Treatment options and typical costs
Activity Mapping and Tunnel Probing
$75–$200
A pro probes near fresh mounds to find the main tunnel. On a Longmont lawn or orchard this is the step that tells trapping and baiting where to go.
- Time
- 45–90 minutes
- Best for
- Every job; separates fresh activity from old, abandoned mounds
Trapping in Active Tunnels
$150–$450 per visit series
Set correctly in a main tunnel, traps often catch within days. Set in a lateral or old tunnel, they sit empty, which is why Longmont pros spend so much time probing first.
- 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
A gopher-proof bed in Longmont uses half-inch or smaller galvanized mesh laid across the bottom before soil goes in. Buried perimeter fencing with a surface lip helps in smaller gardens.
- 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
Tunnel-placed bait is far less risky to pets and wildlife than surface bait, but a Longmont homeowner should still treat it seriously. Ask any Longmont provider what they use and what the label says about dogs, cats, and children.
- Time
- 30–60 minutes per visit, plus follow-up
- Best for
- Larger properties and heavy infestations where trapping alone is too slow

Which gophers live around Longmont.
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.
Yards from Longmont out to Boulder and Loveland share the same pattern. 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.
A year of digging in Longmont.
- Spring: peak digging as soil warms and stays moist. - Summer: highs near 88°F in Longmont push activity deeper. - Fall: a second peak before winter. - Winter: lows near 16°F in Longmont. Surface work slows.
Gopher, mole or vole?
- Gopher: fan-shaped mounds, plugged hole to one side. - Mole: round mounds and raised ridges. - Vole: surface runways and chewed plant stems. - Chipmunk: neat holes, no dirt pile.
Protecting gardens and trees.
- Raised beds: line the bottom with hardware cloth. - Trees: plant in wire root baskets. - Bulbs: use small wire cages. - Drip lines: check for chew marks each spring.
What works, and what doesn’t.
- Works: traps in the main tunnel. - Sometimes: labeled baits placed deep in tunnels. - Rarely: sonic stakes, gum, castor oil or flooding. - Rarely: plants said to repel gophers.
How gopher traps are set.
- Find: probe near a fresh mound for the main tunnel. - Open: dig down to expose both directions. - Set: place a trap facing each way. - Cover: block light with a board or sod. - Check: look again within a day.
Lawn care that discourages diggers.
Healthy turf recovers from digging faster. Water deeply but less often. Keep weedy edges and tall grass mowed. Pull mulch back from tree trunks.
Fixing the yard afterward.
Reseed or patch bare spots in spring or fall. Wait until the digging stops. Rake mounds flat and fill sunken tunnels. Water to settle the soil.
Irrigation lines and sprinklers.
Fix leaks fast, since damp soil draws more digging. Gophers chew drip lines and sprinkler tubing. Check for wet spots or weak spray each spring. Bury lines a little deeper where you can.
Natural help.
Traps avoid that risk. 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.
Myths about yard diggers.
- Gum or laxatives: no evidence they work. - Car exhaust or flooding: unsafe and unreliable. - Sonic stakes: animals get used to them. - Repellent plants: little proof of results. - Many mounds, many animals: often it’s one.
Signs the problem is over.
- No fresh mounds for two weeks. - Plants stop wilting or disappearing. - Flattened mounds stay flat. - New mounds later? Another one moved in.
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.
- Base: staple hardware cloth across the bottom. - Wire: half-inch mesh, not chicken wire. - Edges: run the wire up the inside walls. - Soil: fill after the wire is in place.
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.
It costs more up front but saves replanting. Lay wire mesh under new sod before it goes down. Plant shrubs and trees in wire baskets. Raised beds with mesh bottoms protect vegetables.
Questions to ask before you sign.
- Is it a gopher, mole or vole? - Which method will you use? - How often will you check? - What if another one moves in? - Is it safe around pets?
Ways to keep the cost down.
- Confirm what’s digging before paying for treatment. - Trap early, when there’s just one. - Protect beds and trees with wire.
How to size up the yard damage.
Across Longmont, tunnel systems typically run 6 to 12 inches below the surface, with deeper nesting and food-storage chambers. Across Longmont, because each gopher is solitary, a yard with several fresh mounds usually means several animals, each with its own network. Across Longmont, count the active mounds during your walk-through — that number, not a national average, is what should drive a treatment plan. Across Longmont, 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.
What affects the price
- Need for soil fill or hardscape repair afterward.
- Proximity of activity to buildings and hardscape.
- Trapping versus baiting versus fumigation.
- Pets or children requiring toxicant-free methods.
- How many recheck visits the plan includes.
- Access difficulty, slopes, and dense plantings.
- Soil type, since dry or sandy ground limits fumigants.
- Number of fresh mounds and active tunnel systems.

When to call for help
for big lots next to fields. A pro can find the main tunnels fast. Call if new mounds keep appearing after a week of trapping.
What you can do yourself
Skip sonic stakes and home remedies. Once you know what it is, trapping is DIY-friendly. Find the right tunnel and follow the trap instructions.
Gophers in Longmont
Winter lows near 16°F freeze the topsoil around Longmont, but tunnels below keep going. In Longmont's neighborhoods, lawns and vegetable gardens next to open lots are hot spots. Longmont only gets about 14 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 Longmont, 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.

Questions people ask
Why do gopher quotes vary so much between providers?
Different methods, lot sizes and visit counts.
Is trapping or baiting cheaper?
Baiting can cost less up front. Trapping confirms the catch.

Can I trap gophers myself?
Yes. Set traps in the main tunnel near a fresh mound.
Is a gopher control contract worth it?
Across Longmont, a seasonal contract often costs little more than a single visit while covering the peak activity months. Across Longmont, compare what each plan includes and ask whether follow-up visits are covered before you commit. It can be, if the animal keeps coming back.
