Gopher Control in Hamilton, NJ

What to look for

Gophers get blamed for a lot of digging. Around Hamilton, 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 Hamilton.

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

When they dig.

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

Telling the diggers apart.

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

A year of digging in Hamilton.

• Winter: lows near 25°F in Hamilton. Surface work slows. - Spring: peak digging as soil warms and stays moist. - Summer: highs near 86°F in Hamilton push activity deeper. - Fall: a second peak before winter.

Gopher, mole or vole?

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

Protecting gardens and trees.

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

What works, and what doesn’t.

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

What helps with moles, voles and chipmunks.

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

Lawn care that discourages diggers.

Keep weedy edges and tall grass mowed. Pull mulch back from tree trunks. Healthy turf recovers from digging faster. Water deeply but less often.

Fixing the yard afterward.

Rake mounds flat and fill sunken tunnels. Water to settle the soil. Reseed or patch bare spots in spring or fall. Wait until the digging stops.

Irrigation lines and sprinklers.

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. Gophers chew drip lines and sprinkler tubing.

Natural help.

Barn owl boxes can help on bigger properties. Bait can harm pets and wildlife if misused. Traps avoid that risk. Owls, hawks, snakes and foxes all hunt gophers and voles.

Myths about yard diggers.

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

Signs the problem is over.

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

Underground wire baskets.

Leave a few inches of wire above the soil. Baskets last several years, long enough for roots to get established. Plant new trees, roses and bulbs in baskets of galvanized wire.

Raised beds that stay safe.

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

When a whole street has them.

Clearing your yard alone may only last a season. Talking with neighbors and treating at the same time works better. Diggers move in from vacant lots, fields and neighbors' yards.

Pets, kids and digging.

Choose traps over bait if a dog likes to dig. Fill old mounds so no one twists an ankle. Keep kids and pets away from traps and bait.

Gopher-proofing new landscaping.

Plant shrubs and trees in wire baskets. Raised beds with mesh bottoms protect vegetables. It costs more up front but saves replanting. Lay wire mesh under new sod before it goes down.

Questions to ask before you sign.

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

How to size up the yard damage.

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