Physical Characteristics and Identification
Earwigs are small, elongated insects that belong to the order Dermaptera. They are easily recognizable due to their unique physical features, which set them apart from other common household pests. Knowing how to identify earwigs is the first step in controlling these creepy crawlers, so let’s dive into their distinctive characteristics.
Earwigs generally measure between 5 to 25 millimeters in length, with some species being slightly larger. They have a flattened body, which allows them to easily navigate through tight spaces and crevices. Their color can vary from light brown to dark reddish-brown, depending on the species. Some earwigs may also have a slightly metallic sheen or yellowish markings on their body.
One of the most distinctive features of earwigs is their large, pincer-like cerci located at the end of their abdomen. These cerci are used for defense, capturing prey, and mating. In males, the cerci are generally more curved and larger than in females, making it relatively easy to distinguish between the sexes.
Earwigs have two pairs of wings, but they rarely use them for flying. The forewings, also known as tegmina, are short and leathery, serving as a protective cover for the delicate hind wings. The hind wings are membranous and fan-like, folding neatly beneath the tegmina when not in use. Although earwigs have fully developed wings, they prefer to crawl and hide in dark, damp places rather than fly.
Another notable feature of earwigs is their mouthparts, which are adapted for chewing. They have a pair of large, powerful mandibles that enable them to feed on a variety of plant and animal matter. Their antennae are long and segmented, typically consisting of 10 to 15 segments, which help them to detect food and navigate their surroundings.
To accurately identify an earwig, look for the following key features: a flattened, elongated body, pincer-like cerci at the end of the abdomen, short and leathery forewings, and long, segmented antennae. By familiarizing yourself with these characteristics, you will be better equipped to recognize and control earwig infestations in your home and garden.
Earwig Habitats and Life Cycle
Earwigs are found all over the world, with around 2,000 species known to exist. They are commonly found in temperate and tropical regions, living in a variety of habitats including forests, fields, gardens, and homes. Earwigs are nocturnal creatures, which means they are most active at night.
Earwigs prefer to live in dark, moist environments, such as under rocks, logs, and other debris. They also like to burrow in soil and mulch, and can often be found in flower beds, vegetable gardens, and other outdoor areas. Indoors, earwigs can be found in damp areas such as basements, bathrooms, and kitchens.
The life cycle of an earwig begins with the female laying eggs in the soil. The eggs hatch into nymphs, which look like smaller versions of adult earwigs but without wings. The nymphs go through several molts before reaching adulthood. The length of time it takes for an earwig to reach adulthood varies depending on the species and environmental conditions.
Once an earwig reaches adulthood, it will mate and lay eggs, starting the cycle over again. Earwigs usually live for about a year, although some species can live up to three years.
It’s important to note that earwigs are not harmful to humans, despite their scary appearance. They do not bite or sting, and are not known to transmit any diseases. However, they can be a nuisance if they infest homes or gardens in large numbers.
The Diet and Feeding Habits of Earwigs
Earwigs are often considered as pests due to their feeding habits, which can cause damage to plants. They are omnivorous, which means they eat both plant and animal matter. Earwigs primarily feed on decomposing plant material, such as fallen leaves and flowers, but they also eat insects, mites, and other small invertebrates.
Earwigs are known to be attracted to sweet and oily foods, such as fruits and vegetables, and can cause damage to crops like corn, lettuce, and strawberries. They may also feed on the buds, flowers, and leaves of plants, causing damage to the foliage and stunting the growth of the plant.
Earwigs are also known to feed on dead insects, which can be beneficial in reducing the population of other pests. However, they can also feed on live insects, such as bees and butterflies, which can have a negative impact on the ecosystem.
Despite their reputation as plant pests, earwigs can also have a positive impact on the environment. They play a role in breaking down organic matter, which helps to recycle nutrients in the soil. They may also feed on other pests, such as aphids and mites, which can help to control their populations.
Overall, while earwigs may be considered pests due to their feeding habits, they also play an important role in the ecosystem. It is important to take measures to control their populations when necessary, but also to appreciate their role in the environment.
Common Misconceptions About Earwigs
Earwigs are one of the most misunderstood and maligned insects in the world. Despite their relatively harmless nature, they have gained a reputation for being creepy and dangerous. In this section, we will explore some of the most common misconceptions about earwigs and provide accurate information to dispel these myths.
Myth #1: Earwigs crawl into people’s ears and lay eggs.
This is perhaps the most persistent and widespread myth about earwigs. While it is true that earwigs have a distinctive shape that resembles an ear canal, they do not have any particular interest in crawling into human ears. In fact, there are no documented cases of earwigs laying eggs in human ears. This myth likely originated from the old English word “earwicga,” which means “ear insect.”
Myth #2: Earwigs are dangerous and can bite or sting humans.
While earwigs do have pincers or forceps on their abdomen, they are not dangerous to humans. These pincers are primarily used for defense against predators and for mating. Earwigs do not have venom or poison, and they do not bite or sting humans.
Myth #3: Earwigs are nocturnal and only come out at night.
While earwigs are primarily active at night, they are not strictly nocturnal. Earwigs are also active during the day, especially in cool or overcast weather. They are attracted to dark, damp places, so you may see them more often at night in areas like basements or crawl spaces.
Myth #4: Earwigs are harmful to plants and crops.
While earwigs do feed on plants and can cause damage to crops, they are not usually a significant threat to plant health. Earwigs primarily feed on decaying plant matter, so they are more likely to be found in compost piles or areas with dead plant material. In some cases, earwigs may feed on live plant tissue, but this is usually only a problem in areas with high earwig populations.
Myth #5: Earwigs can fly.
Earwigs do not have wings and cannot fly. They are capable of crawling and climbing, but they are not able to fly or jump.
By understanding the facts about earwigs and dispelling these common myths, you can better protect your home and garden from these harmless insects.
Signs of an Earwig Infestation

Earwig Predators and Natural Enemies
Earwigs have a number of natural predators and enemies that help to keep their populations in check. Some of the most common predators of earwigs include birds, toads, and other small animals that feed on insects. These predators are attracted to the scent of earwigs and will often seek them out as a food source.
In addition to birds and toads, there are a number of insects that prey on earwigs. One of the most effective of these predators is the centipede. Centipedes are known to hunt and eat a wide variety of insects, including earwigs. They are particularly effective at controlling earwig populations in areas where other predators are scarce.
Other insects that prey on earwigs include spiders, ground beetles, and ants. These predators are attracted to the same habitats as earwigs and will often feed on them when they come into contact. Some species of ants are known to attack and kill earwigs, while others simply feed on their eggs and young.
In addition to natural predators, earwigs also have a number of natural enemies that help to control their populations. One of the most effective of these enemies is a type of parasitic wasp known as the earwig parasite. This wasp lays its eggs inside the bodies of earwigs, where they hatch and feed on the earwig’s internal organs. Eventually, the larvae emerge from the earwig’s body and spin cocoons in the soil, where they pupate and develop into adult wasps.
Overall, the presence of natural predators and enemies is an important factor in controlling earwig populations. By working together, these organisms help to maintain a balance in the ecosystem and prevent earwigs from becoming a nuisance or causing damage to crops and gardens.
The Impact of Earwigs on Human Health
