Mary, I've never seen voles here, and I've only ever seen 2 moles, and they were both dead. One in my front lawn, and the other on my back walkway, by my lilies and daffs. I've never seen any evidence of either living in my garden.
What seems to work is a perimeter of the daffodils around the plants that you want to protect.
Here's mini narcissus 'Minnow' around a set of lilies.
And N. Delibes around OT Purple Prince
Edited to add the mini daff is 'Minnow', not 'WP Milner'.
