Earwigs, those peculiar-looking insects with menacing pincers on their hind ends, are not just garden-dwelling creatures but can also find their way into households. Identifying and eliminating earwigs is not just about overcoming the shudder-inducing effect they have on most people. These nocturnal insects are known for their voracious appetites, capable of causing significant damage to plants and crops. Additionally, their presence in homes can be annoying, with a tendency to invade dark, damp spaces.

Now, let’s delve into the details.

What are Earwigs?

Earwigs belong to the order Dermaptera, and despite their intimidating appearance, they are not harmful to humans. These insects typically have elongated bodies, pincer-like appendages (cerci) at the end of their abdomen, and membranous wings folded underneath short forewings.

How to Identify Earwigs?

Body Shape: Earwigs have elongated, flattened bodies, typically ranging from 5 to 25 mm (0.2 to 1 inch) in length, depending on the species.

  • Color: They are usually dark brown to black, though some species may have reddish or yellowish hues.
  • Pincers (Cerci): One of the most distinctive features of earwigs is their pincers, called cerci, located at the end of their abdomen. These cerci are curved and resemble forceps.
  • Wings: Adult earwigs have wings, but not all species can fly. Their hind wings are membranous and fold underneath short, leathery forewings, creating a distinctive shape.
  • Antennae: Earwigs have fairly long antennae that can be segmented. These antennae are often as long as or longer than the body.
  • Habitat: Earwigs are nocturnal insects that prefer damp, dark environments. You may find them under rocks, logs, mulch, or in other moist areas around your home and garden.
  • Behavior: Earwigs are known for their nocturnal activity and are often found feeding on decaying plant material, other insects, and occasionally on living plants. They are also attracted to lights at night.
  • Eggs: Earwig eggs are typically white and elongated, often found in clusters.

What do Earwigs Eat?

Earwigs are omnivores, feeding on a variety of organic matter, insects, and plants. While they can be beneficial by preying on garden pests, they may also consume plant material, posing a threat to ornamental and vegetable plants.

How to Get Rid of Earwigs?

To control and get rid of earwigs, you can employ a combination of preventive measures and targeted treatments.

  • Remove Hiding Places: Earwigs seek shelter in dark and damp areas. Reduce their hiding spots by eliminating debris, mulch, and unnecessary vegetation around your garden or home.
  • Regular Cleaning: Keep your garden and outdoor spaces clean. Regularly remove decaying plant matter, organic debris, and any potential hiding spots for earwigs.
  • Moisture Control: Since earwigs thrive in damp environments, ensure proper drainage in your garden. Fix leaks, avoid overwatering, and promote good air circulation to reduce excess moisture.
  • Traps and Barriers: Set up traps, such as rolled-up newspapers or cardboard tubes, in areas where earwigs are active.
  • Natural Predators: Encourage natural predators of earwigs, such as birds and beneficial insects like ground beetles and parasitic wasps, which feed on earwigs.
  • Diatomaceous Earth: Sprinkle food-grade diatomaceous earth around plants and areas where earwigs are present. This natural substance, composed of fossilized diatoms, has abrasive particles that can damage the earwig’s exoskeleton.
  • Essential Oils: Use essential oils like neem oil, peppermint oil, or citrus oil, diluted in water, as a natural spray to repel earwigs. Spray it on plants and areas where earwigs are active.
  • Insecticides: If the infestation is severe, consider using insecticides labeled for earwig control. Follow the instructions carefully and choose products that are safe for plants and the environment.

How does Earwigs Spread?

Earwigs can spread through various means, primarily through natural behaviors and environmental conditions. Here are some ways earwigs can spread:

  • Natural Movement: Earwigs are mobile insects and can move from one place to another on their own.
  • Hitchhiking: Earwigs can inadvertently get transported to new locations by attaching themselves to objects or materials. This can include plants, outdoor furniture, firewood, or any other items where they find shelter.
  • Egg Transfer: Female earwigs lay their eggs in protected locations. If these eggs or young nymphs are attached to objects, they can be unintentionally transported to new areas.
  • Flight: While not all species of earwigs are capable of flight, some adult earwigs do have wings and can fly short distances.

What Causes Earwigs?

Earwigs are attracted to specific environmental conditions and habitats. Several factors contribute to the presence of earwigs, and understanding these factors can help you address and prevent infestations.

  • Moisture: Earwigs thrive in damp and humid environments. Excess moisture around the home, such as leaky faucets, standing water, or poor drainage, can attract earwigs.
  • Organic Debris: Earwigs feed on decaying plant material and are often found in areas with organic debris like leaf litter, mulch, or compost piles.
  • Outdoor Lighting: Outdoor lighting can draw them towards homes and other structures. Consider using less attractive or yellow-colored outdoor bulbs to minimize this attraction.
  • Vegetation and Gardens: Earwigs feed on a variety of plants, fungi, and insects. Gardens and lush vegetation can provide a food source and habitat for earwigs.
  • Cracks and Crevices: Earwigs often seek shelter in cracks, crevices, and other dark hiding spots during the day.
  • Warm Temperatures: During the summer months, their populations may increase. Implementing preventive measures during warmer seasons can be particularly effective.

What is the Purpose of Earwigs?

Earwigs play several ecological roles in their natural habitats, and they have both beneficial and detrimental aspects.

  • Decomposers: Earwigs feed on decaying plant material, fungi, and small insects. As scavengers, they help break down and recycle organic matter in their environment, contributing to the decomposition process.
  • Insect Predators: While earwigs primarily feed on decomposing plant material, they also consume small insects, insect eggs, and aphids. In this way, they can be considered beneficial in controlling certain insect pests in gardens and agricultural settings.
  • Food Source for Predators: Earwigs serve as a food source for various predators, including birds, spiders, frogs, and other insects. They contribute to the overall balance of ecosystems by participating in food chains.
  • Soil Aeration: As earwigs burrow into the soil, they contribute to soil aeration. Their activities help in loosening and turning the soil, which can be beneficial for plant roots and other soil-dwelling organisms.

While earwigs have these positive ecological roles, they can also be considered pests when their populations become excessive, especially in and around human structures. In such cases, they may damage plants, ornamental flowers, and some crops, and their presence in homes can be undesirable.

How to Prevent Earwigs?

Preventing earwigs involves creating an environment that is less attractive to these insects and implementing measures to deter their entry into your living spaces.

  • Reduce Moisture: Address any leaks or standing water around your home. Improve drainage to prevent water accumulation near the foundation. Ensure proper ventilation in basements and crawl spaces.
  • Remove Organic Debris: Clean up leaf litter, mulch, and other organic debris around your home. Regularly rake and dispose of fallen leaves in the yard.
  • Trim Vegetation: keep plants, shrubs, and trees well-trimmed to reduce hiding places for earwigs. Maintain a gap between the vegetation and the exterior of your home.
  • Create a Dry Zone: Use gravel or rock mulch around the foundation to create a dry zone, making it less attractive to earwigs.
  • Seal Entry Points: Inspect and seal cracks, gaps, and entry points around doors, windows, and the foundation. Repair or replace damaged window screens.
  • Outdoor Lighting: Use less attractive or yellow-colored outdoor lights, as bright lights can attract earwigs at night.
  • Clean Gutters: Regularly clean gutters to prevent clogs and standing water.
  • Raise Garden Beds: If you have raised garden beds, consider elevating them to reduce moisture and make them less appealing to earwigs.
  • Use Beneficial Insects: Attract or introduce natural predators of earwigs, such as birds, frogs, and predatory insects.
  • Natural Repellents: Consider using natural repellents, such as diatomaceous earth or neem oil, around plants or areas where earwigs are active.
  • Regular Inspections: Conduct regular inspections of your home and garden to identify and address potential issues before they escalate.
