What is a common method used to monitor the effectiveness of fumigation?

Using gas concentration monitors is a common method employed to monitor the effectiveness of fumigation. These devices measure the concentration of fumigants in the air, which allows applicators to assess whether adequate exposure levels have been achieved throughout the fumigation process. Monitoring gas concentration is crucial because it helps ensure that the fumigant penetrates properly into the targeted areas and that it remains at effective levels for the necessary duration. This real-time data can help operators make informed decisions during the fumigation and ensure compliance with safety regulations.

In contrast, visual inspections, waiting for several days to assess pest activity, or solely conducting interviews with clients do not provide immediate or accurate insights into the effectiveness of the fumigation process. While visual inspections may help identify initial results post-fumigation, they do not give a comprehensive view of how well the treatment was executed or if the appropriate concentration of the fumigant was maintained. Similarly, relying on subjective methods such as client interviews can lead to variable interpretations and may not reflect the true effectiveness of the fumigation.
