How does it work?
This unique repeller has been developed to scare away all kinds of snakes; it emits a pulsing vibration, which the snake picks up through sensors throughout its body. The snake perceives a danger zone causing them to evacuate the area; most snakes will retreat almost immediately.
The sense organs of snakes are uniquely different than those of mammals and other animals. Unlike mammals, which mainly rely on their sight and hearing, snakes rely primarily on their senses of smell and touch. They do not have moveable eyelids, but transparent caps called "brille" as protective eye coverings. Because of this, their eye movement is fairly limited. They also do not have an external ear, middle ear, or tympanic membrane (eardrum). Instead, they use a small ossicle (ear bone), called the "columella," to detect vibrations of sound waves conducted through the ground. They are able to pick up some sound waves conducted through the air, but only at very low frequencies. Snakes actually sense the vibration right throughout their bodies via their spine, this is termed somatic hearing, where the vibration is picked up and transferred along the spinal cords to the ear bone.
Much research has gone into developing the correct type of pulse to trigger the retreat instinct in snakes. It has been designed and produced to give years of trouble free service with no running costs. Solar powered for economy and low maintenance, built of sturdy materials to resist the elements. Its integrated high quality solar panel and power cell provides reliability to work continuously day and night, all year round even through prolonged periods of dull overcast weather.
