Earwigs are a common problem for gardeners and homeowners alike. These insects can cause damage to plants and even find their way inside homes. While there are many chemical solutions available, some people prefer to use natural remedies. One such remedy is rosemary, which is believed to repel earwigs.

What are earwigs?

Earwigs are small insects with long bodies and pincers on their tails. They are typically brown or black in color and measure about 0.5 to 1 inch in length. Earwigs are nocturnal and prefer moist environments, making gardens and damp basements prime locations for them to nest.

Rosemary as a natural repellent

Rosemary is a fragrant herb that is known for its culinary uses, but it also has insect-repelling properties. Its strong scent is believed to deter pests such as earwigs. To use rosemary as a repellent, simply plant it in your garden or place sachets of dried rosemary around your home.

Scientific evidence

There have been some studies that suggest rosemary may be effective in repelling certain insects, including earwigs. One study published in the Journal of Agricultural and Food Chemistry found that rosemary oil was effective in repelling several types of insects, including cockroaches and mosquitoes. However, more research is needed to determine the effectiveness of rosemary specifically for repelling earwigs.

Other natural remedies for earwigs

In addition to rosemary, there are other natural remedies that can be used to repel earwigs. Some people swear by using diatomaceous earth or citrus peels to deter these pests. However, it’s important to note that not all natural remedies are effective and some may even have negative side effects.


While there may not be conclusive scientific evidence on the effectiveness of rosemary as a repellent for earwigs, many people swear by its use. It’s worth trying natural remedies like rosemary or diatomaceous earth before resorting to chemical solutions. By using natural methods, you can keep your garden and home free from pests without harming the environment or your health.
