Which moles live around San Mateo.

Moles are insectivores, not rodents. They eat earthworms and grubs, not roots. Around San Mateo, Townsend's, coast or broad-footed moles do the digging. They push up more mounds than eastern moles.

When they tunnel.

Mild winters keep them near the surface. Summer heat and drought also push them down.

Finding an active tunnel.

If it's raised again, it's active. Main runways often follow edges: walks, fences and beds. Lawns from San Mateo out to San Francisco and Oakland show the same pattern. Look for fresh ridges and mounds after rain. Step down a short stretch of tunnel and mark it. Check it in a day or two.

A year of moles in San Mateo.

• Fall: a second burst near the surface. - Winter: mild in San Mateo. Moles stay active. - Spring: peak tunneling. Best time to trap. - Summer: highs near 78°F in San Mateo push moles deeper.

Mole, gopher or vole?

• Vole: surface runways and small holes in the grass. - Damage: moles don’t eat plants; gophers and voles do. - Mole: raised ridges and round, volcano-like mounds. - Gopher: crescent-shaped mounds with a plugged hole.

What works, and what doesn’t.

• Rarely: castor oil, sonic stakes, gum or flooding. - Rarely alone: grub control, since they mostly eat earthworms. - Works: traps set in active runways. - Sometimes: labeled baits, used deep in tunnels.

Protecting garden beds.

Bury quarter-inch hardware cloth around beds, about two feet deep. Bend the bottom edge outward. Raised beds can get a mesh floor before you fill them. It's work up front, but it lasts for years.

Lawn care that helps.

Water deeply but less often. Constantly wet lawns draw earthworms, and moles follow. Healthy turf recovers from tunnels faster. Grub control alone rarely moves moles on.

Signs the problem is over.

• Traps stay untouched for several checks. - New ridges? Another mole may have moved in. - No new mounds for two weeks. - Stepped-down runways stay flat.

Choosing a trap.

• Tunnel traps: sit inside a dug-out runway. - Placement: main runways beat fresh feeding ridges. - Rules: check what your state allows first. - Scissor traps: set straddling an active runway. - Harpoon traps: set on top of a pressed-down ridge.

Mole myths.

• Moles eat bulbs: no, voles using their tunnels do. - Many mounds, many moles: usually it’s one or two. - Flooding tunnels: they just dig new ones. - Chewing gum in tunnels: no evidence it works. - Castor oil: may move them briefly, not away.

Moles aren’t all bad.

Moles loosen and aerate soil. They eat grubs and other insect larvae. A mole in a field may be fine to leave. In a front lawn or garden, most people want them gone.

Fixing the lawn afterward.

Wait until the mole is caught. Rake mounds flat and step ridges down. Water to settle the soil. Overseed bare spots in spring or fall.

Moles, kids and pets.

Moles don't bite unless handled. Keep kids and pets away from traps. Baits must go deep in tunnels, exactly as the label says. Digging dogs can wreck a lawn faster than moles.

What a mole visit looks like.

The tech walks the lawn and maps the tunnels. They test which runways are active. Traps go into the main runways. They check traps every day or two.

Moles, voles or gophers?

• Gophers: crescent-shaped mounds with a plugged hole. - Chipmunks: small clean holes with no soil around them. - Moles: raised ridges and round, volcano-shaped mounds. - Voles: narrow surface runways through the grass.

Watering and moles.

Moles follow moist soil, where worms rise near the surface. Water deeply and less often instead of a little every day. Fix leaky sprinklers that leave soggy corners.

Flower beds and borders.

Moles tunnel under beds looking for worms, not to eat plants. Plants wilt when their roots are left hanging in air pockets. Press tunnels down firmly and water to settle the soil.

Questions to ask before you sign.

• How often will you check traps? - What if another mole moves in? - Is lawn repair included? - Is it a mole, gopher or vole? - Which method will you use?

Ways to keep the cost down.

• Ask about per-mole pricing. - Repair the lawn yourself afterward. - Call early, before tunnels spread. - Skip repellents that rarely work.

Moles by the numbers.

For San Mateo homes, because moles are solitary, several fresh ridges usually mean more than one animal. For San Mateo homes, before you hire, walk the yard and flatten a few ridges with your foot, then check back the next day — the ones that are raised again are the active runs a plan should target. For San Mateo homes, moles do not eat plants; they tunnel for earthworms, grubs, and soil insects, and the ridges they leave behind are what most people notice. For San Mateo homes, tunnels often run just under the surface, with deeper nesting chambers below, and a single mole can maintain an extensive system across a yard.

Simple ways to keep moles away

• Edge beds with buried hardware cloth.
• Check for fresh mounds after rain.
• Act early in spring.
• Fix tunnels only after trapping.
• Skip sonic stakes and castor oil.
