If you want to know how to get rid of voles without killing them, deterrents are a great choice. Applying a strong vole repellent or voles repellent around your garden borders keeps them away safely. Liquid or granular vole repellent products usually contain castor oil, which makes the soil taste terrible to a vole. However, if you already have a massive infestation, combining a voles repellent with a solid vole trap strategy is the best way to get rid of voles permanently from your property.
