Earwigs are a common garden pest that can cause significant damage to plants. These insects are known for their distinctive pincers at the end of their abdomen, which they use for protection and for catching prey. In this article, we will explore whether Roman Chamomile, a popular herb with many medicinal uses, can repel earwigs from your garden.

What is Roman Chamomile?

Roman Chamomile, also known as Chamaemelum nobile or English Chamomile, is a perennial herb that belongs to the Asteraceae family. It is native to western Europe and North Africa but has been cultivated in many other parts of the world. The plant has small daisy-like flowers with white petals and yellow centers.

Roman Chamomile has been used for centuries in traditional medicine and aromatherapy. It is known for its calming and soothing properties and is often used to treat anxiety, insomnia, and digestive issues. The essential oil extracted from the plant contains several bioactive compounds such as chamazulene, bisabolol oxide A and B, and farnesene.

Earwigs and their behavior

Earwigs are nocturnal insects that are typically found in gardens and outdoor areas with moist soil. They are attracted to dark, damp places such as under rocks, logs, or debris. Earwigs feed on plant material such as leaves, flowers, and fruits.

Earwigs can be a nuisance when they find their way into homes through cracks and crevices. They are attracted to warm and humid environments such as bathrooms, laundry rooms, and kitchens.

Does Roman Chamomile repel earwigs?

There is some evidence to suggest that Roman Chamomile can repel earwigs from your garden. The essential oil extracted from the plant contains compounds that have insecticidal properties. A study published in the Journal of Pest Science found that Roman Chamomile essential oil was effective in repelling two species of aphids and one species of spider mite.

To use Roman Chamomile to repel earwigs, you can either plant it in your garden or use the essential oil in a spray. Planting Roman Chamomile around the perimeter of your garden can create a barrier that will deter earwigs from entering. You can also make a spray by adding a few drops of Roman Chamomile essential oil to water and spraying it on plants or around areas where earwigs may be hiding.

Other natural remedies for repelling earwigs include diatomaceous earth, which is a powder made from fossilized algae that can dehydrate insects, and cedarwood oil, which has insect-repelling properties.


In conclusion, while there is some evidence to suggest that Roman Chamomile can repel earwigs from your garden, more research is needed to confirm its effectiveness. However, Roman Chamomile has many other benefits such as its calming properties in aromatherapy and its use in traditional medicine. If you are looking for a natural remedy for repelling earwigs, Roman Chamomile may be worth trying along with other natural remedies such as diatomaceous earth or cedarwood oil.
