Mosquito Quick Facts
  • Over 3,500 species of mosquitoes in the world, 53 in California, 13 in the Coachella Valley.
  • Only females take a blood meal; they need blood protein to develop their eggs.
  • Mosquitoes use exhaled carbon dioxide, body odor, temperature and movement to target humans, other mammals and birds.
  • Females can lay 100-300 eggs per bloodmeal. 
  • Mosquito-borne diseases kill more people than any other single disease factor.
The mosquito is a highly effective and deadly vector for human disease agents. The tiny insect has played a powerful role in spreading viruses such as West Nile, St. Louis encephalitis, western equine encephalitis, dengue, and Zika.

In the Coachella Valley, we regularly detect 13 mosquito species. The species of greatest public health concern in the valley are the Culex tarsalis, Culex quinquefasciatus and the Aedes aegypti. These species are capable of transmitting micro organisms that cause disease in people.
