• 3Surface runways in the grass (voles).
• 4Small holes near walls and patios (chipmunks).

What's really digging around Waltham.

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

When they dig.

Summer heat and dry soil push activity deeper. Frozen ground slows surface work in winter. Digging peaks in spring and fall, when soil is moist.

Telling the diggers apart.

Yards from Waltham out to Newton and Brookline share the same pattern. Neat holes with no dirt pile often mean chipmunks. Narrow runways in the grass mean voles. Round and volcano-like means a mole. Look at the mound shape first.

A year of digging in Waltham.

• Winter: lows near 19°F in Waltham. Surface work slows. - Fall: a second peak before winter. - Summer: highs near 83°F in Waltham 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.

What helps with moles, voles and chipmunks.

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

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?

How to size up the yard damage.

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

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.
