  • 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.

Treatment options and typical costs

Runway Identification and Activity Survey

$75–$200

The flattening test is simple: press, mark, recheck in 24 hours. Tunnels reopened overnight are active and become the trap sites for the Ann Arbor job. Mounds get noted too, since they mark deeper tunnels below Ann Arbor lawns.

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

Mole-Labeled Baits

$100–$300 per application

Ask any Ann Arbor provider what product they use and to confirm it is labeled for moles. Label directions are legally binding, and off-label use is not acceptable. Used correctly, baits give Ann Arbor yards a second tool alongside traps.

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

Follow-Up Monitoring

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

After traps catch or tunnels go quiet, a provider flattens all remaining runways and watches for new ridges. No fresh activity for a week or two means it worked. New ridges in Ann Arbor mean a second animal has moved in.

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

Lawn, Moisture, and Bed Exclusion Work

$150–$450 depending on scope

Repellents based on castor oil may push moles around temporarily in Ann Arbor, but results are inconsistent. They can simply move activity to the neighbor's side. Most Ann Arbor providers treat them as a minor add-on, not a plan.

Time
1–4 hours
Best for
Repeat problems; protecting beds and small areas

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

Which moles live around Ann Arbor.

They eat earthworms and grubs, not roots. Moles are insectivores, not rodents. Hairy-tailed moles prefer woods. Star-nosed moles favor wet spots here. It's gray, about six inches long, with big spade-like front feet. The eastern mole is the one digging up lawns around Ann Arbor.

When they tunnel.

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

Finding an active tunnel.

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

A year of moles in Ann Arbor.

  • Spring: peak tunneling. Best time to trap. - Summer: highs near 83°F in Ann Arbor push moles deeper. - Fall: a second burst near the surface. - Winter: lows near 17°F in Ann Arbor. Ground freezes; moles go deep.

Mole, gopher or vole?

  • Mole: raised ridges and round, volcano-like mounds. - 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.

What works, and what doesn’t.

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

Protecting garden beds.

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

Lawn care that helps.

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

Signs the problem is over.

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

Choosing a trap.

  • Scissor traps: set straddling an active runway. - 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.

Mole myths.

  • Chewing gum in tunnels: no evidence it works. - 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.

Moles aren’t all bad.

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

Fixing the lawn afterward.

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

Moles, kids and pets.

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

What a mole visit looks like.

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

Moles, voles or gophers?

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

Watering and moles.

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

Flower beds and borders.

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

Questions to ask before you sign.

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

What affects the price

  • Irrigation and drainage corrections.
  • State rules that affect trap or bait choices.
  • Property bordering fields, woods, or streams.
  • Provider type: wildlife operator versus lawn company.
  • Soil type: rocky or clay ground slows trap sets.

Mole species

The eastern mole makes the surface tunnels; the star-nosed mole makes the big soil volcanoes.

Star-nosed moles, because their tunnels run much farther below ground
Hardest to control

Surface-set traps miss them.

Grub myth

Grubs are only a portion of an insectivore's diet of insects, worms and other invertebrates.

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.

Should I repair the lawn before or after trapping?

After. Fixing it first hides the tunnels you need to find.

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.

Do I need a permit to trap moles?

Rules vary by state. Ask a local company what's allowed in Michigan.

Will moles come back after they are removed?

New moles can move into empty tunnels. Catching newcomers early keeps damage small.

Do ultrasonic mole repellers work?

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

Do people hire professionals for mole removal?

Around Ann Arbor, ask about the number of visits and whether the follow-up is included.
