What are earwigs, and how do they affect my garden?
Earwigs are small, elongated insects that are typically brown to dark brown in color. They are often recognized by their pincers, which are found on their rear end. In the garden, earwigs can be both beneficial and harmful. While they do feed on decaying plant matter and can help with decomposition, they are also known to damage live plants. They may chew on the leaves, flowers, and tender stems of a variety of plants, including vegetables and ornamental plants.
The presence of earwigs can lead to unsightly damage and may stunt the growth of your plants. Although they primarily feed at night, leaving behind distinctive holes in the foliage, they can quickly multiply if their populations are not controlled. Therefore, it is essential to implement preventive measures to keep them out of your garden to protect your plants from potential damage.
How can I prevent earwigs from entering my garden?
Preventing earwigs from entering your garden starts with proper garden maintenance. Keep the area tidy by removing debris like fallen leaves, grass clippings, and any decaying plant material where earwigs like to hide and breed. Additionally, ensure that your garden drains well and avoid overwatering, as earwigs are attracted to moist environments. Creating a well-aerated garden bed can also reduce moisture and make it less appealing to these pests.
Another effective method is to create physical barriers to keep earwigs at bay. Consider using copper tape around pots and garden beds, as the metal can deter them. You can also use diatomaceous earth, which can be sprinkled around plants, creating a barrier that earwigs will avoid. Regularly inspecting your garden for signs of earwig activity can help you stay ahead of a potential infestation.
Are there any natural predators of earwigs?
Yes, several natural predators can help control earwig populations in your garden. Birds, particularly insectivorous ones like wrens and sparrows, will readily eat earwigs. Frogs and toads also play a significant role in controlling earwig numbers as they feed on various insects, including earwigs, in your garden. Introducing or encouraging these predators can create a more balanced ecosystem and contribute to pest control.
In addition to birds and amphibians, beneficial insects like spiders and certain types of beetles can also help manage earwig populations. By fostering a biodiversity-friendly environment—such as planting native plants or reducing pesticide use—you can naturally attract these predators, which will assist in controlling earwig and other pest populations.

Mixing water with a few drops of these oils in a spray bottle can create a natural deterrent. Spray this mixture around the perimeter of your garden or directly on infested plants to keep earwigs at bay without using harsh chemicals.
Do earwigs bite humans or pets?
Earwigs are not known to bite humans or pets under typical circumstances. While they do have pincers, their primary use is for defense against predators and mating purposes. They are generally harmless and prefer to avoid larger animals. However, if handled or provoked, an earwig may pinch, but this will likely cause minimal discomfort and is not dangerous.
Nonetheless, while earwigs carry no significant health risks to humans or pets, some individuals may have allergic reactions to insect bites in general. It’s always best to exercise caution when handling any insects and to teach children to observe rather than capture or play with them to prevent any unnecessary contact with pests.
When is the best time to take action against earwigs?
The best time to take action against earwigs is during the early spring and late summer months when their populations tend to increase. In spring, female earwigs lay eggs in moist soil, leading to a larger population come summer. Consequently, preventative measures and monitoring should begin early to curb their development. Additionally, keeping your garden tidy during this time can help in effectively reducing their habitat.
During the late summer months, earwigs become more active as they search for food and may venture out of their hiding spots for foraging. At this point, monitoring and targeted control measures, whether natural or chemical, should be undertaken to prevent them from causing damage to your plants. Regularly checking your garden during these key times ensures you can effectively manage earwigs before they become a significant problem.
