Why Earwigs Invade Spokane Homes
Earwigs are generally harmless insects, but their presence in homes can be concerning due to sheer numbers.
1. Moisture and Humidity
- Earwigs need damp environments to survive
- Leaky pipes, wet basements, and condensation attract them
- Homes with poor drainage or high humidity are especially vulnerable
2. Outdoor Habitat Proximity
Earwigs live under:
- Mulch, leaves, and wood piles
- Rocks and garden debris
- Flower beds and shrubs near foundations
Homes surrounded by these conditions are more likely to see earwig invasions.
3. Seasonal Activity
- Spring: Earwigs emerge after winter dormancy
- Fall: They seek shelter before colder weather
- Rainy periods increase indoor sightings
4. Easy Entry Points
Earwigs are small and flexible:
- Cracks in foundations
- Gaps around doors and windows
- Vent openings and siding gaps
Even minor openings can allow large numbers to enter.
5. Attraction to Light
- Earwigs are nocturnal but may be drawn to exterior lights
- Outdoor lighting can increase activity near doors and windows
Are Earwigs Harmful?
The good news:
- Earwigs do not bite humans
- They do not cause structural damage
- They may feed on plants or occasionally paper products, but damage is minimal
However, a large number inside the home can be alarming and annoying.
