Vector Control

Riverside County offers an abundance of recreational opportunities including hiking, bicycling, and camping in the cities, mountains and foothills, which result in large numbers of people risking possible exposure to diseases vectored by animals and insects in these areas. Some examples of these organisms and some of the pathogens they can carry are:

  •   Mosquitos - West Nile Virus, St. Louis Encephalitis, Western Equine Encephalitis
  •   Rodents - Hantavirus
  •   Rodent Fleas - Plague
  •   Western Black Legged Ticks - Lyme Disease

The mission of the Vector Control Program is to foster a healthy community by protecting the residents of Riverside County from animals and insects that transmit pathogens that cause illness. Vector Control personnel also respond to complaints throughout the unincorporated areas of the County and in cities with contracts to provide identification, consultation, and abatement services. With the population growth in Riverside County, there are increasing demands for the services this Program has to offer.

Poultry Ranches

The maintenance of sanitary conditions on poultry ranches is essential in the control of synanthropic flies, mosquitoes, and commensal rodents.  To insure sanitary conditions and compliance with state and local requirements, bimonthly inspections are conducted on 17 poultry ranches located in the western portion of Riverside County.  Our Environmental Health Technicians comply with very strict bio-security measures due to past quarantines such as Exotic New Castle Disease and the potential threat of Avian Influenza.
