Homeowners in Gretna 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 Gretna 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
Good mole work is mostly finding the right tunnel. The provider maps the runway network in Gretna, flags the active sections, and picks two or three trap points. That map also becomes the baseline for follow-up visits in Gretna.
- Time
- 45–90 minutes
- Best for
- Every job; trapping fails without it
Follow-Up Monitoring
$50–$150 per visit; often included in plans
Some Gretna providers offer seasonal monitoring for properties that border open land. It is priced per visit or as a yearly plan. For Gretna homeowners with recurring moles, that is often cheaper than starting fresh each year.
- Time
- 20–30 minutes per visit
- Best for
- Every trapping job; confirms the yard is clear
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 Gretna lawn with no grubs can still host them. Around Gretna, 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 Gretna providers run the flattening test before any bait goes down. Bait in a dead tunnel in Gretna is wasted product.
- Time
- 30–45 minutes
- Best for
- Large or hard-to-trap areas; used exactly as labeled
Prices are typical published ranges. Ask what’s included before you compare quotes.
Hardware cloth buried around beds keeps moles out of the places you care about most.Which moles live around Gretna.
They eat earthworms and grubs, not roots. Moles are insectivores, not rodents. It's gray, about six inches long, with big spade-like front feet. The eastern mole is the one digging up lawns around Gretna.
When they tunnel.
Mild winters keep them near the surface. 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.
Lawns from Gretna out to New Orleans and Kenner show the same pattern. Main runways often follow edges: walks, fences and beds. If it's raised again, it's active. Check it in a day or two. Step down a short stretch of tunnel and mark it. Look for fresh ridges and mounds after rain.
A year of moles in Gretna.
- Spring: peak tunneling. Best time to trap. - Winter: mild in Gretna. Moles stay active. - Fall: a second burst near the surface. - Summer: highs near 91°F in Gretna push moles deeper.
Mole, gopher or vole?
- Mole: raised ridges and round, volcano-like mounds. - Damage: moles don’t eat plants; gophers and voles do. - Vole: surface runways and small holes in the grass. - Gopher: crescent-shaped mounds with a plugged hole.
What works, and what doesn’t.
- Works: traps set in active runways. - Rarely alone: grub control, since they mostly eat earthworms. - Rarely: castor oil, sonic stakes, gum or flooding. - Sometimes: labeled baits, used deep in tunnels.
Protecting garden beds.
Bend the bottom edge outward. Bury quarter-inch hardware cloth around beds, about two feet deep. It's work up front, but it lasts for years. Raised beds can get a mesh floor before you fill them.
Lawn care that helps.
Constantly wet lawns draw earthworms, and moles follow. Water deeply but less often. Grub control alone rarely moves moles on. Healthy turf recovers from tunnels faster.
Signs the problem is over.
- No new mounds for two weeks. - New ridges? Another mole may have moved in. - Traps stay untouched for several checks. - Stepped-down runways stay flat.
Choosing a trap.
- Scissor traps: set straddling an active runway. - Rules: check what your state allows first. - Placement: main runways beat fresh feeding ridges. - Tunnel traps: sit inside a dug-out runway. - Harpoon traps: set on top of a pressed-down ridge.
Mole myths.
- Chewing gum in tunnels: no evidence it works. - Flooding tunnels: they just dig new ones. - Many mounds, many moles: usually it’s one or two. - Moles eat bulbs: no, voles using their tunnels do. - Castor oil: may move them briefly, not away.
Moles aren’t all bad.
They eat grubs and other insect larvae. Moles loosen and aerate soil. In a front lawn or garden, most people want them gone. A mole in a field may be fine to leave.
Fixing the lawn afterward.
Rake mounds flat and step ridges down. Wait until the mole is caught. Overseed bare spots in spring or fall. Water to settle the soil.
Moles, kids and pets.
Keep kids and pets away from traps. Moles don't bite unless handled. Digging dogs can wreck a lawn faster than moles. Baits must go deep in tunnels, exactly as the label says.
What a mole visit looks like.
They test which runways are active. The tech walks the lawn and maps the tunnels. They check traps every day or two. Traps go into the main runways.
Moles, voles or gophers?
- Moles: raised ridges and round, volcano-shaped mounds. - Chipmunks: small clean holes with no soil around them. - Gophers: crescent-shaped mounds with a plugged hole. - Voles: narrow surface runways through the grass.
Watering and moles.
Water deeply and less often instead of a little every day. Moles follow moist soil, where worms rise near the surface. Fix leaky sprinklers that leave soggy corners.
Flower beds and borders.
Plants wilt when their roots are left hanging in air pockets. Moles tunnel under beds looking for worms, not to eat plants. Press tunnels down firmly and water to settle the soil.
Questions to ask before you sign.
- Is it a mole, gopher or vole? - Is lawn repair included? - What if another mole moves in? - How often will you check traps? - Which method will you use?
Moles by the numbers.
Around Gretna, 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. Around Gretna, because moles are solitary, several fresh ridges usually mean more than one animal. Around Gretna, tunnels often run just under the surface, with deeper nesting chambers below, and a single mole can maintain an extensive system across a yard. Around Gretna, moles do not eat plants; they tunnel for earthworms, grubs, and soil insects, and the ridges they leave behind are what most people notice.

Questions people ask
Do ultrasonic mole repellers work?
Around Gretna, moles have poor eyesight and live almost entirely underground, where airborne sound barely reaches them. Around Gretna, if you try a sonic stake, watch for fresh ridges over two weeks; if activity continues, switch to traps in the active runs. No. Around Gretna, there is no scientific evidence that ultrasonic or vibrating devices repel moles, and extension offices consistently advise against relying on them.
Are moles rodents?
They're insectivores, related to shrews. They eat earthworms and grubs, not plant roots. No.
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 many moles are in my yard?
Usually just one to three.
Should I repair the lawn before or after trapping?
After. Fixing it first hides the tunnels you need to find.
Do homeowners prefer DIY mole trapping or hiring a pro?
Around Gretna, many homeowners try trapping themselves first because it is the cheapest option and traps are sold everywhere.
