Updated: April 20, 2022

If you have a dumb plant and have noticed small, black bugs crawling on the leaves or stems, chances are you have encountered crusader bugs. These pests can do significant damage to your plant if left unchecked. In this article, we will discuss how to identify crusader bugs, the damage they can cause, and most importantly, how to get rid of them.

What are Crusader Bugs?

Crusader bugs are a type of true bug that belongs to the family Coreidae. They are commonly found in gardens and agricultural fields across the United States. These bugs are typically black or dark brown and have a distinctive shield shape. They can grow up to 1 inch in length and have long antennae.

Damage Caused by Crusader Bugs

Crusader bugs feed on the sap of plants, which can cause significant damage if left unchecked. They can cause leaves to wilt and turn yellow or brown. In severe cases, they can cause the plant to die. Additionally, crusader bugs can spread diseases from one plant to another.

How to Get Rid of Crusader Bugs

There are several ways to get rid of crusader bugs on dumb plants:

1. Manual Removal

One of the easiest ways to get rid of crusader bugs is to manually remove them from your plant. Use a pair of tweezers or your fingers to pick them off and drop them into a bucket of soapy water. This method is best for small infestations.

2. Insecticidal Soap

Insecticidal soap is a safe, effective way to control crusader bugs. It works by suffocating the bugs and disrupting their cell membranes. Apply the soap directly to the bugs and any affected areas of the plant. Be sure to follow the manufacturer’s instructions for application rates and frequency.

3. Neem Oil

Neem oil is another effective natural remedy for crusader bugs. It works by disrupting the insects’ feeding and reproductive processes. Mix the neem oil with water according to the manufacturer’s instructions and spray it on your plant, focusing on the affected areas.

4. Diatomaceous Earth

Diatomaceous earth is a natural substance that is made from the fossilized remains of diatoms, a type of algae. It works by dehydrating insects and causing them to die. Sprinkle the diatomaceous earth on your plant, focusing on the affected areas.

5. Companion Planting

Companion planting involves planting certain plants alongside each other to repel pests. Marigolds, for example, are known to repel crusader bugs. Plant marigolds around your dumb plant to deter crusader bugs from attacking it.


Are crusader bugs harmful to humans?

No, crusader bugs are not harmful to humans.

How can I prevent crusader bugs from infesting my dumb plant?

Keep your plant healthy by watering and fertilizing it regularly. Avoid over-fertilizing, as this can attract pests. Inspect your plant regularly for signs of infestation and take action immediately if you notice any bugs.

Can I use chemical pesticides to control crusader bugs?

While chemical pesticides can be effective, they can also harm beneficial insects and other wildlife in your garden. It’s best to try natural remedies first before resorting to chemicals.

In conclusion, crusader bugs can be a nuisance for dumb plant owners, but with the right approach, they can be controlled effectively. Use a combination of manual removal, insecticidal soap, neem oil, diatomaceous earth, and companion planting to get rid of these pests and keep your plant healthy.
