The short version
Moles are usually one to three animals. 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.
Anyone in Ames watching their lawn get dug up.
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 Ames are busiest in spring and fall. They tunnel near the surface after rain. 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
Across Ames, a survey also looks at what is feeding the moles: soil moisture, worm density, and grub activity. Ridges along foundations, walks, and bed edges usually mark main runways. Mapping them first avoids traps in dead tunnels.
- Time
- 45–90 minutes
- Best for
- Every job; trapping fails without it
Lawn, Moisture, and Bed Exclusion Work
$150–$450 depending on scope
A pro may suggest aerating and fixing wet spots. Drier, firmer soil holds fewer worms near the surface. That makes the yard a poorer feeding ground.
- Time
- 1–4 hours
- Best for
- Repeat problems; protecting beds and small areas
Active-Runway Trapping
$150–$400 per visit; multi-visit plans $300–$900
Scissor traps close from the sides; harpoon traps strike down. Both work lawns when placed on a straight, active runway with the soil packed properly. Placement and rechecks matter more than the trap brand in Ames.
- Time
- 30–60 minutes per visit, over several visits
- Best for
- Most yards; the most reliable method
Mole-Labeled Baits
$100–$300 per application
In larger Ames properties where trapping every runway is impractical, mole-labeled baits can reach tunnels traps cannot cover. They go into active tunnels and the openings are closed. Pets and children should be kept off treated Ames runways per the label.
- Time
- 30–45 minutes
- Best for
- Large or hard-to-trap areas; used exactly as labeled

Hardware cloth buried around beds keeps moles out of the places you care about most.Which moles live around Ames.
It's gray, about six inches long, with big spade-like front feet. Moles are insectivores, not rodents. They eat earthworms and grubs, not roots. The eastern mole is the one digging up lawns around Ames.
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.
Step down a short stretch of tunnel and mark it. Check it in a day or two. If it's raised again, it's active. Main runways often follow edges: walks, fences and beds. Lawns from Ames out to Ankeny and Urbandale show the same pattern. Look for fresh ridges and mounds after rain.
A year of moles in Ames.
- Winter: lows near 12°F in Ames. Ground freezes; moles go deep. - Spring: peak tunneling. Best time to trap. - Summer: highs near 84°F in Ames push moles deeper. - Fall: a second burst near the surface.
Mole, gopher or vole?
- Damage: moles don’t eat plants; gophers and voles do. - 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.
What works, and what doesn’t.
- Rarely alone: grub control, since they mostly eat earthworms. - Works: traps set in active runways. - Sometimes: labeled baits, used deep in tunnels. - Rarely: castor oil, sonic stakes, gum or flooding.
Protecting garden beds.
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. Bury quarter-inch hardware cloth around beds, about two feet deep.
Lawn care that helps.
Constantly wet lawns draw earthworms, and moles follow. Healthy turf recovers from tunnels faster. Grub control alone rarely moves moles on. Water deeply but less often.
Signs the problem is over.
- New ridges? Another mole may have moved in. - No new mounds for two weeks. - Stepped-down runways stay flat. - Traps stay untouched for several checks.
Choosing a trap.
- Rules: check what your state allows first. - 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.
Mole myths.
- Flooding tunnels: they just dig new ones. - 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.
Moles aren’t all bad.
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. Moles loosen and aerate soil.
Fixing the lawn afterward.
Rake mounds flat and step ridges down. Water to settle the soil. Overseed bare spots in spring or fall. Wait until the mole is caught.
Moles, kids and pets.
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. Moles don't bite unless handled.
What a mole visit looks like.
They test which runways are active. Traps go into the main runways. They check traps every day or two. The tech walks the lawn and maps the tunnels.
Moles, voles or gophers?
- Chipmunks: small clean holes with no soil around them. - Moles: raised ridges and round, volcano-shaped mounds. - Voles: narrow surface runways through the grass. - Gophers: crescent-shaped mounds with a plugged hole.
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.
- Is lawn repair included? - Is it a mole, gopher or vole? - Which method will you use? - How often will you check traps? - What if another mole moves in?
Moles by the numbers.
Across Ames, tunnels often run just under the surface, with deeper nesting chambers below, and a single mole can maintain an extensive system across a yard. Across Ames, because moles are solitary, several fresh ridges usually mean more than one animal. Across Ames, 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. Across Ames, 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
- Irrigation and drainage corrections.
- Soil type: rocky or clay ground slows trap sets.
- Provider type: wildlife operator versus lawn company.
- Single visit versus a multi-visit trapping plan.
- Per-mole pricing versus per-visit pricing.
- Access around fences, slopes, and dense plantings.

What bothers you most about moles?
When to call for help
A pro can usually catch the mole within a few visits. if you can't find an active runway. Call if new mounds keep appearing for more than a week.
What you can do yourself
Trapping yourself can work. Set the trap exactly as the instructions say. Skip sonic stakes, gum and flooding.
Moles in Ames
Ames gets about 36 inches of rain a year, so moles favor watered lawns and shady beds. Winter lows near 12°F in Ames freeze the ground, so moles go deeper until spring. In Ames's neighborhoods, irrigated lawns and garden beds are favorite spots.

Simple ways to keep moles away
- Edge beds with buried hardware cloth.
- Check for fresh mounds after rain.
- Act early in spring.
- Fix tunnels only after trapping.
- Skip sonic stakes and castor oil.

Moles can tunnel quickly through soft soil in soft soil
Mole fur lies flat both ways, allowing reverse travel
Questions people ask
How long does professional mole control take?
Usually one to three weeks of regular trap checks.
Will moles come back after they are removed?
New moles can move into empty tunnels. Catching newcomers early keeps damage small.
Why are moles in my yard but not my neighbor's?
Moist, loose soil full of earthworms draws them. Watered lawns and shady beds are favorites.
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.
What is the difference between mole and gopher damage?
Moles push up round, volcano-like mounds and raised ridges. Gophers leave crescent-shaped mounds with a plugged hole to one side.
Do ultrasonic mole repellers work?
No. Across Ames, there is no scientific evidence that ultrasonic or vibrating devices repel moles, and extension offices consistently advise against relying on them. Across Ames, moles have poor eyesight and live almost entirely underground, where airborne sound barely reaches them. Across Ames, if you try a sonic stake, watch for fresh ridges over two weeks; if activity continues, switch to traps in the active runs.
Do people hire professionals for mole removal?
Some do, and many try it themselves first. Across Ames, trapping in active runs is the method with the most consistent results, so a professional makes the most sense when tunnels keep reappearing after several weeks of trapping, or when you would rather not handle traps and dispose of animals yourself. Across Ames, ask about the number of visits and whether the follow-up is included.
When are moles most active in Ames?
Spring and fall, especially after rain. Frozen winter ground sends them deep.
Are moles common in Ames?
Yes.
