What Are Earwigs?

Earwigs are intriguing insects that belong to the order Dermaptera. While they may look fierce with their formidable pincers on their hind abdomen, they are generally harmless to humans. Earwigs are characterized by their elongated bodies, flexible antennae, and membranous wings, although not all species can fly. They are nocturnal creatures that prefer dark, moist environments and can often be found hiding in crevices or under debris during the day. Despite their intimidating appearance, the vast majority of earwig species are not harmful to gardens or plants.

Lifestyle and Behavior

Earwigs lead interesting lives, which involve various behaviors and adaptations. Primarily nocturnal feeders, earwigs are known to be scavengers, feeding on a wide range of organic matter, including decaying plants, dead insects, and other small invertebrates. However, some species may also nibble on live plant material, especially if they are lacking alternative food sources. Earwigs are social insects and often gather in groups, which can be beneficial for gardeners as it makes trapping and removal easier if necessary.

Types of Earwigs That Cause Damage

While most earwig species are harmless to gardens, a small number can cause damage to plants, vegetables, or flowers. The most common culprits include the European earwig (Forficula auricularia), the striped earwig (Labidura riparia), and the ring-legged earwig (Euborellia annulipes). These particular species tend to be more herbivorous, feeding on live plant tissue, and can sometimes become a nuisance in gardens.

Signs of Earwig Infestation

If you suspect an earwig infestation in your garden, there are several signs to look out for. First, keep an eye on damaged plant parts, such as holes or notched edges on leaves and flowers. Additionally, earwigs may leave behind droppings, which resemble small black pellets, near plant stems or on the ground. Lastly, if you notice an unusually high number of earwigs scurrying around your garden, it could be an indication of an infestation.

Attracted to Certain Plants

Some plants are more attractive to earwigs, making them more likely to encounter these critters in your garden. Tender foliage, such as lettuce, roses, dahlias, and marigolds, can be particularly tempting for earwigs. Furthermore, plants with dense, moist environments, like ground covers or overgrown areas, may provide suitable hiding spots and attract earwigs.

Preferred Habitats

Earwigs typically thrive in areas with abundant organic matter and moisture. They are often found under mulch, stones, logs, and even in the soil. By creating moist and cluttered environments, gardeners inadvertently provide favorable habitats for earwigs. Understanding their preferred dwellings can help in managing their populations effectively.

How Earwigs Cause Damage

Earwigs can cause damage to plants through both their feeding habits and their nesting behaviors. When it comes to feeding, earwigs are attracted to tender leaves and flower petals. They use their pincers to scrape away plant tissue, leaving behind chewed edges or irregular holes. Additionally, earwigs often nest in the soil, which can lead to root damage if they tunnel near plant roots or disturb the soil structure.

Recognizing Earwig Damage

Differentiating earwig damage from damage caused by other pests can be challenging. However, some signs are indicative of earwig feeding. Look out for leaves that have irregular holes or notched edges, as this can suggest earwig activity. Similarly, flowers may show signs of petal damage or have areas that appear to be chewed. Close inspection of the affected plants, particularly during the evening or early morning hours when earwigs are most active, can help confirm their presence.

Preventing Earwig Damage

Prevention is key when it comes to managing earwig populations in your garden. By implementing various cultural control methods, physical barriers, and trapping techniques, you can significantly reduce the likelihood of earwig damage.

Cultural Control Methods

Maintaining good garden hygiene is an essential step in preventing earwig damage. Regularly remove any dead plant material, fallen leaves, or debris that could serve as hiding spots for earwigs. Additionally, minimize soil moisture by practicing proper irrigation techniques. Since earwigs are drawn to moist environments, adequately draining the soil can discourage their presence.

Physical Barriers

Protective physical barriers can be effective in deterring earwigs from accessing your plants. Consider installing collars around young, susceptible plants to prevent earwigs from climbing up the stems. You can use materials like cardboard or plastic cups with the bottoms removed and pushed into the soil around the stems. Additionally, using fine mesh screens or row covers can shield larger areas from earwig infestations.

Trapping and Removal

If you notice a significant earwig population in your garden, trapping and removing them can be an effective control method. Place traps near the affected plants using materials such as rolled-up newspaper or empty tuna cans filled with oil. The earwigs will be attracted to the trap and eventually drown or become trapped within. Regularly monitor the traps and dispose of the captured earwigs away from your garden to prevent their return.

Natural Predators of Earwigs

Fortunately, there are several natural predators that can help keep earwig populations in check. Birds, such as starlings and chickens, feed on earwigs and their eggs. Additionally, ground-dwelling beetles, spiders, and parasitic wasps also prey on earwigs. By attracting these beneficial predators to your garden through suitable habitats and diverse plantings, you can create a natural balance that discourages excessive earwig populations.

Chemical Control Methods

While chemical control methods should generally be a last resort, they can be effective in managing severe infestations or as a temporary measure. However, always prioritize the safety of yourself, other organisms, and the environment when considering chemical controls.

Insecticides for Earwigs

There are insecticides available that specifically target earwigs. Look for products containing active ingredients like carbaryl or permethrin. Follow the manufacturer’s instructions carefully when using insecticides and only apply them to the affected areas. It is important to note that insecticides may also harm beneficial insects and disrupt the natural balance in your garden.

Applying Insecticides Safely

To apply insecticides safely, always wear protective clothing, including gloves and long sleeves. Avoid spraying on windy days to prevent the chemical from drifting onto unintended areas. Additionally, refrain from using insecticides near bodies of water or on plants that are in bloom, as this can harm pollinators and other beneficial insects.

Organic Control Options

For those who prefer a more natural approach to pest control, several organic options can effectively manage earwig populations without relying on chemicals.

Diatomaceous Earth

Diatomaceous earth is one such organic option that can repel and control earwigs. This powdery substance is composed of tiny fossilized aquatic organisms that puncture the exoskeletons of insects, causing them to dehydrate and die. Apply diatomaceous earth around the base of plants or on affected areas to create a barrier that discourages earwigs.

Beneficial Insects

Introducing or attracting beneficial insects that prey on earwigs can be an eco-friendly control method. Ground beetles, lacewings, and parasitic wasps are all natural enemies of earwigs. By creating habitats that attract these beneficial insects, such as providing flowering plants and suitable shelter, you can encourage their presence and help reduce earwig populations.

Natural Repellents

Certain natural repellents can be used to deter earwigs from your garden. For example, a mixture of garlic and water sprayed on plants can discourage earwigs due to its strong scent. Similarly, essential oils like neem oil or peppermint oil, when diluted and applied to plants, can act as natural repellents. However, it is important to reapply natural repellents frequently, especially after rainfall, to maintain their effectiveness.


While earwigs may look intimidating, the majority of earwig species do not cause significant damage to plants, vegetables, or flowers in your garden. However, if you notice signs of earwig infestation or observe notable plant damage, it may be necessary to employ preventive measures or control methods. By implementing cultural practices, physical barriers, and natural control options, you can effectively manage earwig populations while maintaining a healthy and flourishing garden. Remember to always prioritize environmentally friendly methods, and consult with local experts or extension services for personalized recommendations. Happy gardening!
