Earwigs in house can spoil a quiet night, especially in July through September. I’ve spent four years as a registered technician and our third-generation family business has served the DMV for over 50 years. I’ve seen many earwig issues and know how to tackle them.

Taxonomy and Key Pest Species: Understanding Earwigs in Your House
Earwigs belong to the order Dermaptera, family Forficulidae. The European earwig (Forficula auricularia) is the most common species in our region. According to NC State Extension, they have a flattened body and forceps-like cerci. For related information, see our House Crickets guide.
Life Cycle and Seasonal Activity of Earwigs in House
Earwigs produce one generation each year and overwinter in soil or debris. Females lay eggs underground and guard them until hatching. As noted by Virginia Tech Cooperative Extension, nymphs mature by late summer, driving peak activity.
Feeding Habits and Ecological Role of Earwigs in House
Earwigs are omnivores eating decaying plants, fungi, and small insects. They help control aphids and mites but can nibble on petals and seedlings. The University of Maryland Extension highlights their dual role in gardens.
How Earwigs in House Get Inside
Earwigs sneak in through gaps at doors, foundation joints, and unscreened vents. They also hitchhike in potted plants, firewood, and laundry baskets. Porch and flood lights attract them near thresholds. Learn more at How Do Earwigs Get In Your House & Ways To Keep Them Out.
Conducive Conditions That Attract Earwigs in House
Earwigs love moist mulch, clogged gutters, and leaky spigots. They hide under leaf piles, wood stacks, and dense groundcovers. Evening watering on soil surface boosts their activity. For additional guidance, see our article on House Flies.
Detecting Earwigs in House: Signs of Infestation
You might find single earwigs in bathrooms, basements, or laundry rooms. Check under doormats or cardboard for clusters. Outdoors, look for ragged leaf holes on plants. Night flashlight surveys agree with the University of Minnesota Extension findings.
Effective Pest Control: How to Get Rid of Earwigs in Your House
Cultural and Physical Controls
- Extend downspouts at least 6 ft from the foundation
- Repair ground slope to direct water away
- Thin mulch to 2 in. or replace with a gravel strip
- Remove leaf piles and wood stacks
Mechanical and Trapping Methods
- Use pitfall oil traps (tuna can + vegetable oil) and empty into soapy water each morning
- Set harborage traps with damp rolled newspaper or cardboard tubes
- Check traps daily until captures drop
You can find DIY trap photos at Nebraska Extension.
Biological Control Options
Ground beetles, toads, and birds eat earwigs naturally. However, biocontrol is limited in homes and not practical for full infestations.
Chemical Treatments
Use perimeter residual sprays (e.g., permethrin) on an 18-24 in. foundation wall band. Apply in late afternoon for fresh nighttime residues. Place granular or gel baits in mulch zones, separate from sprays. For indoor issues, apply spot treatments in cracks and crevices only if wanderers persist. Always follow label directions and EPA-approved products we trust.

Long-Term Prevention Blueprint: Protect Your Home from Earwigs
Seal all gaps with silicone caulk and install weather-stripping and door sweeps. Screen foundation and attic vents with 1/8 in. mesh. Keep mulch and plant beds at least 12 in. from siding. Swap bright bulbs for yellow “bug” LEDs near doors. Maintain gutters and adjust irrigation timing. For more tips, check Termite Prevention & Control.
