What is the maximum time before a pesticide application that sensitive persons must be notified?

The maximum time before a pesticide application that sensitive persons must be notified is 24 hours. This requirement serves to ensure that individuals who may be particularly vulnerable to pesticide exposure, such as those with respiratory issues, allergies, or other health concerns, are given adequate warning. It allows them sufficient time to make necessary preparations to avoid exposure, such as leaving the area or taking other precautions. Proper notification is a critical component of responsible pesticide use and helps to mitigate risks to human health, especially for those who may be at higher risk.
