“Integrated pest management” is defined as a pest management system that includes the following elements:
         (a) identifying pests and their natural enemies;
         (b) establishing an ongoing monitoring and
    
recordkeeping system for regular sampling and assessment of pest and natural enemy populations;
        (c) determining the pest population levels that can
    
be tolerated based on aesthetic, economic, and health concerns, and setting action thresholds where pest populations or environmental conditions warrant remedial action;
        (d) the prevention of pest problems through improved
    
sanitation, management of waste, addition of physical barriers, and the modification of habitats that attract or harbor pests;
        (e) reliance to the greatest extent possible on
    
nontoxic, biological, cultural or mechanical pest management methods, or on the use of natural control agents;
        (f) when necessary, the use of chemical pesticides,
    
with preference for products that are the least harmful to human health and the environment; and
        (g) recordkeeping and reporting of pest populations,
    
surveillance techniques, and remedial actions taken.
