Rodent droppings are treated as a contamination hazard because they can carry germs. In homes, the key risk is dust. In larger or older infestations, cleanup follows biohazard-style methods with protective gear and sealed disposal.
Hard surfaces and items in sealed plastic containers can usually be cleaned and kept. Insulation, cardboard and fabric soiled with droppings or urine are generally discarded. The crew sorts items with you before anything is thrown out.
Mouse droppings and urine can carry germs, including hantavirus in some wild rodents. They are not poisonous like a chemical, but breathing in dust or touching them without protection can make people sick.
Disinfectants can inactivate the virus, which is why droppings are soaked before they are wiped up. The method matters as much as the product. Follow label directions and never mix cleaners.
A rodent cleanup service or biohazard cleanup team usually does this work. Attics and crawl spaces are tight, dusty and hard to reach, and soiled insulation often has to be removed. Pest control deals with the animals themselves.
Do not sweep. A cleanup team can plan the safe way to remove them.
