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 New Brunswick 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 New Brunswick 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.

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
The flattening test is simple: press, mark, recheck in 24 hours. Tunnels reopened overnight are active and become the trap sites for the New Brunswick job. Mounds get noted too, since they mark deeper tunnels below New Brunswick lawns.
- Time
- 45–90 minutes
- Best for
- Every job; trapping fails without it
Follow-Up Monitoring
$50–$150 per visit; often included in plans
Some New Brunswick providers offer seasonal monitoring for properties that border open land. It is priced per visit or as a yearly plan. For New Brunswick 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
Moles follow food and soft soil, so overwatered lawns in New Brunswick attract them. Less water, better drainage, and firmer soil discourage them. It will not remove a mole already in a New Brunswick lawn, but it lowers repeat visits.
- 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 New Brunswick providers run the flattening test before any bait goes down. Bait in a dead tunnel in New Brunswick 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 New Brunswick.
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 New Brunswick. It's gray, about six inches long, with big spade-like front feet. Star-nosed moles favor wet spots here.
When they tunnel.
Frozen ground in winter sends them deeper. Summer heat and drought also push them down.
Raised ridges are feeding tunnels just under the turf. Many are used once and abandoned.Finding an active tunnel.
If it's raised again, it's active. Main runways often follow edges: walks, fences and beds. Lawns from New Brunswick out to Edison and Woodbridge show the same pattern. Look for fresh ridges and mounds after rain. Step down a short stretch of tunnel and mark it. Check it in a day or two.
A year of moles in New Brunswick.
- Summer: highs near 86°F in New Brunswick push moles deeper. - Fall: a second burst near the surface. - Winter: lows near 25°F in New Brunswick. Ground freezes; moles go deep. - Spring: peak tunneling. Best time to trap.
Mole, gopher or vole?
- 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. - Mole: raised ridges and round, volcano-like mounds.
What works, and what doesn’t.
- Sometimes: labeled baits, used deep in tunnels. - Rarely: castor oil, sonic stakes, gum or flooding. - Rarely alone: grub control, since they mostly eat earthworms. - Works: traps set in active runways.
Protecting garden beds.
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. Bend the bottom edge outward.
Lawn care that helps.
Healthy turf recovers from tunnels faster. Grub control alone rarely moves moles on. Water deeply but less often. Constantly wet lawns draw earthworms, and moles follow.
Signs the problem is over.
- Stepped-down runways stay flat. - Traps stay untouched for several checks. - New ridges? Another mole may have moved in. - No new mounds for two weeks.
Choosing a trap.
- 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. - Scissor traps: set straddling an active runway.
Mole myths.
- 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. - Chewing gum in tunnels: no evidence it works.
Moles aren’t all bad.
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. They eat grubs and other insect larvae.
Fixing the lawn afterward.
Water to settle the soil. Overseed bare spots in spring or fall. Wait until the mole is caught. Rake mounds flat and step ridges down.
Moles, kids and pets.
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. Keep kids and pets away from traps.
What a mole visit looks like.
Traps go into the main runways. They check traps every day or two. The tech walks the lawn and maps the tunnels. They test which runways are active.
Moles, voles or gophers?
- Voles: narrow surface runways through the grass. - Gophers: crescent-shaped mounds with a plugged hole. - Chipmunks: small clean holes with no soil around them. - Moles: raised ridges and round, volcano-shaped mounds.
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.
- Which method will you use? - How often will you check traps? - What if another mole moves in? - Is lawn repair included? - Is it a mole, gopher or vole?
Moles by the numbers.
For New Brunswick homes, because moles are solitary, several fresh ridges usually mean more than one animal. For New Brunswick homes, 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. For New Brunswick homes, moles do not eat plants; they tunnel for earthworms, grubs, and soil insects, and the ridges they leave behind are what most people notice. For New Brunswick homes, tunnels often run just under the surface, with deeper nesting chambers below, and a single mole can maintain an extensive system across a yard.
What affects the price
- Property bordering fields, woods, or streams.
- Number of follow-up rechecks included.
- Per-mole pricing versus per-visit pricing.
- Single visit versus a multi-visit trapping plan.
- Soil type: rocky or clay ground slows trap sets.
- Season, since spring and fall book fastest.

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
Skip sonic stakes, gum and flooding. Set the trap exactly as the instructions say. Trapping yourself can work.
Moles in New Brunswick

Questions people ask
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.
What kind of traps do professionals use?
Usually scissor or harpoon traps set in active runways. They're the most reliable method.
Why do repellents and sonic stakes not work on moles?
Moles get used to them or tunnel around them. Studies show little lasting effect.
When is the best time to trap moles?
Spring and fall, when they're tunneling near the surface. Right after rain is ideal.
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 mole exterminators charge per mole?
Some do. For New Brunswick homes, per-animal pricing means the bill scales with how many are caught, while a flat-rate program covers the whole job regardless. For New Brunswick homes, ask which structure the provider uses, since the two can produce very different totals.
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.
When are moles most active in New Brunswick?
Spring and fall, especially after rain. Frozen winter ground sends them deep.
Are moles common in New Brunswick?
Yes.
