Earwig-Proofing Your Garden: Protecting Your Plants from Earwigs


Earwigs can be a common nuisance in gardens, as they feed on plants, flowers, and foliage. Protecting your garden from these pesky insects is crucial to maintaining healthy plants and preventing damage. By implementing effective earwig-proofing strategies, gardeners can create a hostile environment for earwigs and ensure the well-being of their plants. In this article, we will explore various techniques and preventive measures to protect your garden from earwigs. These methods range from habitat modifications to natural repellents and mechanical barriers, allowing you to enjoy a thriving, earwig-free garden.

Garden Cleanup and Maintenance:

Keeping your garden clean and well-maintained is an important step in preventing earwig infestations. Regularly remove fallen leaves, debris, and decaying organic matter from the garden. This eliminates potential hiding places and food sources for earwigs. Prune plants to increase airflow and sunlight penetration, reducing damp and shaded areas that are attractive to earwigs. Additionally, keep weeds under control, as they can provide hiding spots and serve as alternate food sources for earwigs.

Habitat Modifications:

Creating an unfavorable environment for earwigs is an effective way to deter them from infesting your garden. Consider the following habitat modifications:

Reduce moisture: Earwigs are attracted to moist environments. Avoid over-watering plants and ensure proper drainage in the garden. Water plants early in the day, allowing the foliage to dry before nightfall.
Increase sunlight: Earwigs prefer dark and shaded areas. Trim or thin out dense vegetation to allow more sunlight to reach the soil surface and lower plant leaves. This reduces the attractiveness of your garden to earwigs.
Mulch alternatives: Instead of organic mulch, consider using inorganic materials like rocks or gravel around susceptible plants. Organic mulch can provide hiding spots for earwigs, while inorganic materials make the environment less appealing to them.

Natural Repellents:

Certain plants and substances act as natural repellents to deter earwigs from your garden. Consider incorporating the following into your gardening routine:
Herbs with strong scents: Plant fragrant herbs such as lavender, mint, or rosemary around your garden. The strong scents of these plants can repel earwigs.
Garlic or onion sprays: Create a natural spray by steeping crushed garlic or onion in water. Strain the mixture and spray it on plants as a deterrent. The pungent odor can help keep earwigs at bay.
Essential oils: Apply a few drops of essential oils such as peppermint, lavender, or citrus onto cotton balls and place them near vulnerable plants. The strong aroma of these oils can repel earwigs.

Mechanical Barriers:

Creating physical barriers can help protect your plants from earwigs. Consider the following mechanical barriers:
Copper tape or wire: Surround the base of susceptible plants with copper tape or wrap copper wire around plant stems. Earwigs are repelled by the electrical charge produced when they come into contact with copper.
Diatomaceous earth: Sprinkle food-grade diatomaceous earth around the base of plants or create a perimeter around your garden. The sharp particles in diatomaceous earth can deter earwigs and other crawling insects by causing dehydration and damage to their exoskeletons.

Traps and Baits:

Trapping and baiting can help reduce earwig populations in your garden. Consider the following methods:
Rolled-up newspaper traps: Roll up damp newspaper and place it in areas where earwigs are commonly seen. In the morning, collect the newspaper and dispose of the trapped earwigs.
Moistened cardboard traps: Similar to newspaper traps, place dampened cardboard in strategic locations. Earwigs will seek shelter in the damp areas, making them easier to collect and remove.
Beer traps: Bury a small container, such as a shallow dish, in the ground near susceptible plants. Fill it with beer, which attracts earwigs. They will crawl into the container and drown. Check and empty the traps regularly.

Natural Predators:

Encouraging natural predators in your garden can help control earwig populations. Birds, frogs, toads, and ground beetles are natural predators of earwigs. Provide birdhouses or birdbaths to attract birds, and create suitable habitats for frogs and toads. Avoid using chemical pesticides that can harm these beneficial creatures.

Regular Monitoring and Inspection:

Regularly monitor your garden for signs of earwig activity. Check plants for chewed leaves or flowers, and inspect the soil surface for earwig eggs or nymphs. Conduct nighttime inspections using a flashlight, as earwigs are nocturnal and more active during the dark hours. Early detection allows for timely intervention and prevents infestations from spreading.


Protecting your garden from earwigs requires a combination of preventive measures and active management. By implementing strategies such as garden cleanup, habitat modifications, natural repellents, mechanical barriers, traps and baits, encouraging natural predators, and conducting regular monitoring, you can create a hostile environment for earwigs and safeguard your plants. A well-maintained garden with healthy plants is less attractive to earwigs, allowing you to enjoy the beauty of your garden without the presence of these unwanted pests.
