Squirrels can be a common nuisance when it comes to bird feeders. To keep them away, choose feeders with squirrel-resistant features like baffles or cages. Placing the feeders in a location that is difficult for squirrels to access, such as far away from trees or using pole-mounted feeders, can also be effective. Additionally, offering squirrel-proof food, like safflower seeds, can deter them from visiting the feeders.
