If you are growing dill, you may have encountered a pesky bug called the crusader bug. These insects have a distinct black and orange pattern and are known to feed on dill plants. If left untreated, they can cause significant damage to your crop. Here are some tips on how to get rid of crusader bugs on your dill plant.

Prevention is Key

The best way to combat crusader bugs is to prevent them from infesting your dill plant in the first place. You can do this by regularly inspecting your plants for signs of infestation and promptly removing any infected leaves or stems. Additionally, you can attract natural predators such as ladybugs or lacewings to your garden by planting flowers such as marigolds and cosmos.

Neem Oil

Neem oil is a natural insecticide that has been used for centuries to combat pests such as crusader bugs. You can purchase neem oil at most garden centers or online retailers. To apply, mix one tablespoon of neem oil with one gallon of water and spray directly onto your dill plant. Be sure to cover all parts of the plant, including the undersides of leaves.

Insecticidal Soap

Insecticidal soap is another effective and natural way to get rid of crusader bugs on your dill plant. You can purchase insecticidal soap at most garden centers or online retailers. To apply, mix one tablespoon of insecticidal soap with one gallon of water and spray directly onto your dill plant. Be sure to cover all parts of the plant, including the undersides of leaves.

Pyrethrin

Pyrethrin is a chemical insecticide derived from chrysanthemum flowers. It is a fast-acting insecticide that targets and kills crusader bugs on contact. You can purchase pyrethrin at most garden centers or online retailers. To apply, mix one tablespoon of pyrethrin with one gallon of water and spray directly onto your dill plant. Be sure to cover all parts of the plant, including the undersides of leaves.

Beneficial Nematodes

Beneficial nematodes are microscopic worms that are natural predators of crusader bugs. You can purchase beneficial nematodes from most garden centers or online retailers. To apply, mix the nematodes with water according to the package instructions and spray directly onto your dill plant. Be sure to cover all parts of the plant, including the undersides of leaves.
