Mice vs. voles - what's the difference?

What is the difference between a vole vs. a mouse?

Quick comparison: mouse vs. vole

  • Mice have large ears, long tails, and pointed snouts; voles have small ears, short tails, and rounder, blunter faces
  • Mice tend to move indoors seeking food and shelter; voles usually stay outdoors, tunneling through lawns and gardens
  • Mice gnaw on stored food, wiring, and packaging; voles chew through plant roots, bulbs, and bark at the base of trees
  • Mice leave smooth, rope-like runways along walls; voles carve visible surface trails through grass

The difference between voles and mice

Mice and voles are often mixed up since both are small, brown, and quick to scurry out of sight, but they cause very different problems. A mouse infestation usually means unwanted guests inside your walls and cupboards, while a vole problem shows up as damaged turf, chewed roots, and dying plants in your yard.

Mice

Mice are small rodents that seek out warm, sheltered spaces close to a food source.

  • Appearance - Grayish-brown fur, large ears, and a tail as long as their body
  • Habitat - Indoors, nesting in wall voids, attics, and cluttered storage areas
  • Behavior - Active at night, gnawing on food packaging, wiring, and building materials
  • Risks - Can spread bacteria through droppings and cause damage by chewing through wires and insulation

Voles

Voles, sometimes called field mice, are burrowing rodents that spend most of their time outdoors.

  • Appearance - Brown to gray fur, small ears, short tail, and a rounder, blunt face
  • Habitat - Lawns, gardens, and mulched beds, where they dig shallow surface tunnels
  • Behavior - Feed on grass, roots, bulbs, and the bark at the base of young trees and shrubs
  • Risks - Can kill plants and trees by stripping roots and bark, and their tunneling can leave visible tracks across your lawn

Signs of an infestation

Mice tend to leave droppings, gnaw marks, and greasy rub marks along baseboards and in cupboards, along with the occasional scurrying sound at night. Voles are usually spotted through their damage rather than the animal itself, with surface trails through grass and girdled bark near the base of trees or shrubs. If you're noticing either pattern, a pest control technician can confirm which pest is behind it.

Prevention tips

Keeping mice out starts with sealing gaps around your home's foundation, doors, and utility lines, along with storing food in airtight containers. For voles, keep grass trimmed, clear away mulch piled against tree trunks, and consider rodent exclusion services if damage keeps returning to your yard.

Frequently asked questions

Mice are more likely to be found indoors with large ears, long tails, and signs like droppings or gnawed packaging. Voles stay outdoors, have short tails and small ears, and leave behind chewed roots, damaged bark, or trails through your lawn.

Voles are often called field mice, but they're a distinct species from house mice. Voles are stockier, have shorter tails, and spend their time burrowing outdoors rather than seeking shelter inside homes.

Mice can multiply quickly once they find a way into your home.

Voles can quietly damage your lawn and garden before you notice they're there.
