We finally made it to the hardware store and found this light aluminum screen material (I think it’s meant to reinforce window and door screens). It comes rolled up like wrapping paper. I cut a piece to fit around the inside edge of the bucket, temporarily moved the compost into another bucket, put the screen inside my regular bin and duck taped it down around the top so that the compost wouldn’t get between the screen and the bucket edge when I roll it around. I suppose that if the squirrels can chew through hard plastic, it would seem likely that a thin aluminum screen would be a piece of cake, but we’ll see. Maybe they won’t be able to get any traction with their gross little teeth.
