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.

Homeowners in Portsmouth 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 Portsmouth 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 Portsmouth, 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
Follow-Up Monitoring
$50–$150 per visit; often included in plans
Monitoring visits in Portsmouth are short but important. The provider rechecks flattened tunnels, looks for new mounds, and resets traps on any Portsmouth runway that reopened. Many Portsmouth plans include one or two of these visits by default.
- Time
- 20–30 minutes per visit
- Best for
- Every trapping job; confirms the yard is clear
Active-Runway Trapping
$150–$400 per visit; multi-visit plans $300–$900
Because a single mole can cover a large area, one yard in Portsmouth often holds only one or two animals. Trapping removes them one by one and confirms success. Most Portsmouth 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

Round, volcano-shaped mounds come from deeper mole tunnels. Gopher mounds are crescent-shaped with a plugged hole.Which moles live around Portsmouth.
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 Portsmouth.
When they tunnel.
Mild winters keep them near the surface. 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 Portsmouth out to Norfolk and Chesapeake show the same pattern. Look for fresh ridges and mounds after rain.
A year of moles in Portsmouth.
- Winter: mild in Portsmouth. Moles stay active. - Spring: peak tunneling. Best time to trap. - Summer: highs near 87°F in Portsmouth 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 Portsmouth, 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 Portsmouth, because moles are solitary, several fresh ridges usually mean more than one animal. Across Portsmouth, 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 Portsmouth, 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
- Single visit versus a multi-visit trapping plan.
- State rules that affect trap or bait choices.
- Buried barriers for raised beds or gardens.
- Property bordering fields, woods, or streams.
- Per-mole pricing versus per-visit pricing.
- Soil type: rocky or clay ground slows trap sets.

What bothers you most about moles?
When to call for help
if you can't find an active runway. A pro can usually catch the mole within a few visits. Call if new mounds keep appearing for more than a week.
What you can do yourself
Set the trap exactly as the instructions say. Skip sonic stakes, gum and flooding. Trapping yourself can work.
Moles in Portsmouth

Questions people ask
How long does professional mole control take?
Usually one to three weeks of regular trap checks.
Can I just flood the tunnels or fill them in?
It rarely works. Moles dig new tunnels or move a few feet away.
Will grub control get rid of moles?
Rarely. Earthworms are their main food. Killing grubs alone usually doesn't move them on.
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.
Should I repair the lawn before or after trapping?
After. Fixing it first hides the tunnels you need to find.
Is an annual mole control contract worth it?
It depends on how often moles return. Homeowners considering monthly service should weigh local quotes vary, so ask for a written estimate. It's a published estimate, not a local quote.
Do mole exterminators charge per mole?
Some do. Across Portsmouth, per-animal pricing means the bill scales with how many are caught, while a flat-rate program covers the whole job regardless. Across Portsmouth, ask which structure the provider uses, since the two can produce very different totals.
When are moles most active in Portsmouth?
Spring and fall, especially after rain. Mild winters keep some activity going year-round.
Are moles common in Portsmouth?
