Homeowners and gardeners in Kennewick with mounds or tunnels in 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 Kennewick. 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 Kennewick 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
Exclusion and Follow-Up Monitoring
$200–$1,500 depending on scope
After trapping or baiting, a provider should flatten every mound and return in a week or two to check for new ones. No fresh soil over that period is the definition of done.
- Time
- Half a day for barriers; monitoring visits 20–40 minutes
- Best for
- Gardens, raised beds, young trees, and properties near open fields
Burrow Fumigation
$200–$600 per treatment
Where local rules or property layout rule out fumigation in Kennewick, trapping and baiting cover the same ground more slowly. Providers should say plainly when fumigation is not an option.
- Time
- 1–2 hours, with re-entry restrictions
- Best for
- Heavy activity on large lots, away from structures, where legal

Gophers eat roots from below. Plants that wilt and lift out easily are a classic sign.Which gophers live around Kennewick.
Pocket gophers are stocky, with cheek pouches and long claws. They live alone, so a yard usually has one or two. Moles also live here; their mounds are round, not fan-shaped.
When they dig.
Digging peaks in spring and fall, when soil is moist. Mild winters keep them working most of the year. Summer heat and dry soil push activity deeper.
Pocket gophers are stocky, with cheek pouches and long front claws. Each one lives alone.Finding the main tunnel.
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. Yards from Kennewick out to Richland share the same pattern.
A year of digging in Kennewick.
- Spring: peak digging as soil warms and stays moist. - Summer: highs near 91°F in Kennewick push activity deeper. - Fall: a second peak before winter. - Winter: mild in Kennewick, so digging continues.
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.
Water deeply but less often. Keep weedy edges and tall grass mowed. Pull mulch back from tree trunks. Healthy turf recovers from digging faster.
Fixing the yard afterward.
Wait until the digging stops. Rake mounds flat and fill sunken tunnels. Water to settle the soil. Reseed or patch bare spots in spring or fall.
Irrigation lines and sprinklers.
Gophers chew drip lines and sprinkler tubing. Check for wet spots or weak spray each spring. Bury lines a little deeper where you can. Fix leaks fast, since damp soil draws more digging.
Natural help.
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. Traps avoid that risk.
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.
Lay wire mesh under new sod before it goes down. Plant shrubs and trees in wire baskets. Raised beds with mesh bottoms protect vegetables. It costs more up front but saves replanting.
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?
How to size up the yard damage.
In Kennewick, 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. In Kennewick, tunnel systems typically run 6 to 12 inches below the surface, with deeper nesting and food-storage chambers. In Kennewick, because each gopher is solitary, a yard with several fresh mounds usually means several animals, each with its own network. In Kennewick, count the active mounds during your walk-through — that number, not a national average, is what should drive a treatment plan.
What affects the price
- State restrictions on which baits can be used.
- Trapping versus baiting versus fumigation.
- Travel distance from the provider to the property.
- Whether wire baskets or buried mesh are requested.
- Documentation requirements for HOAs or property managers.
- Soil type, since dry or sandy ground limits fumigants.

Gophers in Kennewick

In Kennewick's neighborhoods, lawns and vegetable gardens next to open lots are hot spots.

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

Questions people ask
Is gopher fumigation legal where I live?
Rules vary by state and product. Ask a licensed company what's allowed in Washington.
