- Effective Squirrel Deterrent: Our dual-layer system features a 19" squirrel deflector and 40" spikes to block climbing and jumping. The ultra-smooth, slanted design prevents squirrels from gaining a claw grip, while the spikes effectively stop them from leaping over. This ensures your bird feeder remains safe, allowing birds to enjoy seeds without interference. - Versatile Usage: This squirrel-proof bird feeder offers dual mounting options. It can be pole-mounted (compatible with 1/4" to 1.5" diameter feeders) with wraparound spikes to deter raccoons and squirrels. Alternatively, it can be hung as a pendant light using the included S-hooks, with spikes to protect against chipmunks and snakes. - Durable Construction: Made from industrial-grade ABS plastic, this bird feeder is rustproof and chew-resistant, outperforming metal and other plastic alternatives. It withstands extreme weather conditions without cracking or fading. The glazed finish allows for easy cleaning with just a hose. - Humane Deterrent: Equipped with 3.04 stainless steel spikes, our system offers a non-lethal approach to rodent deterrence, ensuring a humane solution to keep unwanted visitors away. - Simple Installation: Assembling the bird feeder is straightforward; simply press the button on the side—no tools required. The included baffle bracket and 3M spacers accommodate thinner feeders, enhancing stability. Additional cable ties, wires, and screws make securing the spikes easy in various settings. - Optimal Protection: For maximum effectiveness, install the feeder at least 2.4 meters away from trees or platforms and position it at a height of at least 1.8 meters. Protect your bird feeders and houses effortlessly with our reliable squirrel blocker set, designed for durability and efficiency.
