Voles in Calgary Lawns: Signs, Damage & What to Do After Snow Melt

When winter ends in Calgary, many homeowners expect their lawns to bounce back. Instead, you may notice strange trails, dead grass, and damaged plants appearing across your yard.

These are common signs of vole activity—a hidden problem that develops beneath the snow throughout winter.

What Are Voles and Why Are They a Problem in Calgary?

Seeing tunnels and dead grass after snow melt in Calgary? Learn how voles damage lawns in winter and how to prevent and repair it quickly.

Vole Damage in Calgary After Snow Melt: Signs, Causes & Solutions

The damage only becomes visible in spring when snow melts, revealing tunnels and dead grass

Voles are small, mouse-like rodents that live outdoors and thrive in grassy areas. Unlike typical house mice, voles create surface tunnels (runways) and feed on:

Grass and roots
Plants and garden vegetation
Tree bark near the base

During Calgary’s winter, snow acts as insulation—allowing voles to stay active, reproduce, and cause damage unnoticed.

Signs of Vole Activity After Snow Melt

As the snow melts, the damage becomes visible. Watch for these key signs:

1. Runways Across Your Lawn

Thin, winding trails across your grass are the most obvious sign of vole activity.

2. Dead or Patchy Grass

You may see brown, flattened, or thinning areas caused by feeding and tunneling.

3. Small Holes in the Soil

Voles create small burrow openings (about 1–2 inches wide).

4. Chewed Trees and Shrubs

Damage at the base of trees or plants is a strong indicator of vole feeding.

5. Soft or Uneven Ground

Underground tunnels can make your lawn feel spongy when walked on.

Damage Caused by Voles

Voles may be small, but they can cause serious and costly damage, including:

Destroying large sections of your lawn
Killing plants and shrubs
Damaging tree roots and bark
Creating long-term landscaping issues

Because they reproduce quickly, a small infestation can turn into a major problem in a short time.

What to Do If You Have Voles in Your Yard

1. Act Early

The best time to control voles is right after snow melt, before populations grow.

2. Clean Up Your Yard

Remove debris, excess mulch, and tall grass where voles hide.

3. Protect Trees and Plants

Install tree guards to prevent bark damage.

4. Monitor Activity

Keep an eye on new trails, holes, or fresh damage.

5. Call Professional Pest Control

For active infestations, professional treatment is the most effective solution.
