I don't have too much of a mole/vole problem, but they do get some lilies. Last year I planted some of Lisa's, and some from The Lily Garden that were quite costly to me. All precious, especially Lisa's. I had read somewhere if you surround your lilies with daffodils the moles/ voles won't go past the daffs.
So I bought bags of daffs from ADR bulbs, and planted them around the precious lilies.
Result so far is no mole/ vole damage where the daffs were planted around the lilies. Some on the other lilies.
I had heard you can plant the daffs quite a ways apart, and I did about a foot or so.
