Hantavirus Threat Resurfaces in 2026: Here’s What You Should Know from the Entomologists at the National Pest Management Association

FAIRFAX, VA--(BUSINESS WIRE)--Feb 3, 2026--

California has reported the country’s first positive hantavirus rodent detection of 2026, a stark reminder that this disease remains an active threat. The disease gained renewed attention last year following the tragic death of Betsy Arakawa, wife of Gene Hackman, from hantavirus pulmonary syndrome (HPS).

“Rodent-borne diseases didn't disappear after last year's tragedy," said Dr. Jim Fredericks, Board Certified Entomologist and Senior Vice President of Public Affairs at the National Pest Management Association ( NPMA ). "The danger is real, especially during the colder months as rodents push their way indoors, but early prevention and working with a pest control professional are key to protecting your health.”

Yet most Americans remain unaware of rodent health risks. In a survey conducted online by The Harris Poll on behalf of NPMA, only 28% of Americans are aware that rodents can carry diseases.

While deer mice spread hantavirus, other rodents can transmit more than 35 diseases to humans, including leptospirosis (liver and kidney damage), salmonellosis (food poisoning), hemorrhagic fever with renal syndrome (kidney failure), and rat-bite fever. Rodents also trigger allergies and asthma, contaminate food, and cause structural damage.

To protect your home and health, NPMA encourages you to:

• Never sweep or vacuum rodent droppings. This can release deadly particles into the air. Soak with bleach-based disinfectant, then wipe or mop the area.
• Seal cracks and holes. Rodents can squeeze through openings as small as a dime.
• Store food in airtight containers.
• Remove clutter where mice and other rodents build nests.

If you suspect rodents in your home, contact a qualified pest control professional immediately. They know how to safely remove and prevent them from returning. To learn more, visit PestWorld.org.
