N,N-Diethyl-m-toluamide, commonly referred to as DEET and listed under CAS number 134-62-3, is a widely used chemical compound known for its potent insect-repelling properties. This substance is a key ingredient in many insect repellent products designed to protect against mosquitoes, ticks, fleas, and other biting insects.
DEET functions by interfering with the sensory mechanisms insects use to locate humans, effectively masking the chemical signals that attract them. Available in various forms such as sprays, lotions, and wipes, DEET is used to treat skin, clothing, and outdoor gear, providing comprehensive protection in environments where insect bites are a concern.
It is especially valuable in preventing bites that can lead to serious diseases like malaria, dengue fever, and Lyme disease. DEET is also widely employed in military and occupational settings to safeguard individuals in high-risk areas. Public health programs often distribute DEET-containing products to mitigate the spread of insect-borne illnesses.
