Earwigs are common household pests that are known for their distinct appearance – long, slender bodies with pincers at the end. They are nocturnal insects that thrive in damp places and can be found in gardens, basements, and bathrooms. There are several methods used to repel earwigs, including the use of cedar oil. In this article, we will explore whether or not cedar oil is an effective earwig repellent.

What is Cedar Oil?

Cedar oil is extracted from the wood of cedar trees and has been used for centuries in traditional medicine and as a natural insect repellent. It has a pleasant scent and is commonly used in aromatherapy. Cedar oil contains compounds such as cedrol, thujone, and alpha-pinene that give it anti-inflammatory, antifungal, and insecticidal properties.

Does Cedar Oil Repel Earwigs?

Several studies have been conducted to evaluate the effectiveness of cedar oil in repelling insects, including earwigs. One study found that cedar oil was effective in repelling cockroaches, ants, and mosquitoes. However, there is limited research on the specific effectiveness of cedar oil against earwigs.

Despite the lack of scientific evidence, many homeowners report success in using cedar oil to repel earwigs. The pleasant scent of cedar oil can create a barrier that discourages earwigs from entering the home.

How to Use Cedar Oil to Repel Earwigs

To use cedar oil as an earwig repellent, follow these steps:

  1. Choose a high-quality cedar oil product.
  2. Apply a few drops of cedar oil onto a cotton ball.
  3. Place the cotton ball near areas where earwigs are commonly found, such as window sills or doorways.
  4. Replace the cotton ball every few weeks or as needed.

It is important to note that cedar oil should not be applied directly to the skin or ingested. It should also be kept out of reach of children and pets.

Other Natural Remedies for Repelling Earwigs

In addition to cedar oil, there are other natural remedies that can be used to repel earwigs. Diatomaceous earth is a powder made from fossilized marine organisms that can dehydrate and kill earwigs. Neem oil is derived from the neem tree and has insecticidal properties. Garlic spray can also be effective in repelling earwigs.

However, it is important to note that the effectiveness of these remedies may vary depending on the severity of the infestation and other environmental factors.


In conclusion, while there is limited scientific evidence on the effectiveness of cedar oil in repelling earwigs, many homeowners report success in using it as a natural repellent. It is a safe and eco-friendly alternative to chemical insecticides. When using cedar oil or any other natural remedy for pest control, it is important to follow safety precautions and consult with a professional if needed.
