And keep in mind that the word 'vole' applies to a number of different creatures (which, to add to the confusion, are often referred to as meadow mice or field mice, despite the fact that they aren't mice!).

Not only can voles destroy your lawn, they can kill your trees too. Unlike meadow mice, moles are insectivores, meaning that they aren’t interested in plants. Their diet usually consists of earthworms, grubs and insects. That’s why if you see chewed on greens, you can strike moles off your potential invaders list.

Voles, also called meadow mice or field mice, belong to the genus Microtus. Voles are compact rodents with stocky bodies, short legs, and short tails. Their eyes are small and their ears partially hidden. Their underfur is generally dense and covered with thicker, longer guard hairs. They usually are brown or gray, though many color variations exist.

The one thing they all have in common, however, is that they're nocturnal, breed rapidly, and can cause a lot of damage. Here's a good article about the different types of voles and their ranges (just ignore the advice to use poison baits; they are not safe for you and other living things).

I could maybe see a vole trying some out of curiosity, but I wouldn't rely on it for control. But I would give castor oil a try. Whenever people start to see signs of mole and/or vole damage on their lawn, I always suggest they start out with a castor oil-based repellant labeled for use on moles and voles. It doesn't actually harm the creatures; it just chases them off by making the soil smell bad under the surface.

Close-up of vole damage to beet roots (Beta vulgaris) Voles, Microtus spp., also commonly called meadow mice, are seldom seen though the damage they do to garden plants may be a too common sight. These are chunky, ground-dwelling rodents about 7 inches long with a tail that is less than 2 inches long. Young voles are gray.

The long-tailed vole can be distinguished from other Microtus species by its tail, which comprises 30% or more of its total length of 6 to 8 1/2 inches (15 to 21 cm). The long-tailed vole has gray to dark brown fur with many black-tipped hairs. The underparts are gray mixed with some white or yellow.

A. Voles are well known for eating the roots of plants, consuming Spring bulbs and tubers underground (other than daffodils, fritillaria, and garlic, which they avoid), and for chewing on the bark of trees and shrubs—especially over the winter.

The matter is that voles are very prolific breeders, and they can produce 4-6 litters per year. Litter sizes vary from 3 to 6. So, if you postpone facing the problem for later, they will quickly colonize the area and do much harm to your plot of land.

Voles, also known as meadow/field mice, are not mice, in fact. Though both of them belong to the same rodent family, they are classified into different groups. Voles are short-tailed, blunt-faced rodents, while mice are long-tailed, pointed-nose ones. The vole has a short tail and a blunt head. 1  Typically, the former pest is dark brown or gray, 2  and its size is about 3-6 inches long from nose to tail.  It has small ears and small eyes.
