The short version
True moles are rare here; check for gophers or voles. Find an active tunnel, then trap it. Repellents and sonic stakes rarely work.
- 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 Pierre 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. Gophers and voles here are busiest in spring and fall. One mole can dig a lot of tunnel.
- 1Raised ridges across the lawn.
- 2Round, volcano-shaped dirt mounds.
- 3Spongy patches underfoot.
- 4Tunnels along walkways and beds.
- 5Fresh mounds after rain.
- 6Dead 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
Good mole work is mostly finding the right tunnel. The provider maps the runway network in Pierre, flags the active sections, and picks two or three trap points. That map also becomes the baseline for follow-up visits in Pierre.
- Time
- 45–90 minutes
- Best for
- Every job; trapping fails without it
Mole-Labeled Baits
$100–$300 per application
Ask any Pierre 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 Pierre 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
Because neighboring yards feed new moles into a Pierre lawn, monitoring is what separates a finished job from a pause. Those are the seasons when Pierre moles push closest to the surface.
- 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 Pierre, but results are inconsistent. They can simply move activity to the neighbor's side. Most Pierre 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.
Round, volcano-shaped mounds come from deeper mole tunnels. Gopher mounds are crescent-shaped with a plugged hole.Which moles live around Pierre.
Both eat plants, so treatment differs from mole trapping. Shallow runways through the grass point to voles. If the mounds around Pierre are crescent-shaped, it's a gopher. Voles leave surface runways in the grass. Pocket gophers eat roots and leave crescent-shaped mounds. Most lawn tunnels and mounds here are pocket gophers or voles. True moles are uncommon around Pierre.
When they tunnel.
Frozen ground in winter sends them deeper. Summer heat and drought also push them down.
Moles have big, spade-like front feet built for digging. They eat earthworms and grubs, not plants.Finding an active tunnel.
Around Pierre, edges along walks and beds are the best bets. 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 Pierre.
- Spring: peak tunneling. Best time to trap. - Summer: highs near 89°F in Pierre push moles deeper. - Fall: a second burst near the surface. - Winter: lows near 7°F in Pierre. 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?
Moles by the numbers.
Around Pierre, 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. Around Pierre, because moles are solitary, several fresh ridges usually mean more than one animal. Around Pierre, tunnels often run just under the surface, with deeper nesting chambers below, and a single mole can maintain an extensive system across a yard. Around Pierre, moles do not eat plants; they tunnel for earthworms, grubs, and soil insects, and the ridges they leave behind are what most people notice.
What affects the price
- Seasonal monitoring plans versus one-time service.
- Number of moles present on the property.
- State rules that affect trap or bait choices.
- Season, since spring and fall book fastest.
- Irrigation and drainage corrections.
- Lot size and number of active runways.

Questions people ask
Why do repellents and sonic stakes not work on moles?
Moles get used to them or tunnel around them. Studies show little lasting effect.
How many moles are in my yard?
Usually just one to three.
Can I just flood the tunnels or fill them in?
It rarely works. Moles dig new tunnels or move a few feet away.
What kind of traps do professionals use?
Usually scissor or harpoon traps set in active runways. They're the most reliable method.
Will moles come back after they are removed?
New moles can move into empty tunnels. Catching newcomers early keeps damage small.
Do homeowners prefer DIY mole trapping or hiring a pro?
Around Pierre, many homeowners try trapping themselves first because it is the cheapest option and traps are sold everywhere. Around Pierre, a professional usually makes sense when tunnels keep reappearing after several weeks of trapping, when the damage covers a large area, or when you would rather not handle traps and dispose of animals yourself.
