Mice and insects don't "like" loud sounds especially above 20kHz or 40kHz. Humans are not able to hear that frequencies. So, this circuit is standard oscillator with NE555 and piezo speaker. If you add amplifier stage on output, you could get even more peace from bugs and mices. Real frequency should be obtain with a litlle experiments, but anything above 30kHz should work.
