Moles are mammals, so they can technically become infected with the rabies virus, but documented cases are extraordinarily rare. No mole species serves as a reservoir for rabies, and the biology of moles makes them among the least likely mammals to encounter, contract, or transmit the disease. If your concern is a specific mole bite or a mole you found acting strangely, the practical risk is near zero, though a few situations still warrant medical attention.
Why Moles Are Such Unlikely Rabies Carriers
Rabies circulates in nature through reservoir species, animals whose populations sustain ongoing transmission of the virus. In North America, those reservoirs are raccoons, skunks, foxes, and several species of bats. In much of the developing world, domestic dogs fill that role. Moles do not appear on any list of reservoir species anywhere in the world, and there is a straightforward reason: their lifestyle almost completely isolates them from the animals that carry the virus.
Moles spend the vast majority of their lives underground in self-dug tunnel systems. They are solitary, territorial, and insectivorous, feeding on earthworms, grubs, and beetles rather than foraging at the surface where encounters with raccoons, skunks, or bats would occur. A mole would need to be bitten by a rabid animal to become infected, and the opportunities for that kind of contact are minimal when you live in a burrow and rarely surface. Even among small mammals that do spend time above ground, rabies is uncommon. Moles, which barely surface at all, sit at the extreme low end of that already low-risk spectrum.
Their small body size also matters. When a tiny mammal is bitten by a larger rabid predator, the bite is usually fatal from the physical trauma alone, meaning the mole dies before it could develop a rabies infection and pass it along. This dynamic applies broadly to very small mammals and partly explains why rabies circulates almost exclusively in medium-sized and larger species.
What Surveillance Data Actually Shows
Moles are classified in the order Eulipotyphla, not Rodentia, so they are not technically rodents. But the closest available surveillance data comes from studies tracking rabies in rodents and lagomorphs (rabbits and hares), which are small mammals occupying a similarly peripheral position in the rabies landscape. This data is useful as a reference point, because if rabies is rare even in above-ground rodents, it is almost certainly rarer in subterranean moles.
A study analyzing U.S. rabies surveillance from 1995 to 2010 found that rabies was seldom reported in rodents and lagomorphs, and that bites from these animals rarely led to the need for post-exposure treatment in humans.1PubMed Central. Rabies in rodents and lagomorphs in the United States, 1995–2010 A follow-up analysis covering 2011 to 2020 reported 401 total rabies cases across all rodents and lagomorphs in the entire United States and Puerto Rico over that decade. More than 90% of those cases were in groundhogs, and the overall percent positivity in any given year stayed below 2.5%.2PubMed Central. RABIES IN RODENTS AND LAGOMORPHS IN THE USA, 2011-20 Groundhogs are a notable outlier among small mammals because they are large, surface-dwelling, and commonly live in areas with high raccoon density, which exposes them to rabid bites far more often than other rodents.
Moles were not individually tracked in these datasets, which itself tells you something about how rare rabies is in them. When researchers and public health agencies design surveillance systems, they focus resources on species that actually contribute to transmission. Moles have never risen to that threshold.
The Groundhog Exception and Why It Does Not Apply to Moles
The fact that groundhogs accounted for over 90% of rabies cases among rodents and lagomorphs might seem alarming at first glance, but it actually reinforces how safe moles are. Groundhogs are hefty animals that live in open burrows at the edges of fields and yards, right in the territory of raccoons and skunks. Their burrows have wide entrances, and they spend substantial time above ground feeding on vegetation. When raccoon rabies surges in a region, groundhog rabies cases tend to follow the same geographic pattern.2PubMed Central. RABIES IN RODENTS AND LAGOMORPHS IN THE USA, 2011-20
Moles have none of these characteristics. Their tunnels are narrow and largely sealed. They rarely come to the surface, and when they do, it is briefly and usually at night. They do not share den sites with medium-sized carnivores. The ecological overlap between moles and rabies reservoir species is close to nonexistent, which is why moles do not show up in rabies statistics the way groundhogs do.
What to Do If a Mole Bites You
Mole bites happen occasionally. Gardeners sometimes encounter moles while digging, and a mole that feels trapped will bite in self-defense. The bite is usually small but can break the skin, and the natural question is whether rabies is a concern.
The honest answer is that the rabies risk from a mole bite is about as close to zero as any mammal bite can be. However, public health protocols still apply in certain circumstances. Because moles cannot realistically be captured and held for a 10-day observation period the way a dog or cat can, and because they are too small to easily test, health authorities sometimes have to make conservative decisions. In a study from Bosnia and Herzegovina that cataloged animal bites reported to health authorities, one case involved a mole bite. Because the mole could not be placed under veterinary observation, post-exposure prophylaxis was administered as a precautionary measure.3PubMed Central.

That does not mean every mole bite requires rabies treatment. The decision depends on context. In the United States, the CDC and state health departments recommend evaluating rodent and similar small mammal bites on a case-by-case basis, considering whether the animal’s behavior was unusual, whether the bite was provoked, and how common rabies is in the local wildlife population.1PubMed Central. Rabies in rodents and lagomorphs in the United States, 1995–2010 A mole that bites because you accidentally dug it up is exhibiting normal defensive behavior, which is very different from an animal that approaches and bites without provocation.
Practical steps if you are bitten by a mole:
- Wash immediately: Rinse the wound thoroughly with soap and running water for at least five minutes. This is the single most effective first-response measure for any animal bite, regardless of rabies risk.
- Contact your doctor or local health department: They can assess whether your specific situation warrants further action. In most cases involving a provoked mole bite in a low-rabies area, they will not recommend post-exposure treatment.
- Watch for infection: Bacterial infection from the bite wound itself is a far more realistic concern than rabies. Signs include redness, swelling, warmth, or pus at the wound site over the following days.
Animals That Actually Pose a Rabies Threat
If you are worried about rabies from wildlife encounters, the animals worth being cautious around are well-established. In the United States, nearly all animal rabies cases come from five groups: raccoons, skunks, bats, foxes, and coyotes. Bats deserve special attention because their bites are so small that a person can be bitten while sleeping and not realize it, which is why the CDC recommends considering post-exposure treatment if you wake up to find a bat in your room.
Globally, domestic dogs are responsible for the overwhelming majority of human rabies deaths, mostly in parts of Asia and Africa where canine vaccination programs have not yet reached full coverage. In Africa, multiple lyssaviruses (the broader family that includes rabies virus) circulate among carnivores and bats, adding complexity to the picture.4Springer. Emergence of lyssaviruses in the Old World: the case of Africa But moles are not implicated as carriers of any lyssavirus species anywhere in the world.
The key principle is that rabies maintains itself in specific host populations. The virus needs a cycle of biting and being bitten to persist, and that cycle depends on animals that have frequent aggressive contact with each other. Solitary, subterranean insectivores like moles simply do not participate in that cycle.
How Rabies Transmission Works and Why Mole Biology Disrupts It
Rabies virus travels through saliva. An infected animal sheds virus in its saliva during the final stages of the disease, and transmission requires that saliva to enter a wound, usually through a bite. The virus then travels along peripheral nerves toward the brain, a journey that can take weeks to months depending on how far the bite site is from the head.
Research on bats has shown that the route of inoculation and the animal’s physiology can dramatically affect whether virus ends up in saliva at all. In a study on silver-haired bats, only bats that were inoculated in certain ways or that entered hibernation actually shed virus in their saliva. Bats inoculated by other routes and kept at normal temperatures did not shed virus orally, even when they developed rabies.5PLOS ONE. Overwintering of Rabies Virus in Silver Haired Bats (Lasionycteris noctivagans) This illustrates that infection alone does not guarantee transmission. The virus has to reach the salivary glands, and that process is not automatic.
For moles, even the hypothetical scenario is stacked against transmission. A mole would first need to be bitten by a rabid animal and survive long enough for the virus to reach its brain and salivary glands. Given that most encounters between moles and rabid predators would be fatal to the mole from trauma, and that moles have minimal contact with humans even if they did survive, the chain of events required for a mole-to-human rabies transmission is vanishingly improbable.
Why Moles Are Rarely Tested for Rabies
Part of the reason there is so little data specifically about moles and rabies is that public health labs almost never test them. Rabies testing requires the animal’s brain tissue, which means the animal must be dead and available for submission. The standard test, the fluorescent antibody test, examines brain tissue for the presence of rabies virus antigens, and it is highly sensitive when performed on properly handled specimens.6ScienceDirect.

But labs have limited capacity, and health departments prioritize testing animals that are most likely to be rabid and most likely to have exposed someone. A bat found in a bedroom gets tested. A stray dog that bites someone gets tested. A mole in someone’s garden does not, because the pre-test probability of a positive result is essentially zero, and the resources are better spent elsewhere. This creates a data gap: we cannot say with absolute certainty that no mole has ever been rabid, because so few have been tested. But the absence of testing reflects the professional consensus that moles are not a meaningful part of the rabies picture.
Diseases Moles Can Actually Carry
While rabies is not a realistic concern with moles, they are not completely harmless from a disease perspective. Moles can carry external parasites, especially ticks and fleas, which can transmit diseases like Lyme disease or tularemia to humans indirectly. The mole itself is not infecting you in these cases; the tick that hitched a ride on the mole and then dropped off in your yard is the problem.
Moles can also carry various bacteria in their mouths, as all mammals do. A bite wound that breaks the skin can introduce bacteria and cause a localized infection. This is the most common medical issue following a mole bite, and it is easily treated with wound care and, if needed, antibiotics. Some moles also harbor intestinal parasites that can contaminate soil, though direct transmission to humans through this route is uncommon.
Leptospirosis is occasionally mentioned in connection with moles and other burrowing mammals. The bacteria that cause it, Leptospira species, can be shed in urine and survive in moist soil. However, human leptospirosis cases are overwhelmingly linked to contact with water or soil contaminated by rats, dogs, or livestock, not moles.
When Strange Mole Behavior Actually Warrants Concern
People sometimes see a mole above ground in daylight and assume something is wrong. Moles do surface occasionally for normal reasons: dispersing juveniles looking for new territory, males searching for mates during breeding season, or any mole displaced by flooding or heavy soil disturbance. A mole on the surface is not automatically a sick mole.
That said, any wild mammal that appears disoriented, unusually aggressive, or unafraid of humans deserves caution, not because moles specifically are a rabies risk, but because abnormal behavior in any mammal is worth noting and avoiding. Do not handle the animal. If it is behaving in a way that concerns you, contact your local animal control or wildlife agency. They can assess the situation and decide whether testing is warranted.
The broader point is one of proportionality. Rabies is a terrifying disease with a near-100% fatality rate once symptoms appear, so it is natural to worry about it after any animal encounter. But the risk calculation is not the same for all mammals. A bat bite, a raccoon bite, and a mole bite are in completely different categories. Health authorities have developed detailed guidelines precisely so that people can get appropriate treatment when they need it without undergoing unnecessary medical procedures when they do not. For moles, the vast majority of encounters fall firmly in the “no treatment needed” category, with the rare exception of unprovoked bites by animals behaving abnormally in areas where rabies is highly active in wildlife.
