Ever spotted a chipmunk darting through your backyard and wondered if these little guys might bring any health risks? Chipmunks can carry some diseases, but honestly, they rarely infect people directly. It’s usually the fleas and ticks hitching a ride on them that spread trouble.
It helps to know which diseases chipmunks can carry so you can enjoy the outdoors with a bit more peace of mind. Some illnesses, like plague or Lyme disease, are rare but can get serious fast.
When you understand how these diseases spread, you can protect yourself without worrying every time you see a chipmunk.
Diseases Carried by Chipmunks and Related Rodents
Chipmunks and other rodents sometimes carry diseases that can affect people and pets. Some of these illnesses spread through bites or contact with droppings, while others come from fleas or ticks that use chipmunks as hosts.
It’s worth knowing about these risks so you can take steps to keep your family safe.
Understanding Plague in Chipmunks
Plague is a pretty serious bacterial disease that people have linked to chipmunks and squirrels. Fleas that infest these animals often carry the bacteria.
When a flea bites an infected chipmunk, it can pick up the bacteria and then bite a human or pet, spreading the illness. That’s how it usually happens.
In places like El Dorado County and South Lake Tahoe, California, health officials keep a close eye out for plague cases. If you live in or visit these areas, you should know the symptoms—fever, swollen lymph nodes, chills.
If you suspect exposure, getting antibiotics quickly is key.
Transmission Pathways to Humans and Pets
Diseases can reach humans from chipmunks in several ways. Direct contact, like a bite or scratch, poses one risk.
However, you can also get sick from touching or even breathing in dust contaminated by chipmunk urine or droppings. That’s not something most folks think about.
Fleas and ticks on chipmunks can also bite you or your pets and spread illnesses like Lyme disease. Keeping garbage sealed and pet food in airtight containers makes your yard less attractive to chipmunks and lowers your risk.
Other Diseases Linked to Rodents
Chipmunks can also carry hantavirus, leptospirosis, and salmonella. Hantavirus spreads when you breathe in dust from contaminated droppings or urine, and it can cause some nasty lung problems.
Leptospirosis passes through contact with infected urine and can mess with your kidneys and liver. Salmonella can show up after handling chipmunks or their droppings, leading to stomach trouble.
Rabies in chipmunks is rare, but it’s not impossible. It’s smart to avoid close contact with wild rodents and keep an eye on your kids and pets around them.
Geographic Hotspots and Public Health Monitoring
Some regions, like parts of California—think South Lake Tahoe and El Dorado County—report more chipmunk-borne diseases like plague. Local public health officers keep tabs on these areas to warn people and help manage risks.
Health teams track disease cases and might suggest things like wearing gloves when cleaning up chipmunk habitats. They also recommend controlling chipmunk populations around homes in safe ways.
If you know your area’s risks, you can make better choices to avoid getting sick.

Prevention and Safety Precautions Around Chipmunks
Keeping your family safe starts with understanding how chipmunks can impact pets, your yard, and your health. Try to avoid contact with rodent burrows, use insect repellent when needed, and be cautious outdoors.
These steps really can help lower your risk.
Protecting Pets and Avoiding Rodent Burrows
Chipmunks carry ticks, fleas, and mites that may end up on your pets. Keep pets away from areas with holes or burrows, since those spots shelter parasites.
It’s a good idea to check your pets regularly for ticks or any weird bites.
If you find burrows near your house, don’t disturb them. Those tunnels can cause damage and make it easier for pests to get close to your home.
Seal up gaps and clear out dense plants to give chipmunks fewer places to hide.
Keep pet food inside or tightly sealed. Leaving food outdoors brings chipmunks (and their pests) closer to your pets.
Cleaning up your yard often helps, too.
Proper Use of Insect Repellent
Because chipmunks can carry ticks that spread disease, using insect repellent on your skin and clothes is a smart move. Go for repellents with DEET or picaridin—they work well.
Put repellent on exposed skin and outer clothing before heading outside, especially if you’ll be in grassy or wooded places. Avoid putting it on your hands, eyes, or mouth.
For pets, ask your vet about safe tick prevention. Don’t use human repellent on animals.
When you come inside, wash off the repellent to avoid skin irritation. Using it right really lowers your chances of picking up diseases from chipmunk-carrying insects.
Responsible Human Behavior Outdoors
Don’t try to handle chipmunks or catch them, even if they look tame or hurt. If you trap a chipmunk, it’ll probably bite—and that’s just asking for an infection.
Stay away from rodent burrows and nests. If you spot droppings, put on gloves and use a bleach solution to clean up, since it’s the safest way to kill germs.
When you’re out hiking or gardening, it’s smart to wear long sleeves and pants. Stick to clear trails, and watch your step so you don’t bother chipmunk homes.
If a chipmunk bites you, wash the area right away with soap and water. If the bite turns red or swollen, go talk to a doctor.
