Earwigs are a common garden pest that can cause damage to plants and vegetables. Finding natural remedies for pest control is becoming increasingly important as people become more aware of the potential harm chemical pesticides can cause to the environment and human health. Bay Laurel, also known as Laurus nobilis, is a plant that has been used for centuries in cooking and medicinal purposes. In this article, we will explore whether Bay Laurel repels earwigs and how it can be used as a natural pest control method.

What are Earwigs?

Earwigs are small insects with long, slender bodies and pincers on their rear end. They are typically brown or black in color and can range in size from ½ inch to 1 inch in length. Earwigs are nocturnal insects that hide during the day and come out at night to feed on plants, flowers, and fruits. They can also feed on other insects and decaying organic matter. While earwigs may not cause significant damage to plants, a large infestation can lead to stunted growth and distorted leaves.

What is Bay Laurel?

Bay Laurel is a small tree or shrub native to the Mediterranean region. It has dark green, glossy leaves that are commonly used in cooking to add flavor to soups, stews, and sauces. Bay Laurel leaves also have medicinal properties and have been used for centuries to treat various ailments such as headaches, digestive issues, and respiratory problems. The active compounds found in Bay Laurel include eucalyptol, cineole, and terpenes.

Does Bay Laurel Repel Earwigs?

Research studies have shown that Bay Laurel may have insecticidal properties that repel earwigs. A study published in the Journal of Pest Science found that essential oils derived from Bay Laurel had a significant repellent effect on earwigs. Anecdotal evidence from gardening experts and enthusiasts also suggests that planting Bay Laurel around the garden perimeter or using Bay Laurel leaves as a natural insecticide can help repel earwigs.

The exact mechanism behind why Bay Laurel repels earwigs is not fully understood. Some researchers believe that the strong scent of the plant may be responsible for deterring insects. Others suggest that the active compounds found in Bay Laurel may interfere with the nervous system of insects, making them less likely to feed on plants.

How to Use Bay Laurel for Pest Control

If you want to use Bay Laurel as a natural pest control method, there are several ways you can do so:

  • Planting Bay Laurel around the garden perimeter: Planting Bay Laurel around the border of your garden may help repel earwigs from entering your garden.
  • Using Bay Laurel leaves as a natural insecticide: Crushed Bay Laurel leaves can be sprinkled around plants or placed in small mesh bags and hung near plants to repel earwigs.
  • Making a Bay Laurel spray for indoor use: Boiling Bay Laurel leaves in water and straining the mixture can create a natural insecticide spray that can be used indoors to repel earwigs.

Other Natural Remedies for Earwig Control

While Bay Laurel may be effective at repelling earwigs, there are other natural remedies you can try if you have an infestation:

  • Diatomaceous earth: Diatomaceous earth is a powder made from fossilized diatoms that can be sprinkled around plants to kill earwigs.
  • Boric acid: Boric acid can be mixed with sugar and water to create a bait that earwigs will consume, leading to their death.
  • Essential oils: Essential oils such as peppermint oil or lavender oil can be mixed with water and sprayed around plants to repel earwigs.


In conclusion, Bay Laurel may be an effective natural pest control method for repelling earwigs. Research studies suggest that essential oils derived from Bay Laurel have a significant repellent effect on earwigs, while anecdotal evidence suggests that using crushed Bay Laurel leaves or planting the plant around the garden perimeter may help deter these pests. Before resorting to chemical pesticides, it’s important to try natural remedies like Bay Laurel or other natural methods like diatomaceous earth or essential oils. By using natural pest control methods, we can protect our plants and vegetables without harming the environment or our health.
