Cypress plants are a popular choice of landscaping for their evergreen foliage and attractive appearance. However, these plants are also susceptible to insect infestations, particularly by the crusader bug. These bugs can cause significant damage to cypress plants, leading to discoloration, leaf drop, and stunted growth. In this article, we will discuss how to get rid of crusader bugs on cypress plants.

Identify the Crusader Bug

The first step in getting rid of crusader bugs is to identify them correctly. Crusader bugs are small, oval-shaped insects that are about ¼ inch long. They are usually brown or green in color with distinctive white markings on their wings. You may also notice that they have a distinctive “V” shape on their head.

Natural Methods to Get Rid of Crusader Bugs

1. Prune Affected Branches

One natural method to get rid of crusader bugs is to prune affected branches. This will help remove the insects and prevent them from spreading to other parts of the plant. You should cut off any branches that have visible damage or signs of infestation.

2. Use Neem Oil

Another natural method is to use neem oil, which is a natural insecticide that is safe for use around pets and children. You can mix one tablespoon of neem oil in one gallon of water and spray it on the affected areas of the plant. This will help kill the crusader bugs and prevent them from coming back.

3. Use Beneficial Insects

You can also introduce beneficial insects like ladybugs, lacewings, and parasitic wasps into your garden. These insects prey on crusader bugs and can help control their population naturally.

Chemical Methods to Get Rid of Crusader Bugs

1. Insecticidal Soap

Insecticidal soap is a common chemical method used to get rid of crusader bugs. This soap works by suffocating the bugs and preventing them from breathing. You can mix one tablespoon of insecticidal soap in one gallon of water and spray it on the affected areas of the plant.

2. Pyrethrin

Pyrethrin is another chemical insecticide that is effective against crusader bugs. This insecticide works by targeting the nervous system of the insects, causing them to die. You can mix one tablespoon of pyrethrin in one gallon of water and spray it on the affected areas of the plant.
