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 Biddeford are busiest in spring and fall. They tunnel near the surface after rain. One mole can dig a lot of tunnel.

Why it’s worth acting soon

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 Biddeford, flags the active sections, and picks two or three trap points. That map also becomes the baseline for follow-up visits in Biddeford.
- Time
- 45–90 minutes
- Best for
- Every job; trapping fails without it
Follow-Up Monitoring
$50–$150 per visit; often included in plans
Some Biddeford providers offer seasonal monitoring for properties that border open land. It is priced per visit or as a yearly plan. For Biddeford 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 Biddeford lawn with no grubs can still host them. In Biddeford, 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 Biddeford providers run the flattening test before any bait goes down. Bait in a dead tunnel in Biddeford 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.
Hardware cloth buried around beds keeps moles out of the places you care about most.Which moles live around Biddeford.
The eastern mole is the one digging up lawns around Biddeford. 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.
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.
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. If it's raised again, it's active. Main runways often follow edges: walks, fences and beds. Lawns from Biddeford out to Saco and Scarborough show the same pattern.
A year of moles in Biddeford.
- Winter: lows near 14°F in Biddeford. Ground freezes; moles go deep. - Fall: a second burst near the surface. - Summer: highs near 79°F in Biddeford push moles deeper. - Spring: peak tunneling. Best time to trap.
Mole, gopher or vole?
- Damage: moles don’t eat plants; gophers and voles do. - Vole: surface runways and small holes in the grass. - Gopher: crescent-shaped mounds with a plugged hole. - Mole: raised ridges and round, volcano-like mounds.
What works, and what doesn’t.
- Rarely alone: grub control, since they mostly eat earthworms. - Rarely: castor oil, sonic stakes, gum or flooding. - Sometimes: labeled baits, used deep in tunnels. - Works: traps set in active runways.
Protecting garden beds.
It's work up front, but it lasts for years. Raised beds can get a mesh floor before you fill them. Bend the bottom edge outward. Bury quarter-inch hardware cloth around beds, about two feet deep.
Lawn care that helps.
Grub control alone rarely moves moles on. Healthy turf recovers from tunnels faster. Constantly wet lawns draw earthworms, and moles follow. Water deeply but less often.
Signs the problem is over.
- New ridges? Another mole may have moved in. - Traps stay untouched for several checks. - Stepped-down runways stay flat. - No new mounds for two weeks.
Choosing a trap.
- Rules: check what your state allows first. - Placement: main runways beat fresh feeding ridges. - Tunnel traps: sit inside a dug-out runway. - Harpoon traps: set on top of a pressed-down ridge. - Scissor traps: set straddling an active runway.
Mole myths.
- Flooding tunnels: they just dig new ones. - Many mounds, many moles: usually it’s one or two. - Moles eat bulbs: no, voles using their tunnels do. - Castor oil: may move them briefly, not away. - Chewing gum in tunnels: no evidence it works.
Moles aren’t all bad.
In a front lawn or garden, most people want them gone. A mole in a field may be fine to leave. They eat grubs and other insect larvae. Moles loosen and aerate soil.
Fixing the lawn afterward.
Overseed bare spots in spring or fall. Water to settle the soil. Rake mounds flat and step ridges down. Wait until the mole is caught.
Moles, kids and pets.
Digging dogs can wreck a lawn faster than moles. Baits must go deep in tunnels, exactly as the label says. Keep kids and pets away from traps. Moles don't bite unless handled.
What a mole visit looks like.
They check traps every day or two. Traps go into the main runways. They test which runways are active. The tech walks the lawn and maps the tunnels.
Moles, voles or gophers?
- Chipmunks: small clean holes with no soil around them. - Gophers: crescent-shaped mounds with a plugged hole. - Voles: narrow surface runways through the grass. - Moles: raised ridges and round, volcano-shaped mounds.
Watering and moles.
Fix leaky sprinklers that leave soggy corners. Water deeply and less often instead of a little every day. Moles follow moist soil, where worms rise near the surface.
Flower beds and borders.
Press tunnels down firmly and water to settle the soil. Plants wilt when their roots are left hanging in air pockets. Moles tunnel under beds looking for worms, not to eat plants.
Questions to ask before you sign.
- Is lawn repair included? - What if another mole moves in? - How often will you check traps? - Which method will you use? - Is it a mole, gopher or vole?
Moles by the numbers.
In Biddeford, moles do not eat plants; they tunnel for earthworms, grubs, and soil insects, and the ridges they leave behind are what most people notice. In Biddeford, tunnels often run just under the surface, with deeper nesting chambers below, and a single mole can maintain an extensive system across a yard. In Biddeford, because moles are solitary, several fresh ridges usually mean more than one animal. In Biddeford, 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.
What affects the price
- Property bordering fields, woods, or streams.
- Seasonal monitoring plans versus one-time service.
- Travel distance to rural properties.
- Number of follow-up rechecks included.
- Mole-labeled bait applications added to trapping.
- Soil type: rocky or clay ground slows trap sets.

Questions people ask
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.
What kind of traps do professionals use?
Usually scissor or harpoon traps set in active runways. They're the most reliable method.
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 I need a permit to trap moles?
Rules vary by state. Ask a local company what's allowed in Maine.
