Earwigs are nocturnal insects that prefer to live in damp environments, such as under rocks or logs, in soil, or in mulch. They feed on decaying plant matter and can also damage live plants by chewing on leaves and flowers. To control earwig infestations, homeowners often use chemical pesticides or natural repellents.

Chemical pesticides are effective at killing earwigs, but they can also harm beneficial insects and may have negative effects on human health and the environment. Natural repellents, on the other hand, do not kill earwigs but instead deter them from entering an area. Some common natural repellents for earwigs include diatomaceous earth, cedar oil, and essential oils such as peppermint and lavender.

Does Cardamom Repel Earwigs?

Cardamom is a spice that comes from the seeds of a plant in the ginger family. It has a strong aroma and flavor and is commonly used in Indian cuisine. Some people have also used cardamom as a natural remedy for digestive issues, respiratory problems, and other ailments.

Research on the effectiveness of cardamom as an earwig repellent is limited. However, one study published in the Journal of Pest Science found that cardamom oil had a repellent effect on different species of stored-product insects, including one species of earwig. The study concluded that cardamom oil could be used as a natural alternative to chemical insecticides for controlling stored-product pests.

To use cardamom as an earwig repellent, you can try placing whole cardamom pods or ground cardamom near areas where earwigs are known to congregate, such as in your garden or around your home’s foundation. You can also mix cardamom oil with water and spray it onto surfaces to create a barrier that repels earwigs.

Benefits and Drawbacks of Using Cardamom as an Earwig Repellent

Using natural repellents like cardamom has several advantages over chemical pesticides. Natural repellents are generally safer for humans and the environment because they do not contain harmful chemicals. They also do not harm beneficial insects like bees or ladybugs, which are important for pollination and pest control.

However, there are some potential drawbacks to using cardamom as an earwig repellent. First, its effectiveness has not been extensively studied for this specific purpose. Second, while it may work well for some people, others may find that it does not work at all or has limited effectiveness.


In conclusion, while research on the effectiveness of cardamom as an earwig repellent is limited, some studies suggest that it may have some repellent properties for certain types of insects. If you are looking for a natural alternative to chemical pesticides for controlling earwig infestations, you may want to give cardamom a try. However, be aware that its effectiveness may vary depending on your individual situation. As always, it is important to consult with a pest control professional if you are experiencing persistent pest problems in your home or garden.
