The short version
Moles are usually one to three animals. Find an active tunnel, then trap it. Repellents and sonic stakes rarely work.
- Usually one to three moles.
- Find an active runway first.
- Traps work best; repellents rarely do.
- Moles eat earthworms, not plants.
- Fix the lawn after trapping.
Homeowners in Kent with tunnels, ridges or mounds in the lawn.
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. Moles around Kent are busiest in spring and fall. They tunnel near the surface after rain. One mole can dig a lot of tunnel.
- 1Raised ridges across the lawn.
- 2Round, volcano-shaped dirt mounds.
- 3Spongy patches underfoot.
- 4Tunnels along walkways and beds.
- 5Fresh mounds after rain.
- 6Dead turf strips over tunnels.
Why it’s worth acting soon
- Tunnels spread across the lawn.
- Mounds make mowing harder.
- Ridges become trip hazards.
- New moles move into empty tunnels.
Treatment options and typical costs
Runway Identification and Activity Survey
$75–$200
Expect questions about when and where mounds appeared. Then they flatten runways to confirm which lines are live. The result is a short list of Kent trap locations, not guesswork.
- Time
- 45–90 minutes
- Best for
- Every job; trapping fails without it
Lawn, Moisture, and Bed Exclusion Work
$150–$450 depending on scope
Grub control is often sold as mole control, with real limits. Moles eat mostly earthworms, so a Kent lawn with no grubs can still host them. Across Kent, a provider should be honest that habitat work supports trapping rather than replacing it.
- Time
- 1–4 hours
- Best for
- Repeat problems; protecting beds and small areas
Mole-Labeled Baits
$100–$300 per application
Baits are not a shortcut; they only work in live tunnels. That is why Kent providers run the flattening test before any bait goes down. Bait in a dead tunnel in Kent is wasted product.
- Time
- 30–45 minutes
- Best for
- Large or hard-to-trap areas; used exactly as labeled
Active-Runway Trapping
$150–$400 per visit; multi-visit plans $300–$900
Trapping is the method most extension services recommend for moles. Traps go over confirmed active runways. They're rechecked within a day or two. Traps that go untouched get moved to fresh Kent runways.
- Time
- 30–60 minutes per visit, over several visits
- Best for
- Most yards; the most reliable method

Main runways often follow edges like beds, walks and fences. That's where traps work best.Which moles live around Kent.
They push up more mounds than eastern moles. Moles are insectivores, not rodents. They eat earthworms and grubs, not roots. Around Kent, Townsend's, coast or broad-footed moles do the digging.
When they tunnel.
Mild winters keep them near the surface. Summer heat and drought also push them down.
Raised ridges are feeding tunnels just under the turf. Many are used once and abandoned.Finding an active tunnel.
Step down a short stretch of tunnel and mark it. Check it in a day or two. If it's raised again, it's active. Main runways often follow edges: walks, fences and beds. Lawns from Kent out to Auburn and Federal Way show the same pattern. Look for fresh ridges and mounds after rain.
A year of moles in Kent.
- Winter: mild in Kent. Moles stay active. - Spring: peak tunneling. Best time to trap. - Summer: highs near 77°F in Kent push moles deeper. - Fall: a second burst near the surface.
Mole, gopher or vole?
- Damage: moles don’t eat plants; gophers and voles do. - 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.
What works, and what doesn’t.
- Rarely alone: grub control, since they mostly eat earthworms. - Works: traps set in active runways. - Sometimes: labeled baits, used deep in tunnels. - Rarely: castor oil, sonic stakes, gum or flooding.
Protecting garden beds.
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. Bury quarter-inch hardware cloth around beds, about two feet deep.
Lawn care that helps.
Constantly wet lawns draw earthworms, and moles follow. Healthy turf recovers from tunnels faster. Grub control alone rarely moves moles on. Water deeply but less often.
Signs the problem is over.
- New ridges? Another mole may have moved in. - No new mounds for two weeks. - Stepped-down runways stay flat. - Traps stay untouched for several checks.
Choosing a trap.
- Rules: check what your state allows first. - 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.
Mole myths.
- Flooding tunnels: they just dig new ones. - 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.
Moles aren’t all bad.
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. Moles loosen and aerate soil.
Fixing the lawn afterward.
Rake mounds flat and step ridges down. Water to settle the soil. Overseed bare spots in spring or fall. Wait until the mole is caught.
Moles, kids and pets.
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. Moles don't bite unless handled.
What a mole visit looks like.
They test which runways are active. Traps go into the main runways. They check traps every day or two. The tech walks the lawn and maps the tunnels.
Moles, voles or gophers?
- Chipmunks: small clean holes with no soil around them. - Moles: raised ridges and round, volcano-shaped mounds. - Voles: narrow surface runways through the grass. - Gophers: crescent-shaped mounds with a plugged hole.
Watering and moles.
Water deeply and less often instead of a little every day. Fix leaky sprinklers that leave soggy corners. Moles follow moist soil, where worms rise near the surface.
Flower beds and borders.
Plants wilt when their roots are left hanging in air pockets. Press tunnels down firmly and water to settle the soil. Moles tunnel under beds looking for worms, not to eat plants.
Questions to ask before you sign.
- Is lawn repair included? - Is it a mole, gopher or vole? - Which method will you use? - How often will you check traps? - What if another mole moves in?
Moles by the numbers.
Across Kent, tunnels often run just under the surface, with deeper nesting chambers below, and a single mole can maintain an extensive system across a yard. Across Kent, because moles are solitary, several fresh ridges usually mean more than one animal. Across Kent, 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. Across Kent, moles do not eat plants; they tunnel for earthworms, grubs, and soil insects, and the ridges they leave behind are what most people notice.
What affects the price
- Number of moles present on the property.
- Season, since spring and fall book fastest.
- Buried barriers for raised beds or gardens.
- Lot size and number of active runways.
- Single visit versus a multi-visit trapping plan.
- Irrigation and drainage corrections.

What bothers you most about moles?
When to call for help
if you can't find an active runway. A pro can usually catch the mole within a few visits. Call if new mounds keep appearing for more than a week.
What you can do yourself
Set the trap exactly as the instructions say. Skip sonic stakes, gum and flooding. Trapping yourself can work.
Moles in Kent
Kent gets about 39 inches of rain a year, so moles favor watered lawns and shady beds. Winters around Kent are mild enough that moles can stay active near the surface. Across Kent, parks, ballfields and watered yards see the most tunneling. Across Kent, the marine west coast climate means moles activity tends to follow spring and fall; active year-round in mild soil, so scheduling the visit before the busy stretch usually means a faster response and a cleaner quote.
Local research
Moles in Kent, WA: what the public record shows
Before you compare quotes, it helps to know which moles actually live in Washington, when they are busiest around Kent, and what the state figures look like. Everything below links to the agency or university page it came from.
Mole species recorded in Washington

Moles are related to shrews, not mice
One mole can hold a territory over an acre
Questions people ask
Is the mole still in my yard?
Step down a short section of tunnel. If it's raised again in a day or two, it's active.
Are moles rodents?
No. They're insectivores, related to shrews. They eat earthworms and grubs, not plant roots.
Can I just flood the tunnels or fill them in?
It rarely works. Moles dig new tunnels or move a few feet away.
Why do repellents and sonic stakes not work on moles?
Moles get used to them or tunnel around them. Studies show little lasting effect.
Should I repair the lawn before or after trapping?
After. Fixing it first hides the tunnels you need to find.
Do homeowners prefer DIY mole trapping or hiring a pro?
Across Kent, many homeowners try trapping themselves first because it is the cheapest option and traps are sold everywhere. Across Kent, a professional usually makes sense when tunnels keep reappearing after several weeks of trapping, when the damage covers a large area, or when you would rather not handle traps and dispose of animals yourself.
Is the GopherHawk trap popular for moles?
Across Kent, the GopherHawk is a commonly discussed scissor-jaw trap, but popularity is not the same as effectiveness. Across Kent, like any trap, it works only when set in an active run and checked often. Across Kent, choose a trap you can set correctly and check daily, and focus on finding the active tunnel first.
When are moles most active in Kent?
Spring and fall, especially after rain. Mild winters keep some activity going year-round.
Are moles common in Kent?
Yes.
