Pet urine and odors in carpet: what to do and when to call a professional

Updated November 10, 2026 · KeystoneProGuide editorial team

What should you do when a pet has an accident on carpet?

Deal with it straight away, without heat. The Carpet and Rug Institute, the carpet makers' trade association, says to clean new pet messes promptly, and says not to use a steam cleaner on urine spots because the heat will set both the stain and the smell. Its advice is to extract the urine with a wet vacuum and rinse the spot with cool water, and to call in a certified cleaning firm if the odor stays. The other steps below come from the institute's general spot method and from what the allergy bodies say about pets and carpet.

Why not use heat on urine?

The institute's reason is the one above: heat sets the stain and the smell. So tell a company about urine spots before it starts, and ask how it will treat them. The institute's residential standard lists the questions a certified cleaner should ask you, and two of them are whether you have pets, and whether it is a cat or a dog.

How do you treat a fresh accident yourself?

Use the institute's general method for spills, with its pet advice on top.

1. Pick up solids first and scoop semisolids with a spoon.
2. Blot the liquid with a dry white cloth or plain white paper towels until the area is nearly dry. Colored or printed material can transfer dye.
3. Do not scrub or brush. The institute says scrubbing frays carpet and changes its texture.
4. Extract and rinse. A wet vacuum or small hand extractor, then cool water, as the institute advises for urine.
5. Use one spot product at a time, if any. Test it on a hidden area first and follow its directions. The institute warns that layering several spot removers without rinsing between them can set a stain permanently.
6. Blot with clear water at the end to remove leftover product.

The institute recommends products certified under its own Seal of Approval program, including ones designed for pet stains and odors. The U.S. Environmental Protection Agency's Safer Choice program, which reviews every ingredient, has a product category for carpet spot removers as well as carpet cleaners.

Never combine products to make something stronger. The EPA warns that mixing cleaning products, or adding bleach to other chemicals, can create toxic vapors.

Should you use air fresheners or scented sprays on pet odor?

The American Lung Association says to avoid air fresheners altogether, and lists them, along with rug and upholstery cleaners, among products that can release volatile organic compounds.

When is a professional worth it?

The institute names three situations.

• The odor stays. It says to call a certified carpet cleaning firm that knows how to remove pet stains and odors if rinsing does not work.
• Your own treatment has failed. Its third step for any spot is to call a professional once blotting and treating have not removed it.
• Accidents are regular. It says small hand extractors are fine for quick cleanups but do not replace periodic deep cleaning, and recommends professional cleaning every 12 to 18 months, or more often if necessary, in homes with pets. It also says to vacuum more often to pick up hair and dander.

When you call, say how old the accidents are and what you have already used on them. The institute's standard lists "what have you used to try to remove the stain?" among the questions a cleaner should ask.

What does pet odor treatment cost?

The cost surveys price it as an extra on top of a basic cleaning:

• Odor removal and deodorizing: $20 to $40 a room (Angi) or $20 to $40 or more a room (HomeGuide).
• Pet stain and odor removal: $30 to $40 an hour (Fixr).
• Stain removal in general: $40 to $300 (Angi), $125 to $250 (HomeGuide) or $30 to $40 a stained area (Fixr).

Will cleaning out pet accidents help with pet allergies?

Not much, if the pet stays. The EPA says proteins in a pet's skin flakes, urine, saliva and hair can trigger asthma, and that the most effective control is not to have the animal in the home. The Asthma and Allergy Foundation of America says pet allergen clings to carpets and furniture and can cause symptoms up to 6 months after the animal has gone. The American College of Allergy, Asthma and Immunology says that where a pet-allergic child lives with the pet, cleaning the carpet has little effect on the total pet allergen in the home.

What the EPA does recommend for a pet that stays: keep it out of the bedroom of the person with asthma and off the furniture, use a HEPA air cleaner, and vacuum carpets and furniture when that person is not in the room. Carpet and allergies goes into the health advice in more detail, and companies that treat pet odors are on the carpet cleaning directory page.
