What are some common indicators that fumigation is complete?

The completion of fumigation is typically indicated by a combination of factors, with a significant focus on both the drop in pest populations and monitored gas levels. After fumigation, a noticeable decrease in pest populations would suggest the effectiveness of the treatment, confirming that the pests have been neutralized. Additionally, monitoring gas levels is crucial; once they drop to safe levels, it indicates that the concentration necessary for effective pest control has been achieved and the area is no longer hazardous for re-entry.

While visual inspections can be useful for post-fumigation assessments, they do not provide quantitative data on pest mortality or the gas levels that are essential for confirming the efficacy of the fumigation process. Increasing pest activity would suggest the opposite of successful treatment and is therefore not an indicator of completion. Changes in weather conditions can impact the environment but are not direct indicators of whether fumigation has achieved its goal of pest control.
