This non-toxic method of preventing squirrels from accessing bird feeders can save you hundreds of dollars each year on wasted food.
First, you'll need a section of PVC pipe the height of your bird feeder pole. The size pvc pipe is entirely dependent on the size of the post/pole that the bird feeder rests on.
Slide the pole down into the PVC pipe and secure the pole itself into the ground. The pvc pipe
doesn't need to be secured to the ground or in the ground.
Apply a coating of wax to the pvc pipe using a cotton cloth. Be sure to "grease" the pole well.
Here's what happens when the squirrels attempt to jump on the waxed pole:
Be sure that you DON'T paint the pvc pipe first as this changes the texture and the squirrels WILL still be able to climb it, even after it's waxed.
