Updated: December 21, 2022

Euonymus plants are popular among garden enthusiasts for their beautiful foliage and vibrant colors. Unfortunately, these plants are also a favorite target of borers – pests that can wreak havoc on your beloved shrubs. If you have noticed signs of borer infestation on your euonymus plants, it is important to act quickly to save them from further damage. In this article, we will discuss effective ways to get rid of borers on euonymus plants.

Identifying Borers on Euonymus Plants

Before we dive into the methods of getting rid of borers, it is important to know how to identify these pests. Borers are the larvae of various moth and beetle species that bore into the stems and trunks of euonymus plants. Signs of borer infestation include wilting leaves, yellowing foliage, and small holes in the bark. You may also notice sawdust-like particles around the base of the plant, which are left behind by the borers as they tunnel through the wood.

Removing Infested Branches

The first step in getting rid of borers is to remove any infested branches from your euonymus plant. Use pruning shears or a hand saw to cut off the affected branches at least 6 inches below the visible signs of borer damage. Be sure to dispose of the infested branches away from your garden to prevent the borers from spreading to other plants.

Applying Insecticides

There are several insecticides that can be effective in controlling borers on euonymus plants. Look for products that contain active ingredients such as cyfluthrin or permethrin. These chemicals work by killing the borers upon contact or ingestion. Follow the instructions on the label carefully when applying insecticides, as overdosing can harm your plant and cause more problems.

Using Natural Remedies

If you prefer to use natural remedies to get rid of borers on your euonymus plants, there are several options available. One effective method is to spray the plant with a mixture of neem oil and water. Neem oil is a natural insecticide that works by disrupting the feeding and reproductive cycles of pests. Another option is to use diatomaceous earth, which is a fine powder made from the fossilized remains of tiny aquatic organisms. Sprinkle diatomaceous earth around the base of your euonymus plant to create a barrier that will prevent borers from crawling up.

Maintaining Healthy Plants

The best way to prevent borer infestation on your euonymus plants is to maintain their overall health. Borers are attracted to weak and stressed plants, so make sure your euonymus is getting enough water and nutrients. Regular pruning can also help to keep your plant healthy and prevent the buildup of dead wood that can attract borers.


Borer infestations can be a frustrating problem for gardeners, but with the right approach, you can get rid of these pests and save your euonymus plants from further damage. Remember to keep an eye out for signs of borer activity, remove any infested branches, and apply insecticides or natural remedies as needed. By maintaining healthy plants, you can prevent future infestations and enjoy the beauty of your euonymus for years to come.
