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. Gophers and voles here are busiest in spring and fall. One mole can dig a lot of tunnel.

Treatment options and typical costs
Runway Identification and Activity Survey
$75–$200
A provider in Longmont starts by walking the lawn and separating active runways from exploratory tunnels. Surface ridges get pressed flat and checked the next day. The ones that pop back up are the tunnels worth treating in Longmont.
- Time
- 45–90 minutes
- Best for
- Every job; trapping fails without it
Follow-Up Monitoring
$50–$150 per visit; often included in plans
Monitoring visits in Longmont are short but important. The provider rechecks flattened tunnels, looks for new mounds, and resets traps on any Longmont runway that reopened. Many Longmont plans include one or two of these visits by default.
- Time
- 20–30 minutes per visit
- Best for
- Every trapping job; confirms the yard is clear
Mole-Labeled Baits
$100–$300 per application
Some Longmont providers prefer baits when soil is too rocky for clean trap sets. The worm-shaped formulations are placed by hand in runways using gloves. Afterward, activity in Longmont is monitored to confirm the tunnels have gone quiet.
- Time
- 30–45 minutes
- Best for
- Large or hard-to-trap areas; used exactly as labeled
Lawn, Moisture, and Bed Exclusion Work
$150–$450 depending on scope
Yards next to woods, fields or creeks keep getting new moles. Exclusion barriers protect the beds that matter most in Longmont while the open lawn is managed by trapping. This mix gives Longmont homeowners a realistic long-term plan.
- Time
- 1–4 hours
- Best for
- Repeat problems; protecting beds and small areas

Which moles live around Longmont.
Both eat plants, so treatment differs from mole trapping. Shallow runways through the grass point to voles. If the mounds around Longmont are crescent-shaped, it's a gopher. Voles leave surface runways in the grass. Pocket gophers eat roots and leave crescent-shaped mounds. Most lawn tunnels and mounds here are pocket gophers or voles. True moles are uncommon around Longmont.
Moles have big, spade-like front feet built for digging. They eat earthworms and grubs, not plants.When they tunnel.
Frozen ground in winter sends them deeper. Summer heat and drought also push them down.
Finding an active tunnel.
Lawns from Longmont out to Boulder and Loveland show the same pattern. Main runways often follow edges: walks, fences and beds. If it's raised again, it's active. Check it in a day or two. Step down a short stretch of tunnel and mark it. Look for fresh ridges and mounds after rain.
A year of moles in Longmont.
- Spring: peak tunneling. Best time to trap. - Summer: highs near 88°F in Longmont push moles deeper. - Fall: a second burst near the surface. - Winter: lows near 16°F in Longmont. Ground freezes; moles go deep.
Mole, gopher or vole?
- Mole: raised ridges and round, volcano-like mounds. - Gopher: crescent-shaped mounds with a plugged hole. - Vole: surface runways and small holes in the grass. - Damage: moles don’t eat plants; gophers and voles do.
What works, and what doesn’t.
- Works: traps set in active runways. - Sometimes: labeled baits, used deep in tunnels. - Rarely: castor oil, sonic stakes, gum or flooding. - Rarely alone: grub control, since they mostly eat earthworms.
Protecting garden beds.
Bury quarter-inch hardware cloth around beds, about two feet deep. Bend the bottom edge outward. Raised beds can get a mesh floor before you fill them. It's work up front, but it lasts for years.
Lawn care that helps.
Water deeply but less often. Constantly wet lawns draw earthworms, and moles follow. Healthy turf recovers from tunnels faster. Grub control alone rarely moves moles on.
Signs the problem is over.
- No new mounds for two weeks. - Stepped-down runways stay flat. - Traps stay untouched for several checks. - New ridges? Another mole may have moved in.
Choosing a trap.
- Scissor traps: set straddling an active runway. - Harpoon traps: set on top of a pressed-down ridge. - Tunnel traps: sit inside a dug-out runway. - Placement: main runways beat fresh feeding ridges. - Rules: check what your state allows first.
Mole myths.
- Chewing gum in tunnels: no evidence it works. - Castor oil: may move them briefly, not away. - Moles eat bulbs: no, voles using their tunnels do. - Many mounds, many moles: usually it’s one or two. - Flooding tunnels: they just dig new ones.
Moles aren’t all bad.
Moles loosen and aerate soil. They eat grubs and other insect larvae. A mole in a field may be fine to leave. In a front lawn or garden, most people want them gone.
Fixing the lawn afterward.
Wait until the mole is caught. Rake mounds flat and step ridges down. Water to settle the soil. Overseed bare spots in spring or fall.
Moles, kids and pets.
Moles don't bite unless handled. Keep kids and pets away from traps. Baits must go deep in tunnels, exactly as the label says. Digging dogs can wreck a lawn faster than moles.
What a mole visit looks like.
The tech walks the lawn and maps the tunnels. They test which runways are active. Traps go into the main runways. They check traps every day or two.
Moles, voles or gophers?
- Moles: raised ridges and round, volcano-shaped mounds. - Voles: narrow surface runways through the grass. - Gophers: crescent-shaped mounds with a plugged hole. - Chipmunks: small clean holes with no soil around them.
Watering and moles.
Moles follow moist soil, where worms rise near the surface. Water deeply and less often instead of a little every day. Fix leaky sprinklers that leave soggy corners.
Flower beds and borders.
Moles tunnel under beds looking for worms, not to eat plants. Plants wilt when their roots are left hanging in air pockets. Press tunnels down firmly and water to settle the soil.
Questions to ask before you sign.

Moles by the numbers.
Around Longmont, 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. Around Longmont, because moles are solitary, several fresh ridges usually mean more than one animal. Around Longmont, tunnels often run just under the surface, with deeper nesting chambers below, and a single mole can maintain an extensive system across a yard. Around Longmont, moles do not eat plants; they tunnel for earthworms, grubs, and soil insects, and the ridges they leave behind are what most people notice.

Questions people ask
Is per-mole or per-visit pricing better?
Per-mole pricing rewards results. Per-visit can cost less for a single mole.
Does lot size change the price?
Yes. Bigger lawns can have more moles and more tunnels to check.
What should a mole control quote include?
Around Longmont, the method, number of visits, what happens if more moles show up, and any lawn repair.
How much does mole control cost?

Are moles rodents?
They eat earthworms and grubs, not plant roots. They're insectivores, related to shrews. No.
Should I repair the lawn before or after trapping?
After. Fixing it first hides the tunnels you need to find.
Can I just flood the tunnels or fill them in?
It rarely works. Moles dig new tunnels or move a few feet away.
Will a dog get rid of moles in the yard?
Trapping in active runs remains the reliable method. Around Longmont, a dog may dig up a few tunnels and chase one mole off, but it will not clear a tunnel system, and the digging can do more lawn damage than the mole. Around Longmont, usually not, and there is no evidence that dogs are a reliable control.
Does chewing gum get rid of moles?
Around Longmont, time spent on folk remedies is better spent setting traps in the active runs. Moles feed on earthworms and grubs, not gum.
