DEET

N,N-Diethyl-meta-toluamide, also called DEET (/dt/) or diethyltoluamide, is the most common active ingredient in insect repellents. It is a slightly yellow oil intended to be applied to the skin or to clothing, and provides protection against mosquitoes, ticks, fleas, chiggers, leeches, and many other biting insects.

History

DEET was developed in 1944 by the United States Department of Agriculture for use by the United States Army, following its experience of jungle warfare during World War II. It was originally tested as a pesticide on farm fields, and entered military use in 1946 and civilian use in 1957. It was used in Vietnam and Southeast Asia.

Preparation

A slightly yellow liquid at room temperature, it can be prepared by converting m-toluic acid (3-methylbenzoic acid) to the corresponding acyl chloride, and allowing it to react with diethylamine:

Mechanism and effectiveness

DEET was historically believed to work by blocking insect olfactory receptors for 1-octen-3-ol, a volatile substance that is contained in human sweat and breath. The prevailing theory was that DEET effectively "blinds" the insect's senses so that the biting/feeding instinct is not triggered by humans or other animals which produce these chemicals. DEET does not appear to affect the insect's ability to smell carbon dioxide, as had been suspected earlier.

TATU LYRICS
"30 Minut (30 Minutes)"
Zarevet ubezhat
Ili dver na zamok
I molchat I lezhat
Izuchat potolok
I mechtat ne kad vse
Tselovat nebesa
Potolok karusel
Polchasa polchasa
Polchasa poezda pod otkos
Palchasa ne tvoya polosa
Palchasa, palchasa v ne vopros
Ne otvet polchasa, polchasa
Polchasa bez tebya, polchasa
Polchasa on I ya, polchasa
Kazhdyi sam, kazhdyi sam Polchasa
po svoim adresam Polchasa
Sorvalas I kak vse
Kak vo sne
Ya ni ya
Ne moya karusel
I mechta ne moya
Ili dym, ili grust
Ili dozhd, po glazam
Ya vernus, ya vernus
Polachasa, polchasa
Polchasa poezda pod otkos
Palchasa ne tvoya polosa
Palchasa, palchasa v ne vopros
Ne otvet polchasa, polchasa
Polchasa bez tebya, polchasa
Polchasa on I ya, polchasa
Kazhdyi sam, kazhdyi sam Polchasa
po svoim adresam
