Los Angeles County Vector Control District is a public health service agency formed under the authority of the CA State Health & Safety Code. Their mission is to reduce populations of public health vectors below nuisance levels, prevent human infection associated with mosquito-transmitted diseases, and prevent the loss of property values and commercial enterprise as the result of vector occurrence and activity. A vector is any arthropod, insect, rodent or other animal of public health significance capable of harboring or transmitting the causative agents of human disease (e.g. malaria, plague) to humans. Under certain circumstances, insects or other arthropods that cause human discomfort or injury, but not disease, are sometimes referred to as vectors. For issues related to vector control, please visit the Los Angeles County Vector Control District's website or call the Los Angeles County Vector Control District at (562) 944 - 9656 for more information.
