"Fight the Bite"

Tucson Water is a partner in “Fight the Bite!” to help protect residents from West Nile Virus (WNV) and Zika. Both can be transmitted to humans through bites of infected mosquitoes. 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 or Zika 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.
