Show a customer what changed after the work
Compare like-for-like monitoring nights to explain what changed after corrective work and what still needs inspection.
Establish a readable baseline
Before corrective work, record the monitoring window, sensor positions, and activity pattern. The baseline should be simple enough that the account executive, customer, and field lead can understand what will be compared later.
Mark what changed between nights
Note the date and location of exclusion, sanitation, trapping, or placement changes. Without that note, a before-and-after chart can hide other changes that affected the detections.
Compare like with like
Keep sensor position and monitoring duration stable when possible. Review total detections, timing, and where activity concentrated rather than choosing whichever number tells the best story.
- Same position and orientation.
- Comparable monitoring window.
- Placement changes clearly labeled.
- Physical inspection included in the follow-up.
State the result at the right level
“Recorded activity fell near the repaired penetration on the next two monitoring nights” is useful and reviewable. “The problem is permanently solved” goes beyond what those nights establish.
Sources and scope
What a sensor record can’t establish: A lower count supports a change in recorded activity; it does not prove permanent resolution.
Compare defined monitoring windows before and after a dated intervention. Keep positions, orientation, and duration as comparable as possible; log changes, outages, and physical findings; then interpret a change in recorded detections alongside on-site inspection. EPA IPM guidance emphasizes accurate records for evaluating results, and the CDC survey manual describes baseline and periodic resurveys for assessing progress. The record supports a change in recorded activity, not a permanent all-clear.
