1. Defining The Earwig: What Exactly Is An Earwig?
Earwigs, belonging to the order Dermaptera, are easily recognized by their cerci, or pincers, at the end of their abdomen. These insects are nocturnal and often found in moist environments. This section will dive into the earwig definition, their physical attributes, and basic biology.
1.1 The Earwig’s Physical Characteristics
Earwigs typically range from 5 to 25 mm in length and have elongated, flattened bodies. Their color varies from reddish-brown to black. A key feature is the pair of forceps-like appendages, or pincers, at the end of their abdomen. These pincers are used for defense, mating, and capturing prey. Earwigs also possess two antennae, six legs, and three distinct body sections: head, thorax, and abdomen. Some species have wings, while others are wingless.
1.2 Earwig Taxonomy and Diversity
There are over 1,000 species of earwigs worldwide, with about 22 found in the United States. These species vary in size, color, and habitat preference. Common earwig species include the European earwig (Forficula auricularia), which is widespread and often found in gardens, and the seaside earwig (Anisolabis maritima), which inhabits coastal areas. Each species has unique behaviors and ecological roles.
1.3 Earwig Life Cycle: From Egg To Adult
Earwigs undergo incomplete metamorphosis, which means they have three life stages: egg, nymph, and adult. The female earwig lays eggs in soil nests, carefully tending to them. After hatching, the nymphs resemble smaller versions of the adults, molting several times as they grow. The entire life cycle can take several months, depending on environmental conditions. Understanding this life cycle helps in targeting the most vulnerable stages for control.
2. Earwig Habitats: Where Do Earwigs Live?
Earwigs thrive in damp, dark places, making them common in gardens, under debris, and inside homes. Understanding their preferred habitats is crucial for effective prevention and control. This section details where earwigs live and why they choose these environments.
2.1 Outdoor Habitats: Gardens and Landscapes
In gardens, earwigs are often found under rocks, logs, mulch, and piles of leaves. They prefer these locations because they provide moisture and protection from predators. They are also attracted to decaying organic matter, which serves as a food source. In landscaped areas, earwigs may hide in flower beds, around the base of plants, and in compost piles.
2.2 Indoor Habitats: Homes and Buildings
Inside homes, earwigs typically seek out damp areas such as bathrooms, basements, and crawl spaces. They can enter through cracks in foundations, gaps around pipes, and openings in windows and doors. They may also be found in potted plants, under sinks, and in storage boxes. High humidity and moisture levels inside buildings create ideal conditions for earwig survival.
2.3 Geographical Distribution of Earwigs
Earwigs are found on every continent except Antarctica. Their distribution varies by species, with some being more common in temperate regions and others in tropical areas. In the United States, they are prevalent in the Pacific Northwest, the Midwest, and the Southeast. Climate and habitat availability play significant roles in their geographical spread.
3. Earwig Diet: What Do Earwigs Eat?
Earwigs are omnivorous insects, meaning their diet consists of both plant and animal matter.

Understanding their behavior patterns is essential for developing effective control strategies. This section delves into the nocturnal habits, social interactions, and reproductive behavior of earwigs.
4.1 Nocturnal Activity and Daytime Hiding
Earwigs are nocturnal, spending their days hiding in dark, moist places and emerging at night to feed. This behavior helps them avoid predators and harsh environmental conditions. During the day, they can be found under rocks, logs, mulch, and in crevices. Their nocturnal habits make them less visible to humans, often leading to unnoticed infestations.
4.2 Maternal Care and Nesting Habits
Female earwigs exhibit maternal care, a behavior uncommon among insects. They lay their eggs in soil nests and protect them from predators and environmental hazards. The female will clean the eggs and turn them regularly to prevent fungal growth. After the nymphs hatch, she continues to care for them until they are able to fend for themselves.
4.3 Aggregation and Pheromone Communication
Earwigs are known to aggregate, or gather in large numbers, in favorable habitats. This behavior is facilitated by pheromones, chemical signals that they use to communicate with each other. Pheromones help them locate food sources, nesting sites, and mates. Understanding pheromone communication can be useful in developing attractant-based control methods.
5. Earwig Myths and Facts: Separating Truth From Fiction
Earwigs are often the subject of myths and misconceptions. One common myth is that they crawl into people’s ears and lay eggs in their brains, which is entirely false. This section aims to dispel these myths and provide accurate information about earwigs.
5.1 Debunking the Earwig-In-Ear Myth
The myth that earwigs crawl into people’s ears is unfounded. While it is possible for an earwig to accidentally enter an ear, it is extremely rare and not their typical behavior. They do not lay eggs in ears or feed on brains. The name “earwig” is believed to have originated from the Old English word “ēarwicga,” meaning “ear creature,” but the exact reason for the name remains uncertain.
5.2 Addressing Concerns About Bites and Stings
Earwigs do not bite or sting. They have pincers that they use for defense and capturing prey, but these pincers are not strong enough to cause significant harm to humans. While they may pinch if threatened, the pinch is usually mild and harmless. There is no venom or poison associated with earwigs.
