I have never had a dog with parvo, but from reading other post about cleaning is.
You need to clean everything in the house.
All hard surfaces need to be clean with bleach water, don't dry, let air dry.
You need to toss all the dogs old bedding, toys, ect, and buy new ones.
Wash everything in that can be washed in washer with hot hot water.
Spray all couches, bed, ect with lysol until damp and let air dry.
Shampoo you carpets with hot water, and some kind of disinfect soap.
I know I read there is also a product for cleaning that is made to kill the parvo virus. Then also as you know, don't bring any new pups in your house for a year.
Here is an earlier post about cleaning Parvo
