Pumped white vinegar is sufficient but it still has to be done.  

Which vinegar and water with a damp cloth 2-3 times does the trick.

Second thing is to wash ALL window seals and walls, yes walls with either a store bought cleaning aid for smoke or a homemade vinegar solution.

Without boring you with a ton of details, I began a renovation on a mostly occupied building, with a fairly educated budget, an arsenal of tools that would make Bob Vila jealous, a 360lb back squat max, and a belly full of piss and vinegar.  4 months later I am crabby, exhausted, carrying some credit card debt, consuming espresso like water, and just want to lay in a hammock for 3 days and drink myself to sleep until its time to lift weights again, and think about a better way to live.

Sprayed entire area with white vinegar.

Simply moping the walls (bleach, vinegar, or tsp) and cleaning the carpets has worked for me.

I'd work the "you catch more flies with honey than vinegar" angle of luring her into the business by making your excitement and vision contagious. 

Use white vinegar to get to the roots in the wood.

I think $30 worth of honey is reasonable with so much potential vinegar in the equation. 

I'm inclined to say use honey but some have more luck with vinegar.
