How to Get Rid of Crusader Bugs on Chrysanthemum Plant

Chrysanthemums are a beautiful addition to any garden, but they are also vulnerable to different types of bugs. One of the most common pests that chrysanthemum plants face is the crusader bug. These small insects can quickly infest your chrysanthemum plant and cause severe damage if not dealt with promptly.

In this article, we will discuss some effective ways to get rid of crusader bugs on your chrysanthemum plant and keep your garden thriving.

What Are Crusader Bugs?

Crusader bugs, also known as marmorated stink bugs, are brownish-gray insects with white bands on their antennae and black and white markings on their legs. They usually grow up to ¾ inch long and have a shield-like body shape. They are called stink bugs because they release an unpleasant odor when threatened or crushed.

Crusader bugs feed on plant sap by piercing the plant’s tissue with their mouthparts. They usually target fruits and vegetables, but they also infest flowers such as chrysanthemums.

Signs of Crusader Bug Infestation

The first signs of crusader bug infestation are small holes or punctures in the leaves of your chrysanthemum plant. As the infestation grows, you may also notice discoloration or wilting of the leaves. In severe cases, the bugs may cause the flowers to drop off prematurely.

How to Get Rid of Crusader Bugs

1. Handpicking

One of the simplest ways to get rid of crusader bugs is by handpicking them off your chrysanthemum plant. Wear gloves and carefully check the undersides of leaves and stems where they like to hide. Drop them into a container filled with soapy water to kill them.

2. Vacuuming

You can also use a handheld vacuum cleaner to suck up crusader bugs from your chrysanthemum plant. This method is more effective for larger infestations, but make sure to empty the vacuum bag immediately after use to prevent the bugs from escaping.

3. Neem Oil Spray

Neem oil is a natural insecticide that can help control crusader bugs on your chrysanthemum plant. Mix one tablespoon of neem oil and one teaspoon of dish soap in a gallon of water and spray it on the affected areas. The neem oil works by disrupting the insects’ hormonal balance, making it difficult for them to feed and reproduce.

4. Insecticidal Soap

Insecticidal soap is another effective solution for controlling crusader bugs on your chrysanthemum plant. Mix two tablespoons of insecticidal soap in a gallon of water and spray it on the infested areas. The soap works by suffocating the bugs, so make sure to cover all parts of the plant thoroughly.

How to Prevent Crusader Bugs Infestation

Prevention is always better than cure when it comes to pest control. Here are some preventive measures you can take to reduce the risk of crusader bug infestation in your garden:

• Clean up fallen leaves and debris around your chrysanthemum plant regularly.
• Use row covers to protect your plants from pests.
• Keep your garden free from weeds, which can attract pests and provide them with shelter.
• Rotate your crops to reduce pest pressure.
• Use companion planting to deter pests naturally.
