How to Get Rid of Earwigs With One Simple Ingredient
Earwigs are small, nocturnal insects that can be surprisingly bothersome in gardens and homes. They’re most famous for their pincer-like tails, but while they aren’t harmful to humans, they can damage plants, flowers, and vegetables. Fortunately, you don’t need harsh chemicals to control them—sometimes, one simple ingredient is all it takes.
The Secret Ingredient: Diatomaceous Earth (DE)
Diatomaceous earth is a fine, powdery substance made from fossilized remains of tiny aquatic organisms called diatoms. It’s safe for humans and pets, but deadly for soft-bodied insects like earwigs.
How it works:
- The microscopic particles of DE cut through the insect’s exoskeleton
- It absorbs moisture, causing the earwig to dehydrate and die
- It’s effective without harmful chemicals
How to Use Diatomaceous Earth Against Earwigs
- Identify Problem Areas
Earwigs love damp, dark, and sheltered spaces:- Under mulch or leaves
- Around flower beds
- Near foundations or garden edges
- Apply a Thin Layer
Sprinkle DE around plants, pathways, or anywhere you’ve noticed earwig activity. Focus on places where they hide during the day. - Reapply After Rain
Diatomaceous earth loses effectiveness when wet. Reapply after rain or heavy watering. - Use Around the Home
For indoor infestations, sprinkle a light layer near windows, doorways, and basements—but avoid direct contact with food prep surfaces.
Additional Tips for Earwig Control
- Reduce Moisture: Earwigs thrive in damp areas, so avoid overwatering and remove standing water.
- Clear Debris: Keep mulch, leaf piles, and garden debris away from the house perimeter.
- Use Traps: Roll-up newspapers or damp cardboard can attract earwigs. Dispose of the traps in the morning.
Why DE Is a Smart Choice
- Non-toxic: Safe for children, pets, and beneficial insects when used carefully
- Long-lasting: Remains effective as long as it stays dry
- Affordable: A small amount goes a long way
The Bottom Line
If you’re battling earwigs, diatomaceous earth is a simple, effective, and safe solution. By targeting their hiding spots and reducing moisture, you can keep your garden and home largely earwig-free—without resorting to harsh pesticides.
Sometimes, the simplest ingredient can make the biggest difference.
