One way to repel mosquitoes but to use mosquito coil, or anti-mosquito lotion is to use the application to repel mosquitoes and rats. This application will generate ultrasonic sound in the PC internal speaker with a frequency of 20000Hz-65000Hz that will interfere with nerve mosquitoes, ants, flies, rats and cockroaches. But do not bother humans because the ultrasonic sound is not audible.
