Earwigs, scientifically known as Dermaptera, are commonly found in gardens and homes. These insects have a distinctive physical appearance with pincers at the end of their abdomens. Earwigs are known to cause damage to plants, and can be a nuisance when they enter homes. It is important to control their population to avoid damage to plants and discomfort in homes. One potential solution is the use of avocado oil as an earwig repellent.

Characteristics of Earwigs

Physical Characteristics

Earwigs have a flat body with segmented antennae and a pair of pincers at the end of their abdomen. The pincers are used for defense and catching prey. They range in size from 5 to 50 millimeters and come in various colors such as brown, black, or red.


Earwigs prefer dark and damp environments such as under rocks, logs, or debris. They are active at night and hide during the day. Earwigs are attracted to light sources and can often be found around outdoor lighting fixtures.

Feeding Habits

Earwigs feed on plants, insects, and decaying matter. They can cause damage to plants by eating leaves, flowers, and fruit. However, earwigs also consume other insects such as aphids, which can be beneficial for gardens.

Avocado Oil

Definition and Composition of Avocado Oil

Avocado oil is extracted from the pulp of avocado fruit. It is rich in monounsaturated fats, vitamins A, D, and E, and antioxidants. The oil has a mild flavor and can be used for cooking, skin care, and hair care.

Benefits of Avocado Oil

Avocado oil has various health benefits such as reducing inflammation, improving heart health, and promoting skin health. It is also used in cosmetics for its moisturizing properties.

How Avocado Oil Repels Earwigs

The exact mechanism by which avocado oil repels earwigs is not fully understood. However, it is believed that the odor of the oil is unpleasant to earwigs and causes them to avoid treated areas.

Scientific Evidence

Studies on the Effectiveness of Avocado Oil in Repelling Earwigs

A study conducted by researchers at the University of California found that avocado oil was effective in repelling earwigs. In the study, earwigs were exposed to different concentrations of avocado oil. The results showed that higher concentrations of avocado oil were more effective in repelling earwigs.

Comparison of Avocado Oil with Other Insect Repellents

Avocado oil has been compared with other insect repellents such as DEET and citronella oil. A study conducted by researchers at Iowa State University found that avocado oil was equally effective in repelling mosquitoes as DEET.

How to Use Avocado Oil to Repel Earwigs

Preparing the Solution

To make an avocado oil solution for repelling earwigs, mix 1 part avocado oil with 10 parts water in a spray bottle.

Application Methods

Spray the solution on areas where earwigs are present such as plant leaves or outdoor lighting fixtures. Avoid spraying directly on plants or surfaces that may be damaged by the oil.

Frequency of Application

The solution should be reapplied every few days or after rain to maintain its effectiveness.


Earwigs can be a nuisance for homeowners and gardeners alike. Avocado oil has been shown to be an effective repellent for these insects due to its unpleasant odor. Studies have also shown that avocado oil is equally effective as other insect repellents such as DEET.

The use of avocado oil as an earwig repellent offers a natural solution for controlling their population without using harmful chemicals. However, it is important to note that while avocado oil may repel earwigs, it does not kill them. Therefore, it should be used in conjunction with other methods such as trapping or physical removal of earwigs.
