Understanding Earwig Infestations in Garden Environments

Signs That You Have an Earwig Problem

Look for jagged holes in young plant leaves and flowers, especially on dahlias, zinnias, and lettuce. You’ll often find earwigs hiding in dark, moist areas like mulch, under pots, or in garden debris during daylight hours. Their presence becomes more noticeable at night when they emerge to feed, and you might spot their distinctive pincer-like forceps when disturbing their hiding spots.

Why Earwigs Can Damage Your Garden

Earwigs primarily attack tender new growth, seedlings, and soft fruits like strawberries and raspberries. They create unsightly damage by chewing irregular holes in leaves and flowers, which can stunt plant development or kill young seedlings entirely. While they do consume some garden pests like aphids, their plant-damaging habits often outweigh this benefit, especially during population explosions in warm, humid conditions.

Rolled Newspaper Traps: The Classic DIY Solution

Rolled newspaper traps offer a simple, non-toxic approach to controlling earwigs in your garden without using harmful chemicals. This traditional method leverages earwigs’ natural attraction to dark, moist environments.

How to Make and Place Newspaper Traps

1. Preparation: Thoroughly wet a newspaper and roll it into a tight tube, creating an irresistible dark, moist hideaway for earwigs.
2. Placement: Position your wet newspaper rolls near vulnerable plants, along fences, or in shady areas just before sunset when earwigs become active.
3. Collection: In the morning, carefully unroll each newspaper over a bucket of soapy water, allowing trapped earwigs to fall in and drown.

Best Practices for Maximum Effectiveness

1. Strategic timing: Set traps in late afternoon or early evening since earwigs are nocturnal and seek shelter during nighttime hours.
2. Target high-activity zones: Place traps near seedlings, flowers, and in moist, shaded areas where earwigs commonly congregate and cause damage.
3. Maintain consistency: Replace traps daily until you notice a significant decrease in captured earwigs, ensuring continuous population reduction.
4. Proper disposal: Drown captured earwigs in soapy water or crush them in sealed plastic bags to prevent escape and reinfestation.

Oil Pit Traps: Simple Yet Highly Effective

Oil pit traps are among the most efficient and cost-effective solutions for controlling earwig populations in your garden. These traps exploit earwigs’ natural behavior patterns and can be created using common household items.

Setting Up the Perfect Oil Trap

To create an effective oil pit trap:

1. Choose the right container – Use shallow containers like tuna cans, cat food cans, or small plastic bowls that can hold ½-1 inch of oil.
2. Prepare entry points – For plastic containers, poke pencil-sized holes in the lid to allow earwigs entry. Cans can be left open at the top.
3. Install properly – Bury the trap so the top is level with the soil surface, making it easy for earwigs to discover and enter.
4. Position strategically – Place traps near shrubbery, ground cover, or alongside fences where earwigs typically hide.

Recommended Oils for Better Results

Different oil combinations attract earwigs with varying degrees of success:

• Fish oil – Tuna fish oil provides exceptional attraction power for earwigs.
• Vegetable oil with bacon grease – Adding a drop of bacon grease to vegetable oil creates an irresistible lure.
• Soy sauce mixture – Combining soy sauce with used vegetable oil (more effective than fresh oil) yields excellent results.
• Linseed oil – Particularly effective though requires more frequent replacement as it tends to dry out.

Remember to check your traps daily, dispose of captured earwigs, and refresh the oil regularly to maintain effectiveness throughout the growing season.

Commercial Sticky Traps: Ready-to-Use Options

Sticky traps offer an effective, pesticide-free solution for capturing earwigs in your garden without the hassle of DIY methods. These commercially available options provide consistent results with minimal setup time.

Top Brands for Sticky Earwig Control

When selecting sticky traps for earwigs, focus on products designed specifically for small insects. Look for pesticide-free options like Enoz Trap-N-Kill Earwig Traps, which mimic earwigs’ preferred hiding spots. These ready-made solutions are safe around pets and children but should be positioned out of reach to prevent accidental contact.

Strategic Placement for Optimal Capture

For indoor infestations, position traps in bathrooms, basements, and cabinets where earwig activity is high. In gardens, place traps near vulnerable plants, alongside fences, and under ground cover where earwigs congregate. Adding attractants like peanut butter, fish oil, or fruit to your traps can significantly increase capture rates during peak activity periods.

Diatomaceous Earth Barriers: Natural Preventative Measure

Diatomaceous Earth (DE) offers a powerful, organic solution for controlling earwigs without harmful chemicals. This naturally occurring sedimentary rock, when crushed into a fine powder, becomes an effective barrier against these persistent garden pests.

Application Techniques for Garden Protection

Create a protective barrier by sprinkling a thin, continuous line of DE around vulnerable plants, garden beds, and foundations. Apply the powder directly to soil surfaces, focusing on areas where earwigs travel or congregate. For maximum effectiveness, create a band 1-2 inches wide and ¼ inch thick, ensuring complete coverage without gaps. Reapply after disturbances to maintain the protective perimeter.

Weather Considerations When Using DE

Diatomaceous Earth loses effectiveness when wet, making timing crucial for successful application. Apply during dry periods when no rain is forecasted for at least 48 hours. After rainfall or irrigation, reapplication is necessary to restore the protective barrier. Store unused DE in airtight containers to prevent moisture absorption, and consider using protective covers in high-value areas during brief rain events to preserve treatment efficacy.

Plant-Based Attractant Traps: Eco-Friendly Alternatives

When you’re looking for chemical-free solutions to control earwigs, plant-based attractant traps offer effective and environmentally friendly options. These natural methods leverage earwigs’ feeding preferences and behaviors without introducing harmful substances into your garden ecosystem.

Oil and Soy Sauce Traps

Oil and soy sauce traps are remarkably effective at attracting and capturing earwigs. Simply fill a small plastic container halfway with a mixture of vegetable oil and soy sauce. Create pencil-sized holes in the lid and bury the container in your garden soil so the lid sits at ground level. Earwigs are strongly attracted to the soy sauce scent and will crawl through the holes, fall into the oil, and drown. This method is non-toxic, inexpensive, and can be placed throughout your garden near vulnerable plants.

Linseed Oil Traps

Linseed oil serves as another powerful natural attractant for earwigs. Place containers filled with linseed oil in earwig hotspots throughout your garden. This plant-based oil proves particularly effective at luring these pests, though you’ll need to monitor it as it may dry out over time. As an added eco-friendly benefit, once the trap has served its purpose, you can reuse the oil-and-earwig mixture in your compost pile or as protein-rich chicken feed, creating a zero-waste pest management solution.

Vegetables and Herbs That Attract Earwigs

Earwigs target specific plants in your garden that you can use to your advantage when setting traps. They’re particularly drawn to tender seedlings, lettuce, and corn silk. Strawberries, raspberries, blackberries, and stone fruits like peaches also attract them. Flowering plants such as dahlias, hollyhocks, marigolds, and zinnias are frequent targets, making these areas prime locations for trap placement.

Creating a Combination Bait and Trap System

Combine different trap styles with effective baits for maximum earwig control. Pair newspaper traps (rolled, dampened newspaper) with nearby oil traps containing soy sauce attractant. Deploy container traps with vegetable oil and a drop of soy sauce buried at soil level near vulnerable plants. For best results, place these combined systems at sunset when earwigs become active, and check them early morning for disposal.

Maintaining a Long-Term Earwig Control Strategy

Taking control of earwig populations in your garden doesn’t require harsh chemicals or expensive solutions. The six trap methods outlined give you flexible options that fit your gardening philosophy and budget. Whether you prefer DIY newspaper rolls or ready-to-use sticky traps, consistency is key to success.

Remember that earwigs can be beneficial in small numbers by controlling other pests. Your goal should be management rather than complete elimination. By strategically placing traps near vulnerable plants and checking them regularly, you’ll maintain the delicate balance needed for a thriving garden ecosystem.

Combine different trapping methods throughout the season for best results, especially during warm humid periods when earwig activity peaks. With these simple yet effective solutions, you’ll enjoy healthier plants and fewer damaged seedlings all season long.

Frequently Asked Questions

What damage do earwigs cause to garden plants?

Earwigs primarily damage young seedlings and plants by creating jagged holes in leaves and flowers. They target tender new growth and soft fruits, particularly on dahlias, zinnias, and lettuce. This damage can stunt plant development or even kill seedlings. While earwigs also help control other pests, their destructive impact often outweighs these benefits when populations surge during warm, humid conditions.

How can I identify an earwig infestation in my garden?

Look for jagged, irregular holes in young plant leaves and flowers, especially on dahlias, zinnias, and lettuce. Earwigs hide in dark, moist areas during daylight hours and become more active at night. If you notice damaged tender growth and soft fruits with no visible pests during the day, check your garden after sunset with a flashlight to confirm earwig activity.

How do you make a newspaper trap for earwigs?

Roll several sheets of newspaper into tubes, secure with string or rubber bands, and dampen them. Place these rolls near vulnerable plants in the evening. Earwigs will seek shelter in the dark, moist environment overnight. In the morning, collect the traps and shake the captured earwigs into a bucket of soapy water.
