Treatment options and typical costs
Activity Mapping and Tunnel Probing
$75–$200
A pro probes near fresh mounds to find the main tunnel. On a St. Louis lawn or orchard this is the step that tells trapping and baiting where to go.
- Time
- 45–90 minutes
- Best for
- Every job; separates fresh activity from old, abandoned mounds
Burrow Fumigation
$200–$600 per treatment
Because fumigation is invisible, follow-up matters even more than with trapping. A pro should come back to check for fresh mounds.
- Time
- 1–2 hours, with re-entry restrictions
- Best for
- Heavy activity on large lots, away from structures, where legal
Trapping in Active Tunnels
$150–$450 per visit series
Box and pincer traps go in the runway, not the mound. A provider will reset any trap that stays empty for two days, since the tunnel may be abandoned.
- Time
- 2–5 visits over 1–2 weeks
- Best for
- Small yards, gardens, homes with pets, and anyone avoiding poison
Labeled Burrow Baiting
$150–$400 per treatment
Tunnel-placed bait is far less risky to pets and wildlife than surface bait, but a St. Louis homeowner should still treat it seriously. Ask any St. Louis provider what they use and what the label says about dogs, cats, and children.
- Time
- 30–60 minutes per visit, plus follow-up
- Best for
- Larger properties and heavy infestations where trapping alone is too slow

Pocket gophers are stocky, with cheek pouches and long front claws. Each one lives alone.When they dig.
Frozen ground slows surface work in winter. Digging peaks in spring and fall, when soil is moist. Summer heat and dry soil push activity deeper.
Finding the main tunnel.
Louis out to Florissant and Kirkwood share the same pattern. Yards from St. That's where traps belong. Probe a foot or two back to find the main tunnel. The plugged hole is on the open side of the fan. Find a fresh, fan-shaped mound.
A year of digging in St. Louis.
- Spring: peak digging as soil warms and stays moist. - Winter: lows near 24°F in St. Louis. Surface work slows. - Fall: a second peak before winter. - Summer: highs near 89°F in St. Louis push activity deeper.
Gopher, mole or vole?
- Gopher: fan-shaped mounds, plugged hole to one side. - Chipmunk: neat holes, no dirt pile. - Vole: surface runways and chewed plant stems. - Mole: round mounds and raised ridges.
Protecting gardens and trees.
- Raised beds: line the bottom with hardware cloth. - Drip lines: check for chew marks each spring. - Bulbs: use small wire cages. - Trees: plant in wire root baskets.
What works, and what doesn’t.
- Works: traps in the main tunnel. - Rarely: plants said to repel gophers. - Rarely: sonic stakes, gum, castor oil or flooding. - Sometimes: labeled baits placed deep in tunnels.
How gopher traps are set.
- Find: probe near a fresh mound for the main tunnel. - 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.
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.
- Gum or laxatives: no evidence they work. - 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.
Signs the problem is over.
- No fresh mounds for two weeks. - New mounds later? Another one moved in. - Flattened mounds stay flat. - Plants stop wilting or disappearing.
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.
- Base: staple hardware cloth across the bottom. - Soil: fill after the wire is in place. - Edges: run the wire up the inside walls. - Wire: half-inch mesh, not chicken wire.
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.

How to size up the yard damage.
