Earwigs: Detailed Information, Bites, and Prevention
1. Overview of Earwigs
- Scientific Name: Order Dermaptera
- Common Name: Earwig
- Size: Typically 5–25 mm (0.2–1 inch) long, depending on the species
- Appearance:
- Long, flattened body
- Large pincers (cerci) at the rear, used for defense and capturing prey
- Two pairs of wings, though not all earwigs fly
- Found worldwide, especially in warm, moist environments
- Often hide in dark, damp places like under rocks, leaves, and woodpiles
- Can enter homes seeking food, moisture, or shelter
2. Do Earwigs Bite? What Happens If They Pinch You?
Earwigs do NOT bite humans because they lack venom and fangs. However, they can pinch using their cerci (forceps-like pincers).
- What Happens If an Earwig Pinches You?
✔ Usually harmless, though it can cause mild pain and irritation.
✔ In rare cases, it may break the skin, leading to redness or minor swelling.
✔ No venom or toxins are involved, so no serious health risk exists.
- What to Do If You Get Pinched?
✔️ Clean the area with soap and water to prevent infection.
✔️ Apply ice or a cold compress to reduce swelling.
✔️ Use an antiseptic if the skin is broken.
✔️ If pain or irritation persists, apply a mild hydrocortisone cream.
3. Why Are Earwigs in Your House?
Earwigs enter homes in search of food, moisture, and shelter. Common attractants include:
✔ Damp areas (bathrooms, basements, kitchens)
✔ Rotting wood, cardboard, or decaying plants
✔ Bright lights at night, which can attract them indoors
✔ Cracks and openings in doors, windows, and walls
4. How to Get Rid of Earwigs in the House
If you have an earwig infestation, try these methods:
- Immediate Removal:
✅ Vacuum them up and dispose of the vacuum bag.
✅ Trap them using damp rolled-up newspaper (they hide inside overnight, then you can dispose of it in the morning).
✅ Use a shallow dish of oil and soy sauce as a trap—earwigs are attracted to it and drown.
- Natural Repellents:
✔ Diatomaceous earth (DE): Sprinkle around moist areas to kill earwigs.
✔ Boric acid: Acts as a natural insecticide when spread near their hiding places.
✔ Essential oils (like peppermint or lavender): Spray around entry points to deter them.
- Chemical Methods:
If the infestation is severe, consider insecticidal sprays or professional pest control.
5. How to Prevent Earwigs from Coming Back
- Eliminate Moisture:
✅ Fix leaky pipes or faucets.
✅ Use a dehumidifier in damp areas.
- Seal Entry Points:
✅ Close gaps in doors, windows, and walls.
✅ Install tight-fitting screens on windows and vents.
- Reduce Outdoor Attractants:
✅ Reduce outdoor lighting at night, as it attracts earwigs.
✅ Keep yard debris, mulch, and firewood away from the house.
Earwigs are harmless insects despite their intimidating pincers. They do not bite but may pinch if threatened. If you find them in your home, you can trap, remove, or repel them using natural or chemical methods. Prevent future infestations by eliminating moisture, sealing entry points, and keeping outdoor areas clean.
