Insecticide Deet (Diethyltoluamide) 99% CAS 134-62-3 Insect Repellent

Diethyltoluamide (DEET) works by interfering with the olfactory receptors of mosquitoes. This blocks their sense of smell and prevents them from detecting human scent. Research shows that DEET can "capture" human odors. It acts like an "invisible cloak" that conceals human scent and keeps mosquitoes away from people. When DEET mixes with human odors, it reduces the number of human scent molecules in the air by 20%. This diminishes the mosquitoes' ability to perceive those scents. Additionally, DEET causes discomfort to mosquitoes, making them averse to its smell and prompting them to avoid bites.
 

Application

DEET (N,N-Diethyl-meta-toluamide) is a widely used insect repellent, primarily found in products like mosquito sprays and floral waters. It can be directly applied to the skin to repel mosquitoes effectively. The mechanism of DEET involves inhibiting the electrophysiological response of mosquitoes to key components of human sweat, such as lactic acid and 1-octen-3-ol. This action masks or blocks the mosquitoes' olfactory system, preventing them from recognizing suitable prey and thus helping to prevent bites. Additionally, DEET can be applied to the surface of clothing, providing repellent effects against various insects, including mosquitoes, ticks, fleas, mites, and leeches.
