Moles can cause severe damage to your lawn, paver patios, gravel beds, and landscaping if left unchecked.

Here at Smith’s Pest Management, we’ve helped thousands of homeowners throughout California remove moles from their property.

In this post, we’re sharing the exact strategies we use in the field for getting a mole-free yard and garden.

What are Moles?

Moles (members of the family Talpidae) are small, burrowing mammals with cylindrical bodies, dark, velvety fur, and powerful forelimbs with large, outward-facing claws.

Common species of moles include the Townsend’s mole, which is widespread along the Oregon and Washington coast, and the broad-footed mole, which we see often in California.

Their close relatives include shrews and hedgehogs.

While you may see mice or ground squirrels darting across your yard, it’s unlikely that you’ll see moles very often. That’s because they spend most of their lives underground, digging constantly in search of food.

Because of this, one of the most obvious signs of mole activity is the presence of raised ridges and mounds of soil in your lawn or garden.

Contrary to popular belief, moles don’t eat the roots of plants and trees, although they do tunnel around and beneath them and create dirt piles in your yard.

Instead, moles are insectivores, so their tunnels are often concentrated in areas with plenty of earthworms and grubs.

The Difference Between Moles and Other Animals

Moles, voles, and pocket gophers all dig and cause damage, but they have several important differences.

If you’re going to get rid of moles, you need to be able to differentiate them from other burrowing critters.

Moles Voles Pocket Gophers
  • Small, cylindrical bodies
  • Velvety fur, typically gray or dark-colored
  • Long, pointed snouts
  • Large, paddle-like front paws made for digging
  • While rats and mice are rodents, moles are mammals that spend most of their lives underground, digging burrows
  • Small, stocky rodents
  • Short legs and tails
  • Brown or gray fur
  • Blunt snouts
  • Medium-sized rodents
  • Fur-lined cheek pouches for carrying food
  • Brown or gray fur
  • Strong, clawed forelimbs for digging
  • Short tails
  • Prefer moist, loamy soil
  • Commonly found in lawns, gardens, and woodland areas
  • Prefer grassy areas and dense ground cover
  • Found in gardens, meadows, and beneath shrubs.
  • Prefer sandy or loamy soil
  • Commonly found in agricultural fields, pastures, and gardens
  • Insectivores
  • Feed on earthworms, grubs, and other soil insects
  • Herbivores
  • Feed on grasses, roots, bark, seeds, and bulbs
  • Herbivores
  • Feed on roots, tubers, and bulbs
Damage Caused
  • Create raised ridges and mounds in lawns and gardens
  • Their mounds are symmetrical and do not feature a dirt plug blocking the opening
  • Excavated dirt will include large chunks of soil
  • Can disrupt plant roots but primarily cause aesthetic damage to turf
  • Create surface runways in lawns
  • Gnaw on tree bark and roots, which can kill plants and trees
  • Can destroy garden vegetables and flowers by eating their roots
  • Create extensive underground tunnel systems
  • Can uproot plants and crops as they search for food
  • Mounds of soil can disrupt the landscape, cause tripping hazards, or make it difficult to mow your lawn

What Attracts Moles to Your Yard?

These pests live their entire lives in their mole tunnels, so they’re more likely to frequent areas that offer the ideal habitat for feeding, breeding, and burrowing.

Here are three environmental factors that moles love:

  • Lots of Insects. Moles eat a lot of bugs. In fact, the NWF reports that many species eat up to 100% of their body weight in insects each day. Studies have shown that a mole’s diet consists of earthworms, white grubs, beetles, and larvae. Moles will construct elaborate burrows in areas where these insects are abundant.
  • Cool Temperatures. Contrary to popular belief, moles are not blind or nocturnal. They’re active throughout the day and prefer moist, cool soil that helps them regulate their temperature.
  • Landscaping Elements. The main runways moles construct tend to follow certain landscaping elements, like fence rows, paths, or other human-made borders. They may also pop up along a line of hedges or another protected area. Moles will also burrow under shrubs and trees to locate the insects that live in their root systems. Wherever moles set up shop, food is the primary motivator—because of this, controlling their food sources is one of the most effective ways to control the mole populations.

Before You Get Started

1. Safeguard toxic materials

If you are using poison to control moles, always store them in an area that is inaccessible to children, pets, and non-target animals, such as a locked cabinet, and ensure they are clearly labeled.

2. Understand and follow product guidelines

Read the labels on all used pesticides and rodenticides thoroughly and adhere strictly to the application instructions provided for your safety and to effectively address the mole problem.

3. Protect yourself

Don personal protective equipment such as safety goggles, gloves, and protective clothing when handling mole baits or removing mole remains after trapping to prevent any direct contact with hazardous substances.

4. Choose your treatment option

Choosing the right way to handle moles can be tricky for homeowners wanting to protect their lawns and gardens.

Compared to other urban wildlife, moles are actually pretty tough to control.

To deal with moles, homeowners have two main options: trapping and baiting.

Other methods exist but aren’t as effective as these options.

Here’s how to select the best option

  • Assess your property size and landscape: Larger properties may require more extensive solutions (like large-scale baiting or trapping programs), while smaller yards might be manageable with less intensive approaches.
  • Evaluate the effectiveness of various methods: Research and compare the effectiveness of different control options, including traps, poisons, and natural deterrents.
  • Professional assistance vs. DIY: Decide whether you want to tackle the problem yourself or hire a pest control professional like Smith’s for quicker and more efficient results.

How to Get Rid of Moles: 5 Effective Ways

1. Traps

Trapping is the most reliable method to get rid of moles.

Modern mole traps, including harpoon traps and scissor-jaw traps, use lethal methods to kill moles and quickly eradicate mole populations.

They also offer a high degree of target-specificity for moles and no potential for chemical buildup or secondary poisoning in the surrounding ecosystem.

Keep in mind that trapping moles requires consistency and creativity.

Moles are smart, and they, more than many other small mammals, are excellent at detecting and avoiding traps that aren’t set or placed properly.

How to do it:

  • To make your trapping efforts as effective as possible, we recommend placing traps directly in active mole runways and trapping during the spring and fall, when moles are most active.
  • Trapping during the spring allows you to eliminate females before they give birth to young, which is an effective way to limit infestations.
  • Use about 3-5 traps per acre of property.
  • If possible, you should seek to place at least one trap in each of the moles’ main runways. Mole runways are pathways the critters use again and again, so setting the traps in or near them improves the efficacy of your trapping program.
  • You can find runways by poking holes into the top of the soil near a mole hole using a stick or your index finger. If the hole is repaired within a day or two, it’s a prime runway and a great place to trap moles.

2. Baits

Baiting involves using poison to kill moles in their burrows.

Generally speaking, there are three different types of mole baits available: grain baits, gel baits, and synthetic worm baits.

They’re not all created equal, though. Here’s what you need to know:

  • Grain pellet bait formulations have shown inconsistent results, since their efficacy is highly dependent on both the area and the mole species present.
  • First-generation anticoagulant chlorophacinone pellet baits can be effective at certain times of the year, but they require repeated applications and may take as long as six weeks to eliminate mole populations.
  • Earthworm-style baits containing the rodenticide bromethalin are generally considered the most effective since these baits can kill moles after a single feeding. Moles who eat earthworm-style baits die about 12-24 hours after a single ingestion. Additionally, earthworm-style baits tend to be enticing to moles since soil invertebrates are the main dietary staples for moles.

One of the benefits of baits is that poisoned moles typically die underground in their tunnels, so you won’t have to find and dispose of their bodies.

How to do it:

  • Repeat bait applications every week for up to six weeks.
  • Consider using high-success bait formulations, like gel baits that contain the anticoagulant ingredient warfarin.
  • If you want a faster-acting bait, look for synthetic worm baits that contain bromethalin, which can kill moles in as little as 24 hours with just one feeding.
  • No matter what kind of bait you use, you can make it as successful as possible by inserting baits directly into mole tunnels.

3. Eliminate mole food sources

When you eliminate the grubs and other insects moles feed on in your yard, you make the habitat less attractive for moles.

We recommend controlling grub populations by using beneficial nematodes or milky spore to kill grubs. If you want faster results, use an insecticide instead.

4. Create dig-proof barriers

To form a human-made boundary around your lawn and garden, dig a trench that is roughly 2 feet deep and six inches wide around the space you’d like to protect.

Fill the trench with rocks or line it with wire mesh or hardware cloth with holes ¾ wide or smaller.

This is a time-consuming but effective, long-term solution to keep moles from burrowing their way into your yard.

You can also install gopher wire or gopher baskets under your lawn and around your newly planted landscaping items to keep moles from digging through the moist soil surrounding the roots.

5. Keep your lawn tidy

Moles feel safest under cover.

Because of this, eliminating their shelter is a great way to encourage them to go elsewhere.

Here’s what to do:

  • Mow Regularly: Keep your lawn well-maintained by mowing often. This improves the appearance and helps prevent moles, as they prefer longer grass.
  • Avoid Overwatering: Don’t overwater your lawn. Excessively moist soil attracts insects and grubs, which moles eat. Water your lawn deeply but not too often.
  • Fill Tunnels: If you see mole tunnels, fill them in right away. This can stop moles from coming back or making new tunnels.
  • Install Barriers: To keep moles out, dig trenches around your lawn’s edges and fill them with rocks or wire mesh.

Remember that most lawns only need about an inch of water per week to stay healthy, so this approach won’t make your outdoor space any less beautiful.

What to Use as a Last Resort: Fumigants

If you’re really struggling to get rid of moles, you can turn to fumigants.

These should only be used when nothing else works, though – they’re highly toxic and will kill pets, animals, and non-target species unless you use them correctly.

Currently, there are two fumigants federally registered to control moles:

Aluminum phosphine tablets and gas cartridges.

That said, fumigation can produce inconsistent results when used to control moles, and there’s no way to confirm that you’ve killed the mole.

To ensure success with fumigation, it’s essential to insert any fumigant you use deep into the mole tunnel, and only to use fumigants when the soil’s moisture content is high enough to contain the gas within the tunnel.

You may also need to apply repeated or large doses of fumigant, which makes this conventional control method drastically more expensive and time-consuming than trapping or baiting.

Methods to Avoid

1. Natural predators

Some people believe that introducing natural predators like owls, hawks, snakes, and domestic dogs and cats can help get rid of moles.

Unfortunately, that’s not a wise approach.

Firstly, natural predators won’t be able to effectively or adequately eliminate a severe mole problem.

Secondly, moles can carry diseases and parasites that can transmit to domestic dogs and cats, so encouraging your pet to face off with moles just isn’t a good idea.

2. Ultrasonic devices

Don’t waste your money on ultrasonic devices. Although these devices may startle moles at first, the moles will quickly get used to them.

Once the moles adapt, they’ll go back to digging, eating, and breeding just like normal.

3. Electromagnetic devices

Like ultrasonic devices, electromagnetic spikes claim to keep moles away, but there’s no research to back that up.

Moles will quickly get used to the presence of these devices and will either learn to avoid them or will start to ignore them completely.

4. Mole repellents

Some people believe that moles dislike plants with strong smells, such as daffodils, marigolds, and anything in the allium family, and that planting these species around the edges of your garden will form a natural barrier that protects your property from the digging pests.

Unfortunately, there’s no evidence to support this.

If you rely on repellent plants to get rid of moles, you’ll just wind up wasting your time, money, and effort and not controlling moles at all!

On the other hand, if you do a quick Google search for “store-bought mole repellents,” you’ll find dozens of products that claim they’ll drive moles out of your yard in a matter of days.

Unfortunately, there’s no formal research suggesting that any of these products actually work.

While we’ve found soil repellents that contain castor oil to provide temporary relief for a few days or weeks, you have to apply them almost daily in quantities sufficient to drench the soil.

This means you’ll wind up spending a ton of money and investing a lot of work into a solution that doesn’t actually resolve your mole problem.

With this in mind, we recommend sticking to proven methods – like trapping, baiting, and exclusion.

How Do Pest Control Pros Deal with Moles?

If DIY is not your style, you may want to call in a professional mole control team like Smith’s.

Here are a few tactics our team here at Smith’s Pest Management uses:

1. No-kill Mole Trapping

Trapping is a sure-fire way to get rid of moles without killing them.

The Smith’s team will inspect your yard, identify the most active mole runways, and place no-kill traps accordingly.

This option reduces your existing mole problem, and when you opt to participate in our annual mole control program, it can prevent moles from coming back in the future.

Since moles get very active in the winter when soil moistens up, good mole control is best done with trapping or Talpirid worms.

2. Grub Control

Eliminate the moles’ food source – eliminate the moles!

Smith’s provides comprehensive grub control services for property owners with excess insect populations.

Because we use a granular lawn treatment, this option is fast, easy, and straightforward.

3. Exclusion

A popular, humane, no-kill method of mole control, exclusion relies on techniques that make it difficult for moles to enter your yard.

Gopher baskets and gopher wire can be particularly useful. While Smith’s does not provide mole exclusion services, the team can advise you on the methods that may work for you.

4. Annual Mole Control

It’s hard to get rid of moles forever. That’s why we recommend participating in our

annual mole control program.

Each year, we’ll return to your property and help address and eliminate ongoing or recurring mole problems.

This is the most effective way to maintain a healthy, green lawn for years to come.

Professionals like Smith’s Pest Management know how to get rid of persistent moles that keep coming back to your yard.

What does mole damage look like?

While mole damage may seem similar to the damage caused by voles, mice, or rodents, some key differentiators exist.

Here are five signs to look for:

  • Dead Grass. As we mentioned in a previous blog on the topic, patches of dead grass are a good indication that you have a mole problem. As these pests dig mole tunnels, they disrupt the root systems of nearby grasses, killing the grass at surface level and leaving dead patches in their wake.
  • Molehills. Have you ever heard the saying, “making a mountain out of a molehill?” When moles dig their tunnels, they act like mini excavators, moving all that dirt out of the mole tunnel and up to the surface, creating a telltale, mounded molehill at the tunnel entrance.
  • Mounds That Are Far Apart. Moles aren’t the only creatures that make entrance and exit mounds. Gophers do something similar. However, the difference is that gopher mounds are close together, while molehills tend to be about six feet apart.
  • Chunks Of Dirt. When gophers dig in your yard, they pulverize the soil into a smooth powder. Moles, on the other hand, dig the earth up in chunks. As you evaluate the mounds in your yard, look for clumps of soil, which is a surefire sign of moles. If you’re wondering whether you have moles in your landscaping, it’s equally important to know what not to look for. Since moles are insectivores, they don’t chew plants or root systems. Instead, they eat earthworms, grubs, and centipedes. If you notice gnaw marks on your garden plants or vegetables, it’s likely that voles or mice are responsible – not moles.
  • Surface Runways. Surface runways are feeding tunnels that moles create just below the surface of the soil. Usually, they look like raised ridges in a lawn area where moles are present. They typically do not have mounds attached to them. Thanks to their proficient digging abilities, moles are capable of digging up to 100 feet of surface runways each day. While moles travel through some of their surface runways every day, others are only used for occasional feeding.

What is the fastest way to get rid of moles?

The fastest way to get rid of moles is through trapping. Live or kill traps remove mole populations rapidly and are excellent ways to deal with even a severe mole problem.

If you want an even more rapid solution, pair trapping with other methods, such as exclusion and deterrents.

How do I get rid of moles humanely?

You have many options if you want to get rid of moles without killing them.

Live traps contain moles without harming or killing them and allow you to release the rodents a safe distance from your property.

Other integrated pest management (IPM) techniques focus on exclusion (using wire mesh buried underground deter moles and prevent digging), store-bought repellents (planting mole-repellent plants and eliminating mole food sources), and habitat modification (creation of artificial drought and trench digging, for example) to get rid of moles humanely and effectively.

What home remedy will kill moles?

There’s no home remedy that will effectively and humanely kill moles.

Instead of focusing on home remedies, focus on proven control methods like trapping and baiting.

Can you flood moles out?

While some people recommend trying to flood moles out of their holes using hoses or buckets of water, we advise against it. 

This approach will only damage your lawn and loosen the dirt beneath your grass, making it easier for moles and other pests to burrow into. Additionally, moles can simply take shelter above ground until the water recedes, making this tactic ineffective.

Instead, opt for a proven mole-control method, like one of the IPM approaches we listed above.

What time of day are moles most active?

Although moles are active throughout the day, their activity levels peak around noon and midnight.

They also tend to be active after a warm, soaking rain, when the insects they eat are most active.

Is it legal to kill moles?

Yes. Moles are not classified or protected in any way, and it is legal to trap or kill moles on your property when they are causing damage.
