• 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.

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.
