Voles caused significant damage to residential lawns in Winnipeg, Manitoba, by tunneling under snow cover during the winter [1].
This rodent activity creates a widespread landscaping issue for homeowners. When the snow melts, the underground tunnels collapse, leaving behind visible patches and holes that compromise the integrity of the grass.
These small rodents utilize the insulating layer of snow to survive the cold months [1]. While beneath the surface, voles feed on grasses and the roots of various plants [1, 2, 3]. This behavior allows them to remain active and protected from predators while simultaneously destroying the root systems of residential turf [2, 3].
The damage typically becomes apparent during the spring thaw. As the snow disappears, the structural support for the vole tunnels vanishes, leading to the characteristic surface depressions seen across the city [1].
Homeowners in the region have reported these patterns following the 2023-2024 winter season [1]. Because the rodents target the roots, the grass often dies in specific patches, making the damage difficult to repair without addressing the underlying infestation [3].
Experts said that the burrowing process is a survival mechanism for the animals [1]. The resulting holes can create uneven terrain on lawns, which may present minor tripping hazards or aesthetic concerns for residents [2].
“Voles burrow beneath snow cover to feed on roots and grasses.”
The prevalence of vole damage in Winnipeg highlights the intersection of urban landscaping and wildlife survival strategies. By using snow as a thermal blanket, voles can sustain populations that cause systemic damage to residential greenery, necessitating specific pest management and soil restoration strategies each spring.
