Effectiveness of bergamot as a repellent

Studies have shown that bergamot essential oil can repel a variety of insects, including mosquitoes, ants, and flies. While there is limited research on its effectiveness against earwigs specifically, anecdotal evidence suggests that it may be an effective repellent for these insects as well.

Mechanisms through which bergamot repels earwigs

The exact mechanisms through which bergamot repels earwigs are not fully understood. However, it is believed that the strong aroma of the oil masks the scent of plants that earwigs are attracted to, making them less likely to feed on them.

How to Use Bergamot to Repel Earwigs

Preparing bergamot oil and spray

To make a homemade bergamot spray, combine 10-15 drops of bergamot essential oil with 1 cup of water in a spray bottle.

For an even stronger solution, mix 10-15 drops of bergamot oil with 1 cup of vinegar instead.

Applying bergamot oil and spray

To apply the bergamot spray or oil, simply spray or dab it onto areas where you suspect earwig activity such as around doors or windowsills or directly onto plants that you want to protect.

Dos and don’ts when using bergamot as a repellent


  • Dilute the essential oil before using it topically
  • Test the solution on a small area first to ensure that it does not cause any adverse reactions
  • Reapply the spray or oil regularly as needed


  • Use undiluted essential oils directly on your skin
  • Overuse the solution as it may damage plants if used excessively

Other Natural Ways to Repel Earwigs

In addition to bergamot essential oil, there are several other natural remedies that can help repel earwigs:

Essential oils

Other essential oils such as peppermint, lavender, and tea tree oil have insecticidal properties and may help repel earwigs when applied topically or diffused into the air.

Diatomaceous earth

Diatomaceous earth is a fine powder made from fossilized algae that can be sprinkled onto soil or other surfaces where earwigs are present. The powder acts as an abrasive substance that cuts through an insect’s exoskeleton causing dehydration and death.


Cedarwood has long been used as a natural insect repellent due to its strong scent which masks the scent of plants that insects are attracted to.
