Scratching sounds or a pest sighting near a register do not prove rodents are inside the ducts. Rodent activity should be assessed by a pest professional; duct cleaning is not pest treatment and does not prevent rodents from returning.
If droppings or nesting material are found
CDC says not to sweep or vacuum rodent urine, droppings, or nesting material because that can put contaminated particles into the air. Do not disturb material found inside ductwork; arrange an appropriate pest and HVAC assessment. CDC's rodent guidance describes possible exposure routes but does not establish that every infestation carries a particular disease.
After pest activity is addressed, document any torn, disconnected, or contaminated duct material and price cleaning, repair, or replacement separately. Do not assume that a chemical fogging treatment will neutralize airborne pathogens.
