When people hear the word “plague,” most think of medieval times. But here in California, plague is still found in wildlife, carried quietly by rodents and the fleas that live on them. While human cases are extremely rare, a South Lake Tahoe resident tested positive in August 2025 after likely being bitten by an infected flea while camping.
Northern California communities, including Chico, Redding, and the foothills , are part of plague’s natural range. That doesn’t mean you need to panic. It means staying informed and taking practical steps to keep fleas away from your family, pets, and property.
Fleas reproduce quickly, cause painful bites, and thrive both indoors and out. Beyond the discomfort, they also pose health risks:
That’s why professional treatment matters. Flea problems don’t just go away on their own.
If your pets spend time outdoors, wash their bedding weekly in hot water and vacuum floors regularly. This helps disrupt the flea life cycle and makes treatments even more effective.
One person tested positive for plague after camping, reminding us that plague is still present in our region.
Rodents in Northern California continue to test positive for plague each year, especially ground squirrels and chipmunks in the foothills.
While no recent human cases have been reported locally, Butte County and surrounding regions are considered part of California’s plague range.
Ground squirrels, chipmunks, and mice carry plague bacteria. Their fleas become infected and spread it to new hosts.
Dogs and cats can bring fleas indoors after roaming or sniffing around rodent areas.
Hungry fleas may bite people, especially around ankles and legs, transferring bacteria.
Fleas don’t just appear out of nowhere – they usually come from the rodents living around your property. Ground squirrels, mice, and rats can all carry fleas that spread disease. By addressing the rodent problem first, you cut off the flea infestation at its source.

Yes. Pets that roam outdoors may pick up fleas from wild rodents. Using vet-approved flea prevention and scheduling professional pest control helps protect your household.
Symptoms usually include fever, chills, weakness, and swollen lymph nodes within 2–6 days of a flea bite. Seek medical care immediately if you experience these after possible exposure.
Shelby’s uses treatments that target fleas at every life stage – eggs, larvae, and adults – making them more effective than DIY sprays or store-bought products.
