What is a key characteristic of a pesticide dust?

A key characteristic of pesticide dust is that it comes ready-to-use and is very fine and dry. This form allows for easy application, as it does not require any mixing with water or other solvents. The fine particles can effectively adhere to surfaces, making it suitable for targeting pests in places that are difficult to reach, such as cracks and crevices.

In contrast, pesticide dusts do not typically contain high concentrations of active ingredients compared to other formulations, and they do not need to be mixed before application, which makes them convenient. Additionally, while some dusts may have residual effects, the primary defining feature remains their dry and fine composition, which contributes to the effectiveness and ease of use.
