Integrated Vector Management

The District’s mission is to protect the public health by using scientifically-driven integrated vector management techniques (IVM). IVM is a rational decision-making process which seeks to improve the efficacy, cost-effectiveness, ecological soundness and sustainability of disease-vector control. The ultimate goal is to prevent the transmission of vector-borne diseases.

Components of IVM

  • Surveillance and Quality Control
  • Physical Control
  • Biological Control
  • Microbial & Chemical Control
  • Public Outreach

Surveillance and Quality Control is carried out by monitoring mosquito activity, mosquito populations, climate change and virus activity by having mosquitoes tested for arboviruses. This information is utilized to guide all control efforts. The District’s Quality Control Program develops, evaluates, and encourages compliance with best management practices.

  • Survey adult mosquitoes and arbovirus
    • Produce information on abundance levels
    • Detect presence of mosquito-borne virus
    • Determine risk levels, act, and educate
  • Evaluate the impact of control products
    • Examine resistance to control products
    • Examine rates and application methods
    • Ensure that applications are effective

Physical Control is achieved by manipulating the environment to reduce mosquito breeding sites. This can be done by:

  • Making the habitat unattractive to the pest
  • Promoting effective water drainage
  • Controlling vegetation
  • Changing irrigation patterns
  • Removing standing water
  • Encouraging best management practices in urban, agricultural and conservation areas

Biological Control is the use of an animal or pathogen (living organisms) to control a particular pest.

  • Mosquitofish (Gambusia affinis) can quickly adapt, multiply and are capable of sustaining an effective control level.

Microbial & Chemical Control is the use of chemical compounds (insecticides) to reduce mosquito populations. These methods are used when other methods are unable to maintain mosquito numbers below a tolerable level, or to terminate the transmission of disease to humans or animals. Products used are very low in toxicity and are species specific.

Public Outreach informs Coachella Valley residents about District services, health threats, and protection and prevention tips by disseminating information through media outlets, community events, and community presentations. Efforts also encourage behavior change including preventing mosquito breeding.

The District offers school presentations to students from preschool through post-secondary classes. Presentations focus on vectors, their biology and habitats, and the diseases they transmit. Students learn the various methods used to help control vector populations. There is no fee for these presentations.
