An item-by-item personal protective equipment checklist for cleaning rodent-contaminated areas safely, aligned to current CDC guidance and refreshed during the 2026 MV Hondius outbreak.
At minimum, hantavirus rodent cleanup calls for a NIOSH-approved N95 respirator, nitrile or rubber gloves, and eye protection. For anything larger than a few droppings on a hard surface — a closed-up cabin, an attic, a shed, or a room with visible nesting material — add disposable coveralls, a stronger respirator (P100 or PAPR), and a clear plan for double-bagging the waste. Always ventilate, always wet-disinfect, and never improvise with a fabric mask or bandana.
The single most important piece of PPE. A NIOSH-approved N95 filters 95 percent of airborne particles down to 0.3 microns, which covers the size range of aerosolised hantavirus particles. Surgical masks and loose-fitting dust masks do not meet this standard. Always perform a user seal check: cup both hands gently over the mask, inhale sharply, and feel for any leak around the edges. Facial hair under the seal line breaks the seal and disqualifies the respirator. For heavy contamination, step up to a half-face elastomeric respirator with P100 filter cartridges, or a powered air-purifying respirator (PAPR) if you have one available.
Powder-free, medical-grade nitrile gloves are the standard. They resist punctures from chewed material and tolerate the disinfectant solutions used in cleanup. Heavier rubber gloves can be used for tasks that involve sustained contact with bleach solutions. Latex is acceptable if you have no sensitivity, but nitrile is preferred. Discard gloves into the contaminated waste bag at the end of the task; do not reuse them between rooms or surfaces.
The CDC explicitly recommends eye protection during rodent cleanup. Wraparound safety goggles or a full face shield prevent aerosolised particles and disinfectant splashes from reaching the eyes. Standard prescription glasses are not adequate — they do not seal at the sides. Anti-fog lenses are useful because fogging is the single most common reason people break their PPE protocol mid-task to wipe condensation off their goggles.
For any cleanup larger than a localised spot — anywhere with visible nesting material, droppings across a floor, a shed or attic, or a confirmed rodent infestation — a disposable Tyvek-style coverall keeps contaminated dust off your clothing and skin. The coverall is removed and bagged with the other contaminated waste at the end of the task. If a coverall is not available, dedicated clothing that can be laundered immediately on a hot cycle is an acceptable substitute.
The disinfectant is the active step in cleanup. The CDC-recommended solutions are a 1:10 dilution of household bleach (roughly 1.5 cups of bleach per gallon of water) or any EPA-registered disinfectant labelled effective against enveloped viruses. Spray the affected surfaces thoroughly enough to fully wet the droppings and nesting material, and let the solution sit for at least five minutes before any wiping. The five-minute contact time is the part most often skipped — and the part that does the actual virucidal work.
Use paper towels or disposable wipes — never a reusable cloth or sponge — to pick up wet-disinfected droppings and nesting material. Place the soiled towels directly into the contaminated waste bag. Do not shake or fold them.
The CDC double-bag protocol requires two bags. The inner bag is a standard kitchen-sized plastic bag that receives the contaminated material, PPE, and used wipes. The outer bag is a heavy-duty contractor-style bag that prevents tears during disposal. Wipe the outside of the inner bag with disinfectant, place it inside the outer bag, tie the outer bag, and dispose of it with regular household trash. Kitchen-only bags are not adequate as the outer layer; their thin gauge tears during handling.
After removing PPE in the correct order — gloves first, then coveralls, then eye protection, then respirator — wash hands and forearms thoroughly with soap and warm water for at least 20 seconds. If running water is not available, use a 70 percent ethanol or isopropyl hand sanitiser as an interim measure, but follow with soap and water as soon as practical.
PPE is only as protective as the order in which you put it on and take it off. The recommended sequence is: ventilate first; put on coveralls, then gloves, then eye protection, then respirator (with a user seal check) last. After cleanup, remove gloves first, then coveralls, then eye protection, then respirator. All contaminated PPE goes into the inner bag as you remove it. Wash your hands at the end. The whole sequence is sometimes called "donning and doffing" — the doffing phase is when most accidental self-contamination occurs in clinical and outbreak studies, so it is worth doing slowly.
Several items show up in informal advice that the CDC explicitly does not recommend. A cloth or bandana over the nose and mouth provides essentially no filtration of aerosolised hantavirus. A standard surgical mask, while better than nothing, does not seal and is not designed for inhalable hazards. A dust vacuum or shop-vac without HEPA filtration redistributes contaminated particles into the air and worsens exposure. Gl ue traps are also discouraged: stressed rodents trapped on adhesive boards continue to urinate, increasing the local aerosol load. Snap traps and tip traps are the CDC-recommended trap types.
The N95-and-gloves baseline is appropriate for a small, localised cleanup of a few droppings on a hard surface in a normally ventilated room. Step up to a half-face elastomeric P100 respirator and full coveralls for any of the following: a closed-up cabin, attic, shed or storage area that has not been opened in weeks or months; visible nesting material or a dead rodent; cleanup of more than a square metre of contamination; or cleanup in an endemic region such as the Four Corners area of the US Southwest or rural Patagonia. If you are working professionally with high-volume rodent contamination, a powered air-purifying respirator (PAPR) and a documented respiratory-protection programme are the appropriate next step.

For heavier contamination — a closed-up cabin, an attic, a shed or any space with visible nesting material — add disposable coveralls and consider an elastomeric respirator with P100 cartridges. Always ventilate the space for at least 30 minutes before entry and wet-disinfect rather than dry-sweep.
No. Loose-fitting dust masks and surgical masks do not form a tight seal and do not filter the fine aerosolised particles that carry hantavirus from disturbed rodent droppings. The CDC explicitly calls for a NIOSH-approved N95 or higher respirator with a proper user seal check. For heavy contamination, a half-face elastomeric respirator with P100 filters or a powered air-purifying respirator (PAPR) is preferable.
Powder-free, medical-grade nitrile gloves are the standard choice. Heavier rubber gloves can be used for tasks that involve handling disinfectant solutions for prolonged periods. Avoid latex if you have a known sensitivity. Discard gloves into the contaminated waste bag at the end of the task; do not reuse them between rooms or surfaces.
Coveralls are not strictly required for a small, localised cleanup with a few droppings on a hard surface, but they are recommended for any larger area, any attic, any cabin or storage area that has been closed up with rodent activity, and any task involving handling of nesting material or carcasses. A disposable Tyvek-style coverall keeps contaminated dust off your clothing and skin and is removed and bagged with the other contaminated waste at the end.
Place all contaminated PPE, droppings, nesting material and dead rodents into a sealed plastic bag. Wipe the outside of that bag with the same disinfectant you used for cleanup, and place the sealed inner bag inside a heavy-duty contractor-style outer bag. Tie the outer bag securely and dispose of it with regular household trash. Wash hands and forearms thoroughly with soap and water after removing PPE.
