Albuquerque, NM (KKOB) — Rancid animal fat may be the key to keeping those pesky mosquitos at bay. A research team at NMSU has found that rancid fats from animals, including bears and pigs, are effective when it comes to keeping some insects away. The research based on historical evidence that Native Americans used the substance to protect themselves against mosquitoes. Aware that most people would be appalled at the idea of slathering themselves with stinky grease, they’re examining which molecules actually repels bugs. They’ll then use that information to develop an insect repellent that works without being so smelly.
