IDK about rodents. I know that spray foam is hard to remove in the future if you need to.

I have had things shipped to me where they sprayed the foam inside a plastic bag pressed in between the item and the box. That contains the foam in the bag, so it does not stick to the item, but provides the desired cushion. Something like that might work. Then the foam would conform to the space but not stick to everything.

I have not tried that.
