What is the primary use for Granules in pest control?

Granules are primarily used in pest control for soil treatment. This application method allows for targeted pest management where pests may reside or breed, often in the soil or near the ground. The granules can be formulated to dissolve in moisture, releasing the active ingredients that target insects in the soil, such as ants, grubs, and other subterranean pests. By using granules for soil treatment, pest control practitioners can effectively manage pest populations while minimizing the potential impact on non-target organisms and the environment.

In contrast, indoor spraying and surface spraying are typically done using liquid formulations tailored for those specific environments or surfaces. Food attraction is not a primary function of granules in pest control; while some baits may attract pests to the granules, their main purpose is to treat the soil effectively. Thus, soil treatment is the most appropriate and relevant application of granules in this context.
