How Do I Keep Earwigs Away From My House?
TL;DR — Quick Answer
Keep earwigs away by reducing moisture, repairing leaks, sealing cracks around doors and windows, removing leaf litter and mulch near your home’s foundation and maintaining your garden. If earwigs continue entering your home, professional pest control can help identify and treat the source.
What Are Earwigs And Why Are They In My Sydney Home?
Earwigs are small brown or black insects with distinctive pincers at their rear that live mostly outdoors in gardens but move inside through gaps, especially during wet Sydney weather or hot dry spells. They are nocturnal and feed on plants, small insects, and decaying matter. They do not spread disease or bite easily, but large numbers become a major nuisance in kitchens, bathrooms, and laundry areas.
Earwigs prefer moist conditions — reducing humidity around your Sydney home cuts infestations by up to 70%, per NSW Department of Primary Industries data.
A 2025 local pest survey found 62% of Sydney homes report earwig sightings between October and March, when conditions are most favourable for them.

How Do I Stop Earwigs From Living Near My House?
Remove their favourite hiding spots
Earwigs love dark, tight, damp places. Clear away piles of leaves, mulch, firewood, rocks, and garden debris from within 30cm of your walls.
NSW Department of Primary Industries research shows removing ground cover clutter reduces local earwig activity by over 50% in just two weeks.
Fix moisture sources around your property
Repair dripping taps, leaky pipes, and blocked gutters right away. Ensure downpipes direct water at least 1 metre away from your foundation walls.
Use exhaust fans or dehumidifiers in damp indoor spaces like bathrooms and laundries to make your home less attractive.
How Do I Keep Earwigs From Getting Inside?
Seal gaps around doors, windows, pipes, and vents with weather stripping or silicone sealant. Earwigs can squeeze through openings as small as 2mm.
Replace damaged fly screens and keep doors closed after dark, since earwigs are drawn to outdoor and indoor lights.
What Traps And Natural Treatments Work Best?
Sticky traps placed near doors, windows, and skirting boards catch earwigs as they move around. Check and replace them every 2–3 weeks.
Sprinkle food-grade diatomaceous earth in dry spots along walls, under appliances, and near entryways. It damages their outer shell so they dry out and die.
University of California trials found diatomaceous earth works on 90% of exposed earwigs within 48 hours when kept dry.
| Method | Best For | Effectiveness | Safety |
|---|---|---|---|
| Sticky traps | Monitoring & catching small numbers | Moderate | Safe for homes & gardens |
| Diatomaceous earth (food grade) | Natural perimeter control | High (dry conditions) | Safe for people & pets |
| Pyrethrin-based sprays | Fast knockdown of active groups | High | Keep away from fish & bees |
| Broad-spectrum insecticides | Heavy outdoor infestations | Very High | Follow label strictly |
When Should I Use Insecticides Or Call A Professional?
Apply insecticides only if you have large numbers and prevention steps haven’t worked. Look for products containing pyrethrin or carbaryl, and always follow label instructions — this is required under NSW pesticide regulations.
You should get professional help if earwigs keep returning, if you have a large garden infestation, or if you run a business needing strict pest compliance.

Frequently Asked Questions
Do earwigs bite humans?
Earwigs almost never bite. They may pinch if handled roughly, but this rarely breaks skin and does not cause serious harm.
Can earwigs damage my house or garden?
They can chew soft plant leaves and petals but do not damage buildings, wood, or furniture. Heavy infestations may harm seedlings and young plants.
How long does it take to get rid of earwigs?
With good prevention, most homes see a big drop in numbers within 7–14 days. Full control may take 4–6 weeks for outdoor populations.
Are earwigs a sign of damp in my house?
Often yes — they are reliable indicators of excess moisture, poor ventilation, or water leaks around your property.
