"CO2 emitted in human breath is the main attractant for the Culex mosquito to find people, aiding the transmission of these deadly diseases," Ray said. "In our experiments we identified hexanol, and a related odor, butanal, as strong inhibitors of CO2-sensitive neurons in Culex mosquitoes. These compounds can now be used to guide research in developing novel repellents and masking agents that are economical and environmentally safe methods to block mosquitoes' ability to detect CO2 in our breath, thereby dramatically reducing mosquito-human contact."
Woah, this is just great! This should be a great reason to celebrate, once thei're done with the repellent. I think there isn't one person in the planet who hasn't got mad with mosquitos at one time or another.

Great news, just great.
