How to clean up old rat droppings safely
Old rodent droppings carry dangerous pathogens like hantavirus that become airborne if swept or vacuumed, making people terrified of exposure or falling ill during cleanup. This fear stops them from tackling infestations in neglected spaces, leading them to leave hazardous waste behind or abandon the cleaning process altogether.
