It is insoluble in water, miscible with ethanol, ether, benzene, propylene glycol, cottonseed oil, and is made of diethyl and methyl benzoic acid. DEET is volatile and contains human sweat and breath. It works by blocking the 1-octene-3-ol of insect olfactory receptors. The more popular theory is that DEET effectively makes insects lose their sense of special smell to humans or animals. Recent scientific studies have shown that DEET acts as a real mosquito repellent, which works by making mosquitoes feel uncomfortable. The mosquitoes of the antennal sensilla of type A olfactory receptor neurons have been confirmed to have a clear response to DEET. Application DEET is a broad-spectrum insect repellent. It has a repellent effect on a variety of stinging insects in various environments. It can repel stinging flies, midges, black flies, chiggers, deer flies, fleas, gnats, Horse flies, mosquitoes, sand flies, small flying insects, stable flies and ticks. It is widely used in various solid and liquid mosquito repellent products, such as insect repellent, to prevent mosquitoes.   Specification: Package:
