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 Sunnyvale 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
Burrow Fumigation
$200–$600 per treatment
Legal setbacks from homes, sheds, and neighboring buildings are not optional. Any Sunnyvale provider offering fumigation should explain those setbacks before scheduling.
- Time
- 1–2 hours, with re-entry restrictions
- Best for
- Heavy activity on large lots, away from structures, where legal
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 Sunnyvale.
They live alone, so a yard usually has one or two. Pocket gophers are stocky, with cheek pouches and long claws. Moles also live here; their mounds are round, not fan-shaped.
Gopher mounds are fan-shaped, with a plugged hole off to one side.When they dig.
Mild winters keep them working most of the year. Digging peaks in spring and fall, when soil is moist. Summer heat and dry soil push activity deeper.
Finding the main tunnel.
Probe a foot or two back to find the main tunnel. That's where traps belong. Yards from Sunnyvale out to San Jose and Fremont share the same pattern. Find a fresh, fan-shaped mound. The plugged hole is on the open side of the fan.
A year of digging in Sunnyvale.
- Fall: a second peak before winter. - Summer: highs near 80°F in Sunnyvale push activity deeper. - Spring: peak digging as soil warms and stays moist. - Winter: mild in Sunnyvale, so digging continues.
Gopher, mole or vole?
- Vole: surface runways and chewed plant stems. - Mole: round mounds and raised ridges. - Gopher: fan-shaped mounds, plugged hole to one side. - Chipmunk: neat holes, no dirt pile.
Protecting gardens and trees.
- Bulbs: use small wire cages. - Trees: plant in wire root baskets. - Raised beds: line the bottom with hardware cloth. - Drip lines: check for chew marks each spring.
What works, and what doesn’t.
- Rarely: sonic stakes, gum, castor oil or flooding. - Sometimes: labeled baits placed deep in tunnels. - Works: traps in the main tunnel. - Rarely: plants said to repel gophers.
How gopher traps are set.
- 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. - Check: look again within a day.
Lawn care that discourages diggers.
Keep weedy edges and tall grass mowed. Water deeply but less often. Healthy turf recovers from digging faster. Pull mulch back from tree trunks.
Fixing the yard afterward.
Rake mounds flat and fill sunken tunnels. Wait until the digging stops. Reseed or patch bare spots in spring or fall. Water to settle the soil.
Irrigation lines and sprinklers.
Check for wet spots or weak spray each spring. Gophers chew drip lines and sprinkler tubing. Fix leaks fast, since damp soil draws more digging. Bury lines a little deeper where you can.
Natural help.
Barn owl boxes can help on bigger properties. Owls, hawks, snakes and foxes all hunt gophers and voles. Traps avoid that risk. Bait can harm pets and wildlife if misused.
Myths about yard diggers.
- 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. - Many mounds, many animals: often it’s one.
Signs the problem is over.
- Flattened mounds stay flat. - Plants stop wilting or disappearing. - No fresh mounds for two weeks. - New mounds later? Another one moved in.
Underground wire baskets.
Leave a few inches of wire above the soil. Plant new trees, roses and bulbs in baskets of galvanized wire. Baskets last several years, long enough for roots to get established.
Raised beds that stay safe.
- Edges: run the wire up the inside walls. - Wire: half-inch mesh, not chicken wire. - Base: staple hardware cloth across the bottom. - Soil: fill after the wire is in place.
When a whole street has them.
Clearing your yard alone may only last a season. Diggers move in from vacant lots, fields and neighbors' yards. Talking with neighbors and treating at the same time works better.
Pets, kids and digging.
Choose traps over bait if a dog likes to dig. Keep kids and pets away from traps and bait. Fill old mounds so no one twists an ankle.
Gopher-proofing new landscaping.
Plant shrubs and trees in wire baskets. Lay wire mesh under new sod before it goes down. It costs more up front but saves replanting. Raised beds with mesh bottoms protect vegetables.
Questions to ask before you sign.
- What if another one moves in? - How often will you check? - Which method will you use? - Is it a gopher, mole or vole? - Is it safe around pets?
Ways to keep the cost down.
- Trap early, when there’s just one. - Confirm what’s digging before paying for treatment. - Protect beds and trees with wire.
How to size up the yard damage.
For Sunnyvale homes, because each gopher is solitary, a yard with several fresh mounds usually means several animals, each with its own network. For Sunnyvale homes, count the active mounds during your walk-through — that number, not a national average, is what should drive a treatment plan. For Sunnyvale homes, 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. For Sunnyvale homes, tunnel systems typically run 6 to 12 inches below the surface, with deeper nesting and food-storage chambers.
What affects the price
- Need for soil fill or hardscape repair afterward.
- State restrictions on which baits can be used.
- Trapping versus baiting versus fumigation.
- Whether wire baskets or buried mesh are requested.
- Access difficulty, slopes, and dense plantings.
- Documentation requirements for HOAs or property managers.
- Proximity of activity to buildings and hardscape.
- Lot size and total ground the provider must cover.

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.
