Many people will make the mistake of vacuuming mouse droppings, we do not recommend this, as it is a health and safety concern considering the diseases that are carried through mouse droppings. Instead, we suggest that you first put on gloves and then spray a sanitizer on the droppings, sweep them up with old clothing or rags, and sanitize again when done.
Keep in mind that where mice leave feces, they will also leave urine, and these can both contain the hantavirus.
