To affect the efficacy of the fumigants
To ensure proper disposal of chemicals
To prevent pests from returning

The correct answer is: To affect the efficacy of the fumigants

Monitoring humidity alongside fumigant concentration is critical because humidity can significantly influence the efficacy of the fumigants. The performance of many fumigants is affected by the moisture levels in the environment. Higher humidity can enhance the penetration and effectiveness of certain fumigants, ensuring they reach the pests more effectively. Fumigants often require a specific range of humidity to optimize their action, as moisture can impact both the vaporization of the fumigant and the biological activity of the target organisms. If humidity is too low, a fumigant may not disperse properly or adequately affect the pests, reducing its effectiveness. Therefore, maintaining appropriate humidity levels is essential for achieving satisfactory fumigation results and ensuring that pest control measures are effective.
