Potential Harm To Humans And Pets

Contrary to their menacing appearance, earwigs are generally harmless to humans and pets. While they possess pincers, they rarely use them for defense against larger creatures. Earwigs do not sting or transmit diseases to humans or animals. However, in rare cases, they may pinch if handled or threatened, resulting in minor discomfort similar to a mosquito bite.

The primary concern with earwigs is the damage they can inflict on plants and crops in gardens. Their omnivorous diet includes tender shoots, leaves, and the occasional fruits, which can be problematic for gardeners. While they may nibble on plants, they are not considered a major agricultural pest.

Signs Of An Earwig Infestation

Detecting the presence of an earwig infestation is pivotal in implementing effective prevention strategies. Several telltale signs can help you identify whether these insects have made their way into your living spaces or garden.

First and foremost, keep an eye out for sightings of earwigs inside your home. These nocturnal creatures tend to emerge at night and can often be found in bathrooms, kitchens, basements, or any areas where moisture levels are higher. Their presence indoors is a clear indicator that prevention measures may be needed.

In outdoor spaces like gardens and yards, look for evidence of earwig activity. This may manifest as irregular holes or chewed edges on leaves, flowers, or vegetables. Earwigs are known for their omnivorous appetite and can cause damage to various plants and crops.

Additionally, inspect sheltered areas around your home for signs of earwigs. These insects prefer hiding in dark, damp spaces, making cracks in walls, gaps around doors and windows, and locations with decaying organic matter prime spots for infestation.

Another subtle clue to watch for is the shed exoskeletons of earwigs. As they grow, earwigs molt, leaving behind tiny, translucent shells that can accumulate in areas where they are active. Pay attention to any small, dark droppings resembling black pepper grains. Earwigs leave these fecal droppings in the areas they frequent, providing further evidence of their presence.

Reasons for Earwig Infestation

Earwigs are known for their ability to infiltrate homes, and understanding why they’re drawn to residential spaces is crucial in preventing infestations. Let’s explore the factors that attract earwigs to homes and how these resilient insects find their way indoors.

Factors That Attract Earwigs To Homes

Earwigs are highly attracted to moisture-rich environments. Leaky pipes, damp basements, and areas with poor ventilation can create the ideal conditions for earwigs to thrive. Ensuring your home is dry and well-ventilated is a key step in deterring them.

Earwigs are nocturnal creatures, and outdoor lighting can be a significant attraction. Light sources near windows or doors can draw them towards your home. Consider using less attractive, yellow or sodium vapor lights instead of bright white lights.

Dense vegetation around your home can serve as a habitat and a food source for earwigs. Overgrown shrubs, mulch beds, and piles of decaying plant matter create hiding spots and encourage infestations. Regularly trim vegetation and maintain your garden to reduce these attractions.

Earwigs are scavengers and feed on decaying organic matter. If you have compost piles or heaps of leaves near your home, they can become breeding grounds. Keep compost bins sealed and maintain yard cleanliness.

Earwigs are excellent at squeezing through tiny openings. Gaps in doors, windows, siding, or foundations provide easy entry points. Seal these cracks with weatherstripping, caulk, or other suitable materials to prevent access.

How Do Earwigs Enter Homes?

Earwigs, with their remarkable adaptability, can find their way into homes through various means. Understanding these entry points is vital for crafting effective prevention strategies.

One common entry pathway is through open doors and windows. Earwigs are predominantly nocturnal, and they may take advantage of open portals, especially during the evening hours when they are most active. To mitigate this, consider installing screens on doors and windows and keeping them closed when earwig activity is expected.

Cracks and crevices in a home’s exterior provide another avenue for earwigs to infiltrate. These insects are skilled at navigating through tiny openings, and they can slip through gaps in door frames, window sills, or any imperfections in the structure. Regular inspections of your home for potential entry points are essential. Seal any openings you find with weatherstripping, caulk, or other appropriate materials to block access.

Vents and pipes also present opportunities for earwigs to enter homes. Inadequately screened vents can be a gateway for these pests, as can gaps around plumbing pipes. Installing mesh screens over vents and inspecting and sealing gaps around pipes can effectively prevent earwig intrusion.

Additionally, earwigs might inadvertently find their way indoors by hitchhiking on items brought in from the outside. Firewood, potted plants, outdoor furniture, and other objects can harbor these insects. Before bringing such items indoors, it’s prudent to inspect them for any lurking earwigs and remove them.

Natural Remedies and Prevention

When it comes to keeping earwigs at bay, many homeowners prefer natural and eco-friendly methods. This section explores various natural remedies and preventive measures that can help you maintain a pest-free home and garden.

Essential oils like lavender, mint, and citrus are known for their pleasant fragrances, but they also have repellent properties that can deter earwigs. Mix a few drops of these oils with water and spray them around entry points and problem areas in your home.

This natural, abrasive powder is harmless to humans and pets but can be deadly to earwigs. Sprinkle diatomaceous earth around the perimeter of your home and in areas where earwigs are active. It damages their exoskeleton and dehydrates them. Neem oil is another effective natural remedy. It not only repels earwigs but also disrupts their life cycle. Dilute neem oil with water and use it as a spray in infested areas.

DIY Traps and Barriers for Prevention

In the quest to prevent earwig infestations, do-it-yourself (DIY) traps and barriers can be valuable tools. These techniques offer effective and environmentally friendly solutions for keeping earwigs at bay.

Oil Traps

Crafting oil traps is a straightforward yet highly effective method. Simply place shallow containers filled with vegetable oil or soy sauce in areas where earwigs are often spotted. These pests are lured in by the scent but meet an untimely end as they drown upon contact with the liquid. It’s an ingenious way to reduce their numbers indoors.


Creating physical barriers that discourage earwigs from entering your home is another approach. For instance, copper tape or a smear of petroleum jelly applied around potential entry points can deter these insects. The slick surface of the jelly makes it difficult for earwigs to crawl across, while copper tape emits a mild electric shock when they touch it. Both methods serve as formidable deterrents.

Specific Plants in Deterring Earwigs

In the pursuit of natural and ecologically friendly ways to deter earwigs, consider the strategic use of certain plants that have demonstrated the ability to repel these insects. By incorporating these plants into your garden or near potential entry points to your home, you can create a natural defense against earwig infestations.


Marigolds, known for their vibrant blooms, also have a distinct fragrance that is unappealing to earwigs. Planting marigolds in your garden can act as a natural deterrent, discouraging these insects from feasting on your plants.

Basil and Mint

Aromatic herbs like basil and mint can be effective in keeping earwigs at bay. Their strong scents and textures make them less inviting to these pests. By strategically planting basil and mint in your garden, you not only add culinary delights but also create a natural barrier against earwigs.
