Cleaning Mouse Droppings

Mouse droppings are ovoid and are approximately the size of a grain of rice. Larger droppings resemble and are commonly mistaken for cockroach or rat droppings. Certain mouse species transmit diseases and viruses through their droppings, urine and saliva.

Deer mice are the primary transmitters of Hantavirus, although other rodents may also be carriers. This virus is fatal and is found within the deer mouse's feces, urine and saliva. Hantavirus is transmitted to humans through airborne particles and symptoms are similar to those of the common flu.  However, individuals with this virus must seek medical attention immediately upon recognition; early identification can increase the patient's survival rate.

Extra care should be taken when cleaning mouse droppings from the home. Windows should be open and infested rooms should be aired out prior to cleaning efforts. Disinfectant should be sprayed through the room and across all surfaces. It is advisable to wear a tightly fitted mask, as well as protective gloves.

It is important not to sweep or vacuum mouse droppings, as these cleaning methods cause the release of more airborne virus particles. Dispose of any towels or cloths that come into contact with feces or the surfaces of an infested room. Gloves should be disposed of and it is suggested that the hands be washed several times after cleaning.
