Homeowners in Downers Grove with tunnels, ridges or mounds in the lawn.
What to look for
Moles don't eat plants. They hunt earthworms and grubs. Their tunnels lift turf, dry out roots and trip people up. Moles around Downers Grove are busiest in spring and fall. They tunnel near the surface after rain. One mole can dig a lot of tunnel.
- 1Raised ridges across the lawn.
- 2Round, volcano-shaped dirt mounds.
- 3Spongy patches underfoot.
- 4Tunnels along walkways and beds.
- 5Fresh mounds after rain.
- 6Dead turf strips over tunnels.
Why it’s worth acting soon
- Tunnels spread across the lawn.
- Mounds make mowing harder.
- Ridges become trip hazards.
- New moles move into empty tunnels.
Treatment options and typical costs
Runway Identification and Activity Survey
$75–$200
Expect questions about when and where mounds appeared. Then they flatten runways to confirm which lines are live. The result is a short list of Downers Grove trap locations, not guesswork.
- Time
- 45–90 minutes
- Best for
- Every job; trapping fails without it
Lawn, Moisture, and Bed Exclusion Work
$150–$450 depending on scope
Grub control is often sold as mole control, with real limits. Moles eat mostly earthworms, so a Downers Grove lawn with no grubs can still host them. For Downers Grove homes, a provider should be honest that habitat work supports trapping rather than replacing it.
- Time
- 1–4 hours
- Best for
- Repeat problems; protecting beds and small areas
Mole-Labeled Baits
$100–$300 per application
Baits are not a shortcut; they only work in live tunnels. That is why Downers Grove providers run the flattening test before any bait goes down. Bait in a dead tunnel in Downers Grove is wasted product.
- Time
- 30–45 minutes
- Best for
- Large or hard-to-trap areas; used exactly as labeled
Active-Runway Trapping
$150–$400 per visit; multi-visit plans $300–$900
Trapping is the method most extension services recommend for moles. Traps go over confirmed active runways. They're rechecked within a day or two. Traps that go untouched get moved to fresh Downers Grove runways.
- Time
- 30–60 minutes per visit, over several visits
- Best for
- Most yards; the most reliable method

Main runways often follow edges like beds, walks and fences. That's where traps work best.Which moles live around Downers Grove.
Moles are insectivores, not rodents. They eat earthworms and grubs, not roots. The eastern mole is the one digging up lawns around Downers Grove. It's gray, about six inches long, with big spade-like front feet.
When they tunnel.
Frozen ground in winter sends them deeper. Summer heat and drought also push them down.
Raised ridges are feeding tunnels just under the turf. Many are used once and abandoned.Finding an active tunnel.
If it's raised again, it's active. Main runways often follow edges: walks, fences and beds. Lawns from Downers Grove out to Bolingbrook and Naperville 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 Downers Grove.
- Fall: a second burst near the surface. - Winter: lows near 17°F in Downers Grove. Ground freezes; moles go deep. - Spring: peak tunneling. Best time to trap. - Summer: highs near 84°F in Downers Grove 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?
Moles by the numbers.
For Downers Grove homes, because moles are solitary, several fresh ridges usually mean more than one animal. For Downers Grove 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 Downers Grove 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 Downers Grove 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.
What affects the price
- Season, since spring and fall book fastest.
- Per-mole pricing versus per-visit pricing.
- Number of moles present on the property.
- Buried barriers for raised beds or gardens.
- Mole-labeled bait applications added to trapping.
- Property bordering fields, woods, or streams.

Questions people ask
Is the mole still in my yard?
Step down a short section of tunnel. If it's raised again in a day or two, it's active.
How long does professional mole control take?
Usually one to three weeks of regular trap checks.
How many moles are in my yard?
Usually just one to three.
Will moles come back after they are removed?
New moles can move into empty tunnels. Catching newcomers early keeps damage small.
