About Vector Management Program

Vectors, such as rats, mice, and other vermin are known to cause human disease. It is important that proper sanitation is maintained at properties throughout Los Angeles County to eliminate food sources and harborage conditions that can help these vectors to grow and thrive.

The objective of the Vector Management Program is the reduction of the risks of exposure to the pathogens of vector-borne disease through early detection and abatement of those conditions that enhance the transmission of disease to humans. This program consists of two parts, Vector-borne Disease Surveillance and Vector Control.

The Vector-borne Disease Surveillance team conducts routine surveillance of such diseases as plague, flea-borne or murine typhus, Lyme borreliosis, as well as hantaviruses and arenaviruses.

The Vector Control team is responsible for investigating rodent complaints and conducting inspections of licensed animal keeper premises for sanitation concerns in most areas of Los Angeles County.
