Updated: September 5, 2022

Curcuma plants are known for their beautiful flowers and foliage, but they can also attract unwanted pests. One of the most common pests that attack curcuma plants is crusader bugs. These bugs can cause significant damage to the plant if left unchecked. If you have noticed crusader bugs on your curcuma plant, don’t worry; there are ways to get rid of them.

Symptoms of Crusader Bug Infestation

Before we dive into the methods of getting rid of crusader bugs, it is essential to know the symptoms of a crusader bug infestation. Here are some common signs that your curcuma plant may be infested with crusader bugs:

  • Stunted growth
  • Yellowing leaves
  • Wilted or distorted leaves
  • Holes in leaves
  • Black or brown spots on leaves
  • Presence of tiny black bugs on the plant

If you notice any of these symptoms, it is essential to act quickly to prevent further damage.

Natural Methods of Getting Rid of Crusader Bugs

There are several natural methods that you can use to get rid of crusader bugs on your curcuma plant. These methods include:

1. Neem oil spray

Neem oil is a natural insecticide that can kill crusader bugs without harming your curcuma plant. Mix one tablespoon of neem oil with one quart of water and add a few drops of dish soap. Spray this mixture onto the affected parts of the plant, making sure to coat both sides of the leaves. Repeat this process every three days until the bugs are gone.

2. Garlic spray

Garlic has natural insecticidal properties that can repel crusader bugs. Crush a few garlic cloves and mix them with one quart of water. Let the mixture sit overnight and then strain it. Add a few drops of dish soap and spray the mixture onto the affected parts of the plant. Repeat this process every three days until the bugs are gone.

3. Diatomaceous earth

Diatomaceous earth is a natural powder that is made from the fossilized remains of tiny aquatic organisms. It can be sprinkled directly onto the affected parts of the plant to kill crusader bugs. The powder works by dehydrating the bugs, causing them to die. Make sure to wear gloves and a mask when applying diatomaceous earth, as it can irritate your skin and lungs.

Chemical Methods of Getting Rid of Crusader Bugs

If the natural methods do not work, you may need to resort to chemical sprays. These sprays contain synthetic insecticides that can kill crusader bugs quickly. However, they can also harm beneficial insects and pollinators, so use them with caution.

1. Pyrethrin spray

Pyrethrin is a natural insecticide that is derived from chrysanthemum flowers. It is effective against crusader bugs and other pests but breaks down quickly in sunlight. Follow the instructions on the label and spray the affected parts of the plant thoroughly.

2. Permethrin spray

Permethrin is a synthetic insecticide that is highly effective against crusader bugs. However, it can also harm beneficial insects and pollinators. Use permethrin spray as a last resort and follow the instructions carefully.

Prevention Tips

Prevention is always better than cure when it comes to pest infestations. Here are some tips to prevent crusader bugs from attacking your curcuma plant:

  • Keep your plant healthy by providing it with adequate sunlight, water, and nutrients.
  • Remove any dead or damaged leaves from the plant regularly.
  • Inspect new plants before bringing them home to make sure they are bug-free.
  • Quarantine any new plants for a few days to prevent the spread of pests.
  • Use companion planting to repel pests. Planting marigolds or chrysanthemums near your curcuma plant can deter crusader bugs.
