I'll share a fun and effective method to get squirrels off your bird feeders. Hang the bird feeder high up, and on a good amount of radius underneath, put a bunch of small nails (and I mean a good bit) into the ground, sticking out. Put long noticeable wooden plank leading from your porch or something (a window is preferable) to the feeder. Add another permanent plank leading downward, spraypaint it black, and nail a troutload of small nails from the bottom up, so you've got a spiked runway. When you see the squirrels smurfing around on the bird feeder, simply pull the temporary plank away from the feeder, and the squirrels will be faced with either jumping down into a spike pit, or walking down the spiked runway. You can do what you want with the bodies if they don't make it home, but they won't come back if they do.
