In the mysterious world of insects, we often encounter creatures that spark curiosity—and sometimes fear—leading us to ask questions about their nature, role in the ecosystem, and potential danger to humans. Among these creatures is the earwig, a nocturnal visitor whose pincer-like appendages appear threatening. But is it truly dangerous? Does it pose the threat its strange appearance suggests?
Many have heard the myth that earwigs crawl into human ears and lay eggs, a terrifying thought for some. Others believe that its presence in a home is a sign of filth or neglect. Between myths and misconceptions, the truth remains clouded. In this article from teketrek. , we take you on an engaging scientific journey to answer the most frequently asked questions about the earwig—based on environmental studies and known behaviors—away from exaggerations and folklore.
Let’s explore everything you’ve ever wondered about this fascinating creature through a well-structured Q&A format that opens a new window into this tiny and intriguing world.
1. What is an earwig?
The earwig is a common name for an insect from the order Dermaptera, known for the pair of prominent pincers at the end of its abdomen. It’s called “earwig” due to an old myth about it entering human ears. It typically measures between 1.5 and 2.5 cm in length and has a flat, elongated body with a dark brown or black color. It’s a nocturnal insect that prefers warm and moist environments.
2. Is the earwig poisonous?
No, the earwig is not poisonous. Despite its intimidating appearance, it does not secrete any venom or harmful chemicals. Its rear pincers are used for defense or mating, not for injecting poison as some rumors suggest.
3. Do earwigs crawl into human ears?
This is one of the most widespread myths about the insect—and it is completely untrue. There is no scientific evidence that earwigs deliberately crawl into human ears. While they might hide in warm, moist places, entering a human ear would only happen accidentally, not as a natural behavior.
4. Do earwigs bite?
Earwigs do not have mouthparts capable of biting humans in a harmful way. However, they might use their pincers defensively if threatened, potentially causing a light, painless pinch. This rarely causes any injury or health issue.
5. What do earwigs eat?
Earwigs are omnivorous and feed on a variety of organic matter, including:
- Decaying plant material
- Small insects
- Insect eggs
- Fungi and mold
- Rotten fruits and vegetables
This diet can make them beneficial in gardens as they help clean up decomposing materials.
6. Where do earwigs live?
Earwigs prefer dark, damp environments such as:
- Under rocks or wood
- Among fallen leaves
- Inside wall cracks
- In flowerpots
- In humid areas like bathrooms or kitchens
These places provide the moisture and darkness they need to survive.
7. Can earwigs fly?
Yes, some earwig species have wings and can fly, but they rarely do so. Their wings are hidden and complex, and they usually prefer crawling to get around. Flight is considered a secondary trait in earwigs.
8. How can I get rid of earwigs?
To remove earwigs from your home or garden, consider the following steps:
- Reduce indoor humidity
- Seal cracks and wall gaps
- Remove decaying organic matter from the garden
- Use oil-based traps to lure them
- Apply mild insecticides if necessary
9. Do earwigs reproduce quickly?
Yes, earwigs can reproduce at a moderate to rapid rate depending on food and environmental conditions. Females lay between 20 and 80 eggs and exhibit rare insect behavior by protecting their eggs until they hatch. A full life cycle takes several months, allowing for multiple generations per year.

10. What does an earwig look like?
Earwigs have a flat, elongated body, measuring 1.5–2.5 cm, with long antennae and prominent rear pincers. They have small, often hidden wings and range in color from dark brown to black. Though they may look aggressive, they are actually harmless.
11. Does finding an earwig at home mean the place is dirty?
Not necessarily. Their presence is more often linked to high humidity or hidden cracks that offer shelter—not poor hygiene. They may also be attracted to decaying organic materials or moisture leaks.
12. Do earwigs lay eggs in ears?
Absolutely not. This is one of the most horrifying and false myths about earwigs. They lay their eggs in safe, hidden places like soil or beneath leaves—not in the human body.
13. What’s the difference between male and female earwigs?
The primary difference lies in the shape of the rear pincers:
- Males have thick, curved pincers resembling the letter “C”
- Females have straighter, thinner pincers
This visual cue is a simple way to tell them apart.
14. Do earwigs harm plants?
They may cause minor damage to plants, especially by nibbling on young buds or ripe fruits, but they rarely pose a serious threat—especially when their population is not overwhelming.
15. Are earwigs beneficial in the garden?
Yes. They play a valuable ecological role by consuming harmful insects and decomposing matter, helping maintain a clean environment. In moderate numbers, their presence can be more helpful than harmful.
16. When are earwigs active?
Earwigs are nocturnal and are active from sunset to early morning. During the day, they hide in dark, damp areas to avoid light and heat.
17. Are earwigs attracted to light?
Yes, although not as strongly as flying insects like moths. They may be seen near lights at night, especially if they are searching for food or shelter.

18. Do earwigs live in all climates?
Earwigs can be found in most temperate and warm climates, particularly in humid environments. They do not thrive in extremely dry or cold regions, making them more common in moist areas.
19. How long do earwigs live?
An earwig’s lifespan ranges from 6 months to about a year, depending on species and environmental conditions. They tend to live longer in humid, temperate environments with sufficient food and shelter.
20. How can I prevent earwigs from entering my home?
Follow these tips to prevent infestation:
- Seal cracks and gaps around windows and doors
- Use dehumidifiers to reduce moisture
- Clean dark, damp corners regularly
- Install insect screens on windows and doors
- Keep food waste and organic matter covered
Conclusion:
At the end of this journey with the world of earwigs, we find ourselves in front of a small creature surrounded by many myths and misconceptions. Despite its appearance, which may seem disturbing, scientific truth reveals that it is a harmless insect, and sometimes even beneficial. There is no reason to panic about it entering the house, as it does not carry poison, nor does it attack humans, nor does it lay its eggs in their ears, as popular myths promote. By understanding its behavior, environment, and reproduction, we can coexist with it or control its presence in scientific and effective ways, without the need for exaggeration or unjustified anxiety, as earwigs represent a living example of how appearances can deceive us and popular stories can mislead us if we do not verify them scientifically. Therefore, let us make knowledge a tool to dispel ignorance and look at the world of insects with scientific eyes, appreciating it for its environmental role, without forgetting that we live in an interconnected ecosystem in which every creature has its place, even if it is small and frightening in appearance, like earwigs.
