What to look for
Gophers get blamed for a lot of digging. Around Londonderry, it's almost always something else. Moles push up round mounds and ridges. Voles chew runways through the grass and eat plants.

- The wrong treatment wastes money.
Treatment options and typical costs
Activity Mapping and Tunnel Probing
$75–$200
Control starts with a walk of the whole Londonderry property to flag fresh mounds and probe for the main runway that feeds them. Weathered mounds get ignored; fresh, moist soil marks live tunnels.
- Time
- 45–90 minutes
- Best for
- Every job; separates fresh activity from old, abandoned mounds
Exclusion and Follow-Up Monitoring
$200–$1,500 depending on scope
Properties in Londonderry that border pastures, canals, parks, or vacant lots tend to get recolonized within a season. A scheduled plan is often cheaper than repeated one-off calls.
- Time
- Half a day for barriers; monitoring visits 20–40 minutes
- Best for
- Gardens, raised beds, young trees, and properties near open fields
Labeled Burrow Baiting
$150–$400 per treatment
A bait job should include a return visit. Open bait spots get closed. Bait placed and never rechecked is why many problems linger.
- Time
- 30–60 minutes per visit, plus follow-up
- Best for
- Larger properties and heavy infestations where trapping alone is too slow
Burrow Fumigation
$200–$600 per treatment
Aluminum phosphide fumigants are restricted-use everywhere and require certified applicators. Gas cartridges are sold to homeowners in many areas. Local limits vary.
- Time
- 1–2 hours, with re-entry restrictions
- Best for
- Heavy activity on large lots, away from structures, where legal

Hardware cloth under raised beds keeps gophers away from the plants you care about.What's really digging around Londonderry.
Getting the ID right in Londonderry saves money and time. Chipmunks dig neat holes near patios and walls. Meadow and pine voles eat plants and leave narrow runways. Eastern moles cause most lawn tunnels here.
When they dig.
Summer heat and dry soil push activity deeper. Frozen ground slows surface work in winter. Digging peaks in spring and fall, when soil is moist.
Pocket gophers are stocky, with cheek pouches and long front claws. Each one lives alone.Telling the diggers apart.
Yards from Londonderry out to Derry and Hudson share the same pattern. Neat holes with no dirt pile often mean chipmunks. Narrow runways in the grass mean voles. Round and volcano-like means a mole. Look at the mound shape first.
A year of digging in Londonderry.
- Winter: lows near 15°F in Londonderry. Surface work slows. - Fall: a second peak before winter. - Summer: highs near 82°F in Londonderry push activity deeper. - Spring: peak digging as soil warms and stays moist.
Gopher, mole or vole?
- Chipmunk: neat holes, no dirt pile. - Vole: surface runways and chewed plant stems. - Mole: round mounds and raised ridges. - Gopher: fan-shaped mounds, plugged hole to one side.
Protecting gardens and trees.
- Drip lines: check for chew marks each spring. - Bulbs: use small wire cages. - Trees: plant in wire root baskets. - Raised beds: line the bottom with hardware cloth.
What works, and what doesn’t.
- Rarely: plants said to repel gophers. - Rarely: sonic stakes, gum, castor oil or flooding. - Sometimes: labeled baits placed deep in tunnels. - Works: traps in the main tunnel.
What helps with moles, voles and chipmunks.
- Skip: poisons near pets and wildlife. - All three: wire mesh under beds and around bulbs. - Chipmunks: seal gaps under patios and steps. - Voles: mow tall grass and clear mulch from plant stems. - Moles: traps set in active runways.
Lawn care that discourages diggers.
Healthy turf recovers from digging faster. Pull mulch back from tree trunks. Keep weedy edges and tall grass mowed. Water deeply but less often.
Fixing the yard afterward.
Reseed or patch bare spots in spring or fall. Water to settle the soil. Rake mounds flat and fill sunken tunnels. Wait until the digging stops.
Irrigation lines and sprinklers.
Fix leaks fast, since damp soil draws more digging. Bury lines a little deeper where you can. Check for wet spots or weak spray each spring. Gophers chew drip lines and sprinkler tubing.
Natural help.
Traps avoid that risk. Bait can harm pets and wildlife if misused. Barn owl boxes can help on bigger properties. Owls, hawks, snakes and foxes all hunt gophers and voles.
Myths about yard diggers.
- Many mounds, many animals: often it’s one. - Repellent plants: little proof of results. - Sonic stakes: animals get used to them. - Car exhaust or flooding: unsafe and unreliable. - Gum or laxatives: no evidence they work.
Signs the problem is over.
- New mounds later? Another one moved in. - Flattened mounds stay flat. - Plants stop wilting or disappearing. - No fresh mounds for two weeks.
Underground wire baskets.
Baskets last several years, long enough for roots to get established. Leave a few inches of wire above the soil. Plant new trees, roses and bulbs in baskets of galvanized wire.
Raised beds that stay safe.
- Soil: fill after the wire is in place. - Edges: run the wire up the inside walls. - Wire: half-inch mesh, not chicken wire. - Base: staple hardware cloth across the bottom.
When a whole street has them.
Talking with neighbors and treating at the same time works better. Clearing your yard alone may only last a season. Diggers move in from vacant lots, fields and neighbors' yards.
Pets, kids and digging.
Fill old mounds so no one twists an ankle. Choose traps over bait if a dog likes to dig. Keep kids and pets away from traps and bait.
Gopher-proofing new landscaping.
It costs more up front but saves replanting. Raised beds with mesh bottoms protect vegetables. Plant shrubs and trees in wire baskets. Lay wire mesh under new sod before it goes down.
Questions to ask before you sign.
- Is it safe around pets? - What if another one moves in? - How often will you check? - Which method will you use? - Is it a gopher, mole or vole?
How to size up the yard damage.
Around Londonderry, count the active mounds during your walk-through — that number, not a national average, is what should drive a treatment plan. Around Londonderry, because each gopher is solitary, a yard with several fresh mounds usually means several animals, each with its own network. Around Londonderry, tunnel systems typically run 6 to 12 inches below the surface, with deeper nesting and food-storage chambers. Around Londonderry, state wildlife agencies put a single pocket gopher at roughly a ton of soil moved per year, and mounds are the first thing most people notice.
Gopher mounds vs. other lawn damage in Londonderry.
Around Londonderry, reading the shape of the mound is the first step in choosing the right control method. Around Londonderry, NH, 44 inches of rain a year softens the soil and makes new mounds more visible after a wet spell. Around Londonderry, the mounds are the giveaway — moles leave raised ridges without a clear entrance hole, and voles leave shallow surface runways through the grass. Around Londonderry, gopher activity shows up as fan-shaped mounds of fresh soil with a plugged entrance off to one side.
What a gopher control job should cost in Londonderry.
Around Londonderry, ask for a written quote that spells out the number of visits, the method, and what the follow-up covers, rather than a single flat number. Around Londonderry, a small yard with one or two active tunnels is a small job; a large lot with tunneling across a wide area costs more because it takes more traps and more return visits. Around Londonderry, gopher control is priced by how many active tunnels there are and how much ground the animal is using, not by how many animals you can count.
Why gopher problems come back after removal.
Around Londonderry, the long-term fix pairs removal with habitat changes, like limiting the grubs and earthworms or irrigated plantings gophers feed on and keeping nearby overgrown areas trimmed, so your yard stops being the easiest target on the block. Around Londonderry, that is why removal alone rarely holds: if the food and the tunnel access are still there, a new gopher will simply re-colonize the same tunnels. Around Londonderry, gophers are solitary, but the space they leave is quickly filled by the next animal that moves in from neighboring yards or open ground.
What affects the price
- Number of fresh mounds and active tunnel systems.
- Need for soil fill or hardscape repair afterward.
- Whether wire baskets or buried mesh are requested.
- How many recheck visits the plan includes.
- State restrictions on which baits can be used.
- Documentation requirements for HOAs or property managers.

Gopher tips from the experts
Fresh mounds tell the story
Around Londonderry, New Hampshire, fresh, dark soil means a gopher is active now. Look at the mound shape, the plugged hole and any wilting plants before deciding what you have.
Gopher, mole or ground squirrel?
Gopher mounds are crescent or horseshoe shaped, with a plugged hole off to one side. Mole mounds are rounder, often with raised ridges nearby. Ground squirrel holes stay open, with no mound.
UC IPM: pocket gophersWhat they damage
Gophers chew roots, irrigation lines and sometimes buried cables. Fresh, moist soil means they’re active now. Keep watching after treatment, since a quiet yard doesn’t always mean they’re gone.
Utah State University Extension: pocket gophersSoil ropes after the snow melts
In snowy parts of New Hampshire, gophers tunnel through the snow and pack the tunnels with soil. When it melts, those soil ropes are left on the lawn. They show where gophers were busy over winter.
