How to Get Rid of Crusader Bugs on Dew Plant

Updated: February 19, 2023

Dew plants are beautiful and unique plants that thrive in moist environments. However, they are also prone to infestations from a variety of pests, including crusader bugs. These bugs can quickly destroy your dew plant if left unchecked. Fortunately, there are several ways to get rid of crusader bugs on dew plants.

Identifying Crusader Bugs

Crusader bugs, also known as Mictis profana, are small insects that are less than half an inch long. They have a distinctive black and orange color pattern and are usually found in groups on the undersides of leaves. They feed on the sap of the plant and can cause serious damage if left untreated.

Natural Remedies

There are several natural remedies that can be used to get rid of crusader bugs on dew plants. One of the most effective is neem oil, which is a natural insecticide that disrupts the crusader bug’s feeding and reproductive habits. Simply mix a few drops of neem oil with water in a spray bottle and apply it to the affected areas of the plant.

Another effective natural remedy is diatomaceous earth, which is a fine powder made from the fossilized remains of diatoms. Sprinkle a thin layer of diatomaceous earth over the leaves of the plant, making sure to cover both sides of the leaves. The diatomaceous earth will stick to the crusader bugs and cause them to dehydrate and die.

Chemical Insecticides

If natural remedies do not work, chemical insecticides can be used as a last resort. However, it is important to use these products with caution as they can harm beneficial insects as well as crusader bugs.

One effective chemical insecticide for controlling crusader bugs is pyrethrin, which is derived from chrysanthemum flowers. Pyrethrins quickly kill crusader bugs on contact and are safe to use on most plants. However, they can be harmful to bees and other beneficial insects, so it is important to only use them when necessary.


Prevention is always better than cure when it comes to pest control. To prevent crusader bugs from infesting your dew plant in the first place, it is important to keep the plant healthy and well-watered. Avoid over-fertilizing as this can attract pests. Regularly inspect your plant for signs of infestation and take action at the first sign of trouble.


How do I know if my dew plant has a crusader bug infestation?

Look for small black and orange insects on the undersides of the leaves. You may also notice discoloration or wilting of the leaves.

Can I use neem oil on other plants?

Yes, neem oil is safe to use on most plants and is effective against a wide range of pests.

Are chemical insecticides safe for pets?

Chemical insecticides can be harmful to pets if ingested. Always read the label carefully before using any chemical insecticide and keep pets away from treated areas until the product has dried.

Can I eat my dew plant after using insecticides?

It is not recommended to eat plants that have been treated with insecticides. Always follow the manufacturer’s instructions carefully and wait until the recommended waiting period has passed before consuming any produce from treated plants.

In conclusion, crusader bugs can be a serious threat to your dew plant, but with proper identification and treatment, you can get rid of them quickly and effectively. Natural remedies like neem oil and diatomaceous earth can be highly effective, while chemical insecticides should only be used as a last resort. By taking preventative measures and regularly inspecting your plant, you can keep it healthy and pest-free for years to come.
