Marmots (also known as rock chucks) are indigenous to the western half of the United States. Cousins to the east coast woodchuck, Marmots are more likely to reside in elevated landscapes and have been found throughout most of the northwestern states. They readily occupy rock piles and will dig deep descending burrows around these protective objects.

Since marmots will readily claim a 4 to 5 acre territory, they’ve proven to be comfortable traveling great distances to find food. This is when they can become a nuisance. Marmots love most any garden grown vegetable and if given the chance, they’ll readily graze leading to rapid crop loss and damage.



Marmots start reproducing at 2 years of age. Colonies can support 10-20 individuals and though they’ll hibernate during cold winters, marmots can remain active during this time if temps are mild.

New colonies develop when teenage males (1-2 year olds that leave established colonies) move to a new territory and dig a new home. Once these bachelors have their new home, they’ll aggressively seek multiple females as mates. Male marmots will try to get at least 3-4 females to live with him and once they move in, breeding will start and continue all summer long.

Females will produce 3-5 pups per litter so as spring turns to summer, they’re food requirements can become quite substantial. This is when conflict with man can occur. Especially in dry arid regions where succulent plant food is limited. In such areas, marmots will travel as far as is needed to find a decent food supply for their young.



Marmots have natural predators like coyotes, fox, bobcat, cougar and timber wolf. Because they’re naturally afraid of these predators, one can use the urine of these animals as a barrier to keep marmots off your property. Just try to use a urine which is native to the area. In other words, if you have cougar or bobcat in your region, their urine will work. But if you don’t have timber wolves, it’s not likely marmots will be afraid of the scent.

Do this by applying 1-2 oz of urine every 10-15 feet along the side of your property boundary where marmots are most likely enter. Applications will remain active for 30-45 days and should be applied late winter through the spring and summer months since these are prime time for marmot migration.

Liquid GuardCapsule GuardsTo enable urine placements to last longer, make your placements using either CAPSULE GUARDS or LIQUID GUARDS. Either of these protective devices can be placed on the ground and when filled with urine, will protect it from the sun and rain. This protection will enable the urine to remain active for 60-90 days so that over time, either of these urine guards will pay for themselves many times over.

If you have a marmot feeding in your garden but not living on your land, the use of urine alone will probably not be strong enough to chase him away for good. This is because the lure of food is so strong most marmots will take the chance of passing through the regions where predator scent is located because they need to feed. In situations like this, the use of a live trap is the preferred method of control.

Live Trap 11x12x30Marmots are easy to trap and the LT111230RD is usually large enough to trap any marmot that might be foraging on your property. Place the trap where you see marmot trails, footprints or entry ways to your garden. Use a small amount of any plant or vegetable as lure (what the marmot has been targeting) and you should be able to trap them within a few days.

It features a “bottom entry” doorway which can be placed directly over their entrance/exit hole. This will effectively “force” them into the trap when they come out and makes catching them easy.

Woodchuck Bait Foumula I and IIFor either live trap, the fruit or vegetable they’re targeting in your garden will usually be the best bait to lure them in. But in cases where you’re not sure what they’re eating, go with some WOODCHUCK FOOD LURE. This plant based food lure works well on foraging marmots and a tablespoon or two placed in a small plastic tray will do the trick.

Once the problem marmots are removed from your property, use one of the predator urines listed above to keep new ones from foraging onto your property. Marmots can be a problem once they start nesting or feeding on your property so don’t let them get established. Live trapping is an easy way to remove unwanted marmots but if they’re nesting in your yard or garden, kill traps may be required to get rid of them for good. Once removed, use some animal urine to make sure they don’t come back.
