Rodents in your air ducts. Is it a real thing? In the fall and winter in Virginia Beach, Chesapeake, Newport News and surrounding areas, rodents will enter a home for shelter. This could mean your attic, crawl space, walls or even your furniture. Air duct cleaning is more than just removing dust from your home. It also is removing rodent droppings and urine that is left behind from a rat or mouse infestation. This is why you should have your air ducts inspected by a company like Universal Duct Cleaning.
