Narrow down where mice are getting in

01

Narrow the search before you name the route

If you are trying to find where mice are getting in, do not read one night of playback as a finished route map. Use it to make the next physical inspection smaller and more deliberate.

A total tells you how much motion the sensors recorded. Playback adds order: which positioned sensor triggered first, which followed, and where the last detection occurred before the record went quiet. The edges can provide a better field question than the busiest sensor alone.

02

Anchor every label to the floorplan

Sensor A only becomes useful evidence when everyone knows where Sensor A was placed. Record height, orientation, and the nearby building feature when those details affect what the sensor can detect.

• Confirm each sensor label before the monitoring night.
• Mark moved or obstructed sensors before comparing results.
• Read timestamps alongside position, not as an isolated event log.

03

Move toward the unanswered edge

If the earliest repeated detections cluster near one side of the monitored area, reposition a small number of sensors beyond that edge. If the latest repeated detections leave through another boundary, test that edge separately rather than assuming the two points establish direction.

The purpose is to ask a narrower question on the next night—not to manufacture a smoother path or declare the opening before the building supplies proof.

04

Finish with the building

Inspect the narrowed area for an actual opening or route. The floorplan playback directs attention; the physical condition establishes what should be repaired, sealed, or tested next.
