You might spot chipmunks darting around your yard and think they’re just adorable little critters. Honestly, most people don’t worry about them at all. But have you ever wondered if they can actually carry diseases that might affect you or your family?
Chipmunks can carry several diseases that spread to humans, including plague, salmonella, and hantavirus.
Even though chipmunks usually steer clear of people and don’t act aggressive, they might bite if they feel cornered. Their bites can cause infections, and sometimes, though rarely, even tetanus.
It’s smart to stay cautious around chipmunks and avoid picking them up or handling them.
Knowing the risks lets you make better choices about your health and your property. If you want to keep your home and loved ones safer, understanding how chipmunks can affect you really helps.
How Chipmunks Transmit Diseases to Humans
Chipmunks, like other wild rodents, can carry diseases that you might pick up if you get too close to them or their nests. These diseases often spread through fleas or by touching chipmunks and their burrows.
Some places have higher risks because there are more rodents and parasites hanging around.
Common Diseases Spread by Chipmunks
Chipmunks can spread plague, salmonella, and hantavirus. Plague comes from bacteria and usually links back to fleas living on chipmunks and squirrels.
Salmonella might make you feel awful—think stomach pain and fever—after you touch chipmunk droppings or saliva. Hantavirus hits the lungs and spreads when you come into contact with urine, droppings, or saliva from infected chipmunks.
If a chipmunk bites you, you could get infections like tetanus or other bacterial issues. So, it’s best to leave chipmunks alone and avoid handling them.
Role of Fleas and Infected Rodents
Fleas play a huge role in spreading diseases like plague. These little pests live on chipmunks, squirrels, rats, and other wild rodents, picking up bacteria that can make people seriously ill.
If a flea bites you, it can pass those bacteria right into your bloodstream.
Chipmunks dig tunnels and burrows where fleas thrive. If you disturb these spots, you might run into infected fleas.
Places with a mix of rodents—like rats and rabbits—can raise your chances of running into fleas or getting sick from direct contact.
Areas with Higher Risk of Disease Transmission
Certain spots, like the Tahoe Basin and South Lake Tahoe in California, have wild rodents such as chipmunks and squirrels that carry disease-carrying fleas. These areas include El Dorado County and places near Taylor Creek Visitor Center.
If you visit these natural areas, don’t touch or feed wild rodents, and steer clear of their burrows.
Wearing protective clothing and keeping your distance can help lower your risk. Rodent populations in these places might carry plague bacteria, so being careful is important.
If you spend time outdoors where chipmunks live, especially in these regions, you should definitely stay alert.

Prevention and Safety Measures for Humans and Pets
To keep yourself and your pets safe from diseases chipmunks and other wild rodents carry, focus on personal safety, pet care, and keeping your home less inviting to rodents.
Taking a few practical steps can really cut down your risk of flea bites, infections, and unwanted critters moving in.
Personal Protection Practices
When you’re outside, especially in areas full of wild rodents, use insect repellent with DEET or permethrin. These help prevent flea and tick bites, which can carry nasty diseases.
Don’t touch or handle chipmunks and other wild rodents. If you have to clean up spots where rodents have nested or left droppings, wear gloves and a mask so you don’t breathe in dust that might carry viruses like hantavirus.
Seal up your home by caulking cracks and closing holes to keep rodents out. Also, clear away brush and piles of wood or debris near your house, since chipmunks love to hide or burrow there.
Pet Care and Flea Control
Your pets can pick up fleas from chipmunks and other wild rodents, and then those fleas can spread around your home.
Use flea control products your vet recommends, like flea collars or spot treatments, to protect your pets.
Check your pets for fleas or unusual scratching. Wash their bedding often to get rid of flea eggs and larvae.
Try not to let your pets roam in places where wild rodents are everywhere. That way, you lower the chances of fleas or diseases making their way to your pets.
Environmental Management Tips
If you want to keep chipmunks and squirrels away, start by removing easy food sources. Unsecured trash cans, bird feeders, and fallen fruit draw these little rodents right up to your home.
Trim your lawn often. Get rid of wood piles or rocks because rodents love to build burrows there.
Check for any openings around your foundation, windows, doors, or chimney. Go ahead and seal them up tight so critters can’t sneak inside.
Take a walk around your house now and then to look for signs of rodents—maybe chew marks or odd noises inside the walls. Catching problems early makes a huge difference and really helps protect your family from disease risks.
