Help me get the smell out..

[Kay Ferdous]

So I'm flipping a house in Long Island, NY. House had been abandoned for couple of years.
When we first went in.. House had this horrible smell. So threw everything out and gutted the whole house to the stud.  we had realized that racoons got behind the wall and made a nest. There was feces all over the place and racoon urination on the insulation.

Smell is lot less but its still lingering little bit.  it feel like its coming from some  of the studs.. (maybe).

Any idea, whats the best way to get rid of this smell for good ?
