Which application method is commonly used for applying dusts to indoor environments?

The method that is commonly used for applying dusts to indoor environments is compressed air dusters. This application technique is effective because it allows for a precise and even distribution of dust formulations in areas that may be difficult to reach with other methods. Compressed air dusters can propel the dust into cracks, crevices, and other nooks where pests may reside, ensuring thorough coverage.

Dust applications are particularly advantageous indoors since they can adhere to surfaces and remain effective for longer periods compared to other formulations. This method minimizes the risk of over-application and reduces the chance of pest resistance development, making compressed air dusters a preferred choice in many pest management scenarios.

While other methods like granule applicators, liquid pesticide applications, and roller pumps serve important purposes, they do not offer the same level of effectiveness in applying dust formulations within indoor spaces. Granule applicators are typically used for solid formulations, liquids can lead to potential runoff and are better suited for outdoor applications, and roller pumps are designed for liquid dispersions rather than dust.
