Earwigs are common pests that can wreak havoc on outdoor gardens and indoor spaces. While they do not pose a significant threat to humans or animals, they can cause damage to plants and crops, making earwig control essential for gardeners and homeowners. In recent years, cinnamon has emerged as a potential solution for repelling earwigs. But does it really work? In this article, we will explore the effectiveness of cinnamon as an earwig repellent.

What are Earwigs?

Earwigs are insects that belong to the Dermaptera order. They are characterized by their distinct pincers, which they use for defense and mating. Earwigs are nocturnal creatures that prefer dark, damp environments such as under rocks or in soil. They feed on a variety of insects, plants, and decaying organic matter. While they do not transmit diseases or bite humans, they can cause damage to plants by chewing on leaves and flowers.

Do Earwigs Hate Cinnamon?

Cinnamon is a spice that is commonly used in baking and cooking. It is derived from the inner bark of trees in the Cinnamomum family. Cinnamon has been used for centuries for medicinal purposes and has recently gained attention for its potential insect-repelling properties.

Research studies have shown that cinnamon oil can be effective in repelling several types of insects, including mosquitoes, ants, and bed bugs. However, there is limited research on its effectiveness against earwigs specifically.

Personal experiences from gardeners and homeowners suggest that cinnamon can indeed repel earwigs. Some have reported success by sprinkling cinnamon powder around the perimeter of their gardens or using cinnamon oil sprays on plants.

How to Use Cinnamon to Repel Earwigs

There are several ways to use cinnamon as an earwig repellent. One method is to sprinkle cinnamon powder around the areas where earwigs are present, such as garden beds or pots. This creates a barrier that the earwigs may avoid crossing.

Another option is to create a spray using cinnamon oil diluted with water or vinegar. This can be applied directly to plants or surfaces where earwigs are present.

It is important to note that while cinnamon is generally considered safe for humans and pets, it may cause skin irritation or allergic reactions in some individuals. It is also not recommended to apply cinnamon oil directly onto plants, as it may cause damage or burn the leaves.

Other Natural Solutions for Earwig Control

While cinnamon may be effective in repelling earwigs, there are other natural remedies that can also be used for earwig control. These include diatomaceous earth, neem oil, and citrus sprays.

Diatomaceous earth is a natural powder made from fossilized algae that can be sprinkled around plants to create a barrier against insects like earwigs. Neem oil is extracted from the neem tree and has insecticidal properties that can repel earwigs when applied to plants.

Citrus sprays made from lemon or orange peels can also be effective in deterring earwigs. Simply soak the peels in water overnight and then strain the mixture into a spray bottle for use on plants.

It is important to note that while these natural remedies may be safer than chemical pesticides, they may not be as effective in severe infestations.


In conclusion, cinnamon may indeed repel earwigs when used properly. However, more research is needed to determine its effectiveness compared to other natural remedies and chemical pesticides. When using cinnamon as an earwig repellent, it is important to take precautions and avoid direct contact with skin or plant leaves.

Overall, natural solutions like cinnamon can provide an eco-friendly alternative to chemical pesticides for gardeners and homeowners seeking to control earwig infestations. Future research may reveal more opportunities for using natural products like cinnamon in pest management strategies.
