Would there be a simple way to stop mice climbing up a bamboo stick?

You need a downwards facing cone or a circular collar around it.

Enough that the mouse cannot reach the edge or jump around it. This will
also catch some of the overspill before it hits the ground - birds are
messy eaters.

Mice struggle to climb 15mm copper pipe which is what I use to support
my bird feeder. A band of grease part way up stops squirrels too. The
latter will rip a spot welded one apart if they can get to it.
