If you have a weigela plant in your garden, you may have encountered crusader bugs. These bugs are small and green, and they can be a nuisance to your plants. They feed on the sap of the plant, which can cause damage to the leaves and flowers. In this article, we will discuss how to get rid of crusader bugs on your weigela plant.
Crusader bugs, also known as Murgantia histrionica, are small insects that belong to the stink bug family. They are about ½ inch long and have a distinctive shield shape. They are bright green in color with red and black markings on their wings. These bugs are often found in gardens and agricultural fields.
The first sign of a crusader bug infestation is the appearance of small holes in the leaves of your weigela plant. As these bugs feed on the sap of the plant, they can cause damage to the leaves and flowers. You may also notice a sticky substance on the leaves, which is called honeydew. This substance is a byproduct of the crusader bug’s feeding and can attract other pests like ants.
There are several ways to get rid of crusader bugs on your weigela plant. Here are some methods that you can try:
One of the easiest ways to get rid of crusader bugs is by handpicking them off your plants. Wear gloves or use a cloth to protect your hands from their odor. You can also use a vacuum cleaner to suck up the bugs.
Neem oil is an organic insecticide that can be used to get rid of crusader bugs. Mix one tablespoon of neem oil with one gallon of water and spray the solution on your plants. This will kill the bugs and prevent them from coming back.
Insecticidal soap is another organic insecticide that can be used to get rid of crusader bugs. Mix two tablespoons of insecticidal soap with one gallon of water and spray the solution on your plants. This will kill the bugs without harming beneficial insects.
Diatomaceous earth is a natural powder that can be used to get rid of crusader bugs. Sprinkle the powder on your plants and around the base of the plant. The diatomaceous earth will dehydrate the bugs and kill them.
If all else fails, you can use chemical insecticides to get rid of crusader bugs. Look for an insecticide that is labeled for stink bugs and follow the instructions on the label carefully. Be sure to wear protective clothing and avoid spraying during windy conditions.
