N,N-Diethyl-m-toluamide, commonly known as DEET (CAS 134-62-3), is a highly effective insect repellent used against mosquitoes, ticks, fleas, and other biting insects that can transmit diseases such as malaria, Lyme disease, and Zika virus. DEET works by disrupting insects' sensory systems, preventing them from detecting and landing on treated surfaces.
Available in various formulations including sprays, lotions, gels, and wipes, DEET products offer flexible application options. Higher concentrations provide longer-lasting protection, making DEET essential for outdoor activities, travel, and professional use in insect-prone areas.
As a key component in public health initiatives, DEET plays a vital role in disease prevention programs. When used according to guidelines, it has an excellent safety profile while effectively reducing the risk of insect-borne illnesses.

DEET primarily functions as an insect repellent by interfering with insects' olfactory receptors, preventing them from detecting human chemical cues like carbon dioxide and body odor. This non-toxic repellent provides protection without killing insects, making it safe for skin and clothing application in various settings.
