In structural pest control, a granular pesticide might be best used for control of:

Using a granular pesticide for controlling crickets in mulch around a foundation is a practical choice because granular formulations are particularly well-suited for outdoor applications where pests inhabit soil, mulch, or similar substrates. Granular pesticides can be easily spread in these areas, allowing for effective delivery of the active ingredient directly where crickets are likely to reside and multiply. The design of these products often permits them to remain effective over an extended period, especially in the moist environment of mulch, which can support pest activity.

In contrast, other scenarios provided may not be as ideal for granular pesticides. For example, boxelder bugs feeding on trees are typically best controlled through targeted sprays rather than granular applications, as these pests are located above ground in foliage. Mosquito larvae in a flooded ditch generally require treatments that can enter water effectively, such as liquid formulations, to be directly effective against these aquatic pests. Lastly, while white grubs damaging a lawn could potentially be addressed with granular formulations, they are usually better targeted with specific insecticides that are formulated for such soil-dwelling pests, and their control often requires a more tailored approach depending on the lifecycle stage of the grubs.

Overall, applying a granular pesticide effectively targets crickets in a habitat where they thrive, ensuring proper
