The correct choice is based on the characteristics of dust formulations in pest control. Dust pesticides are composed of very fine particles that can easily adhere to surfaces, including the outer surfaces of coarse particles of dry inert substances. This adherence allows for effective coverage and delivery to targeted pests, as dust can penetrate into cracks and crevices where insects may reside.

Dust formulations often consist of active ingredients combined with inert carriers that create a low-density product. When applied, they can remain effective for an extended period, as the active ingredient is released gradually and can impact pests that come into contact with it.

In contrast, granules are larger, pellet-like particles that are typically used for applications where a slow release of the active ingredient is desired, and they do not have the same adherence properties as dust. Wettable powders are formulated to be suspended in liquid and then applied, which is different from the characteristics of a dry dust. Fumigants are gaseous pesticides that are used to penetrate structures and are not related to particulate adherence. Each formulation serves a specific purpose and is chosen based on the pest management situation at hand.
