Motion-activated bird repellers are ideal for use in small areas like backyards, patios and balconies where birds and small animals are a nuisance. Electronic repellers are activated when the motion sensor detects movement anywhere in the "coverage zone".
Motion-activated bird repellers use "always on" technology meaning the device is ready to activate and frighten away pests instantly. Motion-activated bird repellers and animal repellers are easy to set-up and require very little maintenance once the device is installed.
These devices are an economical and humane bird control solution. Consider using multiple units to expand protection against pests.
