What should be avoided during the application of dusts in enclosed spaces?

Moisture should be avoided during the application of dusts in enclosed spaces because it can significantly affect the effectiveness of the pesticide. Many pesticide dust formulations are designed to work best in dry environments. When moisture is present, it can cause dust formulations to clump together, reducing their ability to adhere to surfaces or reach intended targets effectively. Additionally, moisture can lead to premature degradation of the active ingredients, diminishing their pesticidal properties and potentially leading to inadequate pest control.

In enclosed spaces, where air circulation may be limited, applying dusts in moist conditions can also increase the likelihood of causing harm to non-target organisms and can lead to other safety concerns, such as respiratory issues for the applicator. Thus, maintaining a dry environment during application is crucial for maximizing the effectiveness of pesticide dusts while ensuring safety.
