In my backyard setup I have a squirrel proof feeding station
that is actually squirrel proof.

But to attract woodpeckers I have a suet cage hanging from
a tree. Not only do the squirrels knock it off the tree, but they
open up the cage and get the whole suet cake.

I've seen suet cakes advertised that come with hot peppers,
which squirrels are suppose to hate.

Any idea if that works?

Thanks
Doug
