Alameda County Mosquito Abatement District

Alameda County Mosquito Abatement District Alameda County Mosquito Abatement District has been protecting public health by reducing mosquito populations in Alameda County since 1930.

It is the overall goal of the Alameda County Mosquito Abatement District to provide for the public's health and comfort by carrying on a program of mosquito control and source reduction which is responsive to the public, is cost effective, compatible with the environment, and consistent with land use planning or zoning. This goal is met by the implementation of programs to:

Eliminate existing mosquito sources (Source Reduction). Educate land owners to manage potential mosquito sources effectively and thereby reduce mosquito numbers to an acceptable level. Apply safe and environmentally-sound larvicides to aquatic sources to prevent the emergence of unacceptable levels of pest and vector mosquitoes.
