N,N-Diethylbenzamide is widely used as an insect repellent, particularly effective against mosquitoes, ticks, and other biting insects. It is commonly applied to skin, clothing, or gear to provide protection in outdoor settings, such as camping, hiking, or working in areas with high insect activity. Its ability to disrupt the sensory receptors of insects makes it a key ingredient in many personal care products, including lotions, sprays, and wipes. Additionally, it is utilized in veterinary applications to protect livestock and pets from insect bites and related diseases. Its stability and low toxicity to humans make it a preferred choice for long-lasting insect protection.
