Santa Clara County is home to at least 19 species of mosquitoes.  Mosquitoes are capable of transmitting diseases such as West Nile virus, Dengue Fever and Malaria.

The District’s battle against mosquitoes focuses primary on the use of environmentally friendly approaches to eliminate mosquitoes before they begin biting people and animals.

This approach starts with identifying the source of problem mosquitoes. Many residents are unaware that they may be raising mosquitoes in their backyard. Backyard breeding sources such as standing, stagnant water in plastic pools, buckets, old tires, etc., are identified and eliminated or removed. 

For sources such as ponds and marshes, the District uses environmentally sensitive methods such as mosquito fish or bio-rational products that specifically target the mosquito larvae or pupae before they hatch.

The District routinely conducts disease surveillance for mosquito-borne diseases such as encephalitis and West Nile virus.
