I contacted a company called Spray Nine in regards to a product I use in my home frequently (it kills many nasty things like MRSA and is approved for hospital use) in regards to it's effectiveness on Parvo.
Here is the reply I received:
We have not tested Spray Nine for Parvo – we focus on viruses and bacteria that pose health risks to humans –
FYI, bleach does NOT kill Parvo, either
With regards to Parvo, there are disinfectants that have the Parvo claim (some are like 10-20 minutes)-I would suggest you contact a few businesses in the industry of servicing veterinary businesses – they may recommend one – probably several would be surprised to hear that bleach doesn’t kill it.
I thought this would be some good information to pass along to anyone who has had Parvo in their home, or has had any kind of exposure to it...
Here's some more information on picking a product to actually kill Parvo.
