Meadow Vole

Microtus pennsylvanicus

The meadow vole (Microtus pennsylvanicus) is a small rodent that digs shallow runways in lawns and gardens. Less dangerous than the rat, it can still do serious damage to plant roots, lawns and vegetable crops. It breeds so fast that populations can explode in a single season.

§1Distinctive features

How to identify it

A small, stocky rodent, 9 to 12.5 cm long, with a short tail of 3.5 to 6.5 cm. Dark brown fur on the back, grey on the belly. Rounded snout, short ears almost hidden in the fur. Do not confuse it with the deer mouse, which is slimmer, with large black eyes and a tail as long as its body.

§2Habitat

Where to find it

It lives in meadows, lawns, gardens and fields. It digs shallow burrows linked by runways visible in the grass. It can get into basements in the fall. It does not hibernate: all winter long, it moves around and feeds under the snow, where it keeps extending its runways and gnawing bark.

§3Reproduction

Lifecycle

PHASE 1
Intense breeding
Gestation of 20 to 23 days
PHASE 2
Young
Females fertile from 3 weeks
PHASE 3
Adult
Lifespan of 2 to 16 months

Left alone, a population can grow very quickly during the breeding season.

Frequently asked questions

Look for the telltale runways in the grass (surface tunnels) and small burrow entrances 3 to 5 cm across.
Partly. Cats can reduce populations locally, but they cannot eliminate an established infestation.
For small populations, mechanical traps are enough. For a widespread infestation, a professional is recommended.
WHERE WE WORK

The meadow vole digs its runways under the lawn and attacks the roots and bark of young trees. It is what people in Quebec commonly call a field mouse, and the treatment is the same. Properties bordering a field or woods are the hardest hit, which explains the number of calls on the outskirts of Granby, Sherbrooke, Farnham and Acton Vale.

React quickly, sleep well.

The longer the infestation lasts, the more expensive it becomes.
