Treatment options and typical costs
Activity Mapping and Tunnel Probing
$75–$200
This step makes or breaks the job. Traps in dead tunnels catch nothing. Careful probing is the least glamorous part and the most important.
- Time
- 45–90 minutes
- Best for
- Every job; separates fresh activity from old, abandoned mounds
Trapping in Active Tunnels
$150–$450 per visit series
Trapping is the most widely used method for gophers on Kennewick residential lots because it uses no toxicant and confirms the catch. The pro opens the runway, sets paired traps, and reseals it.
- 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
Properties in Kennewick that border pastures, canals, parks, or vacant lots tend to get recolonized within a season. A scheduled plan is often cheaper than repeated one-off calls.
- 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
A bait job should include a return visit. Open bait spots get closed. Bait placed and never rechecked is why many problems linger.
- 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 Kennewick.
Moles also live here; their mounds are round, not fan-shaped. They live alone, so a yard usually has one or two. Pocket gophers are stocky, with cheek pouches and long claws.
Gopher mounds are fan-shaped, with a plugged hole off to one side.When they dig.
Summer heat and dry soil push activity deeper. Mild winters keep them working most of the year. Digging peaks in spring and fall, when soil is moist.
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.
- Winter: mild in Kennewick, so digging continues. - Fall: a second peak before winter. - Summer: highs near 91°F in Kennewick push activity deeper. - Spring: peak digging as soil warms and stays moist.
Gopher, mole or vole?
- Chipmunk: neat holes, no dirt pile. - Vole: surface runways and chewed plant stems. - Mole: round mounds and raised ridges. - Gopher: fan-shaped mounds, plugged hole to one side.
Protecting gardens and trees.
- Drip lines: check for chew marks each spring. - Bulbs: use small wire cages. - Trees: plant in wire root baskets. - Raised beds: line the bottom with hardware cloth.
What works, and what doesn’t.
- Rarely: plants said to repel gophers. - Rarely: sonic stakes, gum, castor oil or flooding. - Sometimes: labeled baits placed deep in tunnels. - Works: traps in the main tunnel.
How gopher traps are set.
- Check: look again within a day. - Cover: block light with a board or sod. - Set: place a trap facing each way. - Open: dig down to expose both directions. - Find: probe near a fresh mound for the main tunnel.
Lawn care that discourages diggers.
Healthy turf recovers from digging faster. Pull mulch back from tree trunks. Keep weedy edges and tall grass mowed. Water deeply but less often.
Fixing the yard afterward.
Reseed or patch bare spots in spring or fall. Water to settle the soil. Rake mounds flat and fill sunken tunnels. Wait until the digging stops.
Irrigation lines and sprinklers.
Fix leaks fast, since damp soil draws more digging. Bury lines a little deeper where you can. Check for wet spots or weak spray each spring. Gophers chew drip lines and sprinkler tubing.
Natural help.
Traps avoid that risk. Bait can harm pets and wildlife if misused. Barn owl boxes can help on bigger properties. Owls, hawks, snakes and foxes all hunt gophers and voles.
Myths about yard diggers.
- Many mounds, many animals: often it’s one. - Repellent plants: little proof of results. - Sonic stakes: animals get used to them. - Car exhaust or flooding: unsafe and unreliable. - Gum or laxatives: no evidence they work.
Signs the problem is over.
- New mounds later? Another one moved in. - Flattened mounds stay flat. - Plants stop wilting or disappearing. - No fresh mounds for two weeks.
Underground wire baskets.
Baskets last several years, long enough for roots to get established. Leave a few inches of wire above the soil. Plant new trees, roses and bulbs in baskets of galvanized wire.
Raised beds that stay safe.
- Soil: fill after the wire is in place. - Edges: run the wire up the inside walls. - Wire: half-inch mesh, not chicken wire. - Base: staple hardware cloth across the bottom.
When a whole street has them.
Talking with neighbors and treating at the same time works better. Clearing your yard alone may only last a season. Diggers move in from vacant lots, fields and neighbors' yards.
Pets, kids and digging.
Fill old mounds so no one twists an ankle. Choose traps over bait if a dog likes to dig. Keep kids and pets away from traps and bait.
Gopher-proofing new landscaping.
It costs more up front but saves replanting. Raised beds with mesh bottoms protect vegetables. Plant shrubs and trees in wire baskets. Lay wire mesh under new sod before it goes down.
Questions to ask before you sign.
- Is it safe around pets? - What if another one moves in? - How often will you check? - Which method will you use? - Is it a gopher, mole or vole?
Ways to keep the cost down.
- Protect beds and trees with wire. - Trap early, when there’s just one. - Confirm what’s digging before paying for treatment.
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
- Season, with spring and fall needing more follow-up.
- Proximity of activity to buildings and hardscape.
- Access difficulty, slopes, and dense plantings.
- How many recheck visits the plan includes.
- Trapping versus baiting versus fumigation.
- Whether wire baskets or buried mesh are requested.
- State restrictions on which baits can be used.
- One-time service versus a monthly monitoring plan.
