ABOUT US

We were founded on December 5, 1983, by the San Bernardino County Board of Supervisors after a group of citizens pushed to form a Mosquito Abatement District.

The District serves over 650,000 people residing in 6 cities: Chino, Chino Hills, Montclair, Ontario, Rancho Cucamonga, Upland, and surrounding county areas. 

Each city has an appointed person serving on the Board of Trustees while the county areas we serve have an at-large representative.  If you live within our service area, feel free to call us or fill out a service request online for any vector issues. We are here to assist you in any way we can.

We are a Special District dedicated to protecting public health. For more information on California Special Districts, visit districtsmakethedifference.org
