Get the big square varmit cage guard. I know Academy used to sell them. I assume they still do. If it's taking them two weeks to clean your feeder out, you don't have that many coons. It should only take them a week or less. You need some kind of varmit guard. The one I mentioned above works very well. Try putting out a live box trap. A neighbor of mine put a couple out around feeders last season and caught 14. Some people put grease on the legs of the tripod.
