I have a 4x4 wood post that's quite tall (probably 8 - 10 feet) that's used to hang lights and bird feeders. In particular, I have a suet feeder hanging from a hook about 4 feet off the ground. Unfortunately, the squirrels keep climbing the post and eating the suet. I don't dislike squirrels, but they eat a lot of suet and don't leave any for the birds (and the suet is too expensive compared to how much they eat).
What can I do to keep the squirrels off of the pole so that they can't eat the suet? (Simply getting a flavor that squirrels don't like, such as ones with pepper in them, would not be preferable since those kinds tend to be significantly more expensive).
I considered a squirrel baffle, but most of the ones I've been able to find are designed for small poles. The ones designed for 4x4 posts that I have been able to find seem to be a single piece, so I'm not sure how I would install them given that there are already multiple hooks and other obstructions that would prevent me from slipping it down to where it would need to go.
I've considered using Cocoanut oil or Vaseline, but I'm not sure if it's safe to use on the wood.
I did not install the posts myself - they came with the house - and I'm not sure how old they are or exactly how they were treated.
Also, I've probably already made this obvious from my question, but I'm a first-time homeowner and am quite inexperienced with home repairs.
