"Fight the Bite"

Tucson Water is a partner in “Fight the Bite!” to help protect residents from the West Nile Virus, which is transmitted by mosquitoes.

West Nile Virus is transmitted to animals and humans through the bite of a mosquito who has previously bitten a West Nile Virus-infected bird. The best way to avoid contracting this disease is to prevent mosquitoes from breeding and biting.

  • 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.
  • Check the screening on windows and doors for holes.
  • Check your yard. Pour out or remove any standing water. Change water every other day in bird baths and pet water dishes.

Tucson Water’s Effort to Prevent Mosquito Breeding

Weekly monitoring of adult mosquito populations, weekly application of larvicide, and twice-weekly night adulticide fogging takes place at Sweetwater Wetlands. Monthly monitoring of adult mosquito populations takes place at CAVSARP and SAVSARP in Avra Valley.

The Pima County Health Department (PCHD) is the lead agency for this region. Visit their West Nile Virus web page for information on joining the fight against mosquitoes. The PCHD Mosquito Study Map has current information on mosquito surveillance.
