Earwigs are a common household pest that can cause damage to plants and crops. And while there are many chemical pesticides available to control them, many people prefer to use natural methods to keep these insects at bay. One such method is using the lilac plant as a natural repellent for earwigs. But does lilac actually repel earwigs? In this article, we will explore the relationship between earwigs and lilacs and determine whether or not lilac is an effective repellent.

Earwigs and Their Habitat

Earwigs are small insects characterized by their long, slender bodies and pincers located on their rear end. They are nocturnal creatures that prefer dark, damp environments. Earwigs can be found in gardens, under rocks, in mulch beds, and even inside homes. They are attracted to moisture and are often found near water sources.

What Attracts Earwigs to Homes and Gardens?

Earwigs are attracted to moisture, so areas with high humidity levels, leaky pipes or faucets, and damp soil are likely to attract them. They also like to hide in dark crevices and cracks, so piles of debris or clutter provide a perfect hiding place for earwigs.

The Lilac Plant

The lilac plant is a popular ornamental shrub known for its fragrant blossoms. Lilacs come in a variety of colors, including purple, white, pink, and blue. They grow best in well-draining soil and full sun exposure.

The Potential Benefits of Having Lilacs in Your Garden

Lilacs have many benefits besides their beauty and fragrance. They attract pollinators like bees and butterflies to your garden. Additionally, they are known to repel some pests like aphids and spider mites. But the question remains: do they repel earwigs?

Does Lilac Repel Earwigs?

There is some evidence that suggests lilacs may repel earwigs. The scent of the flowers may be enough to deter these insects from entering your garden or home. However, there is no scientific evidence to support this claim.

Personal Experiences and Observations from Gardeners

Many gardeners swear by the effectiveness of lilacs as an earwig repellent. They claim that planting lilacs near windows or doors can prevent earwigs from entering your home. Others suggest placing cut lilacs near plants that are prone to earwig damage.

Other Natural Ways to Repel Earwigs

If you’re looking for alternative ways to repel earwigs, there are several natural remedies you can try:

  • Spray a mixture of equal parts water and dish soap on affected plants.
  • Use diatomaceous earth around the perimeter of your garden.
  • Place cedarwood essential oil-soaked cotton balls around your home or garden.

Best Practices for Preventing an Earwig Infestation

Prevention is key when it comes to controlling earwig populations. Here are some best practices you can follow:

  1. Reduce moisture levels around your home by fixing leaky pipes or faucets.
  2. Clear any debris or clutter around your garden.
  3. Keep plants well-pruned and trimmed.
  4. Avoid overwatering plants.


While there is no concrete scientific evidence that lilac repels earwigs, many gardeners believe it to be an effective deterrent. If you’re looking for a natural way to keep these pests away, planting lilacs may be worth a try. However, remember that prevention is key when it comes to controlling any pest population. By following best practices and using natural remedies when necessary, you can keep your home and garden free of earwigs and other unwanted insects.
