Broccoli is a vegetable that is rich in vitamins and minerals. It has a distinctive green color and a unique taste that is often described as slightly bitter. Broccoli is a member of the cabbage family, which also includes cauliflower and brussels sprouts.

The purpose of this article is to explore whether broccoli can be used as a natural repellent for earwigs. We will examine the characteristics of earwigs and broccoli, as well as previous studies on using broccoli as an insect repellent.

Earwig Habits and Diet

Earwigs are omnivores that feed on both plants and animals. They are attracted to decaying matter, such as compost piles, as well as moist environments like mulch beds. Earwigs are also known to feed on fruits, vegetables, and flowers.

Broccoli Characteristics

Broccoli is a cruciferous vegetable that is high in fiber, vitamins, and minerals. It has a complex flavor profile that includes bitterness, sweetness, and nuttiness. Broccoli is also known to contain compounds that have anti-cancer properties.

Previous Studies

Previous studies have shown that some plants may have insect-repelling properties. For example, lavender has been shown to repel moths, while marigolds repel aphids. Some studies have also suggested that broccoli may have insect-repelling properties.

Broccoli as an Earwig Repellent

How Broccoli works as a Repellent

Broccoli contains compounds called glucosinolates, which give it its distinctive taste and smell. These compounds are known to have insecticidal properties and may repel certain insects, including earwigs.

Effectiveness of Broccoli

Studies on the effectiveness of broccoli as an earwig repellent have been limited. However, anecdotal evidence suggests that placing broccoli near plants may help deter earwigs from feeding on them.

Comparison with Other Repellents

There are many commercial insect repellents available on the market that claim to repel earwigs. These products typically contain synthetic chemicals that may be harmful to humans and the environment. Using broccoli as a natural repellent may be a safer and more eco-friendly alternative.

How to use Broccoli as an Earwig Repellent

Preparing and Applying Broccoli

To use broccoli as an earwig repellent, simply cut up some fresh broccoli into small pieces and place them near plants that are susceptible to earwig damage. Replace the broccoli every few days or when it starts to rot.

Preventive Measures

In addition to using broccoli as a repellent, there are other preventive measures you can take to reduce the risk of earwig infestation. These include removing decaying plant material from your garden, reducing moisture levels by watering plants in the morning instead of at night, and sealing cracks and crevices in your home where earwigs may enter.

Natural Remedies for Earwig Infestation

If you already have an earwig infestation in your home or garden, there are several natural remedies you can try to get rid of them. These include diatomaceous earth, which is a fine powder made from fossilized algae that dehydrates insects; neem oil, which is derived from the neem tree and has insecticidal properties; and sticky traps, which can be used to capture earwigs.


Earwigs are common pests that can cause damage to plants in your garden or home. While there is limited scientific evidence on the effectiveness of using broccoli as an earwig repellent, anecdotal evidence suggests that it may help deter these pests.

More research is needed to determine the effectiveness of using broccoli as an earwig repellent and how it compares to other natural or synthetic options.

Using broccoli as a natural repellent for earwigs may be a safe and eco-friendly option for those who want to avoid using synthetic chemicals in their home or garden pest control efforts. However, it should not be considered a foolproof solution and should be used in conjunction with other preventive measures for best results
