How can I know that bed bugs have been eradicated? - briefly
Examine mattress seams, box‑spring folds, bed frames, and nearby furniture for live insects, shed skins, or dark spotting; any such evidence shows the problem remains. Confirmation requires a professional inspection using specialized detection equipment or trained canine units.
How can I know that bed bugs have been eradicated? - in detail
After a treatment program, verification relies on systematic observation and monitoring.
Inspect all sleeping areas, furniture seams, and baseboards for live insects, exuviae, or dark fecal spots. The presence of any of these indicators suggests a remaining population.
Deploy passive devices such as interceptors placed under each leg of the bed and furniture. Check them weekly; an absence of captures for a minimum of four weeks supports the conclusion of elimination.
Consider active monitoring tools, including sticky traps and pheromone‑based lures, positioned near potential harborages. Consistent negative results over several weeks reinforce confidence in success.
Professional confirmation adds credibility. Request a written clearance from a certified pest‑management specialist, who should conduct a final inspection and document the lack of activity.
Maintain a routine of periodic checks for at least three months following the declared clearance, because dormant eggs may hatch later. Continuous absence of evidence during this interval confirms that the infestation has been fully resolved.
