Treatment options and typical costs

Prices are typical published ranges. Ask what’s included before you compare quotes.

Which gophers live around Olympia.

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.

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 Olympia out to Tacoma and Federal Way 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 Olympia.

• Fall: a second peak before winter. - Summer: highs near 78°F in Olympia push activity deeper. - Spring: peak digging as soil warms and stays moist. - Winter: mild in Olympia, 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?

How to size up the yard damage.

For Olympia homes, because each gopher is solitary, a yard with several fresh mounds usually means several animals, each with its own network. For Olympia homes, count the active mounds during your walk-through — that number, not a national average, is what should drive a treatment plan. For Olympia 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 Olympia homes, tunnel systems typically run 6 to 12 inches below the surface, with deeper nesting and food-storage chambers.

Gopher mounds vs. other lawn damage in Olympia.

Around Olympia, WA, 51 inches of rain a year softens the soil and makes new mounds more visible after a wet spell. For Olympia homes, reading the shape of the mound is the first step in choosing the right control method. For Olympia homes, gopher activity shows up as fan-shaped mounds of fresh soil with a plugged entrance off to one side. For Olympia homes, the mounds are the giveaway — moles leave raised ridges without a clear entrance hole, and voles leave shallow surface runways through the grass.

What a gopher control job should cost in Olympia.

For Olympia homes, a small yard with one or two active tunnels is a small job; a large lot with tunneling across a wide area costs more because it takes more traps and more return visits. For Olympia homes, ask for a written quote that spells out the number of visits, the method, and what the follow-up covers, rather than a single flat number. For Olympia homes, gopher control is priced by how many active tunnels there are and how much ground the animal is using, not by how many animals you can count.

Why gopher problems come back after removal.

For Olympia homes, that is why removal alone rarely holds: if the food and the tunnel access are still there, a new gopher will simply re-colonize the same tunnels. For Olympia homes, the long-term fix pairs removal with habitat changes, like limiting the grubs and earthworms or irrigated plantings gophers feed on and keeping nearby overgrown areas trimmed, so your yard stops being the easiest target on the block. For Olympia homes, gophers are solitary, but the space they leave is quickly filled by the next animal that moves in from neighboring yards or open ground.

Simple ways to keep gophers away

• Line raised beds with wire mesh.
• Plant trees in wire root baskets.
• Check for fresh mounds weekly.
• Trap new gophers early.
• Keep weedy field edges mowed.
• Skip sonic stakes and repellents.
