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.
Homeowners in Dover 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 Dover 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
Good mole work is mostly finding the right tunnel. The provider maps the runway network in Dover, flags the active sections, and picks two or three trap points. That map also becomes the baseline for follow-up visits in Dover.
- Time
- 45–90 minutes
- Best for
- Every job; trapping fails without it
Follow-Up Monitoring
$50–$150 per visit; often included in plans
Some Dover providers offer seasonal monitoring for properties that border open land. It is priced per visit or as a yearly plan. For Dover homeowners with recurring moles, that is often cheaper than starting fresh each year.
- 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
Grub control is often sold as mole control, with real limits. Moles eat mostly earthworms, so a Dover lawn with no grubs can still host them. Across Dover, a provider should be honest that habitat work supports trapping rather than replacing it.
- Time
- 1–4 hours
- Best for
- Repeat problems; protecting beds and small areas
Mole-Labeled Baits
$100–$300 per application
Baits are not a shortcut; they only work in live tunnels. That is why Dover providers run the flattening test before any bait goes down. Bait in a dead tunnel in Dover is wasted product.
- 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.
Round, volcano-shaped mounds come from deeper mole tunnels. Gopher mounds are crescent-shaped with a plugged hole.Which moles live around Dover.
It's gray, about six inches long, with big spade-like front feet. Star-nosed moles favor wet spots here. Hairy-tailed moles prefer woods. Moles are insectivores, not rodents. They eat earthworms and grubs, not roots. The eastern mole is the one digging up lawns around Dover.
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 Dover out to Rochester and Portsmouth show the same pattern. Look for fresh ridges and mounds after rain.
A year of moles in Dover.
- Winter: lows near 15°F in Dover. Ground freezes; moles go deep. - Spring: peak tunneling. Best time to trap. - Summer: highs near 81°F in Dover 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 Dover, 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 Dover, because moles are solitary, several fresh ridges usually mean more than one animal. Across Dover, 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 Dover, 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 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
Trapping yourself can work. Set the trap exactly as the instructions say. Skip sonic stakes, gum and flooding.
Moles in Dover
With about 46 inches of rain a year, Dover keeps soil soft and full of earthworms, which moles love. Winter lows near 15°F in Dover freeze the ground, so moles go deeper until spring. In Dover's neighborhoods, irrigated lawns and garden beds are favorite spots.
Local research
Moles in Dover, NH: what the public record shows
Before you compare quotes, it helps to know which moles actually live in New Hampshire, when they are busiest around Dover, and what the state figures look like. Everything below links to the agency or university page it came from.
Mole species recorded in New Hampshire
- Star-nosed mole (Condylura cristata) — Northeast and Great Lakes; wet soils; up to 7 young.
- Hairy-tailed mole (Parascalops breweri) — Northeastern uplands.
When moles are busiest around Dover
Moles remain active all year; mounds appear right after snowmelt and activity subsides as the ground dries in late spring.
UNH Extension recommends trapping in an active runway as the only practical control, and says peaceful coexistence is often the best strategy since mole activity subsides as soil dries.

Questions people ask
Should I repair the lawn before or after trapping?
After. Fixing it first hides the tunnels you need to find.
What kind of traps do professionals use?
Usually scissor or harpoon traps set in active runways. They're the most reliable method.
Are mole baits safe around pets and children?
Use them only as the label directs, deep in tunnels. Traps are often the safer choice.
When is the best time to trap moles?
Spring and fall, when they're tunneling near the surface. Right after rain is ideal.
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.
Do ultrasonic mole repellers work?
No. Across Dover, there is no scientific evidence that ultrasonic or vibrating devices repel moles, and extension offices consistently advise against relying on them. Across Dover, moles have poor eyesight and live almost entirely underground, where airborne sound barely reaches them. Across Dover, if you try a sonic stake, watch for fresh ridges over two weeks; if activity continues, switch to traps in the active runs.
What is the most popular way to get rid of moles?
Across Dover, trapping is the method extension offices and professionals recommend most often, because it targets the mole itself rather than the insects it feeds on. Across Dover, set traps in the active runs, check them daily, and keep at it until fresh ridges stop appearing.
When are moles most active in Dover?
Spring and fall, especially after rain. Frozen winter ground sends them deep.
Are moles common in Dover?
Yes.
