A Termite Threat Calls for a BIG Black Circus Tent!?!

Mom had found some suspicious sand-like deposits near a couple door frames and hired a termite company to come check it out and give her suggestions on what it is and how to fix it.  The guy determined that the sandy stuff Mom had found was in-fact drywood termite pellets and he also found a couple strange mud tube cocoon-like structures that were evidence of subterranean termites that live in the ground.  Long story short, he suggested a combination of in-ground pesticide that would essentially create a protective moat around her house and a tent to kill anything living in the wood.  So we packed up photos and things in plastic to protect them and did all the other preparatory prerequisites from the list the guy gave her, then she packed an "essentials" suitcase and moved in with me for a few days!
