What is the main reason to use a dust formulation for pesticides?

Using a dust formulation for pesticides primarily enables effective application in areas that liquid pesticides may not be able to reach. Dust formulations have a unique ability to adhere to surfaces and penetrate into hard-to-access locations, such as cracks, crevices, and voids, where pests often reside. This precision is vital for targeting pests in their hiding spots, ensuring that the pesticide reaches the intended target more effectively.

Dusts can remain in place longer compared to liquids, which may run off or evaporate. This prolonged presence can provide ongoing control of pests, especially in environments where moisture could affect other formulations. The physical properties of dust allow it to disperse in the air, increasing its coverage area, thereby enhancing its efficacy against various pests compared to liquid formulations when dealing with inaccessible areas.

While other options may present certain advantages, such as cost-effectiveness or lower usage rates, the distinctive benefit of reaching areas that liquids cannot is the primary reason for choosing dust formulations in pest management.
