Health Department - Environmental
Cheyenne-Laramie County Health Department recommends residents
use caution and avoid Hantavirus when opening cabins, sheds
or garages that have been closed all winter.
In Wyoming, a small percentage of the deer mouse population carries the Hanta-virus,
which is Hantavirus Pulmonary Syndrome (HPS) and a potentially life threatening
disease caused by breathing dust contaminated by the virus.
winter rodents seek enclosed areas leaving behind infected
feces, urine, nesting material, saliva or carcasses that
then dries out and becomes dust and dirt in these structures.
precautions need to be taken when cleaning these structures.
Always wear rubber or plastic gloves and a mask while cleaning.
Spray dust and dirt with a bleach solution of 1 cup of bleach
per gallon of water to both settle the dust and kill any
virus present. Soak nests, carcasses, droppings or areas
of urine stains with a disinfectant solution. Use disposable
towels, rags or a wet mop to wipe up the dust and dirt rather
than sweeping or vacuuming. Dispose of towels and rags in
a covered garbage container. When finished, wash gloved hands
with soap and water or spray with disinfectant solution.
Once gloves are removed, wash hands with soap and water.
Use of a pesticide is recommended when dealing with carcasses
because of the danger of plague carrying fleas that rodents
are often infested with. Place disinfectant, soaked carcass
in a sealed plastic bag, place bag inside another sealed
bag and place in a covered garbage can for proper disposal.
