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 Washington are busiest in spring and fall. They tunnel near the surface after rain. One mole can dig a lot of tunnel.

Treatment options and typical costs
Runway Identification and Activity Survey
$75–$200
In Washington, a survey also looks at what is feeding the moles: soil moisture, worm density, and grub activity. Ridges along foundations, walks, and bed edges usually mark main runways. Mapping them first avoids traps in dead tunnels.
- Time
- 45–90 minutes
- Best for
- Every job; trapping fails without it
Active-Runway Trapping
$150–$400 per visit; multi-visit plans $300–$900
Trapping in Washington is a process rather than a one-time visit. Sets are checked, moved, and repeated until activity stops. Providers around Washington usually price this as a plan with a set number of visits.
- Time
- 30–60 minutes per visit, over several visits
- Best for
- Most yards; the most reliable method
Follow-Up Monitoring
$50–$150 per visit; often included in plans
Monitoring visits in Washington are short but important. The provider rechecks flattened tunnels, looks for new mounds, and resets traps on any Washington runway that reopened. Many Washington 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
In larger Washington properties where trapping every runway is impractical, mole-labeled baits can reach tunnels traps cannot cover. They go into active tunnels and the openings are closed. Pets and children should be kept off treated Washington runways per the label.
- Time
- 30–45 minutes
- Best for
- Large or hard-to-trap areas; used exactly as labeled

Which moles live around Washington.
The eastern mole is the one digging up lawns around Washington. It's gray, about six inches long, with big spade-like front feet. Moles are insectivores, not rodents. They eat earthworms and grubs, not roots.
Raised ridges are feeding tunnels just under the turf. Many are used once and abandoned.When they tunnel.
Mild winters keep them near the surface. Summer heat and drought also push them down.
Finding an active tunnel.
Look for fresh ridges and mounds after rain. 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. Around Washington, edges along walks and beds are the best bets.
A year of moles in Washington.
- Winter: mild in Washington. Moles stay active. - Fall: a second burst near the surface. - Summer: highs near 89°F in Washington push moles deeper. - Spring: peak tunneling. Best time to trap.
Mole, gopher or vole?
- Damage: moles don’t eat plants; gophers and voles do. - Vole: surface runways and small holes in the grass. - Gopher: crescent-shaped mounds with a plugged hole. - Mole: raised ridges and round, volcano-like mounds.
What works, and what doesn’t.
- Rarely alone: grub control, since they mostly eat earthworms. - Rarely: castor oil, sonic stakes, gum or flooding. - Sometimes: labeled baits, used deep in tunnels. - Works: traps set in active runways.
Protecting garden beds.
It's work up front, but it lasts for years. Raised beds can get a mesh floor before you fill them. Bend the bottom edge outward. Bury quarter-inch hardware cloth around beds, about two feet deep.
Lawn care that helps.
Grub control alone rarely moves moles on. Healthy turf recovers from tunnels faster. Constantly wet lawns draw earthworms, and moles follow. Water deeply but less often.
Signs the problem is over.
- New ridges? Another mole may have moved in. - Traps stay untouched for several checks. - Stepped-down runways stay flat. - No new mounds for two weeks.
Choosing a trap.
- Rules: check what your state allows first. - Placement: main runways beat fresh feeding ridges. - Tunnel traps: sit inside a dug-out runway. - Harpoon traps: set on top of a pressed-down ridge. - Scissor traps: set straddling an active runway.
Mole myths.
- Flooding tunnels: they just dig new ones. - Many mounds, many moles: usually it’s one or two. - Moles eat bulbs: no, voles using their tunnels do. - Castor oil: may move them briefly, not away. - Chewing gum in tunnels: no evidence it works.
Moles aren’t all bad.
In a front lawn or garden, most people want them gone. A mole in a field may be fine to leave. They eat grubs and other insect larvae. Moles loosen and aerate soil.
Fixing the lawn afterward.
Overseed bare spots in spring or fall. Water to settle the soil. Rake mounds flat and step ridges down. Wait until the mole is caught.
Moles, kids and pets.
Digging dogs can wreck a lawn faster than moles. Baits must go deep in tunnels, exactly as the label says. Keep kids and pets away from traps. Moles don't bite unless handled.
What a mole visit looks like.
They check traps every day or two. Traps go into the main runways. They test which runways are active. The tech walks the lawn and maps the tunnels.
Moles, voles or gophers?
- Chipmunks: small clean holes with no soil around them. - Gophers: crescent-shaped mounds with a plugged hole. - Voles: narrow surface runways through the grass. - Moles: raised ridges and round, volcano-shaped mounds.
Watering and moles.
Fix leaky sprinklers that leave soggy corners. Water deeply and less often instead of a little every day. Moles follow moist soil, where worms rise near the surface.
Flower beds and borders.
Press tunnels down firmly and water to settle the soil. Plants wilt when their roots are left hanging in air pockets. Moles tunnel under beds looking for worms, not to eat plants.
Questions to ask before you sign.
- Is lawn repair included? - What if another mole moves in? - How often will you check traps? - Which method will you use? - Is it a mole, gopher or vole?
Ways to keep the cost down.
- Repair the lawn yourself afterward. - Ask about per-mole pricing. - Skip repellents that rarely work. - Call early, before tunnels spread.
Moles by the numbers.
In Washington, moles do not eat plants; they tunnel for earthworms, grubs, and soil insects, and the ridges they leave behind are what most people notice. In Washington, tunnels often run just under the surface, with deeper nesting chambers below, and a single mole can maintain an extensive system across a yard. In Washington, because moles are solitary, several fresh ridges usually mean more than one animal. In Washington, 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.
What affects the price
- Travel distance to rural properties.
- Lot size and number of active runways.
- Provider type: wildlife operator versus lawn company.
- Season, since spring and fall book fastest.
- Irrigation and drainage corrections.
- Access around fences, slopes, and dense plantings.
- Single visit versus a multi-visit trapping plan.
- Mole-labeled bait applications added to trapping.

What bothers you most about moles?
When to call for help
Call if new mounds keep appearing for more than a week. if you can't find an active runway. A pro can usually catch the mole within a few visits.
What you can do yourself
Skip sonic stakes, gum and flooding. Set the trap exactly as the instructions say. Find an active runway first. Trapping yourself can work.
Moles in Washington
In Washington, parks, ballfields and watered yards see the most tunneling. Winters around Washington are mild enough that moles can stay active near the surface. With about 40 inches of rain a year, Washington keeps soil soft and full of earthworms, which moles love.

Questions people ask
Do homeowners prefer DIY mole trapping or hiring a pro?
In Washington, many homeowners try trapping themselves first because it is the cheapest option and traps are sold everywhere. In Washington, 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.
How much does mole control cost?
Most jobs around Washington cost about $150–$400 per visit. Multi-visit plans run more.
Why do multi-visit plans cost more?
Trapping takes daily or near-daily checks until the mole is caught.
Does the season affect pricing?
Spring and fall are busiest. Booking early can help.
How many moles are in my yard?
Usually just one to three.
What is the difference between mole and gopher damage?
Moles push up round, volcano-like mounds and raised ridges. Gophers leave crescent-shaped mounds with a plugged hole to one side.
Are mole baits safe around pets and children?
Use them only as the label directs, deep in tunnels. Traps are often the safer choice.
Will a dog get rid of moles in the yard?
Trapping in active runs remains the reliable method. In Washington, 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. In Washington, usually not, and there is no evidence that dogs are a reliable control.
When are moles most active in Washington?
Spring and fall, especially after rain. Mild winters keep some activity going year-round.
Are moles common in Washington?
Yes.
