How to Get Rid of Crusader Bugs on Red Hill Plant

Crusader bugs, also known as Mictis profana, are small insects that belong to the family Coreidae. These bugs are commonly found in the United States, particularly in the southern regions. They can be a nuisance for gardeners and homeowners, as they feed on various plants, including the Red Hill plant (Eremophila maculata). However, there are several effective methods to get rid of crusader bugs and protect your Red Hill plant from damage.

Identify the Crusader Bugs

Before you start implementing any pest control strategies, it is crucial to identify the crusader bugs correctly. These bugs are around 1 inch long and have an elongated body shape. They are typically brown or gray, with distinctive markings on their wings. Crusader bugs have a shield-like appearance with a narrow head and long antennae.

Natural Predators

One of the most effective ways to control crusader bug populations is by promoting the presence of their natural predators in your garden. Several insects and animals feed on crusader bugs, including birds, spiders, ladybugs, and assassin bugs. By attracting these natural predators to your garden, you can create a more balanced ecosystem that keeps the crusader bug population under control.

To attract birds to your garden, provide them with bird feeders and bird baths. Planting flowers that produce nectar will also help attract beneficial insects like ladybugs. Additionally, creating habitats such as rock piles or log piles can provide shelter for spiders and assassin bugs.

Handpicking

If the crusader bug population is manageable, handpicking them off your Red Hill plant can be an effective control method. Carefully inspect each leaf and stem for the presence of crusader bugs and remove them by hand. Use gloves to protect your hands as some insects may release a foul-smelling substance when disturbed. Drop the captured bugs into a container filled with soapy water to ensure they are killed.

Handpicking is a labor-intensive method, especially if the infestation is severe. However, it can be a useful technique to reduce the pest population and prevent further damage to your Red Hill plant.

Neem Oil

Neem oil is a natural insecticide derived from the seeds of the neem tree (Azadirachta indica). It has been used for centuries to control a wide range of pests, including crusader bugs. Neem oil disrupts the feeding and reproductive behavior of insects, eventually leading to their death.

To use neem oil as a crusader bug control method, dilute it according to the manufacturer’s instructions and spray it on your Red Hill plant. Ensure that you cover both sides of the leaves and stems thoroughly. Repeat the application every 7-10 days or as directed on the product label until the bug population is under control.

Insecticidal Soap

Insecticidal soap is another effective option for controlling crusader bugs on your Red Hill plant. These soaps contain fatty acids that break down the outer protective layer of insects, causing dehydration and death. Insecticidal soap is readily available in garden centers or can be made at home using mild dish soap and water.

To use insecticidal soap, mix it according to the manufacturer’s instructions or create your own solution by mixing 1-2 tablespoons of mild dish soap with a gallon of water. Spray this solution onto your Red Hill plant, ensuring that all parts are thoroughly coated. Repeat the application every 5-7 days until the crusader bug population is reduced.

Cultural Control Methods

Implementing cultural control methods can help prevent crusader bug infestations and protect your Red Hill plant in the long term. Here are some practices you can adopt:

1. Crop rotation: Avoid planting Red Hill plants in the same location year after year. Crop rotation helps disrupt the life cycle of pests and reduces the chances of reinfestation.
2. Weed control: Keep your garden free from weeds, as they can provide hiding places and alternative food sources for crusader bugs.
3. Sanitation: Regularly remove plant debris and fallen leaves from the vicinity of your Red Hill plant. These organic materials can harbor pests and increase the risk of infestation.

Chemical Control

If all other methods fail to control the crusader bug population, chemical control options are available as a last resort. Consult with a professional pest control service or your local agricultural extension office for appropriate insecticides that are safe to use on Red Hill plants. Always follow the instructions provided on the product label and take necessary precautions to protect yourself, other beneficial insects, and the environment.

Conclusion

Getting rid of crusader bugs on your Red Hill plant requires a combination of strategies, including natural predators, handpicking, neem oil, insecticidal soap, cultural control methods, and, if necessary, chemical control. By implementing these methods effectively, you can protect your Red Hill plant from damage and enjoy a thriving garden free from these pesky insects.
