Quick Answer
Bird spikes are generally non-toxic and non-lethal, making them a humane option for deterring birds from nesting on solar panels. However, improper installation can increase the risk of harm to birds. Effective installation techniques minimize this risk.
Choosing the Right Bird Spikes
When selecting bird spikes, consider the size and material of the spikes. Plastic or metal spikes with a diameter of 1-2 mm are effective at deterring birds without causing harm. For example, the Bird-B-Gone Spike Strip is a popular option made from plastic with a diameter of 1.5 mm.
Installing Bird Spikes Safely
To minimize the risk of harm to birds, install spikes at an angle of 20-30 degrees, with the spikes pointing downwards. This angle helps prevent birds from getting their feet or beaks entangled in the spikes. Install the spikes at a height of 2-3 feet above the ground to reduce the risk of birds nesting on the solar panels.
Additional Deterrent Measures
While bird spikes are effective, they may not be enough to deter all birds. Additional measures such as visual deterrents, like owls or hawks, or noise-making devices, like ultrasonic bird repellers, can be used in conjunction with bird spikes to provide a more comprehensive bird control solution.
