Earwigs are small insects that are often found in dark, damp environments. They have a distinctive appearance, with elongated bodies and pincers on their rear end. While they are not harmful to humans, they can be a nuisance if they infest your home or garden. In this article, we will explore whether camphor can be used to repel earwigs.

Camphor is a white, crystalline substance that is derived from the wood of the camphor tree. It has a strong odor and is often used in natural remedies for a variety of ailments. One of the properties of camphor is its ability to repel insects.

Earwig Infestations

If you have an earwig infestation in your home or garden, there are some common signs to look out for. Earwigs are nocturnal insects, so they are most active at night. You may see them crawling around on surfaces or hiding in crevices during the day. They also leave behind small, black droppings that can be found near their hiding spots.

While earwigs are not harmful to humans, they can cause damage to plants and crops. They also have a reputation for crawling into people’s ears while they sleep, although this is a rare occurrence.

Camphor as a Repellent

Camphor has been used as an insect repellent for centuries. In traditional Chinese medicine, it has been used to repel mosquitoes and other biting insects. Many natural insect repellents on the market today contain camphor as an active ingredient.

Scientific studies have shown that camphor is effective at repelling a variety of insects, including mosquitoes, flies, and ants. While there is no specific research on camphor’s effectiveness against earwigs, it is believed that it may be able to repel them as well.

How to Use Camphor to Repel Earwigs

There are several ways to use camphor to repel earwigs. One method is to place camphor tablets or balls around your home or garden in areas where earwigs are likely to hide. You can also use camphor oil by diluting it with water and spraying it on surfaces or plants.

It’s important to note that camphor should be used with caution, as it can be toxic if ingested or inhaled in large amounts. Always follow the instructions on the packaging and keep camphor out of reach of children and pets.

Other Natural Remedies for Earwig Control

In addition to camphor, there are several other natural remedies that can be used to control earwig infestations. These include diatomaceous earth, which is a fine powder made from fossilized algae that can be sprinkled around your home or garden to kill insects. You can also try using citrus peels or essential oils like lavender or peppermint as a natural repellent.

It’s important to keep in mind that while natural remedies can be effective at controlling pests, they may not work as quickly or effectively as chemical pesticides.


In conclusion, camphor may be an effective natural remedy for repelling earwigs. It has been used for centuries as an insect repellent and has been shown to be effective against a variety of insects. However, it should be used with caution and always follow the instructions on the packaging.

There are also other natural remedies for earwig control that may be worth exploring. Ultimately, the best method for controlling pests will depend on your individual situation and preferences.
