Just turn on the radio, and the mosquitoes fly away / GO OUTSIDE MAGAZINE "REPELLENT RADIO"

A radio station in São Paulo secretly mixed a 15kHz tone into its music programming from 6 to 8pm. Humans can't hear it. But mosquitoes can. Since it mimics the sound of a dragonfly's wings—a mosquito's natural predator—the mosquitoes flee. Just by having the radio on, you get bug protection.
