Earwigs can be frustrating when they show up in bathrooms, basements, flower beds, vegetable gardens, or potted plants. While they are not usually dangerous to people, they can become a nuisance indoors and may damage tender plants outdoors. The best way to kill earwigs is to combine traps, moisture control, direct treatment, and prevention so they do not keep coming back.
What Attracts Earwigs?
Earwigs are drawn to damp, dark, protected areas. They hide during the day and come out at night to feed. Around homes, they often gather under mulch, leaves, stones, flowerpots, wood piles, and garden debris.
Inside the house, earwigs are most common in areas with moisture. Bathrooms, kitchens, basements, laundry rooms, garages, and crawl spaces are typical places to find them. If you keep seeing earwigs indoors, they are likely entering from outside or surviving in damp indoor hiding spots.
Are Earwigs Harmful?
Earwigs look intimidating because of the pincers on the back of their bodies, but they are not considered a major threat to people. They do not spread serious diseases and are not known for causing structural damage.
However, they can pinch if handled, create an unpleasant indoor pest problem, and damage some plants. In gardens, they may chew holes in leaves, petals, soft fruit, seedlings, and vegetables.
How to Kill Earwigs Fast
If you want to kill earwigs fast, start with the ones you can see, then treat the places where they hide. Killing individual earwigs is simple, but controlling an infestation takes a broader plan.
Use Soapy Water Spray
A soapy water spray can kill earwigs on contact. Mix water with a small amount of dish soap in a spray bottle, then spray earwigs directly when you see them. This method is useful indoors, outdoors, and around patios.
Be careful when using soapy water on plants. Test it on a small section first, because some delicate plants may react badly to soap sprays, especially in hot sun.
Vacuum Them Indoors
For earwigs inside the house, vacuuming is one of the easiest control methods. Use a vacuum along baseboards, under sinks, behind appliances, around basement corners, and near exterior doors.
After vacuuming, empty the contents into a sealed bag and dispose of it outside. This helps prevent live earwigs from escaping back into your home.
Use Sticky Traps
Sticky traps can catch earwigs in places where they travel. Place them along walls, under sinks, behind toilets, near laundry areas, in basements, and around garage doors.
Sticky traps are especially useful because they help you see where earwigs are most active. If many are caught in one location, that area may have a moisture problem or nearby entry point.
Best Ways to Kill Earwigs
Different earwig problems require different control methods. A few earwigs in a bathroom may only need vacuuming and sealing. A garden infestation may need traps, habitat cleanup, and plant protection.
| Method | Best Use | Notes |
| Soapy water spray | Fast contact kill | Works only when sprayed directly |
| Oil and soy sauce trap | Garden and outdoor control | Attracts and traps earwigs overnight |
| Diatomaceous earth | Dry cracks and hiding areas | Must stay dry to work well |
| Sticky traps | Indoor monitoring and capture | Good for basements, bathrooms, and garages |
| Professional treatment | Heavy infestations | Best for recurring or widespread problems |
How to Kill Earwigs in the House
Killing earwigs in the house starts with finding where they are entering and why they are staying. Indoor earwigs usually come from damp outdoor areas, but moisture inside the home can keep them active.
Check Common Indoor Hiding Places
Earwigs hide in dark, tight areas during the day. Look carefully in rooms where moisture is common.
Check these places:
- Under bathroom sinks and kitchen sinks
- Around tubs, showers, toilets, and drains
- Behind washing machines and water heaters
- Along basement walls and floor cracks
- Around garage doors and storage boxes
- Near exterior doors, windows, and sliding doors
If you find many earwigs in one room, look for leaks, condensation, poor ventilation, or cracks near the outside wall.
Kill Indoor Earwigs Safely
For indoor control, avoid spraying strong pesticides across open living areas. Use targeted methods first. Vacuum visible earwigs, place sticky traps, and spray soapy water directly on pests when needed.
You can also apply diatomaceous earth lightly in dry cracks, wall void edges, or hidden areas where earwigs travel. Do not place dust where children or pets can disturb it, and avoid breathing it in during application.
Seal Entry Points
Killing earwigs indoors will not solve the problem if more keep entering. Seal gaps around windows, doors, pipes, utility lines, vents, and foundation cracks.
Install door sweeps, repair torn screens, replace damaged weatherstripping, and seal openings with caulk. Pay special attention to basement windows, garage doors, and patio doors.
How to Kill Earwigs in the Garden
Garden earwig control requires balance. Earwigs can eat decaying matter and some pests, but they can also damage flowers, vegetables, seedlings, and soft fruits when populations grow too large.
Use Oil and Soy Sauce Traps
One of the best ways to attract and kill earwigs is with an oil trap. Fill a shallow container with vegetable oil and add a small amount of soy sauce. The scent attracts earwigs, and the oil traps them.
Place the trap near damaged plants, mulch, raised beds, or flowerpots overnight. In the morning, dispose of the trapped earwigs and refresh the mixture as needed.
Use Rolled Newspaper Traps
Earwigs like dark, damp hiding spots. Roll up damp newspaper or cardboard and place it near affected plants in the evening. Earwigs will crawl inside overnight.
In the morning, collect the roll and dispose of the insects. This method is useful for organic garden pest control and works well around flower beds and vegetable gardens.
Protect Plants Without Harming Them
If you want to kill earwigs without harming plants, avoid harsh, broad spraying. Focus on traps and habitat cleanup first.
Helpful steps include:
- Remove dead leaves and fallen fruit
- Keep mulch away from plant stems
- Avoid overwatering garden beds
- Lift pots and planters to check underneath
- Use traps near seedlings, dahlias, roses, petunias, and vegetables
- Water early in the day so soil surfaces dry before night
This approach reduces earwig numbers while lowering the risk of plant stress.
How to Kill Earwigs Naturally
Natural earwig control is a good choice for gardens, homes with pets, and areas where you want to avoid heavy pesticide use. Natural methods work best when used consistently.
Diatomaceous Earth
Diatomaceous earth can kill earwigs by damaging their outer coating, which causes them to dry out. Apply a thin layer in dry areas where earwigs crawl, such as cracks, wall edges, under dry planters, and around outdoor hiding spots.
So, how long does diatomaceous earth take to kill earwigs? It usually does not work instantly. It may take several hours to a few days, depending on contact, humidity, and how much the earwigs move through the dust. It works best when completely dry.
Boric Acid and Borax
Some people ask how to use borax or boric acid to kill earwigs. These substances may affect insects, but they should be used with caution. Boric acid and borax can be harmful if misused, especially around children, pets, food areas, and garden soil.
If using a product that contains boric acid, follow the label exactly. Do not sprinkle household borax randomly around the home or garden. For most homeowners, traps, moisture control, and diatomaceous earth are safer first steps.
Soapy Water and Oil Traps
Soapy water works as a direct contact spray, while oil traps work by attracting and drowning earwigs. These two methods are among the easiest natural ways to kill earwigs at home.
Use soapy water when you see earwigs directly. Use oil traps overnight in gardens, patios, and outdoor problem areas.
How to Kill Earwigs Outside
Outdoor earwig control is important because most indoor problems begin outside. If earwigs are breeding and hiding around your foundation, they can keep entering your home.
Remove Outdoor Shelter
Earwigs gather where it is dark and damp. Reducing shelter can make your yard less attractive.
Clean up these areas:
- Leaf piles near the house
- Thick mulch against the foundation
- Firewood stacked on the ground
- Boards, stones, and unused pots
- Wet cardboard, garden debris, and weeds
- Clutter around patios, sheds, and garages
Keep a dry, clear strip around your foundation when possible. This makes it harder for earwigs to hide near entry points.
Reduce Moisture Outdoors
Moisture is one of the biggest reasons earwigs gather outside. Fix drainage issues, clean gutters, extend downspouts, and avoid overwatering plants near your home.
If garden beds stay wet for long periods, reduce mulch depth or switch to a less moisture-holding border near the foundation.
How to Kill an Earwig Infestation
An earwig infestation usually means there are many hiding places, moisture sources, or entry points. To control a larger problem, you need more than one method.
Start by vacuuming indoor earwigs and setting traps. Then inspect the outside of your home. Remove mulch buildup, leaves, wood, and debris. Seal gaps around doors, windows, vents, pipes, and cracks. Use oil traps in the garden and sticky traps indoors.
If the infestation continues after these steps, consider professional pest control. A technician can identify the main source, apply targeted treatments, and recommend changes to prevent future infestations.
How to Prevent Earwigs After Killing Them
Once you reduce the current earwig problem, prevention keeps them from returning. Earwigs are easier to prevent than to eliminate after they spread through the home or garden.
Use these prevention steps:
- Fix leaking pipes and outdoor faucets
- Use dehumidifiers in damp basements
- Keep gutters clean and draining properly
- Seal cracks around the foundation
- Repair screens and weatherstripping
- Store firewood away from the house
- Remove wet leaves, mulch, and debris
- Keep outdoor lights away from entry doors when possible
- Check potted plants before bringing them indoors
The most effective long-term solution is to make your property less damp and less sheltered.
