It is a progress to get squirrel to use this feeder and stay away from my bird feeders. First few days mounted it close to our whole peanut bird feeder which squirrels like to attack first, fill it up with their favorite walnut. Once they discovered it and used it on daily base for a few days, I moved it to the other side of the yard. Since there is no vegetation nor other form of climbing path, I put ladder there to allow squirrel to rediscover it for another two days before I removed the ladder. Once they know it is there, they will figure out a way to get there. Now it is fun to watch squirrels fight for the feeder and chase on the fence. They would leave my whole peanut for blue jays to carry away for most of the time and lease clean up for me.
Side notes: I do have nutty squirrels chewing on the feeder opening right after I mounted it up. They are not stopping and making sharp edge on the holes which make cleaning harder. I reached out to customer service, since this is expected wild life behavior and not covered by warranty, I purchased replacement side panel, the customer service is very helpful to get me the replacement part and recommended me to look into chew guard for future protecting. Great experience with the company and product.
