Our state of the art solar powered ultrasonic waves repellent system effectively prevent pests from damaging your land by becoming permanent guests on your lawn, farm or garden. When placed in the ground and activated, sonic pulses penetrate the soil every 30 seconds, emitting a sound which is highly irritating to moles and gophers, mice, voles, snake and other rodents. Keep your garden, yard or farm free from rodents and pests! Our 4 piece upgraded repellents are hardware and are equipped with a sensor that gives off a vibrating pulse that acts as a remover for pests. This is a great premium choice and is an excellent choice to safeguard your lawn and camping. You do not need expensive traps. Because these underground rodents are virtually blind they are exceptionally sensitive to sound and vibrations. Effectiveness of the product depends largely upon soil type. Moist clay is the best conductor of sound; dry, sandy or peat soil does not conduct the sonic waves as easily.
