Earwigs are a common garden pest that can cause damage to plants and vegetables. While there are many chemical pesticides available on the market, some people prefer to use natural repellents to avoid exposure to harmful chemicals. One natural option that has gained popularity in recent years is juniper berry. In this article, we will explore whether juniper berry is an effective earwig repellent and how to use it safely.

What are Juniper Berries?

Juniper berries come from the juniper plant, which is a coniferous shrub or tree that is native to many regions of the world. The berries themselves are small and round, with a blue-black color and a strong aroma. They have been used for centuries in traditional medicine and as a flavoring agent in food and beverages.

Uses of Juniper Berries

Aside from their culinary uses, juniper berries have also been used for their medicinal properties. They contain compounds that have been shown to have anti-inflammatory, antiseptic, and antioxidant effects. They have also been used to treat digestive issues, respiratory infections, and skin conditions.

Properties and Chemical Composition

Juniper berries contain a variety of chemical compounds, including essential oils, tannins, flavonoids, and terpenes. The most abundant compound is alpha-pinene, which is responsible for the distinctive pine-like scent of the berries. Other compounds include limonene, myrcene, and sabinene.

The Effectiveness of Juniper Berry in Repelling Earwigs

There have been several scientific studies conducted on the effectiveness of juniper berry as an insect repellent. One study published in the Journal of Economic Entomology found that juniper berry essential oil was effective in repelling several types of insects, including mosquitoes and ticks. Another study published in the Journal of Pest Science found that juniper berry oil was effective in repelling aphids.

When it comes to earwigs specifically, there is limited research on the effectiveness of juniper berry as a repellent. However, anecdotal evidence suggests that it may be effective in keeping earwigs away from plants and crops.

Comparison with Other Natural Repellents

There are many natural repellents that are commonly used to repel insects, including essential oils like peppermint and citronella, as well as herbs like lavender and rosemary. While there is limited research comparing the effectiveness of these different repellents, some people may find that certain options work better for them than others.

Personal Experiences

Many people have reported success with using juniper berry as an earwig repellent. Some suggest using dried juniper berries or leaves around the garden or planting juniper bushes near crops to keep earwigs away. Others recommend using juniper berry essential oil diluted in water or carrier oil and spraying it onto plants or surfaces where earwigs are present.

How to Use Juniper Berry to Repel Earwigs

There are several ways to use juniper berry to repel earwigs from your garden or crops.

Essential Oil Application

To use juniper berry essential oil as a repellent, mix 10-20 drops of the oil with 1 cup of water or carrier oil (such as coconut or jojoba oil) in a spray bottle. Shake well before using and spray onto plants or surfaces where earwigs are present. Reapply every few days or after rain.

Dried Berries or Leaves Application

You can also use dried juniper berries or leaves around your garden or crops to repel earwigs. Simply scatter them around the area where you want to keep earwigs away.

Other Methods

Some people suggest planting juniper bushes near crops as a natural deterrent for insects like earwigs. Additionally, keeping your garden free of debris and weeds can help reduce areas where earwigs may hide.

Precautions and Possible Side Effects

While natural remedies like juniper berry are generally considered safe, there are some precautions you should be aware of when using them.

Possible Allergic Reactions

Some people may be allergic to certain compounds found in juniper berries or essential oil. If you experience any redness, itching, or swelling after using juniper berry as a repellent, discontinue use immediately.

Safety Measures When Handling Essential Oil

Essential oils can be potent and should be handled with care. Always dilute essential oils before applying them topically or spraying them onto plants. Keep essential oils out of reach of children and pets.

Dosage and Concentration Precautions

When using essential oils, it’s important to follow recommended dosage guidelines to avoid overexposure. Do not ingest essential oils unless under the guidance of a healthcare professional.


While there is limited research on the effectiveness of juniper berry specifically as an earwig repellent, anecdotal evidence suggests that it may be worth trying if you’re looking for a natural solution. As with any natural remedy, it’s important to use caution when handling essential oils and other concentrated substances. With proper use and precautions, however, juniper berry may provide a safe and effective way to keep earwigs away from your garden or crops.

Natural repellents like juniper berry can be a great alternative to chemical pesticides for those who want to avoid exposure to harmful chemicals. However, it’s important to remember that they may not work as well for everyone or in every situation. It’s always a good idea to try multiple options and see what works best for you.

As interest in natural remedies continues to grow, there may be more research conducted on the effectiveness of specific herbs and essential oils as insect repellents. Continued research could help identify new options for those looking for safe and effective ways to keep pests away from their gardens and crops.
