Earwigs are a common household pest that can cause damage to plants and property. They are known for their pincer-like appendages on their abdomen, which they use for defense and to capture prey. Many people turn to chemical insecticides to control these pests, but there are also natural methods available. One such method is using essential oils, like Ravensara, as a repellent. In this article, we will explore the properties of Ravensara essential oil and its effectiveness in repelling earwigs.

What is Ravensara?

Ravensara is a tree that grows in Madagascar and has been used for medicinal purposes for centuries. The plant’s scientific name is Ravensara aromatica, but it is also commonly known as clove nutmeg, or Madagascar nutmeg. Ravensara essential oil is extracted from the leaves of the tree and is known for its antiviral, antibacterial, and anti-inflammatory properties.

Extraction process of Ravensara essential oil

Ravensara essential oil is extracted through steam distillation. The leaves of the Ravensara tree are harvested and then steam is passed through them to release the essential oil. The oil is then collected and separated from the water and other impurities that were extracted along with it.

Chemical components of Ravensara essential oil

Ravensara essential oil contains several chemical components that contribute to its insect-repelling properties. These include limonene, eucalyptol, beta-pinene, alpha-pinene, and alpha-terpineol.

Repellent Properties of Ravensara

Studies have shown that Ravensara essential oil has insecticidal properties that make it an effective natural insect repellent. It works by disrupting the nervous system of insects and preventing them from feeding or reproducing.

How Ravensara repels insects in general

Ravensara essential oil repels insects by interfering with their sense of smell. Insects rely on their sense of smell to locate food sources and mates, so when they encounter a strong scent like Ravensara, they become disoriented and confused.

Specific research on Ravensara’s effectiveness against earwigs

A study published in the Journal of Agricultural and Food Chemistry found that Ravensara essential oil was effective in repelling earwigs. The study compared the effectiveness of ten different essential oils against earwigs and found that Ravensara was one of the most effective.

How to Use Ravensara to Repel Earwigs

There are several ways to use Ravensara essential oil as an insect repellent. One way is to dilute the oil with a carrier oil, such as coconut or jojoba oil, and apply it to areas where earwigs are likely to be found, such as around doors and windows.

Another method is to add a few drops of Ravensara essential oil to a diffuser or spray bottle filled with water and spray it around your home or garden. This method can also help repel other insects like mosquitoes and ants.

It’s important to note that essential oils should be used with caution as they can be toxic if ingested or applied directly to the skin. Always dilute essential oils before use and test for skin sensitivity before applying topically.

Other Natural Repellents for Earwigs

If you’re looking for alternative natural methods for repelling earwigs, there are several options available. Diatomaceous earth is a natural powder made from fossilized algae that can be sprinkled around your home or garden to repel insects like earwigs.

Another option is to plant herbs like mint or basil around your garden as these plants naturally repel insects like earwigs.

Comparison of effectiveness and safety of different natural repellents

When comparing different natural repellents for earwigs, it’s important to consider both their effectiveness and safety. While some methods like diatomaceous earth may be very effective at repelling insects, they can also be harmful if ingested or inhaled.

Essential oils like Ravensara may not be as effective as chemical insecticides but they are generally considered safe when used properly.


In conclusion, Ravensara essential oil has been shown to be an effective natural insect repellent, including against earwigs. By disrupting their sense of smell and nervous system, Ravensara can help keep these pests at bay without the use of harmful chemicals. However, it’s important to use essential oils with caution and consider alternative methods if you have concerns about safety or effectiveness.
