Tracy, here is a link I hope it helps with some of the confusion about Parvo, and also breaks down what can and cannot be expected now that your home has been exposed.

You may also want to try Kenic Parvo Lan, I have been using it for many years, I am allergic to bleach so I needed an effective killer. I also add it to my carpet cleaning solution.

I do hope things look up soon! Hugs to your guys.
