Laser Bird Deterrent Light is based on Laser beam Technology which repel birds during lighting conditions of 10.000 Lux or less, which can be compared with cloudy weather. Birds perceive the laser beam as an approaching physical danger and fly away in search for safer grounds. Unlike conventional methods of bird deterrence, there will be no habituation effect. After consistent use, birds will perceive the area as unsafe and will not return. Laser Bird Deterrent Light is most effective during sunrise and sunset and in overcast, rainy or foggy weather conditions.
