What is a characteristic of granular pesticides compared to liquid sprays for foundation treatments?

Granular pesticides are designed to be effective in specific ways, particularly in foundation treatments. One of their key characteristics is how they interact with the environment they are applied to. Granular formulations consist of larger particles than liquid sprays, which allows them to settle into the ground and integrate effectively with the soil and surrounding materials, such as mulch and leaf litter.

This characteristic of providing better penetration through these materials is beneficial for targeting pests that may reside in those layers. The larger granule size also helps prevent runoff and ensures that the pesticides remain in place longer, allowing for a sustained action against target pests.

In contrast, liquid sprays can more easily wash away or be affected by environmental factors, leading to potential drift or evaporation. The physical properties of granules allow them to maintain their placement and effectiveness even in the presence of debris on the surface, making them particularly useful for foundation treatments where the presence of mulch or plants may obscure the area being treated.
