Instructions
Look for one that will fit your needs. Bird feeders mounted on poles need baffles that are designed to adhere to a pole. Those that hang from chains will require different models that are attached above the feeder on the chain.
Pick a baffle that fits. If a squirrel can squeeze through a gap between the baffle and the pole, it will. You need a baffle that can mount flush with the pole to provide a true barrier to the squirrels. Measure the diameter of the pole on which you want to mount the squirrel baffle, and consider only those baffles that include your pole's circumference in their suitable range of use.
Avoid baffles made from plastics or particularly cheap materials if possible. Many of these can degrade with temperature fluctuations such as intense summer heat. A few cracks or fissures in the surface may provide a squirrel all the traction it needs to scale the barrier and enjoy the bird feed you lovingly set out for your cardinals.
How to Choose the Best Squirrel Baffle
Squirrel baffles are must-have items for bird lovers with bird feeders in the yard. Since squirrels care more about their appetites than your hobbies, it is important to build a few controls into any part of the yard where you want to attract birds but not the squirrels. Otherwise, the squirrels will invite themselves to every available crumb you put out. The squirrel baffle design is fairly simple, but there are a few things you'll want to consider before purchasing one.
