Hantavirus Prevention Guide
Practical steps to protect yourself and your family from hantavirus infection.
Important Note
This guide provides general prevention information based on CDC and WHO recommendations. For specific situations or if you believe you have been exposed, consult a healthcare professional immediately.
Rodent-Proof Your Home
Seal entry points
Close gaps and holes larger than 6mm in walls, foundations, and around pipes using steel wool, caulk, or metal sheeting.
Install door sweeps
Ensure all exterior doors have tight-fitting sweeps and weatherstripping.
Secure screens
Repair damaged window and vent screens. Use metal mesh for crawl space vents.
Eliminate Food Sources
- Store food (including pet food) in thick plastic or metal containers with tight lids
- Clean up spilled food immediately and wash dishes promptly
- Use garbage cans with tight-fitting lids
- Keep outdoor areas clean - remove fallen fruit, bird seed, and debris
Safe Cleaning Procedures
Never sweep or vacuum rodent droppings, urine, or nesting materials. This can release virus particles into the air.
Ventilate the area
Open doors and windows for at least 30 minutes before cleaning. Leave during ventilation.
Wear protective gear
Use rubber or latex gloves. In heavily contaminated areas, wear an N95 respirator mask.
Spray with disinfectant
Thoroughly soak droppings and nesting materials with a bleach solution (1 part bleach to 10 parts water) or commercial disinfectant. Let sit for 5 minutes.
Wipe up with paper towels
Use damp paper towels to pick up materials. Double-bag waste in plastic bags and dispose in sealed outdoor trash.
Disinfect and wash
Mop floors and wipe surfaces with disinfectant. Remove gloves and wash hands thoroughly with soap and water.
Entering Closed Buildings
Cabins, sheds, or buildings that have been closed for a period may harbor rodents. Take these precautions:
- Open all doors and windows to air out the building for at least 30 minutes before entering
- Do not enter while airing out - wait outside
- When entering, wear an N95 mask if heavy rodent infestation is suspected
- Follow safe cleaning procedures before using the building
Handling Dead Rodents
- Always wear rubber or latex gloves
- Spray the rodent and surrounding area with disinfectant before handling
- Place in a double plastic bag, seal, and dispose in outdoor trash
- Wash hands thoroughly after removing gloves
