When you think about squirrels, you probably just see them as harmless little creatures hanging out at the park. As far as anyone can tell, no one has ever actually died directly from a squirrel attack — the real risks sneak in through accidents they trigger or the rare diseases they might carry.
Curious about how squirrels might put you in harm’s way, what to watch out for, and how to keep yourself safe? Let’s get into it.
Has Anyone Ever Been Killed by a Squirrel?
Honestly, it’s almost unheard of for a squirrel to kill a person outright. Most of the trouble squirrels cause comes from their bites, infections, or weird accidents.
Documented Squirrel Attacks on Humans
There have been a handful of cases where squirrels bit or scratched people. Usually, these happen when someone tries to feed, grab, or corner a squirrel. Sometimes, wild squirrels act off because they’re sick — rabies or other illnesses can make them more aggressive.
Back in 1921, a squirrel in New York reportedly attacked some kids before someone shot it. That kind of thing tends to freak people out, understandably. These days, most reports are pretty minor. If a squirrel bites you, clean the wound, see a doctor, and let local health folks know so they can check for disease.
Severe Squirrel-Related Injuries
Squirrel bites aren’t something to shrug off. They can get infected or sometimes need stitches. Bacterial infections from a bite or scratch can get nasty, especially if your immune system isn’t great. Tetanus and wound infections are more common than rabies, honestly.
People in places like San Rafael and Lucas Valley might see squirrels up close more often. If a bite breaks your skin, get checked out by a doctor. Sometimes you’ll need antibiotics, a tetanus shot, or maybe even rabies treatment, depending on what the squirrel was doing and what the local health department says.
Squirrel-Related Fatal Accidents
Squirrels have caused some tragic accidents, but not in the way you might expect. Drivers have swerved to avoid a squirrel and crashed, sometimes fatally. Hikers, distracted by a squirrel darting across a steep trail, can fall and get seriously hurt.
Squirrels also chew on electrical wires, and that’s led to house fires. Rare, but it happens. Some people haven’t been able to escape those fires. If you live near places like Mount Lassen or on the wildland-urban edge, you might see more squirrel trouble with power lines or homes. Checking your place regularly helps. And on the road, it’s safer to stay in control than to swerve for a squirrel.
Health Threats and Disease Transmission from Squirrels
Squirrels can carry bacteria, parasites, and ticks that mess with people and pets. It’s good to know which illnesses actually matter, what signs to look for, and who to call if you need help keeping squirrels at bay.
Serious Diseases Carried by Squirrels
Squirrels can host some illnesses you’d rather avoid. Leptospirosis and salmonellosis are both bacterial and spread through their urine or feces. Squirrels also bring fleas and ticks into the mix, and those can pass diseases to you or your pets. Ticks on squirrels sometimes carry Lyme disease, which spreads if the tick bites you or your furry friend.
Pets get exposed more if they chase or munch on squirrels. Keep your pets on whatever flea and tick stuff your vet recommends, and don’t feed or handle wild squirrels. If you need advice or help with wildlife, reach out to Marin Humane or a licensed animal control service nearby. And if you see a dead or sick squirrel, don’t touch it — let animal control know.
Symptoms and Risks of Tularemia and Lyme Disease
Tularemia and Lyme disease show up differently, so you’ll want to know what to watch for. Tularemia can hit hard with sudden fever, swollen lymph nodes, and a skin ulcer after a bite or handling an infected animal. If you get a high fever after being around wild rodents, tell your doctor so they can test and treat you fast.
Lyme disease often starts with a circular rash, fever, tiredness, and joint pain a few days or weeks after a tick bite. Catching it early with antibiotics really helps. After spending time where ticks hang out, check yourself and your pets. If you find a tick, pull it out with tweezers and save it in a bag in case your doctor or vet wants to see it.
Role of Local Agencies in Squirrel Attack Prevention
Local agencies step in to help you avoid risky encounters and deal with wildlife safely. Marin Humane actually gives advice on humane deterrence, pet safety, and when it’s time to call wildlife professionals for removal.
Local public health departments watch for trends in tick-borne diseases. Sometimes, they’ll offer testing or send out public alerts if there’s a tularemia or Lyme outbreak nearby.
If you spot an aggressive, sick, or dead squirrel, go ahead and report it to animal control. They’ll check for disease or rabies risk.
For problems with your property—like attics, chimneys, or yards—hire licensed wildlife removers. They follow local rules and keep you and your pets out of harm’s way.
It’s smart to follow agency advice about sealing entry points and getting rid of food attractants. Use only approved trap-and-release or exclusion methods.
