  • Usually one to three moles.
  • Find an active runway first.
  • Traps work best; repellents rarely do.
  • Moles eat earthworms, not plants.
  • Fix the lawn after trapping.

Homeowners in Spokane Valley with tunnels, ridges or mounds in the lawn.

What to look for

Moles don't eat plants. They hunt earthworms and grubs. Their tunnels lift turf, dry out roots and trip people up. Moles around Spokane Valley are busiest in spring and fall. They tunnel near the surface after rain. One mole can dig a lot of tunnel.

  • Raised ridges across the lawn.
  • Round, volcano-shaped dirt mounds.
  • Spongy patches underfoot.
  • Tunnels along walkways and beds.
  • Fresh mounds after rain.
  • Dead turf strips over tunnels.

Why it’s worth acting soon

  • Tunnels spread across the lawn.
  • Mounds make mowing harder.
  • Ridges become trip hazards.
  • New moles move into empty tunnels.

Treatment options and typical costs

Runway Identification and Activity Survey

$75–$200

Expect questions about when and where mounds appeared. Then they flatten runways to confirm which lines are live. The result is a short list of Spokane Valley trap locations, not guesswork.

Time
45–90 minutes
Best for
Every job; trapping fails without it

Active-Runway Trapping

$150–$400 per visit; multi-visit plans $300–$900

Because a single mole can cover a large area, one yard in Spokane Valley often holds only one or two animals. Trapping removes them one by one and confirms success. Most Spokane Valley providers plan on several rechecks before calling a job finished.

Time
30–60 minutes per visit, over several visits
Best for
Most yards; the most reliable method

Follow-Up Monitoring

$50–$150 per visit; often included in plans

Afterward, flatten ridges and call if they pop back. That simple test lets you monitor between visits. It also tells the provider exactly where to set in Spokane Valley next time.

Time
20–30 minutes per visit
Best for
Every trapping job; confirms the yard is clear

Mole-Labeled Baits

$100–$300 per application

Worm-shaped baits labeled for moles mimic the earthworms moles eat. They go inside active runways, as the label directs. For Spokane Valley homes, baits are usually paired with trapping rather than used alone.

Time
30–45 minutes
Best for
Large or hard-to-trap areas; used exactly as labeled

Prices are typical published ranges. Ask what’s included before you compare quotes.

Which moles live around Spokane Valley.

Moles are insectivores, not rodents. They eat earthworms and grubs, not roots. Around Spokane Valley, Townsend's, coast or broad-footed moles do the digging. They push up more mounds than eastern moles.

When they tunnel.

Frozen ground in winter sends them deeper. Summer heat and drought also push them down.

Raised ridges are feeding tunnels just under the turf. Many are used once and abandoned.

Finding an active tunnel.

If it's raised again, it's active. Main runways often follow edges: walks, fences and beds. Lawns from Spokane Valley out to Spokane show the same pattern. Look for fresh ridges and mounds after rain. Step down a short stretch of tunnel and mark it. Check it in a day or two.

A year of moles in Spokane Valley.

  • Summer: highs near 84°F in Spokane Valley push moles deeper. - Fall: a second burst near the surface. - Winter: lows near 23°F in Spokane Valley. Ground freezes; moles go deep. - Spring: peak tunneling. Best time to trap.

Mole, gopher or vole?

  • Gopher: crescent-shaped mounds with a plugged hole. - Vole: surface runways and small holes in the grass. - Damage: moles don’t eat plants; gophers and voles do. - Mole: raised ridges and round, volcano-like mounds.

What works, and what doesn’t.

  • Sometimes: labeled baits, used deep in tunnels. - Rarely: castor oil, sonic stakes, gum or flooding. - Rarely alone: grub control, since they mostly eat earthworms. - Works: traps set in active runways.

Protecting garden beds.

Raised beds can get a mesh floor before you fill them. It's work up front, but it lasts for years. Bury quarter-inch hardware cloth around beds, about two feet deep. Bend the bottom edge outward.

Lawn care that helps.

Healthy turf recovers from tunnels faster. Grub control alone rarely moves moles on. Water deeply but less often. Constantly wet lawns draw earthworms, and moles follow.

Signs the problem is over.

  • Stepped-down runways stay flat. - Traps stay untouched for several checks. - New ridges? Another mole may have moved in. - No new mounds for two weeks.

Choosing a trap.

  • Harpoon traps: set on top of a pressed-down ridge. - Tunnel traps: sit inside a dug-out runway. - Placement: main runways beat fresh feeding ridges. - Rules: check what your state allows first. - Scissor traps: set straddling an active runway.

Mole myths.

  • Castor oil: may move them briefly, not away. - Moles eat bulbs: no, voles using their tunnels do. - Many mounds, many moles: usually it’s one or two. - Flooding tunnels: they just dig new ones. - Chewing gum in tunnels: no evidence it works.

Moles aren’t all bad.

A mole in a field may be fine to leave. In a front lawn or garden, most people want them gone. Moles loosen and aerate soil. They eat grubs and other insect larvae.

Fixing the lawn afterward.

Water to settle the soil. Overseed bare spots in spring or fall. Wait until the mole is caught. Rake mounds flat and step ridges down.

Moles, kids and pets.

Baits must go deep in tunnels, exactly as the label says. Digging dogs can wreck a lawn faster than moles. Moles don't bite unless handled. Keep kids and pets away from traps.

What a mole visit looks like.

Traps go into the main runways. They check traps every day or two. The tech walks the lawn and maps the tunnels. They test which runways are active.

Moles, voles or gophers?

  • Voles: narrow surface runways through the grass. - Gophers: crescent-shaped mounds with a plugged hole. - Chipmunks: small clean holes with no soil around them. - Moles: raised ridges and round, volcano-shaped mounds.

Watering and moles.

Water deeply and less often instead of a little every day. Fix leaky sprinklers that leave soggy corners. Moles follow moist soil, where worms rise near the surface.

Flower beds and borders.

Plants wilt when their roots are left hanging in air pockets. Press tunnels down firmly and water to settle the soil. Moles tunnel under beds looking for worms, not to eat plants.

Questions to ask before you sign.

  • Which method will you use? - How often will you check traps? - What if another mole moves in? - Is lawn repair included? - Is it a mole, gopher or vole?

Moles by the numbers.

For Spokane Valley homes, because moles are solitary, several fresh ridges usually mean more than one animal. For Spokane Valley homes, before you hire, walk the yard and flatten a few ridges with your foot, then check back the next day — the ones that are raised again are the active runs a plan should target. For Spokane Valley homes, moles do not eat plants; they tunnel for earthworms, grubs, and soil insects, and the ridges they leave behind are what most people notice. For Spokane Valley homes, tunnels often run just under the surface, with deeper nesting chambers below, and a single mole can maintain an extensive system across a yard.

What affects the price

  • Provider type: wildlife operator versus lawn company.
  • Irrigation and drainage corrections.
  • Mole-labeled bait applications added to trapping.
  • Seasonal monitoring plans versus one-time service.
  • Lot size and number of active runways.
  • Soil type: rocky or clay ground slows trap sets.

What bothers you most about moles?

When to call for help

Call if new mounds keep appearing for more than a week. if you can't find an active runway. A pro can usually catch the mole within a few visits.

What you can do yourself

Skip sonic stakes, gum and flooding. Set the trap exactly as the instructions say. Trapping yourself can work.

Questions people ask

Are mole baits safe around pets and children?

Use them only as the label directs, deep in tunnels. Traps are often the safer choice.

How long does professional mole control take?

Usually one to three weeks of regular trap checks.

Is the mole still in my yard?

Step down a short section of tunnel. If it's raised again in a day or two, it's active.

Will grub control get rid of moles?

Rarely. Earthworms are their main food. Killing grubs alone usually doesn't move them on.

Are moles rodents?

No. They're insectivores, related to shrews. They eat earthworms and grubs, not plant roots.

Do ultrasonic mole repellers work?

No. For Spokane Valley homes, there is no scientific evidence that ultrasonic or vibrating devices repel moles, and extension offices consistently advise against relying on them. For Spokane Valley homes, moles have poor eyesight and live almost entirely underground, where airborne sound barely reaches them. For Spokane Valley homes, if you try a sonic stake, watch for fresh ridges over two weeks; if activity continues, switch to traps in the active runs.

Is the GopherHawk trap popular for moles?

For Spokane Valley homes, the GopherHawk is a commonly discussed scissor-jaw trap, but popularity is not the same as effectiveness. For Spokane Valley homes, like any trap, it works only when set in an active run and checked often. For Spokane Valley homes, choose a trap you can set correctly and check daily, and focus on finding the active tunnel first.

When are moles most active in Spokane Valley?

Spring and fall, especially after rain. Frozen winter ground sends them deep.

Are moles common in Spokane Valley?

Yes.
