Which formulation is most often used for long-term pest control?

Granular formulations are most often used for long-term pest control due to their unique properties and application methods. These formulations consist of pesticide particles that are combined with an inert substance, creating small, solid granules that can be spread on the ground.

The key benefit of granular formulations lies in their slow-release nature. They can gradually dissolve over time when exposed to moisture, allowing for prolonged exposure to the active ingredient for pests in the area where they are applied. This slow breakdown helps manage pest populations over an extended period without the need for frequent reapplication, making them particularly effective for controlling pests in soil, lawns, and gardens.

Additionally, granular formulations are often easier to handle and apply compared to other types of formulations. They present a lower risk of drift and are less likely to be washed away by rain, increasing their effectiveness in various environmental conditions. This makes them suitable for long-term pest control strategies.

In contrast, aerosols provide immediate knockdown of pests but have a shorter residual effect. Dust formulations are effective in specific situations but can also have a less lasting impact. Wettable powders require dilution and can be effective for various applications, but they may require more frequent applications to maintain efficacy.
