What is the main disadvantage of using granules for pest control?

Using granules for pest control can indeed pose the main disadvantage of potentially not reaching all areas where pests may be present. Granules are solid particles, and their effectiveness can be influenced by the way they are distributed in the environment. Unlike liquid formulations, which can easily penetrate into cracks and crevices where pests often hide, granules may only be effective in areas where they are applied directly.

The distribution of granules can also be affected by environmental factors such as wind, rain, and the terrain of the application site. If the granules do not make contact with the target pest, their efficacy is diminished. This limitation can lead to uneven pest control results, making it challenging to ensure that all areas are treated adequately.

In contrast to the other options, granules are generally not difficult to apply, as they often come in easy-to-use formulations for broadcasting. They do not usually require mixing with water, which can save time during application. While there is ongoing debate about the effectiveness of different formulations, this does not inherently make granules less effective overall; their effectiveness largely depends on the specific pest, application technique, and environmental factors.
