The squirrels here have gotten SO smart that they are circumventing literally ALL the "squirrel resistant" feeders.... other than my feeders which are rather high on a pole with a metal baffle. My squirrel "proof" feeder on the deck was good for about two years.... then the little buggers figured it out.... ARGH!
...Not to mention that a RACCOON has been emptying it nightly. DOUBLE ARGH!
Bit the bullet and found what's called the "Squirrel Buster Plus", made by Brome Bird Care in Quebec. It's PRICEY, but reviews on it are excellent. Put it up today.... will report back on how well it works and will try to include a pic.
... Always ticks me off when a RODENT is smarter than me.... well, maybe that wouldn't take too much!
