What Kills Hantavirus? Bleach, UV Light, Heat & Effective Disinfectants

What works in the environment

1. Household bleach (1:10 dilution)

   The CDC recommends a 1:10 solution of household bleach (about 5–6% sodium hypochlorite) in water. Wet contaminated surfaces and droppings thoroughly and allow at least 5 minutes of contact time before wiping. Mix fresh solution; diluted bleach loses strength over time.

2. EPA-registered disinfectants

   Some commercial disinfectants labeled effective against hantavirus can be used per manufacturer instructions. Bleach remains the most widely cited standard for rodent-area cleanup.

3. Heat

   Washing fabrics in hot water (about 130°F / 54°C or higher) and high-heat drying helps inactivate virus on laundry. Steam cleaning can be used for items that cannot be bleached, following product guidance.

4. Sunlight (UV)

   Outdoor UV exposure reduces viability on surfaces over time, but indoor cracks, upholstery, and shaded areas may not receive enough UV. Do not rely on sunlight alone for indoor cleanup — use wet disinfection.

5. Alcohol-based hand sanitizer

   Enveloped viruses are generally susceptible to alcohol. Sanitizer (about 60%+ alcohol) is useful for hand hygiene in the field but does not replace respiratory protection and wet cleanup of rodent material.

6. What does not work safely

   Dry sweeping, dry dusting, and ordinary vacuuming without HEPA containment can aerosolize virus from rodent waste. That increases inhalation risk and is what the CDC protocol is designed to prevent.
