FAQ - Answer
By far the most effective method of protecting small trees from vole feeding is through the use of an exclusionary device. Most materials will work but the most commonly used products are the ones called “tree tubes” or “tree shelters”. I’m sure you have seen them used in protecting small orchard or vineyard crops. They are flesh colored and come in various lengths. Additionally, mowing, dicing or spraying a weed free area around the base of the tree is another very effective means of limiting vole damage. They’re small animals and prefer thick cover for hiding protection. A weed free area should be considered even when using a tree shelter. Any material can be used to make your own shelter. Window screening works well as it is pliable and the mesh is such that voles cannot slip through. Regardless of what you use, be sure and monitor the trees since voles are known to burrow beneath the shield.
