The Orange County Mosquito and Vector Control District's programs are based on scientifically planned management tactics and control strategies that reduce the abundance of vectors in a timely manner. This method is referred to as Integrated Vector Management (IVM).

IVM incorporates five basic methods:

1. Public information and education
2. Mosquito and vector surveillance
3. Biological control
4. Physical control
5. Microbial and chemical control

The approach seeks to improve the efficacy, cost-effectiveness, ecological soundness and sustainability of vector control activities. The key objectives of Integrated Vector Management include:

• The selection of proven vector control methods based on knowledge of vector biology and ecology, and disease transmission.
• Utilizing of a range of interventions, separately or in combination and often synergistically, integrating all available and effective measures, whether chemical, biological, or environmental.
• Collaborating within the health sector and with other public and private sectors that impact vector control.
• Engaging local communities and other stakeholders.
• Knowledge and compliance with public health regulatory and legislative frameworks.
• The rational use of insecticides.
