"Fight the Bite"

Tucson Water is a partner in “Fight the Bite!” to help protect residents from the West Nile Virus (WNV).

WNV is transmitted to animals and humans through bites of mosquitoes that have previously bitten West Nile Virus-infected birds. Weekly monitoring of adult mosquito populations, weekly application of larvicide, and twice-weekly night adulticide fogging take place at Sweetwater Wetlands

The best way to avoid contracting WNV is to prevent mosquitoes from breeding and biting:

  • Check your yard. Pour out or remove any standing water. Change water every other day in bird baths and pet water dishes.
  • Check the screening on windows and doors for holes.
  • Limit time outdoors from dusk until dawn. Mosquitoes are most active during these times. Wear long sleeve shirts and pants when possible.
  • Use protection. Use mosquito repellents that contain DEET, Picaridin, or Oil of Lemon Eucalyptus.

Monthly monitoring of adult mosquito populations takes place at Tucson Water's CAVSARP and SAVSARP facilities in Avra Valley.

The Pima County Health Department (PCHD) has a West Nile Virus web page for information mosquitoes and WNV prevention. The PCHD Mosquito Study Map has current information on mosquito surveillance.
