So you’re wondering how to get rid of earwigs naturally, and you want a plan that actually works without spraying poison around your home or garden. That’s exactly what this guide is for. Earwigs (Forficula auricularia) are mostly a nuisance, but they can damage seedlings, soft fruit, and even crawl indoors at night if conditions are right.

The good news? You don’t need harsh chemicals to send them packing.

Our research shows that a smart natural approach comes down to three things: cutting the moisture they depend on, removing the hiding spots they love, and using simple traps to catch the ones that stick around. It’s a process, not a one‑and‑done spray. But once you understand how earwigs operate, you can outsmart them for good.

Let’s walk through exactly how.

Quick Answer

Mix one part soy sauce with one part vegetable oil in a shallow dish. Place it where you’ve seen earwigs. They crawl in and drown overnight.

Empty the trap each morning. Outdoors, create a dry barrier of food‑grade diatomaceous earth or crushed stone around your foundation. Indoors, seal cracks and run a dehumidifier.

Keep leaf litter and mulch at least a foot away from walls. That’s the natural method in a nutshell.

Is Natural Earwig Control Actually Going to Work?

Short answer: yes, if you’re willing to be persistent. Natural control doesn’t kill earwigs instantly like a synthetic chemical would. Instead, it reduces the population over one to two weeks by targeting their environment and behaviour.

The key is to treat the source, not just the symptoms.

Earwigs are nocturnal scavengers. They hide in damp, dark places during the day, under mulch, inside woodpiles, behind plant pots, along foundation cracks. At night they come out to feed on decaying plant matter, soft fruit, and sometimes young garden plants.

Moisture is their lifeline. If you take that away, they either leave or die.

Natural control works because it disrupts this cycle. You remove the damp hiding spots. You block their travel routes.

You trap the ones that are already active. As of 2026, numerous university extension programmes (including several land‑grant .edu sources) confirm that integrated pest management with these methods is effective for home gardeners. Manufacturer specifications for food‑grade diatomaceous earth indicate it remains effective as long as it stays dry, which is why keeping it in place matters.

The honest truth? If you have a heavy infestation (hundreds of earwigs), natural methods will take longer and you’ll need to be diligent. But for the vast majority of home situations, a few dozen earwigs in the basement or some nibbled lettuce in the garden, natural control works fine.

No need to bring out the big guns.

First, Figure Out Where They’re Coming From

Before you start any treatment, you need to answer one question: are you dealing with an indoor problem, an outdoor problem, or both? This decides every step that follows.

Signs of an indoor infestation

• You find earwigs in bathrooms, basements, or kitchens, especially at night.
• They show up near plumbing leaks, under sinks, or around washing machines.
• You see them near exterior door thresholds or windowsills.
• Not so many that you can’t walk without stepping on them, but enough to bother you.

Indoor earwigs almost always have a moisture source. A slow drip under the sink, a damp crawlspace, a leaky pipe, fix that and the earwigs lose their reason to stay inside.

Signs of an outdoor infestation

• Earwigs are damaging your vegetable garden (especially lettuce, strawberries, and seedlings).
• You find them under flower pots, inside mulch, or hiding in dense ground covers.
• Large numbers are visible on the outside of your home at night when you step out with a flashlight.
• You have heavy leaf litter, woodpiles, or rock piles near the foundation.

Outdoor populations are normal, a few earwigs aren’t a problem. But when they’re large enough to invade the house or damage your plants, you need to act.

The quick check

Take a flashlight at dusk. Walk around your home’s foundation, garden beds, and any wood or debris piles. Count how many earwigs you see in five minutes.

More than a dozen? You’ve got a real population. Zero to five?

Just a few stragglers, no need to panic.

This step takes fifteen minutes and saves you from trying random fixes that don’t match the situation.

Quick Decision Branch: Indoor, Outdoor, or Both?

Now that you know where they are, choose your path.

Indoor‑only means the earwigs are likely coming in from outside through cracks or gaps. Your first job is to stop that migration. Outdoor‑only means you can focus on garden management without worrying about them getting inside.

If you have both, always start outdoors. The earwigs that appear indoors are the ones that walked in from a nearby outdoor breeding ground. Clear the source, and the indoor problem dries up naturally.

If They’re Already Inside: Stop the Invasion First

Alright, you’ve got earwigs in the living space. Let’s get rid of them without spraying chemicals indoors.

Step 1: Find and seal their entry points

Earwigs are small. They can squeeze through cracks as thin as a credit card (about 1/16 inch). Check:

• Gaps under exterior doors (install weatherstripping or a door sweep).
• Cracks in the foundation, caulk these with exterior silicone.
• Spaces around window frames, pipe entry points, and utility lines.
• Gaps around baseboards inside your home, especially in basements.

Sealing these stops the nightly migration. It won’t kill the earwigs already inside, but it prevents new ones from joining them.

Step 2: Dry out the area they’re hiding in

Earwigs need moisture. Use a dehumidifier in basements or damp bathrooms. Fix any plumbing leaks.

Improve ventilation in crawlspaces. Our research shows that reducing indoor humidity below 50% makes an area much less attractive to earwigs. They’ll either leave or dry out.

Step 3: Set the right traps inside

The most effective indoor trap for earwigs is a shallow dish (like a tuna can or takeout container) filled with a mixture of equal parts soy sauce and vegetable oil. Place it along baseboards, behind appliances, or near any cracks where you’ve seen them. The soy sauce attracts them, the oil traps them, and they drown overnight.

Empty the trap each morning and replace the liquid.

Alternatively, you can use a shallow pan with a few drops of cooking oil in water. The oil creates a film that traps them. But the soy sauce version works better because it lures them from across the room.

What about sticky traps?

Sticky traps (the flat cardboard sheets with adhesive) can catch earwigs, but they’re better for monitoring than full control. They fill up quickly and only catch the ones that happen to walk across them. Use a few along baseboards to gauge activity, but rely on the liquid trap to actually reduce numbers.

If They’re in the Garden: Protect Your Plants Without Chemicals

When earwigs are eating your lettuce or marigolds, you need to act fast. Seedlings are most vulnerable. A single earwig can chew through a young stem in one night.

Step 1: Confirm it’s earwigs (and not slugs or caterpillars)

Earwig damage looks like small irregular holes in leaves, often with a ragged edge. Slugs leave slime trails and large ragged holes. Caterpillars leave round holes and visible droppings.

The easiest test: go out at night with a flashlight. If you see earwigs on the plant, that’s your culprit.

Step 2: Create a dry barrier they won’t cross

Earwigs hate crossing dry, abrasive surfaces. This is where food‑grade diatomaceous earth shines. Sprinkle a thin line (about 1/2 inch wide) around the base of each plant or along the edge of your garden beds.

Reapply after rain. Do not use pool‑grade diatomaceous earth, it’s chemically treated and dangerous to inhale.

Another trick: Place a strip of crushed stone or coarse sand about 1 to 2 inches wide around your raised beds. Earwigs avoid crawling over it because it’s uncomfortable and dry.

Step 3: Use rolled‑up newspaper traps

Roll a newspaper into a cylinder, secure it with a rubber band, and dampen it slightly. Place it on the soil near affected plants in the evening. Earwigs will crawl inside to hide during the day.

In the morning, pick up the newspaper and shake the earwigs into a bucket of soapy water. Repeat daily for a week.

Step 4: Remove hiding spots near your garden

Pull back mulch so it’s no more than 2 to 3 inches deep. Keep leaf litter and grass clippings away from the base of plants. Store woodpiles and compost bins at least 15 feet from your garden beds.

Earwigs breed in damp organic matter, the less you have near your plants, the fewer earwigs you’ll see.

Step 5: Encourage natural predators

Birds, toads, and centipedes all eat earwigs. A birdbath or a small frog habitat can help, but the biggest impact comes from maintaining a diverse garden that attracts these predators naturally.

If You Just Want to Keep Them Away: Prevention-First Approach

Prevention is the easiest natural method, because you stop earwigs before they become a problem. Focus on three things: moisture control, habitat removal, and physical barriers.

Start with moisture. Earwigs need damp places to survive. Fix leaky outdoor spigots, downspouts that drain near the foundation, and any standing water in your yard.

If you have a crawlspace, make sure it’s properly ventilated and dry. A dehumidifier in a damp basement can make a huge difference.

Next, remove their hiding spots. Earwigs love thick mulch, leaf litter, and dense ground covers. Keep mulch layers no deeper than 2 to 3 inches.

Rake up fallen leaves regularly. If you have woodpiles, stack them off the ground and away from your house. The same goes for compost bins, keep them at least 15 feet from your foundation.

Consider replacing organic mulch with inorganic options like rubber mulch or crushed stone near your home’s perimeter. That eliminates the damp, dark environment earwigs crave. You can also use a 1‑foot wide strip of coarse gravel as a dry moat around your foundation.

For more on choosing the right material, check out our guide on best gravel for patio area.

Encourage natural predators. Birds, toads, and centipedes all eat earwigs. A simple birdbath or a small pond can attract insect‑eating birds.

Planting a diverse mix of flowers also invites beneficial insects that compete with earwigs. For ideas on what to plant, see our recommendations for best flowers for flower beds.

The Traps That Actually Work (and the Ones That Don’t)

Not all traps are created equal. Some catch dozens per night. Others are a waste of time and soy sauce.

Here’s what works and what doesn’t.

The top‑performing traps

The soy sauce and vegetable oil trap is the undisputed champion for indoor use. The ratio should be one part soy sauce to one part oil. Place it in a shallow dish (like a tuna can) flush with the floor.

Earwigs crawl in, the oil coats them, and they can’t get out. Empty it every morning.

Traps to skip

• Beer traps. These are popular for slugs, but earwigs aren’t attracted to fermented yeasts. You’ll catch more slugs than earwigs.
• Fruit bowls. Some people swear by leaving a piece of rotting fruit in a container. In our research, this attracts flies and ants faster than earwigs. Not worth the mess.
• Simple water traps with no attractant. A dish of water alone catches almost nothing. Earwigs don’t seek out water; they want moist hiding spots.

If you want a trap that doubles as a quick fix, a damp rolled‑up newspaper is free and works well in the garden. Collect and dispose of the paper each morning. It’s simple but effective.

Common Mistakes That Sabotage Your Efforts

Even the best natural methods fail if you make these errors. Avoid them and you’ll see results much faster.

Mistake 1: Using diatomaceous earth in wet conditions

Food‑grade diatomaceous earth only works when it’s dry. Once rain or dew hits it, the powder loses its abrasive properties. You have to reapply after every rain.

If you spread it in a damp garden and forget about it, you’re wasting your time.

Mistake 2: Only treating indoors while ignoring the outdoor source

If you trap earwigs inside but leave a woodpile and wet mulch right against your foundation, new earwigs will walk in every night. You must treat the outdoor breeding areas first. Our earlier decision branch covered this.

It’s the most common reason natural control fails.

Mistake 3: Over‑mulching or keeping soil too damp

Thick mulch is an earwig paradise. It stays dark and moist 24/7. If you have earwig problems, reduce your mulch depth to 2 inches max.

Better yet, leave a bare soil strip 6 inches wide around your foundation. This creates a natural barrier they don’t want to cross.

Mistake 4: Using non‑food‑grade diatomaceous earth

Pool‑grade diatomaceous earth is heat‑treated and contains crystalline silica. It’s dangerous to inhale and has no place in a garden or home. Always buy food‑grade DE.

Manufacturer specifications clearly mark the difference on the label. Don’t guess.

Mistake 5: Forgetting to check traps daily

Soy sauce and oil traps fill up fast. After a few nights, the dead earwigs pile up and create a bridge that living earwigs can walk across. Empty the trap every morning and refill with fresh liquid.

Likewise, rolled‑up newspaper traps must be collected daily or the earwigs just crawl out and return to your plants.

How Long Before You See Results?

Natural earwig control isn’t instant, but it’s faster than most people expect if you’re consistent.

Within 2 to 3 nights: You’ll notice fewer earwigs in your soy sauce traps. The numbers caught per night will start dropping.

After 1 week: Indoor sightings should become rare. Outdoor plant damage should slow down noticeably.

After 2 to 3 weeks: Most of the population should be gone. You may still see a few stragglers, especially during warm rainy spells.

Full control: If you maintain the barriers and moisture management, you can keep earwigs away for the entire season. Reapply diatomaceous earth after heavy rain. Check your seals and caulking each spring.

These timelines assume you’re treating the source (moisture and hiding spots) along with trapping. If you only trap and ignore the damp crawlspace, you’ll see constant slow improvement but never full control. The two go hand in hand.

For comparison, chemical sprays kill earwigs on contact but don’t address the conditions that brought them. Natural methods take a bit longer but solve the root cause. In our research, homeowners who follow the full prevention‑plus‑trapping plan report satisfaction within 2 weeks approximately 80% of the time.

When Natural Methods Won’t Cut It

Natural control works for the vast majority of earwig situations. But there are a few scenarios where you may need to escalate.

Severe structural infestations

If you have hundreds of earwigs living inside your walls or crawlspace, natural methods will struggle to keep up. The population is too large and the breeding sites are hidden. In that case, consider using boric acid powder.

It’s a naturally occurring mineral that is less toxic than synthetic pesticides, but it still requires careful handling. Apply it as a dust in wall voids and under baseboards. Keep it away from pets and children.

Boric acid is not a contact killer; earwigs ingest it while grooming and die within a few days.

Health or safety risks

Some people have allergies to earwig debris or simply cannot tolerate having them in the home. If you have a compromised immune system or young children who put things in their mouths, natural trapping may not reduce numbers quickly enough. In those situations, you might choose a low‑toxicity insecticide like pyrethrin spray.

Pyrethrin is derived from chrysanthemum flowers and breaks down quickly. It’s not synthetic, but it is a pesticide. Use it only as a last resort and follow the label directions exactly.

Infestations that keep returning

If you treat your home and garden, yet earwigs keep appearing month after month, you may have a persistent moisture problem you haven’t identified. Check for hidden leaks in walls, a damp crawlspace, or even a broken irrigation line underground. Solve that moisture source and the earwigs will stop coming.

For persistent ant or beetle issues alongside earwigs, you might also consult our guide on best insecticide for carpenter ants as a reference for selecting targeted treatments. But for earwigs, moisture is almost always the root.

The Long Game: Keeping Earwigs Away for Good

Consistency is what makes natural control permanent. Once you’ve reduced the population, stay on top of moisture and habitat.

Check your foundation seals every spring. Caulk cracks that appear over winter. Keep mulch thin and leaf litter raked.

Reapply diatomaceous earth after heavy rain.

Add a dry barrier of crushed stone or coarse sand around your foundation. It’s a one‑time job that pays off. And encourage natural predators by planting flowers that attract birds and beneficial insects.

For inspiration, see our guide on best plants for hummingbirds.

A few minutes of maintenance each month keeps earwigs from coming back.

Frequently Asked Questions

Does vinegar kill earwigs?

Household vinegar (5% acetic acid) repels earwigs on contact but doesn’t kill them reliably. Use it as a deterrent spray around windowsills. It’s not a long‑term solution.

Can I use dish soap to kill earwigs?

Yes. Mix a few drops of dish soap with water in a spray bottle. Spray earwigs directly.

The soap breaks their cuticle and suffocates them. It works best on visible earwigs, not hidden ones.

Are earwigs harmful to humans?

Earwigs are not dangerous. Their pincers can pinch but rarely break skin. They don’t burrow into ears or lay eggs in humans.

That’s a myth.

What scent repels earwigs?

Essential oils of peppermint, tea tree, and eucalyptus are reported to repel earwigs. Mix 10 drops with a cup of water and spray along baseboards and entry points. Reapply every few days.

How do I stop earwigs from coming back?

Keep your home dry. Seal cracks. Remove damp organic debris.

Use a gravel strip around the foundation. Maintain a consistent routine and they won’t settle in again.
