Keep squirrels off bird feeders by greasing the bird-feeder pole.
How to Keep Squirrels Off Bird Feeders
For years I have heard about various deterrents to keep squirrels and raccoons out of bird feeders. Recently, I was fighting off both determined critters when I hit on a solution: Grease the pole!
I used axle grease because it was handy, but you could coat the pole with used motor oil. Now the sunflower seeds and thistle are just for the birds.
