+Pest management objectives, including protocols for identification of pests and metrics of progress.
+Design and operational measures to prevent conditions that may attract pests.
+Pest tolerance thresholds and control strategies (including methods and response times) for when tolerance thresholds are exceeded, attending to the safety of the applicator, the occupants and the environment.
+Records of pest monitoring data, pest events, pesticide applications, control actions and emergency responses.

+Each pesticide used for periodic (i.e., non-emergency) application is listed in the plan and meets one of the following:
Evaluated through the City of San Francisco Pesticide Hazard Screening Protocol with a Hazard Tier ranking of 3 (least hazardous).

Listed in the most recent version of the City of San Francisco’s Reduced Risk Pesticide List as directed in the list (including limitations).
