What Are Earwigs?
Earwigs are insects with long, thin bodies. They have pincers on their back ends. These pincers look like small claws. Earwigs are mostly brown or black. They like moist places like under leaves, stones, or wood. Sometimes, they come inside houses, especially in basements or bathrooms.
Earwigs eat plants and small insects. They can damage flowers, fruits, and vegetables. Though earwigs do not bite people or spread diseases, many find them scary or annoying.
What Is Borax?
Borax is a natural mineral. It is also called sodium borate. People often use borax for cleaning and laundry. It can kill some insects like ants and cockroaches. Borax works by harming the insect’s body when they eat it or walk on it.
You can find borax in powder form. It looks like white salt or sugar. Because borax can be harmful if swallowed by people or pets, it must be used carefully.
How Does Borax Kill Insects?
Borax affects insects in two main ways:
- It dries out their bodies: Borax can damage the insect’s outer shell. This shell protects their body from water loss. When the shell is damaged, the insect loses water and dies.
- It poisons their digestive system: When insects eat borax, it harms their stomach and guts. This stops them from eating or digesting food. They become weak and die.
Does Borax Kill Earwigs?
Many people ask if borax kills earwigs. The short answer is yes, but with some limits.
Earwigs do not eat borax directly. They mostly eat plants and other insects. So, borax powder alone may not kill earwigs quickly. However, borax can work if earwigs walk over it. The powder sticks to their bodies and dries them out.
Also, if you mix borax with bait (like sugar or oil), earwigs may eat it. This can poison them inside. But this method is less common. It is not easy to make bait that earwigs will eat regularly.
How to Use Borax to Control Earwigs
If you want to try borax for earwigs, here are some steps you can follow:
- Find where earwigs hide: Look for dark, wet places like under rocks, leaves, or wood.
- Clean the area: Remove leaves, mulch, and debris where earwigs live.
- Apply borax powder: Sprinkle a thin layer of borax in these spots. Be careful not to use too much.
- Keep the area dry: Earwigs like moisture. If you keep the area dry, borax works better.
- Use bait if needed: Mix borax with sugar or syrup to attract earwigs. Place the bait where you see earwigs.
Remember, borax takes time to work. You may not see results immediately. Be patient and repeat the process as needed.

Other Ways to Get Rid of Earwigs
Borax is one option. But there are other ways to reduce earwigs in your home or garden.
1. Remove Moisture
Earwigs love damp places. Fix leaks and use a dehumidifier inside your home. Outside, avoid overwatering plants.
2. Use Barriers
Place sticky tape or diatomaceous earth around plants. These stop earwigs from reaching your plants.
3. Trap Earwigs
You can make simple traps. Use rolled-up newspapers or damp cardboard. In the morning, shake the traps into soapy water to kill earwigs.
4. Natural Predators
Some animals eat earwigs. Birds, toads, and spiders help control their numbers.
5. Chemical Insecticides
If earwigs are many, use insecticides labeled for earwigs. Follow instructions carefully to stay safe.
