What type of pesticide formulation is commonly used for targeting specific pests in cracks and crevices?

Dust formulations are highly effective for targeting specific pests in cracks and crevices due to their ability to penetrate narrow spaces and adhere to surfaces where pests may hide or travel. When applied, dusts create a barrier that pests come into contact with, which facilitates the delivery of the active ingredient directly to the pest.

This type of formulation is particularly useful for managing pests like ants, cockroaches, and bed bugs that often hide in tight areas that are difficult for other types of pesticides to reach. The fine particles of dust can coat the surfaces within these crevices, providing prolonged control as the dust remains effective until it is disturbed or removed.

In contrast, other formulations serve different purposes: aerosols, while convenient for light surface applications, may not provide the same level of contact with pests hiding in tight spaces. Granules are typically used for outdoor applications or in soil, while baits attract pests to ingest the active ingredient, but do not necessarily target those that are hidden in cracks and crevices. Thus, dust is particularly well-suited for the task at hand.
