Anyone in Westminster trying to figure out what's digging up the yard.
What to look for
They push up fan-shaped mounds as they dig. Gophers eat roots, bulbs and plants from below. One gopher can ruin a garden bed in a few days.
- 1Fan-shaped dirt mounds.
- 2A plugged hole off to one side of the mound.
- 3Plants wilting or pulled underground.
- 4Chewed irrigation lines.
- 5Soft, sinking soil.
- 6Fresh mounds after rain or watering.
Why it’s worth acting soon

A rough guide only. Large lots and repeat visits cost more.
Treatment options and typical costs
Activity Mapping and Tunnel Probing
$75–$200
A provider in Westminster will usually rake or flatten every mound first, then return to see which ones reappear. Fresh soil tells them exactly where the animal is still digging.
- Time
- 45–90 minutes
- Best for
- Every job; separates fresh activity from old, abandoned mounds
Burrow Fumigation
$200–$600 per treatment
Because fumigation is invisible, follow-up matters even more than with trapping. A pro should come back to check for fresh mounds.
- Time
- 1–2 hours, with re-entry restrictions
- Best for
- Heavy activity on large lots, away from structures, where legal
Exclusion and Follow-Up Monitoring
$200–$1,500 depending on scope
Ask what a service plan in Westminster covers, how often visits happen, and whether traps stay in place between them. A clear plan turns gopher control into a manageable chore.
- Time
- Half a day for barriers; monitoring visits 20–40 minutes
- Best for
- Gardens, raised beds, young trees, and properties near open fields
Trapping in Active Tunnels
$150–$450 per visit series
A good trapping series in Westminster includes rechecks every day or two until mounds stop appearing. Empty traps get moved to fresher activity, not left in place.
- Time
- 2–5 visits over 1–2 weeks
- Best for
- Small yards, gardens, homes with pets, and anyone avoiding poison

Which gophers live around Westminster.
Pocket gophers are stocky, with cheek pouches and long claws. They live alone, so a yard usually has one or two. Voles may also be at work; they leave surface runways.
Gopher mounds are fan-shaped, with a plugged hole off to one side.When they dig.
Digging peaks in spring and fall, when soil is moist. Frozen ground slows surface work in winter. Summer heat and dry soil push activity deeper.
Finding the main tunnel.
Find a fresh, fan-shaped mound. The plugged hole is on the open side of the fan. Probe a foot or two back to find the main tunnel. That's where traps belong. Yards from Westminster out to Arvada and Thornton share the same pattern.
A year of digging in Westminster.
- Fall: a second peak before winter. - Winter: lows near 19°F in Westminster. Surface work slows. - Spring: peak digging as soil warms and stays moist. - Summer: highs near 89°F in Westminster push activity deeper.
Gopher, mole or vole?
- Vole: surface runways and chewed plant stems. - Chipmunk: neat holes, no dirt pile. - Gopher: fan-shaped mounds, plugged hole to one side. - Mole: round mounds and raised ridges.
Protecting gardens and trees.
- Bulbs: use small wire cages. - Drip lines: check for chew marks each spring. - Raised beds: line the bottom with hardware cloth. - Trees: plant in wire root baskets.
What works, and what doesn’t.
- Rarely: sonic stakes, gum, castor oil or flooding. - Rarely: plants said to repel gophers. - Works: traps in the main tunnel. - Sometimes: labeled baits placed deep in tunnels.
How gopher traps are set.
- Set: place a trap facing each way. - Cover: block light with a board or sod. - Check: look again within a day. - Find: probe near a fresh mound for the main tunnel. - Open: dig down to expose both directions.
Lawn care that discourages diggers.
Water deeply but less often. Keep weedy edges and tall grass mowed. Pull mulch back from tree trunks. Healthy turf recovers from digging faster.
Fixing the yard afterward.
Wait until the digging stops. Rake mounds flat and fill sunken tunnels. Water to settle the soil. Reseed or patch bare spots in spring or fall.
Irrigation lines and sprinklers.
Gophers chew drip lines and sprinkler tubing. Check for wet spots or weak spray each spring. Bury lines a little deeper where you can. Fix leaks fast, since damp soil draws more digging.
Natural help.
Owls, hawks, snakes and foxes all hunt gophers and voles. Barn owl boxes can help on bigger properties. Bait can harm pets and wildlife if misused. Traps avoid that risk.
Myths about yard diggers.
- Sonic stakes: animals get used to them. - Repellent plants: little proof of results. - Many mounds, many animals: often it’s one. - Gum or laxatives: no evidence they work. - Car exhaust or flooding: unsafe and unreliable.
Signs the problem is over.
- Flattened mounds stay flat. - New mounds later? Another one moved in. - No fresh mounds for two weeks. - Plants stop wilting or disappearing.
Underground wire baskets.
Plant new trees, roses and bulbs in baskets of galvanized wire. Leave a few inches of wire above the soil. Baskets last several years, long enough for roots to get established.
Raised beds that stay safe.
- Edges: run the wire up the inside walls. - Soil: fill after the wire is in place. - Base: staple hardware cloth across the bottom. - Wire: half-inch mesh, not chicken wire.
When a whole street has them.
Diggers move in from vacant lots, fields and neighbors' yards. Clearing your yard alone may only last a season. Talking with neighbors and treating at the same time works better.
Pets, kids and digging.
Keep kids and pets away from traps and bait. Choose traps over bait if a dog likes to dig. Fill old mounds so no one twists an ankle.
Gopher-proofing new landscaping.
Lay wire mesh under new sod before it goes down. Plant shrubs and trees in wire baskets. Raised beds with mesh bottoms protect vegetables. It costs more up front but saves replanting.
Questions to ask before you sign.
- How often will you check? - What if another one moves in? - Is it safe around pets? - Is it a gopher, mole or vole? - Which method will you use?
Ways to keep the cost down.
- Protect beds and trees with wire. - Confirm what’s digging before paying for treatment. - Trap early, when there’s just one.
How to size up the yard damage.
For Westminster homes, because each gopher is solitary, a yard with several fresh mounds usually means several animals, each with its own network. For Westminster homes, count the active mounds during your walk-through — that number, not a national average, is what should drive a treatment plan. For Westminster homes, 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. For Westminster homes, tunnel systems typically run 6 to 12 inches below the surface, with deeper nesting and food-storage chambers.
What affects the price
- Pets or children requiring toxicant-free methods.
- Trapping versus baiting versus fumigation.
- Soil type, since dry or sandy ground limits fumigants.
- Need for soil fill or hardscape repair afterward.
- Lot size and total ground the provider must cover.
- Travel distance from the provider to the property.
- Number of fresh mounds and active tunnel systems.
- Documentation requirements for HOAs or property managers.

What's digging in your yard?
When to call for help
for big lots next to fields. Call if new mounds keep appearing after a week of trapping. A pro can find the main tunnels fast.
What you can do yourself
Find the right tunnel and follow the trap instructions. Skip sonic stakes and home remedies. Once you know what it is, trapping is DIY-friendly.
Gophers in Westminster
Winter lows near 19°F freeze the topsoil around Westminster, but tunnels below keep going. In Westminster's neighborhoods, lawns and vegetable gardens next to open lots are hot spots. Westminster only gets about 16 inches of rain a year, so watered lawns and gardens draw most of the digging.
Gopher tips from the experts
Fresh mounds tell the story
Around Westminster, Colorado, 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 Colorado, 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.
