What is the appropriate pressure for crack and crevice treatments of pesticides?

The appropriate pressure for crack and crevice treatments of pesticides is in the range of 5-10 psi. This pressure level is specifically designed to allow for effective application without causing excessive spray drift or oversaturation. When using this pressure range, the pesticide can penetrate the targeted areas, such as small gaps, cracks, and crevices, where pests are likely to hide, while still adhering to the safety guidelines that prevent harm to non-target areas and organisms.

Applying pesticides at pressures higher than 10 psi can lead to a misting effect or drift, which not only reduces the efficacy of the treatment but also poses risks to surrounding environments and ecosystems. Conversely, pressures lower than 5 psi may not provide adequate penetration or coverage in the intended treatment areas. Hence, the 5-10 psi range balances effectiveness with safety, making it the recommended standard for crack and crevice treatments.
