Integrated Vector Management Program


The Vector Control Program (VCP) is a countywide program, managed by the County of San Diego Department of Environmental Health and Quality (DEHQ), that implements Integrated Vector Management activities to protect public health from the impacts of vector-borne diseases. These activities reduce the potential for the spread of diseases and the impact that vectors have on property and include ongoing educational outreach, vector surveillance activities, source reduction (i.e., physical control), and source treatment (i.e., biological and chemical control). The VCP’s core services include:

  • Early detection of public health risks through comprehensive vector surveillance and testing; 
  • Control and reduction of vectors that transmit diseases to humans; 
  • Dissemination of vector-borne disease information to provide county residents and property owners with tools for prevention, protection, and reporting of vectors that transmit diseases; 
  • Appropriate and timely response to vector-related customer complaints; 
  • Detection of vector-borne pathogens.

Environmental Review

As a program of the County DEHQ, Vector Control staff are responsible for implementing the IVMP. County DEHQ is the lead agency in the preparation of a Program Environmental Impact Report (PEIR) for the IVMP (Proposed Project). The PEIR is intended to allow the County to examine the overall effects of the implementation of the Proposed Project and to take steps to avoid environmental impacts.

The Proposed Project will also allow for inclusion of progressive and emerging vector control activities and materials. New vector control methods based on scientific evidence and expert guidance may be implemented to address public health risks as they arise. These emerging vector control strategies could include increased or advanced/early source prevention, reduction, surveillance and/or physical/biological/chemical control, depending on the assessment of public health risk.

Pursuant to the California Environmental Quality Act (CEQA), the County DEHQ prepared the following Notice of Preparation and Initial Study for public review and held a public scoping meeting on August 30th, 2018.
