It was overwhelming and I tried every product (with enzymes, etc).

The research I did pointed heavily toward enzymes and shellac as the best solutions for penetrated odors like this.

(Cheap way in place of nature's eradactor) as I've read that the enzymes in PERISIL effectively kill all life stages (contract killer) but still Im seriously so close to becoming insane its really bad how much it has affected my mind.

I'm feeling pretty confident about charging for all the labor and materials for the entryway but I am not sure what to do about the carpet.Should I itemize all my costs including my time and the enzyme treatment that didn't work even though I am waiving those costs?

I have seen carpet with odor that can't be removed even with the fanciest enzyme cleaners. 

They make special pet urine cleaners that's suppose to have enzymes that dissolve the urine smells.

We'll plan to treat the floor with some type of enzyme that kills bacteria, but I'm also planning to run an ozone machine.Do you have any recommendations of machines you've used and for how long to run them?

After several rounds of the enzyme scrub with a deck brush, letting it sit, and rinsing thoroughly, the smell went away and the floor was good for the LVP. 

Has anyone had success using enzymes products to open drain field lines on a septic.

Fluids should dissipate into the leech field and solids should be in tank where enzymes can eat them .
