What is DEET?

It is a widely used pesticide. Spray on skin or clothes to avoid insect and mosquito bites. It contains human sweat and respiration, and works by blocking the 1- octene -3- alcohol of insect olfactory receptor. The popular theory is that DEET effectively makes insects lose the feeling of emitting special odor to humans or animals.

At room temperature, DEET is a colorless or yellowish liquid. It can be made of diethyl and methylbenzoic acid. It can also be made of acyl chloride and ethylamine. Therefore, the ability of mosquitoes to find targets through their special sense of smell can be largely ruled out, not completely ruled out.

DEET is volatile and contains human sweat and breath. It works by blocking 1 octene -3- ol of insect olfactory receptor. The popular theory is that DEET effectively makes insects lose the feeling of emitting special odor to humans or animals. As people initially suspected, DEET did not affect the ability of insects to smell carbon dioxide.

However, recent scientific research shows that DEET, as a real mosquito repellent, works by making mosquitoes feel uncomfortable. Mosquitoes with antenna receptors of type A olfactory receptor neurons have been proved to have obvious response to the effect of DEET, and there are other known mosquito repellents, such as cineole, linalool and jasmonate.
