How to Get Rid of Crusader Bugs on Urn Plant

Updated: July 8, 2023

The urn plant, also known as Aechmea fasciata, is a beautiful houseplant that is native to Brazil. With its striking silver-gray leaves and vibrant pink flower spike, it is a popular choice for indoor gardens. However, like any other plant, the urn plant can sometimes fall prey to pests. One such pest is the crusader bug, also known as Red Cross Shield Bug or Marmorated Stink Bug (Halyomorpha halys). These bugs can cause significant damage to the urn plant if left unchecked. In this article, we will discuss how to identify crusader bugs and provide effective methods to get rid of them.

Identifying Crusader Bugs

Crusader bugs are easily identifiable by their distinctive shield-shaped bodies and reddish-brown coloration with white markings. They have a triangular-shaped head and six legs. These bugs are about 1.5 cm long and emit a foul odor when disturbed. The nymphs of crusader bugs look similar but are smaller and lack wings.

Signs of Crusader Bug Infestation

If your urn plant is infested with crusader bugs, you may notice several signs:

  1. Leaf discoloration: Crusader bugs feed on the sap of the urn plant, causing yellowing or browning of leaves. This can lead to wilting and eventually leaf drop.
  2. Stippling marks: The bugs puncture the plant’s tissues while feeding, leaving behind small white or yellow stippling marks on the leaves.
  3. Black spots: As the infestation worsens, you may notice black spots on the leaves or stems. These are excrement marks left by the bugs.
  4. Foul odor: Crusader bugs release a pungent odor when threatened or crushed. If you notice an unpleasant smell near your urn plant, it may be a sign of an infestation.

Getting Rid of Crusader Bugs

To effectively eliminate crusader bugs from your urn plant, follow these steps:

Step 1: Isolate the Infected Plant

As soon as you spot a crusader bug infestation, it is crucial to isolate the infected plant from other healthy plants. This will prevent the bugs from spreading and causing further damage. Place the plant in a separate area away from other plants until the infestation is under control.

Step 2: Manual Removal

If the infestation is not severe, you can manually remove the bugs from your urn plant. Wear gloves to protect your hands from their foul odor. Carefully inspect the leaves, stems, and flowers for any bugs, nymphs, or eggs. Use a pair of tweezers or a cotton swab dipped in rubbing alcohol to remove and kill them. Be thorough in your inspection to ensure you remove all pests.

Step 3: Pruning Infested Parts

If the infestation is extensive and manual removal is not sufficient, consider pruning the heavily infested parts of your urn plant. Use clean and sterilized pruning shears to remove damaged leaves and stems. Dispose of the pruned parts safely, away from your other plants. This will help reduce the bug population and prevent further damage.

Step 4: Natural Predators

Introducing natural predators can be an effective way to control crusader bug populations. Ladybugs and lacewings are known to feed on these pests. You can purchase these beneficial insects from garden centers or online stores. Release them near your infected urn plant, and they will help reduce the bug population naturally.

Step 5: Homemade Bug Spray

A homemade bug spray can be an effective solution to control crusader bug infestations. To create a homemade spray, combine one teaspoon of dish soap with one quart of water. Transfer the mixture to a spray bottle and thoroughly spray your urn plant, focusing on the undersides of leaves and stems. The soap will suffocate the bugs and prevent them from feeding on your plant.

Step 6: Neem Oil Treatment

Neem oil is a natural pesticide derived from the seeds of the neem tree. It is highly effective against a wide range of pests, including crusader bugs. Dilute neem oil according to the instructions on the bottle and apply it to your urn plant using a spray bottle or brush. Neem oil works by disrupting the feeding and reproduction of pests, effectively controlling their population.

Step 7: Maintain a Healthy Growing Environment

To prevent future infestations, it is essential to maintain a healthy growing environment for your urn plant. Ensure proper watering practices, allowing the soil to dry out slightly between waterings. Overwatering can weaken the plant’s defenses and attract pests. Additionally, provide adequate light and airflow to discourage bug infestations.

In conclusion, crusader bugs can pose a threat to the health and beauty of your urn plant. However, by identifying the signs of infestation early on and taking prompt action, you can effectively get rid of these pests. Whether it’s manual removal, pruning infested parts, introducing natural predators, using homemade bug sprays, or applying neem oil treatments, there are several methods available to control crusader bug populations. By following these steps and maintaining a healthy growing environment, you can protect your urn plant from these unwanted invaders and enjoy its beauty for years to come.
