There are many types of mosquitoes found in Santa Clara County including Aedes, Anopheles, Culex, and Culiseta species. Many of them can cause severe health problems.
Management of mosquitoes in the county presents an ongoing challenge due to the variety of species and developmental sites. These habitats range from small backyard sources to marshes with hundreds of acres.
Control of mosquitoes includes:
- Detection and monitoring of mosquito sources
- Removal or alteration of mosquito breeding habitats.
- Application of mosquito insecticides, by ground or aerial equipment.
- Public education and outreach.
In addition to removal of breeding sources and insecticide application, mosquitofish (Gambusia affinis) are used as an environmentally friendly and extremely effective way of controlling mosquitoes.
Santa Clara Vector Control District encourages residents to maintain a mosquito-free environment by reducing standing water sites. More information is available at the bottom of this page.
Typical abatement procedures are used to gain access to properties to eliminate the source of a mosquito problem (e.g. a neglected swimming pool in the backyard). Local Vector Control Districts prefer to work with landowners and will make every effort to provide help and assistance.
However, if a landowner is unwilling or unable to eliminate a mosquito source (or other nuisance), local districts have the authority to access private property to inspect and abate the source of a problem. They also have the authority to charge a landowner a fee, and place liens upon property (Sections 2053, 2060-2067, and 2855 of the California Health and Safety Code).
