Every spring in Minnesota, homeowners uncover a familiar sight once the snow melts: winding brown trails snaking across the lawn, dead grass matted flat in irregular patterns. If that sounds familiar, you've got vole damage.
The good news? It's repairable. Here's how to assess the damage and get your lawn back.
What Are Voles?
Voles (sometimes called meadow mice) are small rodents that burrow and tunnel through grass — especially under snow cover where they're protected from predators. Unlike moles, which dig underground, voles travel along the soil surface and feed on grass crowns and roots.
A long Minnesota winter with deep, persistent snow is ideal vole habitat. By the time the snow clears, a family of voles can create an extensive network of surface runways throughout your lawn.
Assessing the Damage
Once the ground firms up, walk your lawn and identify:
- Surface runways — matted, dead-looking trails 1–2 inches wide zigzagging through the turf
- Chewed grass crowns — look closely at the ends of affected grass; you may see gnaw marks
- Bare soil patches — areas where voles fed heavily and the grass is completely gone
- Entry holes — small openings into the root zone or mulch beds
In most cases, vole runways look worse than they are. If the grass crowns and roots are still intact (not chewed off at the base), the turf will often recover on its own once it starts actively growing.
Step-by-Step Repair
1. Rake Out the Dead Material
Use a metal tine rake to loosen and remove the matted dead grass in the runways. This improves air circulation and lets sunlight reach the soil surface, which speeds recovery.
Don't be too aggressive — you're trying to remove dead material, not tear up the underlying soil.
2. Let It Breathe
Give the affected areas a week or two after raking to see what recovers naturally. Some runways will fill in on their own as surrounding grass spreads, especially in mild damage cases.
3. Overseed Bare Spots
For areas where the grass is gone, overseeding is the fix. Wait until:
- Soil temperature is consistently above 50°F (typically late April in the Twin Cities)
- Frost is no longer a threat
- The lawn is actively growing
Choose a grass seed blend that matches your existing turf. Apply at the recommended rate, rake lightly into the soil surface, and keep the area consistently moist until germination.
4. Fertilize for Recovery
A well-timed spring fertilizing application helps damaged areas recover faster by giving the existing grass the nutrients it needs to spread and fill in thin spots. This is also the time to apply pre-emergent weed control to the rest of your lawn — though avoid applying pre-emergent directly on areas you're overseeding.
When to Call a Professional
If the vole damage is extensive — covering large portions of the lawn or multiple bare patches — professional overseeding and aeration may be the most efficient repair. Core aeration combined with overseeding produces faster, more even results than hand-seeding alone, especially on larger Twin Cities properties.
