Don’t ‘Mouse Around With Spring Cleaning Interior Health Warning On Hantavirus

Interior Health is warning residents across British Columbia to take extra precautions during spring cleaning as concerns grow about possible exposure to hantavirus, a rare but potentially deadly disease carried by rodents. Health officials say people cleaning garages, sheds, cabins, basements, and storage areas could unknowingly expose themselves to dangerous airborne particles contaminated by mouse droppings or urine.

The warning comes as warmer spring weather encourages many people to open seasonal properties and clean enclosed spaces that may have been unused during winter. Interior Health says these locations can become ideal nesting areas for deer mice, the primary carriers of hantavirus in western Canada.

Health experts explained that hantavirus can spread when virus particles from rodent droppings, saliva, or urine become airborne and are inhaled by humans. Sweeping, vacuuming, or disturbing contaminated dust can increase the risk of exposure, especially in poorly ventilated spaces.

Interior Health urged residents not to “mouse around” with unsafe cleaning methods and advised people to avoid dry sweeping or vacuuming rodent waste. Instead, officials recommend ventilating enclosed spaces for at least 30 minutes before cleaning and using disinfectant sprays or bleach solutions to wet contaminated surfaces before wiping them carefully.

People are also encouraged to wear rubber gloves and, in some situations, properly fitted masks when cleaning heavily contaminated areas. Health officials stressed the importance of sealing food containers, blocking rodent entry points, and safely disposing of trash to reduce mouse activity around homes and cabins.

Hantavirus infections remain rare in Canada, but the illness can become extremely serious. Early symptoms often resemble the flu and may include fever, headaches, muscle aches, fatigue, nausea, and chills. In more severe cases, the infection can progress into Hantavirus Pulmonary Syndrome (HPS), a dangerous respiratory condition that causes difficulty breathing and fluid buildup in the lungs.

Medical experts say hantavirus has a high mortality rate once severe symptoms develop, making prevention and early awareness extremely important. Interior Health advised anyone experiencing flu-like symptoms after possible rodent exposure to seek medical attention immediately and inform healthcare providers about potential contact with mice or rodent-contaminated areas.

British Columbia has recorded multiple hantavirus cases over the years, particularly in Interior regions where deer mouse populations are more common. Rural properties, cabins, barns, and sheds are considered higher-risk locations for possible exposure.

The warning also follows increased public attention surrounding hantavirus after recent international reports involving cruise ship passengers and other possible exposure incidents. Although public health officials say general risk levels remain low, awareness about rodent safety and proper cleaning practices has increased significantly in recent weeks.

Environmental experts say spring is often an important period for rodent prevention because mice become more active as temperatures rise. Residents are encouraged to inspect buildings for small openings, cracks, and gaps where rodents may enter.

Interior Health emphasized that simple preventive measures can greatly reduce exposure risk. Officials said most hantavirus infections can be avoided through safe cleaning practices, proper ventilation, and minimizing direct contact with rodent waste.

Health authorities continue monitoring hantavirus activity across British Columbia and are encouraging residents to remain cautious while cleaning seasonal properties during the spring months.
