The Pestrol Scary Eyes Bird Scarer is bright orange and made from heavy duty rubber. (Unlike the older beach ball type that was unfortunately prone to puncture ,and deflated quickly in outside conditions)
The large orange bird scarer works by replicating a predator. Large, holographic, scary eyes; big claws and a wide open mouth all combine to help in repelling pest birds.
For larger locations we have found that as few as 4 per acre is effective. You can also attach the Scary Eyes balloon to the end of a long pole.
