Ever wondered if that twitchy squirrel in your yard might be rabid? Squirrels can technically get rabies, but honestly, it’s so rare that you probably don’t need to worry about catching it from them. That might take a little weight off your mind, but you might still be curious—why don’t small rodents spread rabies the way raccoons or bats do?
Let’s talk about what makes squirrels such unlikely carriers. I’ll cover what to look for if you spot a sick animal, and what you should do if you or your pet gets bitten.
Hopefully, this will help you stay calm and safe when wildlife pops up in your yard.
Why Can’t Squirrels Get Rabies?
Let’s get into why squirrel rabies is so rare. Their biology and behavior limit how the virus spreads, and the few documented cases we have really tell the story.
Rabies Transmission in Squirrels
Rabies spreads when infected saliva gets into a wound, usually from a bite. Squirrels hardly ever bite people, and their small size means they don’t usually get into serious fights with rabid animals.
When a rabid raccoon or bat attacks a squirrel, the squirrel usually dies from the injuries before the virus can travel from muscle to nerves and reach the salivary glands.
Rodents like squirrels count as incidental hosts. They might get rabies after a spillover event, but they don’t keep the virus going in their populations.
Public health teams rarely find positive rabies tests in squirrels compared to bats, raccoons, skunks, or foxes.
Biological Resistance and Behavior
Squirrels’ bodies and habits make rabies even less likely. Their small size gives the virus less room and time to move to the brain and saliva.
If a predator attacks, squirrels usually die quickly, so the virus doesn’t get a chance to spread.
Behavior matters too. Squirrels live in trees and are active during the day, while rabies carriers like bats are out at night.
Squirrels prefer to run away rather than fight, so they don’t get bitten often—and neither do people. All these factors explain why confirmed rabies cases in squirrels are almost unheard of.
Rare Documented Cases and Data
Sometimes, squirrels do test positive for rabies, but it’s extremely rare. State and national programs have only found a handful of cases over many years.
Usually, when a squirrel tests positive, investigators find out it got bitten by a known rabid animal or had some strange contact with a reservoir species.
If a squirrel bites or scratches you, treat it seriously. Wash the wound with soap and water, and get medical advice right away.
Health officials will look at your risk and decide if you need rabies shots. For more details, check out this explanation of why squirrels rarely have rabies.
Risks and Signs of Rabies in Squirrels
Squirrels almost never carry rabies, but it’s still smart to know what sick animals look like and what risk they might pose. Watch for odd movement, eating changes, or a sudden lack of fear around people.
Treat any bite or scratch as a possible exposure.
Signs of Rabies in Squirrels
Sudden changes in behavior are a red flag. An infected squirrel might lose its fear of people, act strangely tame, or come right up to you.
You might also see aggression, more biting, or a squirrel trying to bite objects or even itself.
Physical signs can show up too. Drooling or foaming at the mouth, trouble swallowing, and clumsy movement like stumbling or circling are all possible.
Lethargy, hind leg paralysis, or messy fur might show up late in the disease.
Other illnesses can look similar, though. You really can’t tell for sure if a squirrel has rabies just by looking at it.
If you find a sick or dead squirrel, don’t touch it. Call animal control so they can handle testing.
Risk of Rabies from Squirrels to Humans and Pets
Getting rabies from a squirrel is very unlikely. The risk jumps if you get bitten, scratched, or if saliva gets into a cut.
Always wash any wound right away with soap and water.
If a squirrel bites or scratches you, go see a doctor. They might recommend rabies shots depending on the situation and local rabies activity.
If your pet gets bitten, call your vet. Unvaccinated animals have a higher risk and may need treatment or quarantine.
Keep your pets vaccinated and avoid picking up wild squirrels—even the cute baby ones. These steps make a rare problem even less likely.
Do Squirrels Carry Rabies?
Squirrels really aren’t known for carrying rabies. In most places, raccoons, skunks, foxes, and bats end up being the main animals people worry about.
You hardly ever see rabies show up in squirrels when folks run tests. It’s just not that common.
A couple of things work in the squirrel’s favor here. Their small size means predators usually kill them quickly, so they don’t get much of a chance to spread the virus.
But let’s be honest—if a rabid animal bites a squirrel, it could still happen.
If you see a squirrel acting weird, don’t mess around. Call animal control and let them handle it.
