Identifying Marmot Droppings

Like many rodents, marmots leave droppings that are small, dark in color, elongated, and pointed on the ends. However, unlike similar animals, marmots rarely leave their feces in yards. Instead, they build latrine chambers in their burrows. Pests like squirrels, skunks, and prairie dogs tend to be the culprit in mistaken feces identification. If homeowners have indeed found marmot droppings, they will usually be located within a couple feet of a burrow entrance as the rodents use a mixture of earth and feces to seal the entrance before hibernation.

Disease Risks

Although they look relatively small and innocuous, marmot feces can be quite hazardous because they are the main way that marmot diseases, such as leptospirosis and salmonellosis, are transmitted to humans. This waste can also carry spores and bacteria, which become airborne when disturbed. Additionally, areas where the pests spend enough time to defecate may be infested with parasites from their fur. Ticks and fleas left by marmots can infect humans with Lyme disease and Rocky Mountain spotted fever.


Fencing is the best means of preventing marmots from entering yards. Fences should extend at least a foot or two below the ground because of the creatures’ burrowing skills. Additionally, there are some repellants known to keep marmots away, but these can be harmful to vegetation. Due to the ease with which disease can spread when handling marmot droppings, it is recommended that homeowners contact the professionals at Trutech to take care of any problems with these pests.
