Featuring an innovative M-shaped design, our latest bird spikes can be easily installed in places where standard bird spikes cannot fit. They securely attach to eaves, fences, and walls with ease. Made with UV-resistant and weatherproof materials, these spikes are built to last in various environments. Each spike measures 30cm (11.81 inches) in length, 5cm (1.97 inches) in width, and 7cm (2.75 inches) in height. Designed to deter birds and other animals humanely, the spikes use varying heights and the unique M-shape to prevent perching without causing harm. This smart design takes advantage of birds' natural instincts, helping to prevent excessive droppings and messy nesting. Easy to install with no complicated steps required. Each box includes cable ties and screws for straightforward fixing. You can also use adhesive or other tools for additional support.
