Why is the understanding of exposure routes important in pest management?

The understanding of exposure routes is critically important in pest management because it helps in selecting the right pesticides for a task. Different pests may be susceptible to various chemicals depending on how they come into contact with them—whether through ingestion, inhalation, or dermal contact. By understanding these routes, pest management professionals can choose the most effective pesticide formulations, application methods, and timing that align with how the particular pest species is likely to encounter the treatment. This targeted approach enhances efficacy and minimizes unintended exposure to humans, pets, and non-target organisms, ultimately leading to more successful pest management outcomes.

Identifying effective traps, determining service costs, or influencing pest population growth are secondary aspects that may be considered in a comprehensive pest management strategy, but they do not directly address the critical role that exposure routes play in pesticide selection.
