PEST MANAGEMENT THRESHOLDS
The IPM must clearly identify the threshold that requires action by the IPM team. Determining the action threshold will be an important aspect of the IPM. For many pests, the threshold may be low. Bed bugs, for example, are difficult to manage once there is an infestation, and require immediate action to address the pests. Similarly, rats can resist multiple extermination attempts and should have a very low action threshold to manage an infestation.
The action thresholds may vary over time. Provide flexibility in the IPM to address modifications to the action thresholds. This is critical in maintaining a pest-free environment.
Along with modifications from the IPM team, the process must include the integration of occupant reports of observed infestations or increased pest activity. Clearly identify the process for modifying action thresholds, including informed occupant reports and IPM team observations.
PEST CONTROL METHODS
Pests can cause property damage, spread diseases, and contaminate food sources. Therefore, it is critical to implement pest control methods immediately after exceeding the action threshold. For each identified pest, describe all possible control methods. In all cases, give preference to the lowest-risk option.
When determining the lowest-risk option, considerations should include the building occupant’s health, the natural environment, and the risk to the applicator. Considerations for small applications of pesticides may control the population and have limited risk to the applicator, the occupants, and the environment.
NONCHEMICAL PEST PREVENTATIVE MEASURES
Nonchemical pest control measures rely on plants, herbs, natural elements, and the use of natural predators as methods of pest control. Companion planting nurtures a balanced environment and keeps many invasive pest populations away from a building or site. Providing habitats for pest predators, like owls and birds, can also naturally control pest infestations.
Additional measures, like closing gaps in the building envelope, moisture control, and protecting finishes on exposed wood, provide effective methods of control. For nonchemical measures, like the use of traps, detail the requirements for effective management within the IPM plan.
IDENTIFICATION OF LEAST-RISK PESTICIDES
Wherever possible, apply the least-risk pesticide or preventative measure. Project teams may use the San Francisco Pesticide Hazard Screening Protocol to classify the hazardous level of a
