How does deet repel mosquitos? ...

Can anyone identify this rose?
Answers:    DEET works by corrupting receptors on the mosquito¡¯s antennae. A blood seeking mosquito hones in on you by detecting three things: 1) your body warmness, 2) the carbon dioxide you exhale, and 3) a variety of chemicals your body excretes on your skin, the most vital of which is lactic acid. Some receptors on a womanly mosquito¡¯s antennae are tuned to this lactic acid and nought else. DEET turns off those receptors, so the nerves connected to them simply don¡¯t fire. The shutdown of the lactic sharp receptors by DEET blinds the female mosquito to our presence regardless of the carbon dioxide and the moist warmness from our body.
When the female mosquito flies into areas where on earth lactic acid is detected, she go immediately into alive hunting mode. When DEET is in the heavens, she flies erratically apparently searching for some scent of a target, unconscious that one is nearby.

Mosquitoes hold an instinct for finding food sources, animals and people, base on what chemicals they emit, or what they smell close to. Deet interferes with this by putting out a chemical that blocks a mosquito from mortal able to identify you as a food source.
