We know you’re dealing with earwigs invading your space, potentially putting health and property at risk. If you need help identifying and eliminating the infestation at the source, connect with our recommended local professional near you.

Earwigs are fascinating insects that have captured the attention of many due to their distinctive appearance and their somewhat undeserved reputation. You might have come across these reddish-brown insects that measure about 5/8 inches long. A pair of strong pinchers at the tip of their abdomen is what sets them apart from other insects. But where do earwigs come from, and why do they sometimes appear unexpectedly in your home?

To answer this question, it’s essential to understand their natural habitat and habits. Earwigs are most active during the night, seeking refuge during the day by hiding in moist and dark spaces. They thrive in clusters, often found under wood, stone, mulch, compost, and debris piles. As opportunistic scavengers, they feed on soil organisms, fungi, algae, and other insects such as fleas and aphids, as well as snails.

Learning more about earwigs’ origins can help you understand their presence in specific environments and assist in controlling them, if necessary. Understanding their natural habitat and behavior is crucial to maintaining an earwig-free home or garden. So the next time you spot an earwig, remember that they come from the outdoors, where they play their role as nighttime scavengers.

Understanding Earwigs

Origins of Earwigs

Earwigs are intriguing insects belonging to the order Dermaptera. The name “earwig” comes from Old English, and despite its menacing reputation, these insects are not dangerous to humans. They have been around for quite some time, with over 2,000 species found worldwide.

Physical Features and Abilities of Earwigs

Earwigs are known for their unique physical features. They have flattened bodies, measuring about 5/8 inches in length, with reddish-brown coloring. They are equipped with medium-length antennae, short wings, and powerful pincers, also known as cerci or forceps, on the tip of their abdomen. The forceps of males are stout and curved, while females have straight-sided forceps.

These insects are surprisingly agile. They have two sets of wings: hindwings and forewings. Although their wings are short, earwigs can occasionally fly, demonstrating their adaptability.

Some characteristics of earwigs include:

• Curved cerci for males
• Straight-sided cerci for females
• Flat and reddish-brown body
• Short wings
• Medium-length antennae

Diet and Habitat of Earwigs

Earwigs can be found dwelling in various environments. They typically prefer places with mulch and organic debris on the ground. Their diet consists of both plant and animal matter. In some cases, they can be considered beneficial, as they consume pests, such as aphids, mites, and nematodes, along with algae, fungi, and decaying plants. However, they can also cause damage to some plants.

Here’s a comparison of their pros and cons:

Ultimately, earwigs are fascinating creatures with distinctive features, complex habitats, and diverse diets. Understanding their origins, characteristics, and behavior can help you appreciate these insects and properly manage them in your environment.

Life Cycle of Earwigs

Earwigs Reproduction

Earwigs mate during the late winter or early spring. The female lays 20 to 50 eggs in small chambers underground, under logs, or under stones. Interestingly, earwigs display maternal care, which is rare among insects. The mother stays with her eggs and guards them until they hatch, cleaning them to prevent fungal infections.

Earwigs Development

Earwigs undergo incomplete metamorphosis, which means they develop through a series of nymphal instars, with four to five stages before reaching adult form. As they grow, their coloration and body parts change slightly, but they mostly resemble adult earwigs throughout their development.

Some notable features of earwig development include:

• Eggs: Pearly-white or cream-colored, smooth, and oval in shape.
• Nymphs: Smaller and lighter-colored than adults, wingless, and with softer bodies.
• Adults: About 5/8 inch long, reddish-brown, flat body, with short wings and medium-length antennae.

Here’s a comparison of nymphs and adult earwigs:

In conclusion, understanding the life cycle of earwigs, including their reproduction and development, can help you better manage these insects and deal with them effectively.

Earwig Infestation

Signs of Earwig Infestation

Earwigs are typically harmless creatures, but their presence indoors can be annoying and unwanted. Some common signs of an earwig infestation include:

• Finding earwigs inside your home, particularly in damp areas like basements and bathrooms.
• Discovering damage to your plants, fruits, and flowers in your garden.
• Noticing small, irregular holes in leaves or petals, which are indicative of earwig feeding.

Where Are Earwigs Most Frequently Found

Earwigs are more active during the night and often dwell in dark, moist environments. They’re commonly found in:

• Outdoors: They thrive in gardens¹, mulch, and near fruit trees.
• Indoors: They may enter your home searching for shelter and can be found in basements², near windows, and under doors.

Preventing and treating earwig infestations

To prevent and get rid of earwigs in both indoor and outdoor spaces, consider the following tactics:

• Seal cracks and crevices around your home, especially near windows and doors.
• Keep your garden free of excessive leaf litter and mulch.
• Maintain proper moisture levels in your home to avoid creating a damp environment.
• Call a professional if the infestation grows where you can’t handle it

Myths About Earwigs

There are several myths surrounding earwigs that have contributed to their undeserved fear and infamy. One widespread belief is that earwigs crawl into people’s ears and burrow into their brain. This unsettling idea may have originated from the insect’s name, which is derived from an ancient superstition.

Rest assured, this myth has been debunked. While it’s true that earwigs can sometimes enter human ears, they do not have any interest in attacking your brain or causing you harm. In reality, they are more likely to be found in moist, dark environments like soil or under decaying wood.

Another misconception is that earwigs are dangerous and can cause harm with their pincers. In fact, their pincers, or cerci, are mainly used for defense against predators, as well as for mating purposes. They might give you a slight pinch if you pick one up, but they are generally considered harmless to humans.

Here’s a comparison table to summarize the common myths vs. reality:

To sum up, earwigs are simply misunderstood insects, and their fearsome appearance has led to many mistaken beliefs. Dispelling these myths helps us better understand and appreciate the role they play in nature.

Earwigs as Pests

Impact on Plants and Crops

Earwigs can cause damage to your garden, especially when they feed on the leaves, flowers, and fruits of various plants and vegetables. For example, they may create small holes on the leaf surface of young seedlings or chew around the edges of older leaves, giving them a ragged look ¹. You might also find earwigs on the ripening fruits of trees, such as peaches ².

Some common targets of earwigs include:

• Seedlings
• Young leaves
• Flowers
• Fruits (e.g., peaches and berries)
• Vegetables

Preventing and Controlling Earwig Infestation

To prevent and control earwig infestations in your garden, consider the following tips:

1. Remove hiding spots: Earwigs prefer moist, dark environments, so eliminate leaf piles, piles of vegetation, and damp areas near your plants and shrubs ³.
2. Install screens and lights: Adding screens to your windows and doors can keep earwigs out of your home. Swapping outdoor lights for yellow bulbs can also help, as they are less attractive to earwigs ⁴.
3. Use traps: Create simple traps using shallow containers filled with vegetable oil and a drop of honey, or by placing damp newspaper rolls or cardboard near the affected areas. Be sure to dispose of trapped earwigs daily ⁵.
4. Apply boric acid: Sprinkling boric acid around the perimeter of your house can act as a barrier to deter earwigs, but be cautious when using it near edible plants ⁶.
5. Vacuum: Regularly vacuum your home to eliminate any earwigs that might have gained access ⁷.
6. Consider calling a professional: they will help you with a plan to get rid of them.

However, it’s essential to keep in mind that earwigs can also be beneficial insects as they feed on other pests like aphids, mites, and nematodes ⁹. In some cases, their presence might be helpful in controlling other harmful pests in your garden.
