What it is, and what it costs you.

Voles are small, short-tailed rodents that live in the grass.

Most of their damage happens out of sight, under the snow, and shows up all at once when it melts.

What you find in spring is a maze of runways across the lawn, about two inches wide, with small open holes along them.

Shrubs and young trees can be chewed bare at the base.

Rich looks for the burrow openings still in use along those runways and treats them.

That reaches the nests underneath, not just the trails on top.

Field signs

How to tell it is voles.

  • Surface runways

    Narrow trails clipped down to the dirt, running across the lawn and along fences.

  • Small open holes

    Holes an inch or two across along the runways, with no mound of dirt around them.

  • Chewed bark

    Gnawed bark at the base of shrubs, roses and young fruit trees, often hidden by snow until spring.

  • Damage after melt

    The worst of it appears as the snow pulls back in March and April.

The PERC® method

Every tunnel, in seconds.

PERC® stands for Pressurized Exhaust Rodent Control.

Instead of a bait on the surface or a trap at one hole, the treatment goes down the burrow and through it.

How the PERC® method treats a burrow Cross-section of a prairie dog burrow. A probe from the rig goes into one entrance. Pressurized gas flows down through the connected tunnels to the nest chamber, a side chamber and the other entrances. 1 2 3 PROBE IN THE ENTRANCE NEST CHAMBER OTHER ENTRANCES

  1. 1

    Probe in

    A probe from the rig goes into each active entrance. Several hoses work at once.

  2. 2

    Pressure on

    Pressurized gas, about 2.5 percent carbon monoxide, fills every connected tunnel.

  3. 3

    Purged in seconds

    The burrow is purged of air before the rodent can get out another entrance.

The job

How Rich handles it.

Vole numbers swing a lot from year to year.

A winter with deep, lasting snow can leave a lawn covered in runways by spring.

It happens even on property that never had a problem.

The plan depends on what Rich finds.

A lawn with runways but few active holes needs less work than a pasture edge full of burrows.

The estimate reflects that.

Rated 5 out of 5 stars.

Rich, the owner, is very knowledgeable & friendly. Did an amazing job, highly recommend.

Satisfied with the final outcome.

  1. Walk the runways

    Rich follows the runways to find which holes are still in use.

  2. Treat active holes

    The burrows under the active holes get the pressurized treatment.

  3. Watch the edges

    Voles move in along fence lines and from tall grass. Any new activity gets a follow-up.

Questions

Common questions.

Voles or gophers?

Voles leave open holes and surface runways. Gophers leave fan-shaped mounds with plugged holes.

If you are not sure, describe it on the phone or send a photo by text.

When is the best time to call?

As soon as you see fresh runways or chewed bark.

Spring, right after the snow, is when most people notice them.

Will the lawn grow back?

Runways usually fill back in once the voles are gone, with a season of watering and mowing.
