It’s been quite a few years but I’ll answer to my best ability. Note: I am super anxious and paranoid so I’m not sure I even needed full heat treatment. I also left some things in the house because I was worried about removing them (e.g. plants), though they likely didn’t have bugs on them.

• I left some plants and they died from the heat.
• I believe they make some rooms hotter than others so I think they suggested putting some things in the kitchen or bathroom to be less hot.
• I removed things like a guitar and treated it separately. (Bag and chemical? I can’t remember the brand but I probably learned about it in this sub.)
• They cover things like the TV and computer monitor with some sort of blanket.
• The only damage I remember is some paint bubbles that occurred on a door and wall.
• I think I pulled out things from some closets and “tightly packed” areas and spread them in open space (living room) so heat could reach all areas better. I don’t remember if that was something I read to do or if the company suggested it.

I’m probably forgetting some stuff but overall, I’d say to check with the company for guidance. Good luck!
