Earwigs are nocturnal insects that belong to the order Dermaptera. They are characterized by their elongated bodies, flattened appearance, and pincer-like appendages which they use for defense and mating. Earwigs are often found in damp, dark environments and can be a nuisance in gardens and homes.

Arruda, also known as rue, is a perennial herb that is native to Southern Europe and Western Asia. It has been cultivated for its medicinal properties for centuries and is often used in traditional medicine to treat various ailments.

The purpose of this article is to explore whether Arruda is an effective natural remedy for controlling earwigs and how it can be used to repel these pests.

What is Arruda?

Arruda is a small shrub that grows up to 60 cm in height. It has bluish-green leaves that are arranged in pairs along the stem and small yellow flowers that bloom in the summer months. The plant produces a strong, bitter odor that is characteristic of its essential oils.

Arruda has been used for centuries in traditional medicine as a remedy for various ailments such as menstrual cramps, digestive disorders, and respiratory infections. It was also believed to have protective properties against evil spirits and was often used in rituals and ceremonies.

Today, Arruda is still used in traditional medicine for its anti-inflammatory, antispasmodic, and diuretic properties. It is also used as a culinary herb in some parts of Europe and North Africa.

Do Earwigs Hate Arruda?

The hypothesis that Arruda repels earwigs is based on the plant’s strong odor and bitter taste. It is believed that these properties may be unpleasant to earwigs and deter them from entering areas where the plant is present.

There is limited scientific evidence to support the hypothesis that Arruda repels earwigs. While some studies have shown that certain essential oils derived from plants, including Arruda, have insecticidal properties, there is no conclusive evidence that these oils are effective against earwigs specifically.

Many people have reported success using Arruda to repel earwigs from their gardens and homes. Some have found that planting the herb around the perimeter of their garden or applying a solution made from its leaves can help deter earwigs from entering the area.

How to Use Arruda to Repel Earwigs

Preparing an Arruda Repellent

To prepare an Arruda repellent, you will need fresh leaves from the plant, water, and a spray bottle. Chop up the leaves into small pieces and place them into a container with water. Let the mixture sit for several hours or overnight before straining out the leaves and transferring the liquid to a spray bottle.

Applying the Repellent Around the House and Garden

To apply the repellent around your house or garden, simply spray it onto surfaces where earwigs are likely to enter or congregate, such as doorways, window sills, or around plants. Repeat this process every few days or after rain showers to maintain effectiveness.

Alternative Methods for Using Arruda to Repel Earwigs

In addition to preparing a spray solution, you can also plant Arruda around your garden or home as a natural barrier against earwigs. Alternatively, you can crush fresh leaves from the plant and sprinkle them onto surfaces where earwigs are present.

Other Natural Ways to Repel Earwigs

There are several other natural remedies that may help control earwig infestations, including diatomaceous earth, neem oil, and cedarwood oil. These substances work by either physically killing or repelling earwigs from treated areas.

While there is limited scientific research comparing the effectiveness of different natural remedies for controlling earwigs, anecdotal evidence suggests that some may be more effective than others depending on the specific situation.

Using natural methods for controlling pests like earwigs has several advantages over chemical pesticides, including reduced environmental impact, less harm to beneficial insects like bees, and fewer health risks for humans and animals exposed to treated areas.

However, natural remedies may be less effective than chemical pesticides in some cases and may require more frequent applications or alternative methods for maximum effectiveness.


In conclusion, while there is limited scientific evidence supporting the effectiveness of Arruda as an earwig repellent, many people have reported success using it in their gardens and homes.

Preparing an Arruda repellent involves chopping up fresh leaves from the plant and mixing them with water before spraying onto surfaces where earwigs are present or likely to enter.

Other natural remedies for controlling earwigs include diatomaceous earth, neem oil, and cedarwood oil.
