Wrap this baffle around a 4 X 4 post.
Baffle is 17″ in diameter. Smaller diameter wrap around baffles do not work.
Baffle should be 4.5 to 5 feet off the ground to prevent squirrels from jumping up past the baffle. Squirrels can also launch themselves from trees, decks etc. 12-15 feet so place your pole sufficient distance from launching points.
Watch Episode 2 of The Garden Gate for more information on Baffling the Squirrels.
