What is the primary purpose of Dust formulations?

The primary purpose of dust formulations is to combine insecticides with a dust diluent. Dust formulations consist of finely ground particles that can include active ingredients, such as insecticides, and carriers that help distribute the active ingredient effectively. By incorporating a diluent, the formulation ensures that the insecticide can be applied evenly and effectively across surfaces where pests are present.

This method enhances the product's adherence to surfaces, promotes longer-lasting efficacy, and provides a mode of action that is beneficial for targeting various types of pests. The formulation allows for precise application in locations where liquid sprays may not be suitable, such as in cracks and crevices, thus improving pest control strategies.

Other options relate to different characteristics or consequences of pest control actions but do not reflect the main intention of dust formulations in their basic operation and design.
