Getting rid of moles in your yard can be a daunting task, but HOW.EDU.VN is here to provide expert advice and solutions. We will guide you through effective methods to eliminate these pesky creatures and prevent them from returning, ensuring your lawn remains pristine and healthy. Our expert guidance will help you reclaim your yard and keep it mole-free. Dealing with mole problems can be frustrating, but our network of PhDs offers proven strategies.
1. Understanding Mole Activity in Your Yard
Identifying active mole tunnels is the first step in effectively managing these critters. Look for specific signs to differentiate between occasional foraging and established pathways.
1.1. Identifying Active Mole Tunnels
Look for longer, straighter ridges that moles keep rebuilding when you pierce or flatten them. These are tunnels that moles use multiple times and provide the best chances to trap a mole. Avoid short, twisting ridges close to each other – these are feeding tunnels that moles only use once or twice.
To check if the traveling tunnels are active:
- Flatten the ridges by walking on them or pulling a lawn roller over the grass, mulch, or soil.
- Or, make a hole in each tunnel using a stick or a finger.
- Return the next day and check the ridges. Where the moles have been, the ridges are back, and the holes are fixed. Those are the active tunnels.
Now that you’ve identified active mole tunnels, you can try some of these control methods.

1.2. Differentiating Between Mole Tunnels and Runs
Understanding the difference between mole tunnels and surface runs is crucial for effective mole control.
| Feature | Mole Tunnels | Surface Runs |
|---|---|---|
| Appearance | Deep, well-defined ridges | Shallow, barely raised pathways |
| Purpose | Used for travel and hunting; actively maintained | Temporary foraging paths, often abandoned after a single use |
| Location | Typically found deeper in the soil, often following a relatively straight path | Located just beneath the surface, characterized by a twisting and erratic pattern |
| Persistence | Rebuilt quickly when disturbed, indicating active use | Collapse easily and are not usually repaired, suggesting infrequent or past use |
| How to spot | Look for straight lines and minimal curves. | Observe closely, most of the time they would be feeding tunnels that moles only use once or twice. |
2. Effective Mole Removal Methods
Several methods can help you get rid of moles in your yard, each with its own advantages and disadvantages. Choosing the right approach depends on your specific situation and preferences.
2.1. Using Gummy Baits
Worm and grub-shaped gummy baits can kill moles 12 to 24 hours after ingestion.
Poisoned baits are a good option if you’re looking for an easy way to kill the moles in your lawn. Moles die in their burrows 12 to 24 hours after ingestion, so you don’t have to touch or relocate the animal.
Moles are not rodents, so classical rodent baits (seeds, pallets, etc.) do not attract them.
How to use mole baits:
1. Put on gloves when you handle bait to avoid getting poison on your skin and leaving your scent on the bait.
2. Choose 3 to 4 active tunnels across the lawn.
3. Poke a small hole into the ridge with a stick.
4. Place a single piece of bait inside each tunnel.
5. Cover the hole with dirt and grass.
6. Wait for a few days.
7. Repeat these steps if molehills and ridges still appear.
Pro tip: The best time to place mole bait is after a light rain or irrigation. Moles hunt when the soil is damp.
What are the best mole baits?
Gummy baits looking like worms or grubs – mole’s favorite snack – are the most effective options. Here are a few examples available for purchase online:
| Bait Type | Active Ingredient | Advantages | Disadvantages |
|---|---|---|---|
| Worm Gummy Baits | Bromethalin | Mimics natural food source, effective, easy to use | Toxic to non-target animals, requires careful handling |
| Grub Gummy Baits | Zinc Phosphide | Quick kill, attractive to moles | Can be dangerous to pets and wildlife, needs precise placement |
| Gel-Based Baits | Warfarin | Can be applied directly into tunnels, effective for large infestations | Requires multiple applications, slower kill rate |
| Fake Worm Baits | Not Applicable | Often contain iron phosphate and is effective for killing lawn pests and grubs, making it a food source for moles | Moles may not recognize them as food, reducing effectiveness |
| Talpirid Mole Bait | Bromethalin | Contains a mix of ingredients that mimics a mole’s normal diet. | It will not be as effective if the moles have a food source already. It is also extremely toxic to other animals and needs to be used with caution. |
2.2. Trapping and Releasing Moles
Traps installed correctly along active tunneling can help you get rid of moles fast and permanently.
There are several types of mole traps. Humane or live catch traps are often metal cages or plastic cylinders that allow moles to enter but prevent them from exiting.
Note: Trapped moles need to be relocated to a new habitat. Check your local regulations regarding wildlife relocation. To avoid having to do it yourself, you can always call a local wildlife relocation service.
These traps require digging and are often installed in the tunnel below a freshly built molehill (one that recently appeared on your lawn). Here’s how to install a humane trap:
- Shovel the molehill dirt away and dig down until you see the entry into a horizontal tunnel.
- Place the trap with the opening toward the tunnel entry.
- Cover back with dirt.
- Place a bucket on top to make sure no light creeps in.
- Check every few hours, especially if it’s summer. Trapped moles can die of heat and dehydration.
Among the traps that kill the moles instead of capturing them, scissor traps and harpoon traps are the most effective and easy to use.
2.2.1. How to Install Scissor Traps
A scissor trap, also known as Victor out-of-sight mole trap, looks like two scissors stuck together by a metal rod. To install it:
- Press the handle to open the scissors. Engage the latch to keep the trap open while you install it.
- Push the trap into the ground over the tunnel so the two scissors straddle it.
- Press the soil beneath the trigger with your finger so a small dirt wall blocks the tunnel.
- Release the latch.
- Place a bucket over the trap. This will remind you to check the trap daily and prevent light from entering the tunnel.
2.2.2. How to Install Harpoon Traps
Also known as plunger traps, harpoon traps look like tall, skinny frames with sharp spikes pointing down and a strong spring that pushes the spikes when the trigger is activated. To install it:
- Pull the handle up to raise the spikes and arm the spring.
- Press the ridge with your feet to push dirt inside the tunnel and create an obstacle.
- Push the trap into the ground above the pressed soil with the stakes and trigger standing on the soil.
- Place a bucket over the trap. This will remind you to check the trap daily and prevent light from entering the tunnel.
| Trap Type | Mechanism | Advantages | Disadvantages |
|---|---|---|---|
| Scissor Traps | Scissors-like blades triggered by soil disturbance | Effective, relatively easy to set | Can be dangerous to pets and children, requires careful placement |
| Harpoon Traps | Spring-loaded spikes that pierce the mole | Immediate kill, effective in active tunnels | Requires significant force to set, can be difficult to position correctly |
| Humane/Live Traps | Cage traps that capture moles without harming them | Non-lethal, allows relocation of moles | Requires frequent monitoring, moles must be relocated to a suitable habitat |
| Mole Tunnel Traps | Placed directly in tunnels, these traps capture moles as they pass | Effective in intercepting moles using established pathways | Requires precise placement within the tunnel system, can be time-consuming to set up |
2.3. Mole Repellents
Castor oil-based repellants can drive moles off your property but are a temporary solution.
Castor oil is supposed to drive away moles with its foul smell. The oil also triggers digestive problems if it gets on the insects moles eat or the mole’s fur, which they clean by licking. You’ll find mole repellants in granular and liquid form and as round pellets imbibed with repellant.
How to spread mole repellents on your property:
- Identify active tunnels.
- Plan a way out for the moles; otherwise, they’ll remain in your yard.
- Put on some gloves.
- Start the application with the area where you spot active tunnels. Treat another section of the lawn every day going toward the exit area.
- Repeat the application after a month or two (check product instructions). Otherwise, moles might return.
Mole repellents with castor oil are usually safe for pets and children, but it’s a good idea to be careful when applying. Keep them off the lawn while you spray for moles.
Note: You can make a DIY castor oil repellent by mixing 6 ounces of 100% castor oil with 2 tablespoons of dish soap and 1 gallon of water. Dilute 1 ounce of solution into 1 gallon of water and use it on the lawn.
| Repellent Type | Active Ingredient | Advantages | Disadvantages |
|---|---|---|---|
| Castor Oil-Based | Castor Oil | Safe for pets and children, non-toxic | Can be temporary, needs reapplication after rain |
| Granular | Varies (e.g., garlic) | Easy to spread, long-lasting | May not be as effective in heavy infestations, can have a strong odor |
| Liquid | Varies (e.g., peppermint) | Can be applied directly to tunnels, good for spot treatment | Requires frequent application, can wash away easily |
| Electronic | Ultrasonic sounds | Often solar-powered and water-proof | Not always effective due to the differing soil composition |
3. Long-Term Mole Prevention Strategies
Preventing moles from returning to your yard involves several strategies focused on making your property less attractive to them.
3.1. Physical Barriers: Digging a Trench
Trenches about 2 feet deep filled with gravel, rocks, or fence mesh can stop moles from entering small planted areas.
This method is costly and time-consuming, so most homeowners only use it to protect valuable sites such as vegetable gardens or ornamentals. However, protective tranches are long-lasting and also keep the plants safe from gophers, rabbits, mice, and other garden critters.
Here’s how to dig a trench to keep moles away:
- Dig a trench 2 inches wide and about 2 feet deep around the area you want to keep moles out of.
- Fill it with rocks or gravel – moles can’t dig through hard material.
- Cover the trench with soil.
You can seal the area by inserting a wire fence into the trench. Experts from the University of Nebraska-Lincoln recommend aluminum sheeting or ¼-inch mesh galvanized hardware cloth. “Bury to a depth of 24 to 30 inches and allow 6 inches to extend above the ground surface.”
Bending out the base of the fence about 4 inches at a 90-degree angle can discourage moles from digging deeper.
Note: Trenches are not bulletproof. Stubborn or very hungry moles might dig deeper.
3.2. Reducing the Food Source
Reducing the food source can make your yard less attractive to moles, but it won’t banish them from your property alone. You also need traps, baits, or repellants.
This strategy is less effective because the moles’ diet is 70% to 90% earthworms, which are essential for soil health. Reducing the earthworms in the soil enough to make the moles leave might be more damaging for the lawn than the moles.
However, you can control other lawn bugs moles like to eat (white grubs, armyworms, ants, mole crickets, snails, slugs, Japanese beetles) and turn your yard from a rich buffet into a poorly supplied supermarket.
| Strategy | Description | Advantages | Disadvantages |
|---|---|---|---|
| Trenching | Creating a physical barrier around vulnerable areas by digging a trench and filling it with rocks or wire mesh | Long-lasting, effective in protecting specific areas | Costly, labor-intensive, may not be practical for large areas |
| Reducing Food Source | Controlling lawn pests such as grubs, armyworms, and ants to make the yard less attractive to moles | Environmentally friendly, improves overall lawn health | May not completely eliminate moles, requires ongoing maintenance |
| Soil Management | Improving soil drainage and avoiding overwatering to reduce the attractiveness of the soil to moles | Prevents soil compaction, promotes healthy grass growth | Requires consistent monitoring and adjustments, may not be effective during periods of heavy rainfall |
| Selecting Deterrent Plants | Planting mole-deterrent species like daffodils, marigolds, and alliums | Natural, adds aesthetic value to the yard | Effectiveness varies, may not work in all situations |
4. Alternative Methods: Weighing the Options
When dealing with mole infestations, several alternative methods are often suggested. However, it’s crucial to understand their effectiveness and potential drawbacks.
4.1. Mole-Deterrent Plants
Plants like daffodils, marigolds, alliums (garlic, shallots), caster oil beans, and Euphorbia lathyris (mole plant) are said to deter moles either because of their odor or because they repel insects and reduce their food source. However, there is no scientific evidence to support this.
4.2. Scare Tactics
Lawn moles are difficult to frighten because they are already exposed to heavy lawn equipment, sprinklers, and people traffic. When these devices work, the effect is only temporary until moles get used to them.
4.3. Mole Predators
Dogs and cats can effectively dig out and catch moles, but they might tear the yard apart. You can also install high perches, birdbaths, and bird feeders to attract hawks, owls, and other natural mole predators.

4.4. Fumigants
Using fumigants to kill moles is illegal in some states, and even where allowed, they have little effect outdoors, where the gas is easily dispersed.
“Moles naturally exist in a low oxygen environment and can easily wait for the fumes to dissipate in the tunnels,” says Rebecca McPeake, professor and extension wildlife specialist at the University of Arkansas.
4.5. Mothballs
Mothballs are a popular folk remedy for moles and other garden pests, but they are not your best choice. They are less effective and more toxic than castor oil repellants.
These insecticides kill cloth moths and other fabric insects. They contain high amounts of naphthalene or paradichlorobenzene – dangerous chemicals that release toxic gases. That’s why mothballs are regulated by the United States Environmental Protection Agency (EPA) and should only be used as the product label indicates.
Typically, you place mothballs in tightly closed containers with the infested clothing to concentrate the gases and avoid inhaling them. When used out in the open, mothballs are less effective and can accidentally harm people, pets, or wildlife that may touch, eat, or breathe in their vapors.
Mothballs are also harmful to the environment. Paradichlorobenzene persists for up to 31 days, binds to the soil, and can end up in plants and groundwater.
| Method | Description | Effectiveness | Drawbacks |
|---|---|---|---|
| Mole-Deterrent Plants | Using plants that are believed to repel moles | Limited to no scientific evidence of effectiveness | May not work, relies on anecdotal evidence |
| Scare Tactics | Employing ultrasonic devices or vibration stakes | Moles quickly adapt, rendering these methods ineffective over time | Temporary solution at best, moles habituate quickly |
| Mole Predators | Encouraging natural predators like dogs, cats, hawks, and owls | Can help but may cause damage to the yard or be impractical | Dogs and cats can damage the yard, attracting predators may not be feasible |
| Fumigants | Using gas to kill moles in their tunnels | Often illegal and ineffective outdoors due to gas dispersion | Illegal in some areas, ineffective due to low oxygen environment in tunnels |
| Mothballs | Popular folk remedy involving naphthalene or paradichlorobenzene | Less effective than other repellents and toxic to people, pets, and wildlife | Harmful to the environment, regulated by EPA, poses health risks |
5. Preventing the Return of Moles
To prevent moles from returning:
- Avoid thick mulch and exposed compost piles: These are magnets for moles. If you’re making your own compost, try using enclosed bins.
- Correct drainage issues: If you find areas where water collects, it may be time to level your lawn. It will save damage in the long run and won’t attract moles to the soft ground and bugs.
- Keep lawn bugs under control: Grubs, ants, armyworms, and other lawn pests make your yard more attractive for moles. Use milky spores, beneficial nematodes, and insecticides to reduce their number.
- Avoid overwatering: Moles prefer moist soil, which is easier to dig and attracts insects and earthworms.
