You must be tired of the squirrels in your backyard that try to get something from
the bird feeders you have put there for the birds visiting your backyard but with the squirrel proof, you can be sure they will not disturb you anymore. Bird feeders squirrel proof are meant to keep the squirrels and other animals you don't want away and they come in various types.
You can get a bird feeder squirrel proof that collapses or spins with the weight of the squirrel. These are made to only support small weights such as those of the birds so that when the squirrels try to get the food, the feeder starts to spin and the squirrel falls to the ground. You can also use caged bird feeders which can only allow birds to get inside so that the squirrel will be too big for the space left. There are those that are only meant for the small sized birds to get inside depending on what you want hence the squirrel proof will prevent other larger birds you don't want on your bird feeder as well as the squirrels.
You can also find ways of squirrel proofing your bird feeder which includes placing your bird feeder at a distance where the squirrel cannot reach as well as maintaining cleanliness around the area so the squirrels will not be attracted to the place. There are many companies producing squirrel ready bird feeders but important is to get one made of the best materials and is durable.
