How should a bellow duster be held during application?

Holding a bellow duster with the spout at the top is the correct method for several reasons related to the effective application of pesticides or dusts. When the spout is positioned upwards, it allows the operator to properly fill the duster without the risk of spilling or clogging the device. This positioning also enables a more controlled and uniform distribution of the dust or pesticide as it is released from the duster.

Additionally, having the spout at the top minimizes the risk of the product settling within the duster itself, ensuring an even flow of the material when it’s dispensed. This is particularly important in pest control applications where even coverage is essential for effective treatment. When the duster is used in this manner, it supports both the accuracy of the application and the safety of the operator by preventing direct contact with the chemical being applied.

In contrast, other positions such as spout facing sideways or downward can lead to uneven application or may hinder the operator's control over the dust release, reducing the effectiveness of the pest management treatment.
