Fight the Bite!


Mosquitoes are one of the deadliest creatures on earth; they have the potential to spread many different viruses like West Nile, dengue, chikungunya, and even Zika. There are over 3000 different species of mosquitoes in the world; 26 of these species are found in the County, some of which are potential spreaders of these viruses (called “vectors”). The Vector Control Program monitors, tests, and controls mosquitoes and provides education and outreach. In order to keep yourself, family and neighbors safe from mosquito borne diseases, follow these three simple steps: Prevent, Protect and Report!

Prevent mosquito breeding around your home.

Protect against mosquito bites by using mosquito repellents and wearing long sleeves and pants.

Report mosquito breeding sites like green swimming pools and other standing water in your neighborhood
