Plague, Fleas and Rats: Is There Any Risk in NYC Today?
Plague is spread by fleas that live on rodents. In the United States it is rare and mostly found in western states. NYC residents should still avoid flea bites and rodent contact. This is general health information, not medical advice. If you feel unwell after rodent contact, talk to a doctor and mention the exposure.
Does plague still exist?
Yes. Plague is caused by the bacterium Yersinia pestis and still occurs in parts of the world. In the United States only a small number of cases are reported each year, mostly in rural western areas.
How do fleas spread plague?
Fleas bite infected rodents and then bite people. Handling infected animals can also spread it. Plague is treatable with antibiotics when found early.
Is plague a risk for New York City?
The risk is very low. The bigger everyday concerns in NYC are bites, allergies, contaminated food, leptospirosis and other rodent related illness. Rats do carry fleas, so flea control is still part of a good plan.
Signs of fleas in a home with rodents
Pets scratching, small jumping insects, bites on the ankles and black specks on bedding can mean fleas. Fleas often appear when rodents have been nesting nearby.
What to do
Remove the rodents first, because fleas will keep returning to the animals. Then treat the home for fleas. Our flea control service handles the second step, and our rodent services handle the first.
Protect your pets
Ask your vet about flea prevention. Keep pets away from dead rodents and from areas with droppings.
