Widely use :Just insert the mole stake into a sunny place like lawns, yards and gardens. 6 different sound wave pulses, 6 are fired randomly so that the mole will not get used to it. (For example, 2 seconds on, 10 seconds off, then 3 seconds on, 20 seconds off, then 4 seconds on, 60 seonds off, it works randomly, not in sequence).
