Now you can protect yourself, your family and your pets from dangerous snakes with this Sonic Snake Repeller! Simply stake in the ground and it’ll repel all species of snakes by emitting a sonic pulse through the ground... The snake will feel the vibration and perceive the area to be dangerous, encouraging it to turn away and leave your property. For full coverage of your yard, place repellers about 25-30 metres apart. Measures: 34.5cm H x 15.5cm W.
