Where to place squirrel feeders?

Location #1. Side walls of your house. Mounted feeders are great for some reasons: they are steady and handy. Corn cob squirrel feeders are great for side walls. This is probably one of the most popular type. Downside? They are semi-permanent.

Location #2. Hanging feeders. These kinds are a bit more challenging. Unlike birds, squirrels have no wings which means that they need to climb, stand on a ledge or tree branch or hang onto something while feeding. If you get hanging feeders, make sure they have an actual ‘access’ to it – support ledge or fence wall.

Location #3. Mount on a tree. Some feeders can be easily mounted on a tree. They are great for aesthetics. Unless the tree is near your house and you can still have fun watching them while holding your coffee mug in the morning then it is probably a good choice. Metal feeders are ideal for feeders on trees.
