Flooring

• For pet odor in carpeting, an extractor or a wet vacuum can pull much of the staining out of the carpet. Afterward, treating the stained, smelly area with an enzymatic cleaner will remove any remaining pet odors. Wood flooring might need a new layer of varnish to seal the wood and block odors.
  
  

Walls

• If pet odors are coming from the walls of your new home, find out what kind of paint you have on the walls. Some washable enamel paints can be washed with enzymatic cleaners, which will remove the odor. Other paints might need to be reapplied, according to the Humane Society.
  
  

Considerations

• If you have pets, it is important to remove pet odor so your pet is not tempted to cover up the odor with its own urine, according to the book "Your New Dog" by Susan McCullough. In cases where the pet odor is coming from the padding that lies under the carpeting, you might need to remove it and the old carpeting to truly eliminate the odor.
