Wamt?
There must be a new Squirrel in town, the old ones know the score.
I've had the same feeders for years, and even seen squirrels hanging upside down to feed from them.
That's OK they never do any damage, they know what happens if they do.
This morning the plastic feeder had been chewed at the bottom and had been dragged halfway across the lawn.
I repaired it, re filled it, and put it back.
While I was out shopping, I picked up a new one.
When I got home, the (old)feeder had been chewed again, and was halfway across the lawn again.
I've now rigged up a revolving greasy plastic sleeve for the arm.
I'll see if that works, before putting out the new feeder.
If not, the traps are going out.
