Chances are good that by the time you're done taking down the wallpaper, the plaster will be ready to go as well.Otherwise, I stand by my old tactic of a garden sprayer with a lethal combination of water and industrial-grade paint remover, sprayed on nice and thick after running over the wallpaper with a tiger claw.

Why not hire a pest control company to do a quick spray and inspection instead of a more expensive more time consuming cleaning?

Everything has a finite lifespan.If you get a lot of spray you can expect to paint the house more often.

You then go around the room and make sure counter tops, baseboards, shelving, walls have not been sprayed on.

We try to make our Master Baths a WOW feature of the home, so the master shower gets MULTIPLE spray heads and instead of the TIRED OLD framed in tub, we will be using a FREESTANDING tub... 

It couple be granite, appliances, flooring, or some unique feature like a shower spray. 

My first thought is to frame in the smaller unit, then use spray foam insulation to seal it up efficiently.

Had company spray and then removed everything from cabinets, kitchens, flooring, etc.!

We have a professional pest control company check everything, set traps and spray for bugs every quarter to mitigate issues.
