Gopher Control Cost in Washington, DC

What to look for

Gophers get blamed for a lot of digging. Around Washington, it's almost always something else. Moles push up round mounds and ridges. Voles chew runways through the grass and eat plants.

• 1Round, volcano-shaped mounds (moles).
• 2Raised ridges in the lawn (moles).
• 3Surface runways in the grass (voles).
• 4Small holes near walls and patios (chipmunks).
• 5Plants chewed at the base (voles).

What's really digging around Washington.

Chipmunks dig neat holes near patios and walls. Getting the ID right in Washington saves money and time. Eastern moles cause most lawn tunnels here. Meadow and pine voles eat plants and leave narrow runways.

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.

Telling the diggers apart.

Look at the mound shape first. Round and volcano-like means a mole. Narrow runways in the grass mean voles. Neat holes with no dirt pile often mean chipmunks. Around Washington, check gardens and lawn edges first.

A year of digging in Washington.

• Fall: a second peak before winter. - Winter: mild in Washington, so digging continues. - Spring: peak digging as soil warms and stays moist. - Summer: highs near 89°F in Washington push activity deeper.

Gopher, mole or vole?

• Vole: surface runways and chewed plant stems. - Chipmunk: neat holes, no dirt pile. - Gopher: fan-shaped mounds, plugged hole to one side. - Mole: round mounds and raised ridges.

Protecting gardens and trees.

• Bulbs: use small wire cages. - Drip lines: check for chew marks each spring. - Raised beds: line the bottom with hardware cloth. - Trees: plant in wire root baskets.

What works, and what doesn’t.

• Rarely: sonic stakes, gum, castor oil or flooding. - Rarely: plants said to repel gophers. - Works: traps in the main tunnel. - Sometimes: labeled baits placed deep in tunnels.

What helps with moles, voles and chipmunks.

• Chipmunks: seal gaps under patios and steps. - All three: wire mesh under beds and around bulbs. - Skip: poisons near pets and wildlife. - Moles: traps set in active runways. - Voles: mow tall grass and clear mulch from plant stems.

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.

• Sonic stakes: animals get used to them. - Repellent plants: little proof of results. - Many mounds, many animals: often it’s one. - Gum or laxatives: no evidence they work. - Car exhaust or flooding: unsafe and unreliable.

Signs the problem is over.

• Flattened mounds stay flat. - New mounds later? Another one moved in. - No fresh mounds for two weeks. - Plants stop wilting or disappearing.

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.

• Edges: run the wire up the inside walls. - Soil: fill after the wire is in place. - Base: staple hardware cloth across the bottom. - Wire: half-inch mesh, not chicken wire.

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.

• How often will you check? - What if another one moves in? - Is it safe around pets? - Is it a gopher, mole or vole? - Which method will you use?

Ways to keep the cost down.

• Protect beds and trees with wire. - Confirm what’s digging before paying for treatment. - Trap early, when there’s just one.

How to size up the yard damage.

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

Simple ways to keep gophers away

• Identify the digger before treating.
• Line raised beds with wire mesh.
• Protect bulbs with wire baskets.
• Keep grass mowed to discourage voles.
• Clear brush where chipmunks hide.
