Which formulation is primarily used in pest control and consists of attractive materials for target pests?

The formulation used in pest control that consists of attractive materials for target pests is a bait. Baits are specifically designed to lure pests into consuming them, often incorporating enticing substances that appeal to the target organisms. This makes baits highly effective because they not only deliver the active ingredient intended to control the pest population but also take advantage of the pest's natural feeding behavior.

In contrast, granules and pellets are typically solid formulations that may not necessarily include attractive materials; they are often used for soil application or surface treatment, and their efficacy relies more on the active ingredients they contain rather than their ability to lure pests. Aerosols are often used for applications where insecticides or other pesticides are dispersed in a fine mist but do not necessarily attract pests in the way baits do. Hence, baits stand out as the formulation tailored to attract and control target pests effectively.
