Identifying Earwigs

Physical appearance

When it comes to identifying earwigs, their physical appearance is quite distinctive. These insects have long and slender bodies, ranging from half an inch to an inch in length. They are usually dark brown or black, with reddish-brown legs and pincer-like cerci at the end of their abdomens. One of the most unique features of earwigs is the pair of wings folded underneath their hardened forewings, which they use for protection.

Behavior patterns

Earwigs are primarily active during the night, making it challenging to spot them in action. They are known to be scavengers, feeding on both decaying plant matter and living plants. While they may occasionally munch on leaves and flowers, they tend to prefer tender plant shoots. Earwigs are particularly attracted to moist environments, which is why they are commonly found hiding in damp areas such as under pots, mulch, or rocks.

Signs of Earwig Damage

Leaf damage

One of the telltale signs of earwig damage is irregular-shaped holes in the leaves of your plants. Earwigs have a voracious appetite for leaves and can quickly devour large sections, leaving behind ragged edges. If you notice leaves with jagged holes or notches, it’s likely that earwigs are the culprits.

Plant growth disruption

Aside from feeding on leaves, earwigs can also disrupt the growth of your potted plants. They have a tendency to chew on young shoots, which can stunt their development or even prevent them from growing altogether. If you notice that your plants are struggling to grow or appear stunted despite proper care, earwig damage may be to blame.

Preventive Measures

Choosing appropriate pots

Selecting the right pots for your outdoor plants can play a significant role in preventing earwig infestations. Opt for pots made of materials such as plastic or ceramic, as these are less likely to provide hiding spots for these pests. Avoid using pots with drainage holes that are too large, as this can create an inviting environment for earwigs to hide and breed.

Using potting soil with proper drainage

Earwigs thrive in moist environments, so using potting soil with adequate drainage is crucial. Ensure that your potting mix is well-draining and not overly compacted. This will help prevent water from pooling and provide a less favorable habitat for earwigs. Adding materials such as perlite or vermiculite to your potting soil can improve drainage and discourage earwigs from settling in.

Creating a Protective Barrier

Copper tape

One effective method to protect your potted plants from earwig damage is to create a barrier using copper tape. Earwigs are repelled by the electrical charge that copper generates when it comes into contact with their bodies. Wrap the copper tape around the rim of the pot or place it around the base of your plants to create a deterrent for these pests.

Petroleum jelly barrier

Another simple yet effective technique is to create a barrier with petroleum jelly. Apply a generous layer of petroleum jelly around the rim of your pots or planters. This sticky barrier can prevent earwigs from climbing up and reaching your plants. Make sure to reapply the petroleum jelly periodically, especially after rainfall or watering.

Attracting Natural Predators

Encouraging birds and toads

Birds and toads are natural predators of earwigs and can provide effective control if they are attracted to your garden. To encourage their presence, create bird-friendly environments by placing bird feeders, bird baths, and birdhouses near your potted plants. Additionally, you can create toad-friendly habitats by incorporating shelter such as rocks and logs.

Introducing beneficial insects

Many beneficial insects, such as ground beetles and lacewings, are voracious eaters of earwigs. To attract these helpful insects to your garden, consider planting companion plants known to lure them, such as yarrow, dill, and cilantro. Alternatively, you can purchase beneficial insects from garden centers and release them near your potted plants to control earwig populations naturally.

Trap and Remove Methods

DIY traps

Creating your own traps can be an effective way to catch and remove earwigs from your potted plants. One simple DIY trap involves placing a shallow container filled with soapy water near the infested plants. Earwigs, attracted by the scent, will crawl into the container and drown. Regularly empty and refill the trap to ensure its effectiveness.

Handpicking and relocating

If you prefer a more hands-on approach, you can manually pick earwigs from your potted plants and relocate them to a more suitable habitat away from your garden. Remember to wear gloves to protect yourself from their pincers and handle them with care. You can release the captured earwigs in a wooded area or any other location away from desirable plants.

Herbal and Natural Repellents

Garlic spray

A natural deterrent that can help keep earwigs at bay is garlic spray. To make the spray, chop several cloves of garlic and steep them in boiling water. After cooling, strain the mixture and pour it into a spray bottle. Spritz the garlic spray onto the leaves and around the pots of your potted plants. The strong odor of garlic repels earwigs, preventing them from causing damage.

Neem oil

Neem oil is another effective herbal repellent that can safeguard your potted plants from earwig infestations. Dilute neem oil with water according to the instructions on the bottle and spray it onto the foliage of your plants. Neem oil not only repels earwigs but also acts as an insect growth regulator, disrupting their life cycle and preventing further damage.

Chemical Control Options


If all else fails and an earwig infestation becomes severe, there are insecticides available specifically formulated for earwig control. Look for insecticides containing ingredients such as carbaryl or permethrin. Follow the instructions on the label carefully when applying the insecticide, ensuring the safety of both your plants and the environment. Remember to use chemical control methods as a last resort and prioritize the use of natural, non-toxic alternatives.

Beneficial nematodes

Beneficial nematodes are microscopic roundworms that can be applied to the soil to combat earwig populations. These nematodes infect and kill earwig larvae, effectively reducing their numbers. Dilute beneficial nematodes in water according to the package instructions and apply them to the soil around your potted plants. This organic and environmentally friendly method can help control earwigs without harming other beneficial insects.

Regular Maintenance and Inspection

Pruning and removing debris

Regular maintenance is essential to prevent earwig infestations. Trim or prune any overgrown branches or foliage that may provide hiding spots for earwigs, ensuring good air circulation and visibility. Additionally, remove any fallen leaves, grass clippings, or organic debris around your potted plants, as these can create ideal habitats for earwigs to thrive.

Monitoring for early signs of infestation

Keep a close eye on your potted plants for early signs of earwig infestation. Regularly inspect the leaves and shoots for any damage or presence of earwigs. By catching the problem early, you can take swift action to prevent further damage and implement the appropriate control methods.

Special Considerations for Specific Plants

Sensitive plant varieties

Some plant varieties are particularly susceptible to earwig damage. If you have sensitive plants such as roses or dahlias in your outdoor potted garden, extra precautions may be necessary. Consider implementing a combination of protective barriers, natural predators, and herbal repellents specific to these plants to ensure their proper growth and protection from earwigs.

Container size and placement

The size and placement of your potted plants can also impact their vulnerability to earwig damage. Avoid overcrowding plants in small containers, as this can create a damp and inviting environment for earwigs. Adequate spacing between plants allows for better air circulation and reduces the risk of infestation. Additionally, consider repositioning your potted plants away from areas with excess moisture, such as downspouts or sprinkler systems.

By implementing these preventive measures, creating protective barriers, attracting natural predators, and utilizing trap and remove methods, you can protect your outdoor potted plants from earwig damage effectively. Remember to prioritize eco-friendly and natural control methods, maintaining a healthy and thriving garden. With a little diligence and care, you can enjoy your potted plants without the annoyance of earwig infestations. Happy gardening!
