The best mole repellent for most lawns is a castor oil granule, which makes treated soil unpleasant to feed in and moves moles along rather than killing them. Read the damage first, though, because voles are a different animal and call for exclusion and trapping instead. When a mole will not leave, extension guidance points to a trap set in an active runway.

Start with the animal, not the product. Moles are insectivores, related to shrews. They eat grubs, beetle larvae and earthworms, 70 to 100 percent of their body weight a day, and they do not eat bulbs or roots. Voles are rodents. They eat bulbs, roots and bark, and they move straight into a mole's tunnels, which is how the mole gets blamed for the tulips. A large share of what sells as mole repellent is aimed at the wrong animal for the damage in front of the buyer. And if the rodents are in the house, garage or shed rather than the lawn, that is a mouse job: our mouse repellent guide covers sealing them out and trapping them. If squirrels are the ones raiding the bird feeder, our squirrel-proof bird feeder guide covers the feeders and baffles that stop them.

The two peak at different times, too. Moles are busiest in spring and fall, when soil is moist and worms sit near the surface. Vole damage peaks in late winter under snow cover, when they work unseen and bark is the only food left, and you do not see it until the melt. Fall is the season to act on both, before the ground closes and before the bulbs go in.

One thing before the list: we make digging tools, not repellents, so nothing here is ours. Each pick is judged on what its own label claims, what the extension literature supports, and whether it addresses the animal doing the damage.

Mole and vole repellents at a glance

Mole or vole? Read the damage

Buy for the animal you have. The two leave signatures that are easy to tell apart, and getting this wrong is the most common reason a repellent seems to fail.

You can have both, and often do, because voles take over the tunnel network a mole built. Ridges plus chewed bulbs is two problems: castor oil for the mole, exclusion for the vole. Ridges alone mean the mole is the only tenant, and your bulbs were never at risk.

Do mole and vole repellents actually work?

Partly, and it is worth being precise about how. Castor oil is the active ingredient in nearly every granular mole repellent sold in the United States. The accepted explanation is that it coats the soil and the earthworms in it, making the mole's food unpalatable, so the mole leaves treated ground for untreated ground. It repels. It does not kill, and it does not clear a property.

Castor oil also sits on the federal list of minimum risk pesticide ingredients, which is why these products reach the shelf without the registration and efficacy review a conventional pesticide goes through. Penn State Extension's mole guidance puts it bluntly: there are no chemical repellents registered for use on moles, and the electronic and vibrating stakes sold alongside them have never been shown to work. Nebraska Extension is the kinder read, describing castor oil products as showing minor effectiveness against the eastern mole, with one trial holding activity down in a treated area for over 30 days.

So set the expectation correctly. A castor oil granule is a reasonable first move that often pushes moles out of the part of the yard you care about for a few weeks. It is a relocation, not a solution, and it needs reapplying. Repellents do even less for voles, because a hungry rodent in winter is not easily talked out of a bulb, which is why Penn State's vole guidance leads with exclusion and trapping.

How to apply castor oil granules so they hold

Confirm the mole is active first. Flatten a section of tunnel with your foot, mark it, and check in 24 hours. If it has been pushed back up, that run is in use. If nothing moves in a day or two, the mole has already gone.

Then treat area, not tunnels. These are broadcast products, so spread the granules over the whole zone you want protected rather than dribbling them along the ridges, and water them in so the oil reaches the root zone where the worms are. A quarter to half an inch is enough. Re-treat the perimeter as well, since untreated boundary ground is how a mole walks back in.

Reapply after heavy rain and on the label's schedule through the active season. Existing ridges stay visible either way, because a ridge is a hole in the soil, not a living thing. Firm them down with your foot once the mole has moved on.

What is the best mole killer for a lawn?

A trap set in an active tunnel. Penn State Extension calls trapping the most successful and practical method of controlling moles, and Nebraska Extension calls it the most effective and practical means, with success highest in spring and fall, especially after rain. Poison is the weaker route for an animal that lives on earthworms and insects: Nebraska notes that moles rarely eat grain based baits, and Penn State that they do not readily take poisoned baits.

Penn State names three common designs: the harpoon trap, the scissor jaw trap and the choker loop trap. The two on this list are a scissor jaw trap that sets down inside the runway (pick 5) and a spring trap with curved jaws that you set by stepping on its pedal (pick 6). Either one works only in a run the mole still uses, so flatten a few short sections with your foot and set where the soil is pushed back up by the next day. If a trap catches nothing in two days, Penn State says the mole may have changed its habits, so move the trap to another active run.

Mole baits exist too. Nebraska Extension describes a gel squirted into the run and a worm shaped bait that contains bromethalin, says it has received numerous positive reports on the worm bait, and says more rigorous testing of these products is needed. A bait is a pesticide, and Nebraska's rule for it is that the label is the law: where it goes, how much to use, and what it says about children, pets and other animals all come from that product's label. Gas is a poor fit as well, because Penn State finds burrow fumigants largely ineffective, since moles can detect the gases.

Check your state's rules before you set any trap. Washington is one example: its Department of Fish and Wildlife says traditional body gripping mole traps are no longer legal there under Initiative 713, with no exceptions for emergencies.

How to keep voles off bulbs and bark

Voles are a habitat problem before they are a product problem, and their home range is small, usually a quarter acre or less. Take away the cover and most of the pressure goes with it. Mow into the fall, cut back tall grass and weedy edges next to beds, and pull mulch a full two feet back from trunks, which is Penn State's spec and far more than the few inches most people clear, since a mulch collar against bark is a vole tunnel with a roof. Our guides on mulching leaves and winterizing the garden cover the fall cleanup that does this work anyway.

For bark, use quarter inch hardware cloth. Penn State's spec is a cylinder 18 to 24 inches high around the trunk, buried four to six inches so voles cannot burrow under, sized loose enough for several years of growth.

For bulbs, the same mesh is the only thing that reliably works: dig the hole wider than you need, line the bottom and sides, backfill, and lay a piece over the top before the last few inches of soil. That is more digging than a trowel wants to do, and our D-handle garden spade opens a clean sided hole at bulb depth in one pass. Depth and spacing are in our guides to bulbs to plant in fall and planting tulip bulbs.

Two more levers. Plant what they will not eat: daffodils are toxic to rodents and get left alone, so interplanting them among tulips gives incidental protection, and a bed of daffodils is the low effort answer in a vole heavy yard. And trap, which extension guidance rates above repellents for voles. Set mouse sized snap traps perpendicular to a runway or at a burrow opening, bait with peanut butter and oatmeal or apple, and cover each with an inverted box so pets and birds stay out. Our guide to the best mouse traps compares the traps themselves and where to set them. Fall and late winter are when voles are easiest to catch.

When to treat, by season

• Early fall. Castor oil granules go down while the soil is warm and moist and moles feed near the surface. Cage bulbs now, because you are digging anyway.
• Late fall. Cut cover, pull mulch off trunks, and set trunk guards before the first snow.
• Winter. Nothing to apply. The damage is happening under the snow.
• Spring. Repair runways and ridges, re-treat as moles return to the surface, and trap if one survived the fall program.

Mole and vole repellents and traps, by job

Four granulars and two traps. Three are castor oil and differ mainly on price and area covered, one is for voles, and the traps are what you buy when the repellents have had their chance: one you set down inside the runway, one you set with your foot.

1. Bonide MoleMax Granules, 10 lb: castor oil granules for lawns and beds

Bonide MoleMax is a ready to use castor oil granule for moles and voles, sold in a 10 pound bag. Bonide sells it as safe for people and pets when used as directed, and it spreads by hand or by hopper. What to expect: it is a displacement product, so it moves moles along rather than removing them, and it is watered in after spreading. Check the coverage rate on the bag against your own square footage, because these products differ far more on area per bag than on chemistry.

When we checked on October 25, 2026, the 10 pound bag was out of stock on Amazon, so we do not link it for now.

2. Sweeney's S7002-2 Mole and Gopher Granules, 10 lb: for large lawns

Sweeney's S7002-2 is the same castor oil approach from a brand that has sold mole control for decades, in a 10 pound bag. The reason to look at it is the area the label says one bag treats, which is the number that matters once you are covering an acre rather than a city lot. Where it loses: on a small yard you are buying coverage you will not use, and Sweeney's sells poison bait worms under the same brand, a different product with a different risk profile that is not what is recommended here. Like every castor oil granule, it moves moles rather than removing them.

3. Plantskydd Deer, Rabbit and Vole Granular, 3 lb: vole repellent for bulbs and bark

Plantskydd granular is blood meal based, and the label positions it for voles along with deer and rabbits. Its stated mechanism is the right one for bulbs: it works by odor rather than taste, so the animal avoids the area instead of learning after the first bite, which is cold comfort once the tulip is hollow. Apply at planting, around the bed edge and over the backfilled hole, and reapply on the label's schedule. It comes in a 3 pound jug. What to expect: it has a noticeable odor for a day or two, and a hardware cloth cage is still the surer protection for a bulb that matters.

4. Victor Mole and Gopher Repellent, 10 lb: another castor oil granule

Victor Mole and Gopher Repellent is another 10 pound castor oil granule, with the same approach: same watering in, same expectations. Where it fits: its listing puts one 10 pound bag at up to 10,000 square feet, so check that figure, and the coverage on the other bags here, against your own square footage.

5. Victor Out O'Sight Mole Trap 0631A: scissor jaw trap for when repellents do not hold

The Victor Out O'Sight is a steel scissor jaw trap that sets down inside a deep main runway, out of sight of children and dogs. Extension guidance is consistent that trapping outperforms poison bait for moles, because an insect eater does not readily take a grain based bait. Use the 24 hour test to find an active run, then set there rather than in a surface ridge. Where it loses: it kills, which is a decision rather than a detail, placement takes a couple of attempts to learn, and a few states restrict body gripping traps, so check your rules first. The Tomcat mole trap, pick 6, is the alternative if you would rather set from above ground.

6. Tomcat Mole Trap: a mole trap you set with your foot

The Tomcat Mole Trap is a dual spring trap with curved jaws. You place the jaws in an active tunnel and step on the yellow foot pedal, which sets the trigger below the surface, so your hands stay away from the jaws while you set it. It is reusable, and this listing is one trap, so buy two if you have more than one active run. Find the run with the same 24 hour test as pick 5 and set it in a main runway, not a surface ridge.

Before you buy: check your state's rules on body gripping traps before you set it. Between the two traps, choose the setting method you are comfortable with; set either in an active run.

How to choose a mole or vole repellent

• Identify the animal first. Ridges and mounds are moles, and moles never eat bulbs. Narrow surface runways, quarter sized holes, chewed bulbs and gnawed bark are voles.
• Match the mechanism. Castor oil works through the mole's food supply, which is why it does little for a rodent. Odor repellents and exclusion are the vole tools.
• Buy on coverage, not brand. The castor oil granules are chemically similar, so compare treated square feet per dollar.
• Have a plan B ready. If two rounds of granules have not moved the mole, a trap is the next step, and nothing else works better.

Frequently asked questions

What is the best mole repellent?

A ready to use castor oil granule, spread over the whole area and watered in. Castor oil is the only repellent class extension sources credit at all, and they rate the effect minor. It works by making the soil and the earthworms in it unpalatable, so moles relocate. Expect it to push moles out of treated ground for a few weeks at a time, not to clear your property permanently.

Do castor oil mole repellents actually work?

Sometimes, and only as displacement. Castor oil is a federally listed minimum risk pesticide ingredient, so these products are sold without the efficacy review a conventional pesticide receives, and field results in the extension literature are mixed. Penn State Extension notes there are no chemical repellents registered for use on moles, and that electronic, magnetic and vibrating stakes have never been proven effective. Water granules in, re-treat the perimeter, and reapply after heavy rain.

How do I tell whether I have moles or voles?

Read the damage. Moles leave raised ridges snaking across the lawn and cone shaped mounds of loose soil, and they eat grubs and earthworms, never bulbs or roots. Voles leave surface runways an inch and a half to two inches wide with the grass clipped short, open holes about the size of a quarter with no mound, hollowed out bulbs, and bark gnawed off young trunks. Voles will also move into tunnels a mole dug, so you can have both at once.

What keeps voles from eating tulip bulbs?

Quarter inch hardware cloth is the only reliable answer. Line the planting hole on the bottom and sides, backfill, and lay a piece over the top before the final few inches of soil. Back that up by cutting the grassy cover next to the bed, pulling mulch two feet back from trunks, and interplanting daffodils, which are toxic to rodents and get left alone. Repellent granules applied at planting help but do not replace the mesh.

What is the best vole repellent?

A repellent is a backup, not the plan. Penn State Extension says little data is available on how well repellents deter vole damage, that they should not be the sole method of control, and that they must be reapplied after rain, heavy dew or new plant growth. Lead with the habitat: mow regularly, clear mulch 2 feet or more from the base of trees, and cage bulbs and young trunks in quarter inch hardware cloth. Then use an odor repellent at planting, and set mouse sized snap traps perpendicular to a runway, baited with peanut butter and oatmeal or apple slices, to remove the voles already there.

Do ultrasonic or vibrating mole stakes work?

There is no evidence that they do. Penn State Extension states that no electronic, magnetic or vibration device promoted for frightening or repelling moles has been proven effective, and moles habituate quickly to a steady noise in the soil. Spend the money on castor oil granules and, if those fail, on a trap.

How do I get rid of moles in my yard?

Work in order. Confirm the run is active by flattening a section of tunnel and checking it 24 hours later, spread castor oil granules over the whole area rather than along the ridges and water them in, then set a trap in an active main runway if two rounds of granules have not moved the mole. Skip the grub killer. Earthworms, not grubs, are the bulk of a mole's diet, so treating for grubs takes out part of the food supply and leaves the mole tunneling for the rest.

The bottom line

Diagnose before you buy. If you have ridges and mounds, spread castor oil granules over the whole area, water them in, and set a trap in an active runway if two rounds do not move the mole. If bulbs are disappearing and bark is chewed, that is a vole, and the order is cover removal, hardware cloth, an odor repellent, then snap traps. Doing the right one is worth more than spending more.
