Understanding Earwigs

Physical Description

Earwigs are small insects that belong to the order Dermaptera. They are characterized by their elongated bodies, flattened appearance, and pincer-like appendages known as cerci at the tip of their abdomen. These cerci are what give earwigs their notorious reputation, but contrary to popular belief, they do not pose a threat to humans. Earwigs are typically dark brown or black in color, and they measure around 1 inch in length. They have two pairs of wings, with the hind wings being shorter and folded beneath the forewings when at rest.

Lifecycle and Habits

Earwigs undergo incomplete metamorphosis, meaning they have three distinct life stages: egg, nymph, and adult. The lifecycle of an earwig typically spans about one year. Female earwigs lay eggs in the soil during the spring or early summer. These eggs hatch into nymphs, which resemble smaller versions of the adults. The nymphs go through a series of molts before reaching their adult stage. Adult earwigs are nocturnal creatures, primarily active during the night, and they seek shelter in dark and damp areas during the day. They are attracted to light sources and can infest homes and gardens if given the opportunity.

Earwigs and Plants

Feeding Habits

Earwigs are omnivorous creatures, meaning they feed on a variety of food sources. Although they primarily eat organic matter, such as dead insects, decaying plant material, and fungi, they are also known to consume living plants. Earwigs are particularly attracted to tender shoots, leaves, flowers, and fruits. They may also feed on seedlings, causing damage to young plants. While they do have the potential to cause harm to garden plants, it is important to note that earwig populations are usually not large enough to cause significant damage.

Types of Damage

When earwigs consume plant material, they leave behind distinctive feeding marks. Common signs of earwig damage include irregular holes in leaves, scalloped or notched edges on leaves, and partially eaten flowers or fruits. In severe infestations, earwigs may devour tender new growth or cause defoliation. However, it is important to note that many insect pests can cause similar types of damage, so it is essential to properly identify the culprit before implementing control measures.

Signs of Earwig Infestation

Visible Damage

The most obvious sign of an earwig infestation is the presence of visible damage on plants. As mentioned earlier, this can take the form of irregular holes, notched leaves, or partially eaten flowers or fruits. It is essential to inspect the affected plants thoroughly to determine if earwigs are indeed responsible for the damage or if it may be caused by another pest.

Presence of Earwigs

Another sign of an earwig infestation is the presence of actual earwigs in the garden. Since earwigs prefer dark and moist hiding spots during the day, you may need to conduct your inspection during the night. Look for earwigs under plant debris, mulch, rocks, or other objects in the garden. If you spot a significant number of earwigs, especially in close proximity to damaged plants, it is likely that they are responsible for the inflicted harm.

Protecting Plants from Earwigs

Natural Predators

One effective method of controlling earwig populations is by encouraging natural predators that feed on these insects. Birds, toads, frogs, and lizards are all known to consume earwigs. By creating an inviting habitat for these creatures in your garden, you can help keep earwig populations in check. Providing birdhouses, birdbaths, and suitable shelters for these natural predators can make your garden a less favorable environment for earwigs, reducing the likelihood of an infestation.

Cultural Methods

Implementing cultural methods can also help protect your plants from earwigs. By creating an unfavorable environment for these pests, you can deter them from infesting your garden. One technique is to practice good garden sanitation by removing any plant debris, fallen leaves, or decaying mulch, as these provide hiding spots for earwigs. Regularly turning over the soil can also help expose their eggs and disrupt their lifecycle. Additionally, reducing excess moisture in your garden can make it less appealing to earwigs, as they prefer damp areas.

Physical Barriers

Using Traps

Traps can be an effective way to physically capture earwigs and reduce their numbers. There are several types of traps you can use in your garden to catch earwigs. One popular method is to place rolled-up newspaper or dampened cardboard in infested areas. Earwigs seek shelter in these dark and moist areas, and you can simply collect and dispose of the traps in the morning. Another option is using shallow containers filled with vegetable oil or soapy water, as earwigs will be attracted to the liquid and eventually drown. Regularly checking and emptying the traps will help keep the earwig population under control.

Applying Mulch

Applying a layer of mulch around your plants can act as a physical barrier against earwigs. However, it is important to choose your mulch wisely, as certain materials may actually attract earwigs. Avoid using wood chips or straw, as earwigs are attracted to these organic materials. Instead, opt for materials like gravel or diatomaceous earth, which can deter earwigs from accessing your plants. Additionally, keeping the mulch at a distance from the plant stems can prevent earwigs from using it as a pathway to reach your plants.

Creating Barriers

Creating physical barriers around your plants can also prevent earwigs from reaching them. Using sticky traps or barriers coated with petroleum jelly can deter earwigs from crawling up plant stems. You can wrap the base of susceptible plants with sticky tape or apply petroleum jelly to bands of plastic or cloth. This prevents the earwigs from climbing up and reaching the foliage. Regularly inspecting and replacing the barriers is crucial to maintain their effectiveness.

Chemical Control

Earwig-Specific Insecticides

In situations where natural predators and cultural methods are not sufficient, you may consider using specific insecticides targeting earwigs. There are several earwig-specific insecticides available on the market, which contain active ingredients such as spinosad or pyrethrins. These insecticides can be applied directly to plants or in areas where earwigs are commonly found. As with any pesticide, it is important to read and follow the manufacturer’s instructions carefully, including proper application rates and timing. It is also advisable to exercise caution when using chemical control methods, as they can harm beneficial insects and disrupt the natural balance of your garden ecosystem.

General Insecticides

If earwig infestations are severe or if you are dealing with multiple pest problems, a general insecticide may be necessary. In this case, it is important to choose an insecticide that is labeled for use on the specific plants you are treating and follow the instructions provided. Be mindful that general insecticides can harm beneficial insects and should be used as a last resort. Whenever possible, it is always preferable to pursue more environmentally-friendly methods of control.

Garden Maintenance

Removing Hiding Spots

Regular garden maintenance plays a crucial role in reducing earwig populations. By removing or minimizing potential hiding spots, you can discourage earwigs from taking up residence in your garden. Prune overgrown vegetation, trim tall grasses, and remove plant debris regularly. By maintaining a tidy garden, you provide fewer opportunities for earwigs to hide and breed.

Reducing Moisture

Since earwigs are attracted to moisture, reducing excess moisture in your garden can be an effective control measure. Avoid overwatering your plants and ensure proper drainage. Consider using methods like drip irrigation to deliver water directly to the plant roots, instead of overhead watering, which can create damp conditions that are ideal for earwigs. Additionally, avoid watering in the evening, as this can leave your plants damp throughout the night, providing an attractive environment for earwigs.

Integrated Pest Management


Monitoring your garden regularly is an essential component of integrated pest management. By keeping a watchful eye on your plants, you can detect early signs of pest infestations, such as earwig damage. Regularly inspect your plants for any feeding marks, chewed leaves, or other signs of earwig activity. Monitoring allows you to take proactive measures before the pest population becomes too large to control effectively.

Selective Control

Integrated pest management encourages the use of selective control methods that target the specific pest while minimizing harm to beneficial insects and the environment. When dealing with earwigs, selective control measures can include traps, physical barriers, cultural methods, or even hand-picking the pests from plants if their population is small. By adopting a selective approach, you can effectively manage earwigs while preserving the delicate balance of your garden ecosystem.

Earwig-Resistant Plants

Plant Selection

Choosing plants that are naturally less attractive to earwigs can help minimize the risk of infestations. While no plant is entirely resistant to earwigs, some species are more likely to be targeted than others. For instance, plants that have hairy or tough leaves, such as rosemary or lavender, are generally less appealing to earwigs. Conduct research or consult with local gardening experts to identify plants that are known to be less susceptible to earwig damage in your region.

Companion Planting

Companion planting involves strategically placing certain plants together to provide mutual benefits, such as pest control. Some companion plants are known to repel or deter earwigs, helping to protect neighboring plants. For example, planting calendula, marigolds, or nasturtiums alongside susceptible plants can help repel earwigs due to their strong aromas. Additionally, planting insectary plants, which attract beneficial insects that prey on pests, can create a more balanced and dynamic ecosystem in your garden.


While earwigs have the potential to cause damage to plants and gardens, they are generally not a severe threat. By understanding their physical description, lifecycle, and feeding habits, you can proactively protect your plants from earwig infestations. Implementing a combination of natural predators, cultural practices, physical barriers, and, if necessary, selective chemical control can help keep earwig populations in check. Regular garden maintenance, integrated pest management principles, and strategic plant selection further contribute to reducing the risk of earwig damage. With these strategies in place, you can cultivate a thriving garden while effectively managing earwig populations.
