What type of pesticide duster is suitable for applying large amounts of dust in an attic space?

The rotary duster is well-suited for applying large amounts of dust in an attic space due to its design and functionality. This type of duster utilizes a mechanism that allows for the rapid and even distribution of dust over a wide area, making it particularly effective in larger and confined spaces like attics where thorough coverage is necessary. The ability to adjust the output and direct the airflow ensures that the dust reaches all corners, which is crucial for effective pest control in those hard-to-reach areas.

In contrast, hand-held dusters are more appropriate for smaller applications or targeted areas, as they require manual operation and may not dispense enough material for extensive coverage. A pressure sprayer is designed for liquid applications rather than dust, making it unsuitable in this context. Lastly, a seed duster is intended for planting seeds, not for pesticide application, and wouldn’t provide the necessary features for pest control. Thus, the rotary duster stands out as the most efficient option for the task at hand.
