I don't *know* but that's kind of the problem. No one knows where it is. I know an elderly person with a housemate that just moved out. I was thinking about fogging her house for good measure. If he has it and is asymptomatic, it very well could be in the air. But if he is asymptomatic, we would have no idea that he has it.
She's in several high-risk groups, so erring on the side of caution might be a good thing.
The great question is about cleaning surfaces! I figured the answer was yes because if you are using it in your barn/hen house, one goal is the clean the surfaces, but I don't like to assume too much, so I called back and spoke with D.D. (I'm using names because these gals are so friendly and helpful and really give excellent customer service, so here's a shout out to the great employees of Revival!). D.D. confirmed that it does clean surfaces. She also reminded me (good thing, because I had forgotten) to let the solution sit for 15 minutes after activating it before using it.
To recap: put on your mask and gloves, activate it, let it sit for 15 minutes, get everyone out of the house and open the windows, fog for 10 minutes (I will do the upstairs for 10 and the downstairs for 10), leave the house for at least 2 hours, and voila! All done!
