Monitor and tidy
One isolated sighting
No recurring location, moisture, damage or storm pattern.
- Remove the insect
- Check nearby doors and windows
- Watch for recurrence
The central decision guide
Why bugs keep getting inside your home
Indoor insects need a route, favorable conditions, or both. The useful question is not “What expensive repair does this prove?” It is “Which observable pattern best explains this activity?”
Begin with the least dramatic explanation
- Incidental entry: one insect near a door, window or item brought indoors.
- Repeatable access: sightings recur along the same threshold, wall edge or penetration.
- Favorable indoor conditions: moisture, shelter or food allows activity to persist.
- A broader home condition: independent signs of a leak, drainage problem or lower-level dampness appear with the insects.
Match the evidence to the next step
Pest exclusion or control
Repeated activity, but the area is dry
Multiple insects use the same visible entry area without moisture clues.
- Review screens, sweeps and gaps
- Reduce exterior shelter near the wall
- Consider a pest inspection if activity continues
Plumbing or leak evaluation
Activity plus localized wetness
Recurring insects appear with staining, swelling, drips or damp material near plumbing.
- Stop active water if safely possible
- Document the moisture location
- Choose a qualified plumbing or leak professional based on the water evidence
Drainage or moisture evaluation
Storm-linked lower-level pattern
Sightings repeatedly follow rain and occur with damp walls, standing water, mustiness or persistently wet perimeter soil.
- Check gutters, discharge and grading
- Record when and where water appears
- Seek an appropriate drainage, crawlspace or waterproofing evaluation if the moisture persists
Urgent conditions are about the home—not the earwig
Active water intrusion, electrical hazards near water, sewage, significant visible damage or rapidly spreading mold-like growth deserve prompt attention regardless of insect activity.
