How to remedy a smelly house

[Brad Miller]

Good evening all, it’s my first time to Bigger Pockets forum. After 2 books and many Podcasts, I bought my first flip property. Shortly after clearing the hoarders things, we found animals(raccoons most likely) were living in the attic. I removed all sheetrock in the ceilings and all old insulation and bleached and cleaned, but after putting up new sheetrock, finishing, and priming and painting, the smell still remains upstairs. I removed all flooring but I think the smell is in the subfloor. Any ideas on what to use to remedy the smell? Any advice would be appreciated!
