Sometimes, but not always. Many homeowners policies exclude damage from pests that builds up over time, though wording differs. Call your insurer before work starts, take photos, keep receipts and ask what paperwork is needed.
Yes. Mice and rats can enter ductwork and leave droppings there, and the heating and cooling system can then move dust and odor through the house. Cleanup may include treating vents and duct openings.
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.
Food, dishes and shelves that rodents touched are sorted. Items that cannot be sanitized are discarded, and hard surfaces are cleaned and disinfected. Anything in sealed containers can usually be saved.
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.
