Hantavirus prevention

The single most effective protection against hantavirus is reducing contact with rodents and their excreta. Most documented exposures happen during cleanup of rodent-infested enclosed spaces — cabins, sheds, attics, barns, garages.

Keep rodents out

• Seal holes ¼ inch or larger in foundations, walls, and around utility pipes.
• Store food in rodent-proof containers; keep pet food sealed.
• Remove brush, woodpiles, and trash that provide harborage near homes.
• Use snap traps; check daily and dispose of carcasses safely.

Safe cleanup

• Ventilate the area for at least 30 minutes before entering.
• Do not sweep or vacuum dry droppings — this aerosolizes virus particles.
• Wear rubber or plastic gloves and an N95 respirator (minimum).
• Spray droppings, nests, and surfaces with a 1:10 bleach-water solution. Let soak 5 minutes.
• Wipe up with paper towels; double-bag waste; wash hands thoroughly.

Camping & cabins

• Inspect cabins before sleeping; air them out and clean before staying.
• Avoid sleeping on the ground in areas with rodent activity.
• Store food in sealed containers off the floor.
