A thermo fogger heats up a deodorizer oil and expels it in a fog/smoke manner which penetrates in the floor and walls for a long lasting fresh smell.

In an area of high moisture and humidity like that, the foam will hold the water.

I'll cite the highly dramatic strip search, with female officers present, of the woman who cops "mistook" as an aggressor (in other words, she was aggressive to the responding officers which makes her an aggressor) where the documentary maker showed the husband saying, "She felt penetration" and referring to it as a "rape".

Smoke penetrates everything: insulation, carpets, any unsealed wood framing-interior of cabinets-lite fixtures, hvac system, etc.

The foundation problems happen in the DFW area when the soil is not kept at a constant moisture content. 

Provide this information to your buyers along with what you did to remove the moisture problem. 

They used thermal imaging and moisture meters to investigate water damage claims.One of the biggest problems he found consistently was in MDO absorbing a lot of moisture.
