I don’t think any plants are going to be effective;
we are in the process of adding ~150 fruit trees and we live in the country surrounded by farms and fields, and a large vole population
there is a very effective cheap simple way to eliminate voles/mice
I bought a single 10ft 2" PVC and cut in into 9 pieces and made 3 bait stations like this - just need a 3 tee connector, cap and 12" 1/8" threaded rod and washer/nuts
you can see the bait being eaten, and within a month, no more problems
very happy and effective
