keep an eye out for your livestock & poultry with the unique Nite Eyes Protection System Nocturnal Predators want to hunt and feed at night without being noticed. Any disruption to an ideal “attack” environment will cause them to hesitate and flee. Predators believe the Solar Nite Eyes may be a set of eyes of another creature. This causes fear of the unknown and will keep them away from your protected area. This Concept simply Works! The Solar Nite Eyes will operate maintenance free for years when used properly.
