No bad experience to report, they where key in helping solve a bed bug problem I would have struggled with (the tenant stayed through the "spraying" process). 

that gets sprayed frequently right up to the edges of the cities.A lot of folks switching to organic/non-GMO cotton around here though.

We sprayed the anti-mold thing to the ceiling. 

A contractor suggested spraying it with a 50/50 mix of bleach and water.

They were very knowledgeable about and sprayed for subfloor eating fungus.

Like @Nathan Gesner said run an ozone machine, and you can purchase specific odor neutralizer sprays like car companies use.

We have learned how to use shields while spraying to not have to tape off hardly anything (maybe certain corners on occasion).  

I don't see many of these in Amarillo....but not there very often and don't pay that close attention.If it is, maybe you could really specialize...and as someone else said if you have truck parking....rent to truckers for the night....or if you are close to Route 66 rent to bike riders passing thru....or focus on any of the other specialties in your area....like including spray paint for the Cadillac Ranch, or balloons if they want to visit the Helium museum...or cool things like that. 

You could do spray foam insulation if  it gets cold in the house.

Try spraying with muriatic acid solution to etch the brick and clear up some (more) of the ivy damage, then power wash with a baking soda solution to neutralize the acid and stop the etching process.
