The short version
To control moles, trapping is the most effective method. Moles are insectivores that tunnel for earthworms and grubs.
- Moles eat earthworms and grubs, not plant roots.
- Surface ridges and volcano-shaped mounds are classic signs.
- Trapping is the most reliable control method.
- Spring and fall are peak seasons for mole activity.
For homeowners and property managers in the United States who are dealing with active mole infestations and want a clear, actionable plan.
What to look for
While moles are beneficial in aerating soil and eating pest insects, their tunneling destroys lawns, gardens, and landscapes. The damage is most visible in spring and fall when soil is moist and earthworms are near the surface. In mild climates, moles can be active year-round, compounding the problem. Moles are solitary, territorial mammals that live underground. They dig two types of tunnels: shallow surface tunnels (ridges) for feeding and deeper runways for nesting and storage. A single mole can create hundreds of feet of tunnels in a week.
- 1Raised surface ridges that crisscross the lawn.
- 2Volcano-shaped mounds of soil (molehills) at tunnel entrances.
- 3Spongy, soft areas underfoot where tunnels have collapsed.
- 4Wilting or dead patches of grass due to root damage from tunneling.
- 5Increased tunneling activity after rain or irrigation.
- 6Visible molehills in gardens, flower beds, or near foundations.
Why it’s worth acting soon
- Tunneling can damage grass roots, leading to dead patches.
- Mounds can smother grass and create trip hazards.
- Mole tunnels can attract other pests like voles and mice.
- Lawn repair costs increase with the extent of damage.
- Mole populations can grow if multiple moles are present.

Round, volcano-shaped mounds come from deeper mole tunnels. Gopher mounds are crescent-shaped with a plugged hole.Understanding Mole Behavior and Biology.
Moles are solitary except during breeding season in late winter/early spring. Females give birth to 2-5 young after a 6-week gestation. Young moles disperse in late spring, often leading to a sudden increase in visible damage. Understanding these habits is key to effective control. Moles are insectivores, not rodents. Their diet consists almost entirely of earthworms, grubs, and other soil insects. A mole can tunnel constantly to find food, which drives its constant tunneling. They have poor eyesight but excellent senses of touch and smell. they can store extra earthworms, allowing them to store live prey in underground chambers for later consumption. This behavior explains why multiple fresh worms are often found in mole tunnels.
Why Trapping Is the Gold Standard.
Both require placement in active surface tunnels. To identify active tunnels, flatten a section of ridge and check 24 hours later: if it's raised again, it's active. Traps should be set in the morning and checked daily. Many states require trapping be done by pest control pros due to regulations and humane considerations. Professional trappers often use multiple traps and rotate locations to ensure complete removal. The typical success rate for professional trapping is 95% or higher. Trapping remains the most reliable and environmentally sound method for mole control. Unlike poisons, traps do not pose a risk to pets, children, or non-target wildlife. The two main trap types are scissor-jaw and harpoon (spear) traps.
Moles have big, spade-like front feet built for digging. They eat earthworms and grubs, not plants.The Role of Grub Control and Other Myths.
Earthworms are beneficial for soil health, and killing them is neither practical nor advisable. Grub control treatments (like milky spore or beneficial nematodes) may reduce one food source, but moles will simply shift to eating more earthworms. Similarly, ultrasonic devices, vibration stakes, and chewing gum are ineffective. The only proven method for removing moles is physical removal through trapping. Some homeowners try flooding tunnels or using smoke bombs, but these methods rarely work and can damage the lawn. A common misconception is that eliminating grubs will get rid of moles. While grubs are part of a mole's diet, earthworms are their primary food source.
Mole ridges vs. other lawn damage.
Mole tunnels leave raised, linear ridges just under the surface, and the soil has no obvious entrance hole because moles are nearly always underground. That distinguishes them from gopher mounds, which are fan-shaped with a plugged entrance, and from voles, which leave shallow surface runways through the grass. Identifying the ridges correctly is what keeps you from treating for the wrong animal.
What a mole control job should cost.
Mole control is priced by how many active tunnels there are and how much ground the animal is using, not by how many animals you can count. In Emergency Mole Control, a small yard with one or two active tunnels is a small job; a large lot with tunneling across a wide area costs more because it takes more traps and more return visits. In Emergency Mole Control, ask for a written quote that spells out the number of visits, the method, and what the follow-up covers, rather than a single flat number.
Why mole problems come back after removal.
Moles are solitary, but the space they leave is quickly filled by the next animal that moves in from neighboring yards or open ground. That is why removal alone rarely holds: if the food and the tunnel access are still there, a new mole will simply re-colonize the same tunnels. The long-term fix pairs removal with habitat changes, like limiting the grubs and earthworms moles feed on and keeping nearby overgrown areas trimmed, so your yard stops being the easiest target on the block.
What affects the price
- Size of the yard and number of active tunnels.
- Severity of infestation (single mole vs. multiple).
- Accessibility of tunnels (open lawn vs. landscaped areas).
- Type of control method (trapping vs. baiting vs. exclusion).
- Regional labor rates and travel fees.
- Seasonal demand (spring and fall are peak).

What's your biggest frustration with moles?
When to call for help
A single mole can dig up to long stretches of new tunnel. Professionals have the experience to identify active tunnels, set traps correctly, and ensure complete removal. If you've tried DIY methods for two weeks without success, or if you see multiple fresh mounds each day, it's time to call a professional.
What you can do yourself
Many homeowners fail because they set traps in inactive tunnels or use the wrong trap type. DIY trapping can be effective for a single mole in a small yard, but it requires patience, proper trap placement, and daily monitoring. For large yards or multiple moles, professional trapping is almost always the better choice.
Where you live matters
Both species cause similar damage and require the same control methods. Mole activity varies across the United States. In the Northeast and Midwest, moles are most active from March to June and again from September to November, coinciding with earthworm activity in moist soil. Homeowners in these regions should watch for fresh ridges after spring rains. In the Pacific Northwest, where soil stays moist year-round, moles can be active any time, with a peak in spring. Southern states like Texas and Florida see year-round activity, though tunneling slows during hot, dry summers. Regardless of region, the eastern mole (Scalopus aquaticus) is the most common species east of the Rockies, while the Townsend's mole (Scapanus townsendii) is prevalent in the West Coast.
Simple ways to keep moles away
- Reduce soil moisture by improving drainage and avoiding overwatering.
- Maintain a healthy lawn to minimize earthworm and grub populations (though eliminating all earthworms is not recommended).
- Install underground fencing (hardware cloth) around gardens and flower beds.
- Remove thatch and aerate soil to discourage tunneling.
- Apply castor oil-based repellents regularly after rain.
- Keep grass cut short to make surface tunneling less attractive.
Ask what the quote covers if another mole moves in after the first one is caught.Did you know?
Moles can eat a large amount of insects every single day—that's equivalent to a human eating 150 pounds of food daily.
A mole's can store extra earthworms, allowing the mole to store them alive in underground larders for later consumption.
Moles have an extra thumb (a sesamoid bone) on each front paw, helping them dig with incredible efficiency.
Questions people ask
Do moles eat plant roots?
They do not eat plant roots. Damage to roots is caused by their tunneling, which can dry out roots and expose them to air. No. Moles are insectivores and feed primarily on earthworms and grubs.
How fast can a mole dig?
A mole can maintain an extensive tunnel system in suitable soil. In one day, a single mole can create over 100 feet of new tunnels.
What is the best way to get rid of moles?
Trapping is the most effective method. Use scissor-jaw or harpoon traps placed in active surface tunnels.
When is mole season?
Mole activity peaks in spring and fall when soil is moist and earthworms are near the surface. However, in mild climates, moles can be active year-round.
Are moles dangerous to pets or humans?
They can carry fleas and ticks but rarely transmit diseases to humans. Traps and poisons can be hazardous if not used properly. Moles are not aggressive and avoid contact.
How much does professional mole control cost?
Professional trapping programs typically range from $150 to $450 depending on the size of the property and severity of the infestation.
Can I use poison to kill moles?
Poison baits are available but are less effective and can harm non-target animals like pets and wildlife. Trapping is safer and more reliable.
Will getting rid of grubs eliminate moles?
Moles primarily eat earthworms, so eliminating grubs alone won't remove their food source. Grub control may reduce one food source but is not a standalone solution. Not necessarily.
Do ultrasonic mole repellers work?
In Emergency Mole Control, moles have poor eyesight and live almost entirely underground, where airborne sound barely reaches them. In Emergency Mole Control, if you try a sonic stake, watch for fresh ridges over two weeks; if activity continues, switch to traps in the active runs. No. In Emergency Mole Control, there is no scientific evidence that ultrasonic or vibrating devices repel moles, and extension offices consistently advise against relying on them.
