What Are Earwigs?


Earwigs are small insects characterized by their elongated bodies, distinctive pincers (cerci), and membranous wings folded underneath their abdomen. Despite their somewhat intimidating appearance, they are not harmful to humans in general.

Earwigs belong to the order Dermaptera, and their name originates from the old English term “eare-wicga,” which means “ear insect.” This name has led to a common misconception that earwigs crawl into human ears, but this is actually a rare occurrence and not a common behavior of these insects.

These insects are typically around ⅜ to 1 inch in length, with dark brown to reddish-brown coloring. They have a flattened body shape, which allows them to easily navigate through tight spaces. One of the most distinctive features of earwigs is the pair of forceps-like pincers located at the tip of their abdomen, called cerci. These pincers are used killing earwigs for various purposes, including defense, capturing prey, and mating rituals.

Earwigs are primarily nocturnal creatures, which means they are most active during the night. They are omnivores, feeding on a variety of plant materials, mostly dead leaves, insects themselves, and decaying organic matter. Their diet can include aphids, mites, small insects, and even certain plants. This makes them both scavengers and potential predators in the ecosystem.

Earwig Infestations: Lifecycle of an Earwig


The lifecycle of an earwig involves several stages, each contributing to the growth and development of these intriguing insects. Here’s an overview of the lifecycle of an earwig:

Egg Stage

The lifecycle of an earwig begins with the egg stage. Female earwigs lay their eggs in hidden, moist areas, such as in cracks in the soil or under plant debris. The eggs are usually small, oval-shaped, and white in color. Depending on the species and environmental conditions, the eggs hatch within a couple of weeks.

Nymph Stage

After the eggs hatch, young earwigs, known as nymphs, emerge. Nymphs resemble smaller versions of adult earwigs but lack wings. They have a soft exoskeleton that gradually hardens as they molt, shedding their skin multiple times to accommodate their growing bodies. Nymphs are usually pale in color and become darker as they mature.

Juvenile Development

As nymphs grow, they go through several instars, or developmental stages, each characterized by a molt. During a few drops these molts, the nymphs shed their old exoskeleton to reveal a new one underneath. With each molt, they become larger and more closely resemble adult earwigs.

Adult Stage

Once nymphs have gone through enough molts and reached a certain size, they enter the adult stage. Adult earwigs possess the distinctive features that define their species, such as the elongated body, pincers (cerci), and membranous wings. These wings are folded underneath their abdomen when at rest. Adults are fully equipped for reproduction and play a crucial role in the continuation of the earwig lifecycle.


Earwigs engage in complex courtship rituals before mating. Male earwigs use their pincers to grasp onto females, and in some species, they engage in a gentle tug-of-war. Once mating is successful, females lay eggs in hidden, damp or moist locations, ensuring their protection and viability. The female earwig cares for her eggs and nymphs, guarding them until they hatch.

The entire lifecycle from egg to adult can span a few months, depending on factors such as species, temperature, and available resources. In warmer climates, earwigs may go through their lifecycle more quickly due to accelerated development.
