Anyone in Broomfield trying to figure out what's digging up the yard.
What to look for
Gophers eat roots, bulbs and plants from below. They push up fan-shaped mounds as they dig. 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
- Roots, bulbs and young trees get eaten.
- Irrigation lines get chewed.
- Mounds dull mower blades.
- More gophers move into empty tunnels.
Treatment options and typical costs
Activity Mapping and Tunnel Probing
$75–$200
Fresh mounds, plugged feed holes, and clipped plants get logged on a simple property map before any control starts in Broomfield. That record is the baseline for judging when work is done.
- Time
- 45–90 minutes
- Best for
- Every job; separates fresh activity from old, abandoned mounds
Labeled Burrow Baiting
$150–$400 per treatment
Baits work well on large Broomfield acreage, pastures, and orchards where the mound count makes trapping impractical. On a typical suburban lot, most pros still trap first.
- Time
- 30–60 minutes per visit, plus follow-up
- Best for
- Larger properties and heavy infestations where trapping alone is too slow
Trapping in Active Tunnels
$150–$450 per visit series
A good trapping series in Broomfield 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
Exclusion and Follow-Up Monitoring
$200–$1,500 depending on scope
Ask what a service plan in Broomfield 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

Gophers eat roots from below. Plants that wilt and lift out easily are a classic sign.Which gophers live around Broomfield.
They live alone, so a yard usually has one or two. Pocket gophers are stocky, with cheek pouches and long claws. Voles may also be at work; they leave surface runways.
When they dig.
Frozen ground slows surface work in winter. Digging peaks in spring and fall, when soil is moist. Summer heat and dry soil push activity deeper.
Gopher mounds are fan-shaped, with a plugged hole off to one side.Finding the main tunnel.
Probe a foot or two back to find the main tunnel. That's where traps belong. Yards from Broomfield out to Westminster and Arvada share the same pattern. Find a fresh, fan-shaped mound. The plugged hole is on the open side of the fan.
A year of digging in Broomfield.
- Fall: a second peak before winter. - Summer: highs near 88°F in Broomfield push activity deeper. - Spring: peak digging as soil warms and stays moist. - Winter: lows near 18°F in Broomfield. Surface work slows.
Gopher, mole or vole?
- Vole: surface runways and chewed plant stems. - Mole: round mounds and raised ridges. - Gopher: fan-shaped mounds, plugged hole to one side. - Chipmunk: neat holes, no dirt pile.
Protecting gardens and trees.
- Bulbs: use small wire cages. - Trees: plant in wire root baskets. - Raised beds: line the bottom with hardware cloth. - Drip lines: check for chew marks each spring.
What works, and what doesn’t.
- Rarely: sonic stakes, gum, castor oil or flooding. - Sometimes: labeled baits placed deep in tunnels. - Works: traps in the main tunnel. - Rarely: plants said to repel gophers.
How gopher traps are set.
- Cover: block light with a board or sod. - Set: place a trap facing each way. - Open: dig down to expose both directions. - Find: probe near a fresh mound for the main tunnel. - Check: look again within a day.
Lawn care that discourages diggers.
Keep weedy edges and tall grass mowed. Water deeply but less often. Healthy turf recovers from digging faster. Pull mulch back from tree trunks.
Fixing the yard afterward.
Rake mounds flat and fill sunken tunnels. Wait until the digging stops. Reseed or patch bare spots in spring or fall. Water to settle the soil.
Irrigation lines and sprinklers.
Check for wet spots or weak spray each spring. Gophers chew drip lines and sprinkler tubing. Fix leaks fast, since damp soil draws more digging. Bury lines a little deeper where you can.
Natural help.
Barn owl boxes can help on bigger properties. Owls, hawks, snakes and foxes all hunt gophers and voles. Traps avoid that risk. Bait can harm pets and wildlife if misused.
Myths about yard diggers.
- 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. - Many mounds, many animals: often it’s one.
Signs the problem is over.
- Flattened mounds stay flat. - Plants stop wilting or disappearing. - No fresh mounds for two weeks. - New mounds later? Another one moved in.
Underground wire baskets.
Leave a few inches of wire above the soil. Plant new trees, roses and bulbs in baskets of galvanized wire. Baskets last several years, long enough for roots to get established.
Raised beds that stay safe.
- Edges: run the wire up the inside walls. - Wire: half-inch mesh, not chicken wire. - Base: staple hardware cloth across the bottom. - Soil: fill after the wire is in place.
When a whole street has them.
Clearing your yard alone may only last a season. Diggers move in from vacant lots, fields and neighbors' yards. Talking with neighbors and treating at the same time works better.
Pets, kids and digging.
Choose traps over bait if a dog likes to dig. Keep kids and pets away from traps and bait. Fill old mounds so no one twists an ankle.
Gopher-proofing new landscaping.
Plant shrubs and trees in wire baskets. Lay wire mesh under new sod before it goes down. It costs more up front but saves replanting. Raised beds with mesh bottoms protect vegetables.
Questions to ask before you sign.
- What if another one moves in? - How often will you check? - Which method will you use? - Is it a gopher, mole or vole? - Is it safe around pets?
How to size up the yard damage.
For Broomfield homes, because each gopher is solitary, a yard with several fresh mounds usually means several animals, each with its own network. For Broomfield homes, count the active mounds during your walk-through — that number, not a national average, is what should drive a treatment plan. For Broomfield 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 Broomfield homes, tunnel systems typically run 6 to 12 inches below the surface, with deeper nesting and food-storage chambers.
Gopher mounds vs. other lawn damage in Broomfield.
Around Broomfield, CO, 16 inches of rain a year softens the soil and makes new mounds more visible after a wet spell. For Broomfield homes, reading the shape of the mound is the first step in choosing the right control method. For Broomfield homes, gopher activity shows up as fan-shaped mounds of fresh soil with a plugged entrance off to one side. For Broomfield homes, the mounds are the giveaway — moles leave raised ridges without a clear entrance hole, and voles leave shallow surface runways through the grass.
What a gopher control job should cost in Broomfield.
For Broomfield homes, 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. For Broomfield homes, 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. For Broomfield homes, 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.
For Broomfield homes, 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. For Broomfield homes, 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. For Broomfield homes, 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
- How many recheck visits the plan includes.
- Pets or children requiring toxicant-free methods.
- Proximity of activity to buildings and hardscape.
- Season, with spring and fall needing more follow-up.
- One-time service versus a monthly monitoring plan.
- State restrictions on which baits can be used.

Gopher tips from the experts
Fresh mounds tell the story
Around Broomfield, 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.
