What are Crusader Bugs?

Crusader bugs, also known as marmorated stink bugs, are a type of insect that feeds on the sap of plants. They are brown in color and have a shield-shaped body. These bugs can be found in gardens and fields and are commonly seen in the late summer and early fall.

Signs of Crusader Bug Infestation

The first sign of a crusader bug infestation on cup plants is the appearance of small, yellow spots on the leaves. These spots will eventually turn brown and wilt. You may also notice that the plant is not growing as well as it should be, or that it has become stunted.

How to Get Rid of Crusader Bugs on Cup Plants

There are several effective ways to get rid of crusader bugs on cup plants. Here are some methods you can try:

1. Handpicking

One of the most effective ways to get rid of crusader bugs is to handpick them off the plant. This method is best done early in the morning when the bugs are still sluggish from the cool night air. Wear gloves and gently pick the bugs off the plant and drop them into a bucket of soapy water.

2. Neem Oil

Neem oil is a natural insecticide that can be used to kill crusader bugs on cup plants. Mix neem oil with water according to the instructions on the bottle and spray it onto the plant, focusing on the areas where the bugs are most prevalent.

3. Insecticidal Soap

Insecticidal soap is another option for getting rid of crusader bugs on cup plants. Mix the soap with water according to the instructions on the bottle and spray it onto the plant. Be sure to cover all areas of the plant, including the undersides of the leaves.
