Canine parvovirus, or parvo, is a highly contagious and potentially deadly virus that affects dogs. If your pet has been diagnosed with parvo or you suspect exposure, disinfecting your home is essential to prevent further spread. Parvo is notoriously resilient and can survive in the environment for months, making thorough cleaning critical. This guide will walk you through proven, expert-recommended steps to disinfect your house effectively and keep your furry friends safe.
Understanding Canine Parvovirus (Parvo)
What Is Parvo?
Parvo is a virus that attacks a dog’s intestinal tract and immune system. It is most dangerous for puppies and unvaccinated dogs. The virus causes severe vomiting, diarrhea (often bloody), and dehydration, and can be fatal without prompt treatment.
How Parvo Spreads in the Environment
The virus is shed in the feces of infected dogs and can contaminate surfaces, soil, food bowls, bedding, and even human clothing. Because parvo is very stable outside the host, it can survive for months in the environment.
Why Disinfecting Your Home Is Crucial
Risks of Parvo Contamination at Home
If parvovirus particles linger in your home, they pose a serious infection risk to other dogs. Even indirect contact with contaminated surfaces can result in transmission.
How Long Parvo Virus Survive on Surfaces
Parvo can remain infectious on surfaces for up to a year in some cases, depending on conditions like temperature and humidity. This longevity underscores the importance of thorough disinfection.
Essential Cleaning Supplies and Disinfectants for Parvo
Recommended Disinfectants
- Bleach solution: A 1:30 dilution of household bleach (5.25-6.15% sodium hypochlorite) is highly effective.
- Accelerated hydrogen peroxide products: These are safer and effective alternatives.
- Quaternary ammonium compounds: Can be used, but may not be as effective alone.
Tools and Protective Gear
- Rubber gloves
- Disposable masks
- Scrub brushes or sponges
- Buckets and spray bottles
- Disposable towels or paper cloths

Wash bedding in hot water (above 140°F/60°C) and dry on the highest setting.
Step 11: Practice Personal Hygiene After Cleaning
Wash hands thoroughly, change clothes, and clean footwear to avoid cross-contamination.
Step 12: Repeat Cleaning Routine as Recommended
Disinfect your home repeatedly over several weeks to ensure the virus is eradicated.
