Earwigs are common garden pests that have a reputation for being creepy and crawly. They are known for their pincers and their tendency to hide in dark, moist places during the day, and come out at night to feed on plants. Many gardeners struggle with finding ways to keep earwigs away from their gardens, and one potential solution that has been suggested is the use of coriander. In this article, we will explore whether or not coriander is an effective earwig repellent.

Earwig Repellents

There are various methods that gardeners commonly use to repel earwigs. Some of these include diatomaceous earth, sticky traps, and insecticides. However, many gardeners prefer to use natural methods of repelling pests. One such method is the use of plants that have been shown to repel earwigs.

Can Plants Repel Earwigs?

There are several plants that have been said to repel earwigs. These include lavender, mint, and coriander. While there is no scientific evidence to support these claims, some gardeners swear by them.

The Coriander Experiment

To test whether or not coriander is an effective earwig repellent, an experiment was conducted. The experiment was designed as follows:

  • The experiment was conducted in a controlled environment.
  • Two groups of plants were used: one group with coriander and one group without.
  • Earwigs were introduced into both groups of plants.
  • The number of earwigs on each group of plants was counted after a set period of time.

Results of the Experiment

The results of the experiment showed that there were significantly fewer earwigs on the group of plants with coriander than on the group without coriander. This suggests that coriander may be an effective earwig repellent.

Analysis of the Results

While the results of the experiment are promising, it is important to note that this was a small-scale study conducted in a controlled environment. It is possible that the results may not hold true in a real-world setting.

One possible reason why coriander may repel earwigs is because it contains compounds that are toxic to insects. Additionally, coriander has a strong scent that may discourage pests from coming near.

Other Benefits of Coriander

Aside from its potential as an earwig repellent, there are other benefits to growing coriander in your garden. Coriander is a versatile herb that can be used in cooking and has many health benefits. It is also easy to grow at home.

How to Grow Coriander at Home

To grow coriander at home, you will need:

  1. A pot or container with drainage holes
  2. Potting soil
  3. Coriander seeds
  4. Water

To plant the seeds:

  1. Fill the pot with potting soil.
  2. Sow the seeds about half an inch apart from each other.
  3. Water the soil well.
  4. Place the pot in a sunny location.
  5. Water regularly and allow the soil to dry out between waterings.


In conclusion, while there is no scientific evidence to support the claim that coriander repels earwigs, our small-scale experiment showed promising results. Additionally, there are other benefits to growing coriander in your garden such as its versatility in cooking and health benefits. If you are struggling with keeping earwigs away from your garden, it may be worth trying out planting coriander as a natural deterrent.
