Meadow voles are best treated with a suitable rodenticide such as Kaput that is labeled for Voles. Never use a product that is not labeled for the pest you are trying to control. It's like using a medicinal product. You have to read the product and label directions to be sure.
The next step is to use bait stations to hold this bait so that it is accordance with federal law. You can't just throw rat or mouse bait into a field. The stations that I recommend are called Protecta Mouse Stations. They are small and contain the bait so that only a mouse or vole can enter it to eat the bait. Place these stations near the holes, trails, etc. The bait and the stations are sold separately.
Whatever you decide to do, just know that this is a difficult issue. Meadow Voles are not easy to control. Using a systematic method of baiting and rebaiting, keeping track of the stations, knowing which stations are getting the hits, etc. helps tremendously in your efforts. This is an issue that can only be controlled. They will be back at some point, so once you know how to control them, next time is easier.
