What is the purpose of the Restricted Entry Interval (REI) on a pesticide label?

Explanation:
REI sets the time after a pesticide is applied during which you should not enter the treated area, or you must enter only with the required PPE. This protects workers from dangerous exposure when residues are most hazardous. The label uses this interval because toxicity and formulation drive how long a pesticide remains a risk to people. It’s not about environmental impact, odor thresholds, or how much product is applied, which is why those ideas don’t fit.
