Earwigs are creepy-crawly bugs that can invade gardens, flower beds, and even homes. These pests have a notorious reputation for damaging plants and causing fear and disgust among people. If you’re looking for a natural solution to keep earwigs at bay, you might have heard about using peppermint as a repellent. But does peppermint really work against earwigs? In this article, we’ll explore the science behind peppermint as a natural repellent and how to use it effectively.

Earwigs and their habits

Before we dive into the benefits of peppermint, let’s take a closer look at earwigs and their habits. Earwigs belong to the Dermaptera order of insects and are characterized by their elongated bodies, pincers, and flexible wings. They are mostly active at night and are attracted to dark, damp places such as under rocks, mulch, or debris.

Earwigs feed on plants, fruits, and other insects. While they can help control other pests like aphids or mites, earwigs can also cause significant damage to crops, flowers, and ornamental plants. Moreover, earwigs can enter homes through cracks or gaps in doors or windows, becoming a nuisance for homeowners.

Peppermint as a natural repellent

Peppermint is an aromatic herb that has been used for centuries for its medicinal properties and pleasant scent. Peppermint contains menthol, which gives it a cooling sensation and a distinct aroma that can repel insects like mosquitoes or ants. But does peppermint work against earwigs?

According to scientific studies, peppermint oil has shown significant insecticidal activity against various pests including mosquitoes, ants, and termites. Peppermint oil contains compounds like limonene or eucalyptol that affect the nervous system of insects, causing them to avoid the treated area.

How to use peppermint to repel earwigs

If you want to use peppermint as a natural repellent against earwigs, there are several ways to do it. One option is to plant peppermint in your garden or flower bed. The strong scent of peppermint can deter earwigs from approaching your plants.

Another way is to use peppermint oil as a spray. You can make your own peppermint oil spray by mixing a few drops of peppermint oil with water in a spray bottle. Shake well before use and apply the spray on the affected areas such as plant leaves or soil.

Precautions to take when using peppermint

While peppermint is generally safe to use for humans and pets, there are some precautions you should take when applying it as a repellent. Peppermint oil can be irritating if it comes into contact with your eyes or skin, so always wear gloves and goggles when handling it.

Also, be careful not to overuse peppermint oil as it can harm beneficial insects like bees or butterflies. Use it sparingly and avoid spraying it directly on flowers or blooms.

Other natural remedies for earwig control

Apart from using peppermint as a repellent, there are other natural methods you can try to control earwig infestations. One option is to use diatomaceous earth – a powdery substance made from fossilized algae that can dehydrate insects when they come into contact with it.

Essential oils like lavender or tea tree oil are also known for their insect-repelling properties. You can mix a few drops of essential oil with water in a spray bottle and apply it on affected areas.


In conclusion, peppermint can be an effective natural repellent against earwigs thanks to its strong scent and insecticidal properties. Whether you choose to plant peppermint in your garden or use it as a spray, make sure to follow the precautions outlined in this article.

Remember that using natural remedies like peppermint may not provide an instant solution but rather prevent infestations in the long term. If you’re dealing with severe earwig problems, you may want to consider consulting a professional pest control service for further advice.
