It does so by emitting a sonic pulse and vibration through the ground to deter their presence. Suitable for your garden, yard, farm and orchard, the snake repeller works 24/7 and up to six months with good quality batteries (not included).
Easy to set up and use. Produce a good sound and when operating I believe they are effective. However, 4 additional D cell batteries to power each repeller makes it somewhat expensive. I have also had two of the 6 purchased fail since installing them. There may be a waterproof or electronic issue. However, all my previous solar repellers have generally only lasted one season due to water ingress or battery failure and so these D cell battery powered repellers appear more resilient.
