When using a bellows hand duster, where should the stem be positioned?

When using a bellows hand duster, positioning the stem at the top is essential for effective operation. This orientation allows for the best airflow and distribution of the insecticide or pesticide being applied. When the stem is positioned at the top, it ensures that as the bellows are squeezed, the material can easily flow downwards into the application area, promoting an even and controlled release of the dust.

This top position also helps prevent clogging, which can occur if the duster is used improperly. Maintaining this configuration ensures that the operator can accurately deploy dust into cracks, crevices, and other targeted areas where pests may reside, enhancing the overall efficacy of the treatment. Understanding the mechanics of how the bellows and stem function together in this manner is crucial for anyone working in pest management.
