Our hummingbird feeder has a dome, and yet the ants still get to the nectar. After reading your ideas, I came up with one of my own.
I used red electrical tape. First, one rotation, sticky side down, as usual, followed by a half twist, then wrapped with a wire hanger, sticky side out. The ants don't like it, it cheap, no harmful effects to the ecosystem.
How do you like my idea?
I think that is a great idea.
My only concern is that you will need to keep using more tape, as the sticky part gets coated in dust from the air. Other than that, it sounds brilliant. Thanks for the idea.
