Stinging nettle against voles
A very effective way to evict voles permanently is to fill the burrows of the voles with undiluted stinging nettle.
Caution: The manure has an unpleasant odor (therefore acts as a repellent for the voles). Therefore, when using in the vicinity with caution, if you do not want to be self-evicted. :-)
The prerequisite is that you do this over several weeks (2-3 weeks consistently every day). This sells the pests in a natural way.
