What is the order of treatment methods from least to most potential exposure?

The correct order of treatment methods from least to most potential exposure is identified as crack and crevice, spot, and then general treatment.

Crack and crevice treatments are designed to target pests in specific, high-use areas with minimal exposure to humans and non-target organisms, thus offering low potential exposure. This method focuses on applying pest control substances into cracks and crevices where pests are likely to hide, which effectively limits dispersal and mitigates risk.

Following this, spot treatments involve applying pest control products to specific areas where pests are detected, leading to a slightly higher potential exposure since these applications may cover more surface area than crack and crevice methods, although they still focus on targeted locations rather than widespread dispersal.

General treatments, on the other hand, are broad applications over larger areas and generally come with a higher potential exposure since they can influence a wider range of species and areas, including unintended targets and environments.

Understanding these differences in treatment methods is crucial for effectively managing pest control while minimizing risks to human health and the environment.
