Earwigs, with their distinctive pincers and elongated bodies, are common household pests that can be a nuisance when they infest homes and gardens.

In this article, we will explore the signs of an earwig infestation, discuss preventive measures to keep them at bay, and provide effective treatment options. With this knowledge, homeowners can safeguard their homes and gardens from earwig infestations and maintain a pest-free environment.

Signs of an Earwig Infestation:

Recognizing the signs of an earwig infestation is crucial for early detection and effective treatment. Common signs include:
Sightings: Earwigs are nocturnal insects, so if you notice them during the day, especially in large numbers, it may indicate an infestation.
Damage to plants: Earwigs are known to feed on plant foliage and flowers. If you notice chewed leaves or damaged blossoms, it could be a sign of their presence.
Shiny, dark excrement: Earwigs leave behind small, black, or dark-colored excrement that resembles pepper or coffee grounds. These droppings are often found near their hiding spots.
Damage to structures: In rare cases, earwigs may enter homes and cause damage to fabrics, paper products, or even electrical wiring.

Prevention Tips for Earwig Infestations:

Taking preventive measures can help reduce the risk of earwig infestations. Here are some effective prevention tips:
Remove debris: Clear away leaf litter, fallen branches, and other debris from your yard as they provide hiding spots for earwigs.
Create a dry environment: Earwigs are attracted to moisture, so address any areas of excessive dampness or standing water around your home. Improve drainage and fix leaks promptly.
Trim vegetation: Keep plants, shrubs, and trees trimmed away from your home’s foundation, as they can serve as bridges for earwigs to enter your house.
Minimize outdoor lighting: Bright lights can attract earwigs. Consider using yellow or sodium vapor bulbs or keeping outdoor lights off when not needed.
Seal entry points: Use caulk or weatherstripping to seal gaps and cracks in windows, doors, and utility openings to prevent earwigs from gaining access to your home.
Install door sweeps: Place door sweeps on exterior doors to create a barrier that prevents earwigs from entering.

Natural Treatment Methods:

If you discover an earwig infestation, several natural treatment methods can help eliminate them. Here are some effective options:
Traps: Place rolled-up wet newspapers or cardboard traps in areas where you have seen earwigs. They will seek shelter in the damp areas, making it easier to collect and remove them in the morning.
DIY oil spray: Make a natural spray by combining water and a few drops of essential oils such as lavender, citrus, or peppermint. Spray this mixture directly on the earwigs to suffocate and kill them.
Dish soap solution: Mix water with a small amount of dish soap and spray it on earwigs. The soap will coat their bodies and interfere with their ability to breathe, effectively killing them.
Diatomaceous earth: Sprinkle food-grade diatomaceous earth around your home and garden, paying attention to areas where earwigs are active. The fine particles in diatomaceous earth scratch the exoskeleton of earwigs, leading to dehydration and eventual death.

Chemical Treatments:

In severe cases or when natural methods are not sufficient, chemical treatments can be used to control earwig infestations. However, it is important to use them judiciously and follow the instructions provided by the product manufacturer. Here are some common chemical treatments for earwigs:
Insecticides: Select an insecticide labeled specifically for earwig control. Apply it according to the instructions, focusing on areas where earwigs are most active, such as cracks, crevices, and baseboards. Take precautions to protect yourself, other people, pets, and beneficial insects.

Professional Pest Control:

If the infestation persists or becomes unmanageable, it may be necessary to seek professional pest control services. Pest control experts have the knowledge, experience, and resources to effectively address earwig infestations. They can conduct a thorough inspection, identify the extent of the infestation, and implement targeted treatments. Professional pest control ensures the safe and efficient elimination of earwigs, giving homeowners peace of mind.

Regular Monitoring and Maintenance:

To prevent future earwig infestations, regular monitoring and maintenance are crucial. Keep an eye out for any signs of earwigs, such as sightings or damage to plants. Implement preventive measures consistently, including maintaining a dry environment, sealing entry points, and practicing good yard and garden maintenance. Regularly inspect your home’s exterior and address any issues promptly to minimize the risk of earwigs finding their way inside.


Early detection, prevention, and effective treatment methods are key to controlling earwig infestations. By recognizing the signs of an earwig infestation, implementing preventive measures, and utilizing natural or chemical treatments when necessary, homeowners can successfully eliminate these pests. Regular monitoring, maintenance, and seeking professional assistance, if needed, will help ensure a pest-free environment and protect homes and gardens from the nuisances caused by earwigs.
