The real health risks of a rodent infestation
Yes. Rats and mice are a recognized health hazard. They can spread disease through their droppings, urine, and bites, contaminate food, and their waste can affect the air inside a home.
Rodents travel through filthy spaces and then across counters and into food, which can spread germs. Their droppings and urine can carry disease, and disturbing dried droppings can send particles into the air — which is why health agencies recommend cleaning them carefully rather than sweeping or vacuuming dry. Any food rodents have gotten into should be thrown out.
Because of these real risks, a serious infestation is treated as a health and habitability problem, not just a nuisance, and it is something the landlord is expected to address. This is general information, not medical advice — see a doctor about any health concerns. If a rodent problem is affecting your household and your landlord will not act, a free review can explain your options.
