugs

There are several ways to get rid of crusader bugs on French lavender plants. Here are some effective methods:

1. Handpicking

One of the easiest ways to get rid of crusader bugs is to handpick them from the plant. Wear gloves and carefully remove each bug from the plant, placing them in a container filled with soapy water. This method is best used for small infestations.

2. Neem Oil

Neem oil is a natural insecticide that is effective against crusader bugs. Mix one tablespoon of neem oil with one liter of water and spray the mixture on the plant, paying close attention to the undersides of the leaves. Repeat this process every two weeks until the bugs are gone.

3. Insecticidal Soap

Insecticidal soap is a safe and effective way to get rid of crusader bugs on French lavender plants. Mix one tablespoon of insecticidal soap with one liter of water and spray the mixture on the plant, focusing on the areas where you see the bugs. Repeat this process every two weeks until the bugs are gone.

Prevention Tips

Preventing crusader bug infestations is easier than getting rid of them. Here are some tips to prevent crusader bugs from infesting your French lavender plants:
