Vole vs Mouse

Voles and mice are both small rodents and are often called field mice. A house mouse is a slim animal 2.5 to 3.75 inches long with a tail of 2.75 to 4 inches, large ears and eyes and a pointed nose. A vole is a compact, heavy-bodied rodent about 5 to 8 inches including a short, short-furred tail.

Where the signs are matters as much as the animal. Voles live outdoors, make well-traveled runways beneath grass and ground cover and rarely come into houses. House mice can live indoors their entire lives. Vole droppings are about 3/16 inch and greenish when fresh, while mouse droppings are about 1/4 inch, rod-shaped and pointed.

When you are looking at which

Vole

• The animal is stocky with a short tail, small eyes and ears barely visible in its fur.
• You find narrow runways in the grass or under mulch leading to burrow holes.
• Tree bark is gnawed in irregular patches near ground level.
• There are no signs inside the house.

Mouse

• The animal is slim with big ears, large eyes and a pointed nose.
• Its tail is long and almost hairless, about as long as its body.
• You find 1/4 inch rod-shaped droppings in kitchen cupboards, attics or walls.
• It climbs walls and shelves with ease.

How this works

The quiz uses five cues from university pest-management guides: tail, ears and eyes, snout, where the signs are, and droppings. A short tail with a blunt snout is the clearest vole signal, and runways in grass back it up, while droppings are the weakest because the sizes are close.

It compares voles with the house mouse, not every field mouse. White-footed and deer mice, shrews and young rats differ. If you have damage but have never seen the animal, a local extension office can help identify it from the pattern of damage.

Where these numbers come from

The figures and defaults on this page are based on:

• University of California IPM: Voles (Meadow Mice), Vole size, short tail, runways, burrow holes, droppings and house mouse contrast (checked October 2026)
• Penn State Extension: Voles, Tail, snout, runways and damage patterns of voles versus mice (checked October 2026)
• Cornell Integrated Pest Management: Mouse and Rat Biology and Behavior, House mouse size, tail, ears and nose (checked October 2026)
• Utah State University Extension: IPM for Rats and Mice, House mouse droppings and climbing ability (checked October 2026)
