how to get rid of earwigs

Most of us accept earwigs as a fact of life. We see them outdoors, and then we go our separate ways.

When earwig populations get out of control, though, it’s time to pay attention. Large numbers of earwigs can eat your plants and take over your space. Fortunately, you don’t have to live with earwigs forever.

Keep reading to learn how to get rid of earwigs for good with a combination of our top DIY earwig control methods.

How to Get Rid of Earwigs Inside & Outside Your Home

Natural Remedies

1. Build a DIY trap

Looking for a pesticide-free way to get rid of earwigs? Consider making a DIY trap. Here are a few different methods:

  • Cardboard or newspaper. One of the easiest methods to control earwigs is to use a magazine or rolled-up piece of cardboard and set it anywhere you’ve noticed earwig activity. Let it sit for a night. In the morning, pick it up and shake the earwigs into a bucket of soapy water, which will kill them.
  • Soap and water. Make a lighted earwig trap to kill earwigs at night when they’re most active. Fill a bucket with four parts of warm water and 1 part of dish soap. Stir the mixture until it’s foamy, and then place it on the floor with a lamp shining onto the water’s surface. The earwigs will be drawn to the light, drop into the water, and drown.
  • Soy sauce and oil. Pour equal parts soy sauce and vegetable oil into a plastic container. Seal the container and poke holes in the lid. The smell of the soy sauce will attract earwigs.
  • Beer containers and duct tape. Bury several half-empty containers of beer level with the groundline of your garden. The beer will attract the earwigs, who will fall in and drown. You can also use duct tape with its sticky side up to capture and trap earwigs.

Pros: Easy, effective, affordable, non-toxic

Cons: Requires hands-on contact with the pests 

2. Make a homemade earwig-killer spray

  • Make an alcohol-based earwig-killer spray by mixing equal parts rubbing alcohol and water in a clean spray bottle. Spray earwigs directly with the spray. The alcohol will penetrate the earwig’s protective coating and kill it immediately.
  • You can also use a spray bottle of warm water mixed with a few drops of dish soap. Spray the mixture onto the leaves of plants or in the damp corners of basements or crawl spaces.
  • Use essential oils. Simply mix 15 drops of the oil of your choice into 4 ounces of water. Spray the mixture anywhere you’ve noticed earwigs. While the mixture will not kill earwigs, it will repel them.
  • Use vinegar. You can also mix ¼ cup white vinegar with a few drops of dish soap in a spray bottle. This mixture will kill earwigs but shouldn’t be used on plants since it will kill them.

Pros: Easy, affordable, effective, non-toxic

Cons: Requires you to see and treat earwigs on contact, essential oils will not kill earwigs, and vinegar may burn plants 

3. Use boric acid

Boric acid is a highly effective, natural insecticide that can kill earwigs on contact. Sprinkle boric acid in high-traffic areas where earwigs are likely to crawl through it.

Pros: Effective, fast-acting, kills earwigs on contact

Cons: Not safe for use around kids or pets

4. Vacuum up earwigs

Suck up adult earwigs on contact and go back over the area where you found them to collect any eggs that may be left behind.

Dispose of the vacuum bag in a tightly-sealed trash bag or empty the vacuum container into a bucket of soapy water to kill the bugs.

Pros: Removes adult earwigs, their eggs and larvae, and their food sources

Cons: Will not eradicate hidden earwig populations

5. Try the Cotton ball soak method

Essential oils like citronella, lavender, and cinnamon can eliminate earwigs.

Simply place 3-4 drops onto a cotton ball and put the cotton ball anywhere you’ve noticed earwig activity. The scent is so strong it will keep earwigs from coming back.

Pros: Easy, affordable, effective, non-toxic

Cons: Will not kill earwigs

6. Reduce moisture

Reducing moisture will make your space less attractive for earwigs and other pests.

Here are a few tips:

  • Fix any plumbing leaks, including leaks under sinks and indoor faucets or broken and leaky irrigation systems.
  • Clean gutters and downspouts, which create damp places for earwigs to live. Additionally, ensure they’re draining properly away from your house to prevent water buildup that could attract earwigs.
  • Avoid overwatering indoor and outdoor plants.
  • Use a dehumidifier to remove excess moisture in your basement or crawl space.

Pros: Easy, effective, will reduce the numbers of earwigs and other pests, will protect your home from water damage, mold, and mildew

Cons: Will not kill earwigs

7. Remove or secure food sources

Earwigs are attracted to crumbs of human food and will infest pantries and kitchens.

With this in mind, keep all potential food sources in airtight containers, clean up spills promptly, empty pet food routinely, and deep clean food preparation areas regularly.

Pros: Will make your space less appealing for all pests and promotes overall home hygiene 

Cons: Will not kill existing earwigs, their eggs, or larvae

8. Seal cracks and gaps

Keep earwigs out of your home by using latex caulk to seal gaps and crevices around your windows, doors, and the foundation of your home. Repair or install screens and avoid leaving doors and windows open.

We also recommend adding door sweeps like these, which seal the gap beneath your door, keeping earwigs, drafts, and other bugs out of your home.

Pros: Easy, affordable, effective, non-toxic

Cons: Labor-intensive, requires annual maintenance 

9. Clean up your yard

Remove earwig hiding places by removing leaf piles, fallen organic matter, excess vegetation, and woodpiles.

Keep mulch, dead leaves, and other vegetation at least 12” away from your home’s foundation, and trim shrubs to eliminate damp, shady areas near the house.

Pros: Reduces populations of earwigs and other pests and makes them less likely to come indoors

Cons: It takes a long time to control existing earwig populations effectively

10. Diatomaceous earth

Diatomaceous earth

Diatomaceous earth kills earwigs and other soft-bodied pests without toxins or harsh pesticides.

To control earwigs outdoors, sprinkle DE around the roots of your potted plants or crops or in garden areas where earwigs have been common.

Pros: Effective, affordable, non-toxic, fast-acting, suitable for controlling earwigs and other pests

Cons: Requires regular re-application 

11. Natural predators

Looking for a pet-friendly way to get rid of earwigs?

Attract natural predators like frogs, wolf spiders, centipedes, birds, and tachinid flies, which will consume earwigs and help keep populations in check.

Pros: Effective, affordable, safe for kids, pets, and the environment 

Cons: Not a fast-acting solution

12. Naturally-derived pesticides

If you want to get rid of earwigs, you don’t always have to invest in hard-hitting chemicals. Instead, you can use products made from naturally derived compounds.

Two options we like are Essentria IC-3, which is a perimeter spray designed for use around the outside of your home, and Essentria Contact Spray, which is effective for use around the doors and windows of your home.

Pros: Non-toxic, safe for use around kids and pets

Cons: Requires regular re-application

13. Artificial drought

One easy way to get rid of earwigs in your garden is to keep the soil as dry as possible between watering cycles.

Because earwigs thrive on moisture, creating an artificial drought can make the area inhospitable for them and help control earwig populations.

Pros: Easy, effective, non-toxic

Cons: May not be feasible during hot or dry periods of the year, when plants will wilt and die without adequate water

Chemical Methods

14. Use Pesticides

The most effective earwig pesticides contain spinosad, sevin, malathion, or pyrethrins. These pesticides come in a variety of formats, including sprays and granules.

To kill earwigs, spray these pesticides anywhere you’ve noticed earwig infestation, being careful to adhere to all label directions.

For best results, apply the pesticides at night and combine chemical control methods with trapping and sanitation protocols.

Pros: Effective, fast- and long-acting

Cons: May not be safe for use around kids or pets, may contain toxic ingredients

15. Create a barrier

Create an insect-proof barrier around your home by using a perimeter pesticide.

Spray it around the outside of your house, as well as around your window and door casings and along baseboards.

This will kill earwigs and other bugs before they get a chance to come indoors.

Pros: Proactive, practical, good for preventing pests from entering the home

Cons: Requires regular reapplication

16. Granular pesticides and bait

While we don’t recommend spraying your yard with a liquid insecticide since this can kill beneficial insects and other non-target species, scatter baits like Niban granular bait are an effective, targeted way to get rid of earwigs.

Niban granular bait is designed for application in yards and gardens. It works when pests ingest the formula. This product contains 5% boric acid and targets a variety of garden pests, including earwigs, cockroaches, crickets, and ants.

To use granular pesticides, add them to a lawn spreader and take a few laps around your outdoor space.

When you water the granules, they release their active ingredients and kill earwigs on contact.

Pros: These products are quick-acting and easy to use, they kill earwigs quickly

Cons: These products must be reapplied regularly – especially after rain

Earwig Control FAQs

Earwigs, also known as pincher bugs, are mean-looking insects native to Europe. Adults are about ¾” long with reddish-brown bodies and forceps-like pinchers on the ends of their abdomen.

The pinchers of males are thick, curved, and slightly separated, while females have straighter, thinner pinchers. Immature earwigs are smaller than adults but similar in appearance.

Earwigs are mostly nocturnal. They hide during the day in damp, moist, shaded areas of your home or garden and are active at night.

There are more than 2,000 species of earwigs worldwide and about 35 in North America. The most widespread is the common earwig.

While earwigs look menacing, they’re unlikely to harm people. If attacked or threatened, an earwig may use its pincers to pinch a human, but the pincers don’t usually break the skin, and adverse reactions are rare in people.

In homes, earwigs are a nuisance, upsetting your peace of mind but not doing any real damage. In small numbers, earwigs may benefit your garden, consuming other mites and other pests and keeping plants healthy.

However, when earwig populations grow out of control, they feed on plant leaves, flowers, fruits, and buds. Swarms of earwigs can quickly decimate your garden, destroying young seedlings and causing large, irregular holes in plants.

If you’ve suddenly noticed high concentrations of earwigs in your home, yard, or garden, here are a few things that may be attracting them:

1. Food

Earwigs love to eat soft, dying organic matter. In their natural habitats, earwigs eat leaves, flowers, fruits, buds, and other insects, including mites, aphids, and insect eggs.

Inside, an earwig’s diet includes man-made, high-starch food sources, such as flour, bread, and cookies.

2. Shelter

Outside, earwigs shelter in damp, moist areas, like the space between a flowerpot and saucer, or in rotting organic matter.

Earwigs can’t live through harsh winter conditions, so they find their way indoors when the temperatures change.

3. Moisture

Inside, earwigs are often found living in the trays of potted plants or damp, moist areas like the space under the sink.

They’re also common in basements and crawl spaces. Outside, they live under decaying leaf matter, mulch, or bark.

If you’re unsure whether you have an earwig infestation, look for these common signs:

  • Foul smells. When scared or threatened, earwigs produce a yellow-brown secretion to ward off predators. While this secretion smells bad, it’s harmless to people. Another warning sign is a musty, moldy odor. Since earwigs congregate in damp areas, which are also prone to mold and mildew development, smelling mold may signify that ideal earwig habitat exists in your home.
  • Dead plants and gnawed leaves. Outdoors, you may notice signs of earwig predation in your garden, especially on new growth. Pay close attention to any plants that are wilted, yellowed, or that suddenly have holes in their leaves. Inside, you may see holes in the leaves of your potted plants.
  • Earwig sightings. The best way to confirm an earwig infestation is to see the insects within your home. Since these pests are nocturnal, you can spot them by using a bright light at night (earwigs are attracted to the glow) or by inspecting their hiding places, which tend to be basements, crawl spaces, the trays of potted plants, and other dark, moist areas.
  • Earwig droppings. Earwig droppings are tiny, cylindrical, and black. They can be found near earwig hiding spots and are especially common in damp, dark corners and crevices.

Earwigs will seek out moist, dark places to nest once indoors. You’ll usually find them under kitchen and bathroom sinks or in basements and crawl spaces.

No. Earwigs have no venom and do not bite or sting. They are not poisonous to humans and are not known to spread harmful bacteria.

While some people claim that coffee grounds repel earwigs, there’s no evidence to suggest that’s true. We recommend using proven methods, like chemical and homemade repellents and traps.
