Key Points

• While generally harmless, earwigs can be a major nuisance in in homes.
• While there are some effective ways to prevent earwigs from proliferating and spreading, often, professional pest control is warranted.
• Understanding how earwigs behave and what attracts them to buildings is the first step to combatting them.

Despite their intimidating appearance and the persistent myth about them crawling into human ears, earwigs are actually more of a nuisance than a threat. However, when earwigs invade your home or garden in large numbers, they can become a serious problem requiring professional intervention. Although they only live for about a year at most, earwigs can reproduce several times—laying 50 to 90 eggs—during that span, meaning, left uncontrolled, an infestation can escalate quickly.¹

At Precision Pest & Wildlife Removal, we understand the frustration that comes with discovering these peculiar insects in your living spaces. Whether you are dealing with a minor infestation or a full-blown invasion, having some basic information about earwig behavior, prevention methods, and treatment options is essential for maintaining a pest-free environment. The guide we have put together below will tell you everything you need to know about these fascinating creatures and how to keep them out of your living spaces.

What Are Earwigs?

Earwigs belong to the order Dermaptera, which includes over 2,000 species worldwide.² These nocturnal insects are easily recognizable by their distinctive pincer-like appendages, called “cerci,” which extend from their abdomen. While their appearance might seem threatening, earwigs are generally harmless to humans and rarely cause significant damage to property.

Key Characteristics of Earwigs:

• Size: Most earwigs measure between 1/4 and 1 inch in length
• Color: Typically dark brown to reddish-brown 
• Body structure: Elongated, flattened body with prominent pincers
• Wings: Some species of earwigs have wings, though they rarely fly
• Habitat preferences: Dark, moist environments with adequate shelter

The most common species found in South Carolina is the European earwig (Forficula auricularia), which was introduced to North America in the early 1900s and has since become widespread across the continent. In 1853, South Carolina was the site of the first collection of the larger but less common seaside earwig (Anisolabis maritima).³

Common Problems Associated with Earwig Infestations

While earwigs do not pose serious health risks, they can create several problems for homeowners:

Indoor Invasions

• Contamination of food storage areas 
• Unsightly appearances in bathrooms and basements 
• Potential damage to houseplants 
• General discomfort and anxiety among residents

Garden and Landscape Damage

• Feeding on tender plant shoots and leaves 
• Damage to flower petals and vegetable crops 
• Consumption of beneficial insects 
• Creation of unsightly holes in ornamental plants

Structural Concerns

• Large populations can indicate moisture problems 
• Potential entry points may compromise home integrity 
• Associated pest attraction due to favorable conditions

Do Earwigs Bite Humans?

One of the most frequently asked questions about earwigs concerns their potential to bite humans. The truth about earwig bite incidents is more complex than simple yes or no answers:

• Earwigs possess mandibles capable of biting, but they rarely use them defensively against humans 
• Their pincers are primarily used for capturing prey and mating rituals 
• Most reported “bites” are actually pinches from their cerci 
• True bites are extremely rare and typically occur only when earwigs are handled roughly
• Any resulting irritation is minimal and comparable to minor insect bites

Like any insect, it is technically possible for earwigs to crawl inside a person’s ear. However, the myth about earwigs targeting human ears (and burrowing into brains!) is completely false and likely originated from their name and appearance rather than actual behavior.⁴

Understanding Earwig Behavior and Life Cycle

To effectively implement earwig control measures, it is crucial to understand their behavior patterns and reproductive cycle. Earwigs are primarily active during nighttime hours, spending their days hiding in dark, damp locations such as:

• Under rocks, logs, and mulch
• In garden debris and compost piles
• Behind loose bark on trees 
• In cracks and crevices around foundations 
• Under outdoor furniture and planters

The Earwig Life Cycle

Earwig larvae development follows a simple metamorphosis process consisting of three main stages:

• Egg stage: Female earwigs lay an average of 50 eggs in underground burrows during late fall or early winter 
• Nymphal stage: Young earwigs emerge in spring, resembling miniature adults but lacking fully developed reproductive organs 
• Adult stage: After several molts over four to six weeks, nymphs reach sexual maturity⁵

Understanding this cycle is essential for timing earwig removal efforts effectively, as targeting reproduction periods can significantly reduce future populations.

Prevention Strategies for Earwig Control

Effective earwig management begins with prevention. By addressing the environmental factors that attract these insects, homeowners can significantly reduce the likelihood of infestations.

Moisture Management

Eliminating sources of water is a good way to discourage the presence of many different insects, including earwigs. 

• Repair leaking pipes and faucets promptly 
• Ensure proper drainage around foundations 
• Use dehumidifiers in basements and crawl spaces 
• Fix damaged gutters and downspouts 
• Remove standing water from outdoor containers

Habitat Modification

Eliminating environments that are conducive to earwigs is another effective strategy. 

• Remove garden debris, fallen leaves, and organic matter regularly 
• Trim vegetation away from building foundations 
• Store firewood and lumber away from structures 
• Eliminate hiding spots such as rock piles and unused equipment 
• Maintain proper ventilation in storage areas

Exclusion Methods

A final prevention approach involves barriers to earwig infiltration.

• Seal cracks and gaps around doors, windows, and foundations 
• Install door sweeps and weather stripping 
• Repair damaged screens and vents 
• Apply caulk to potential entry points 
• Consider perimeter treatments around building exteriors

Natural Earwig Repellent and Trap Options

For environmentally conscious homeowners, several natural earwig repellent methods can provide effective control without harsh chemicals:

Diatomaceous Earth Applications

• Food-grade diatomaceous earth creates barriers that damage earwig exoskeletons⁶
• Apply thin layers around potential entry points and hiding spots 
• Reapply after rain or irrigation 
• Ensure proper protective equipment when handling

Earwig Traps

• Effective earwig traps serve dual purposes: population reduction and monitoring infestation levels. 

• DIY traps can be made with a roll of damp newspapers secured with rubber bands
• Another option is a combination of vegetable oil and soy sauce placed  in shallow containers 
• Place in areas with high earwig activity 
• Check and dispose of trapped insects daily 
• Replace newspapers regularly for continued effectiveness

Essential Oil Treatments

• Peppermint, eucalyptus, and citrus oils repel earwigs naturally 
• Mix with water and spray around affected areas 
• Refresh applications weekly for optimal effectiveness 
• Combine multiple oils for enhanced repellent properties

Beneficial Predator Encouragement

• Attract birds, spiders, and ground beetles that prey on earwigs 
• Maintain diverse garden ecosystems 
• Provide nesting sites for beneficial species 
• Avoid broad-spectrum pesticides that harm natural predators
