How should you minimize termiticide from running down slope trenches?

Minimizing termiticide from running down slope trenches is crucial for effective pest control and environmental safety. Stepping the trench is an effective method because it creates a series of flat or level areas along the slope, which helps slow down the movement of the termiticide. When the trench is stepped, the composition of the soil allows for better absorption of the termiticide, reducing the risk of it washing away before it has the chance to bond with the targeted areas.

In contrast, building extension barriers might not address the slope directly, and simply applying during dry conditions may not prevent runoff if the trench design is not conducive to retaining the chemical. Increasing application volume could lead to more excessive runoff rather than containment within the trench system. Hence, stepping the trench stands out as the optimal strategy for minimizing the migration of termiticides in sloped environments.
