What a mess! That blows. Bedbugs are all over the country these days. They had them at my apt in Brooklyn! Came in under the door. None of our furniture was used. Didn't even know what the bites were from for weeks! Yucko! There's a vinegar water solution you can use on the wood parts that touch the ground once you've fogged the mattress or upholstery. It keeps them from crawling back up again onto the couch or bed.
Sorry you're going through so much stress.

Hope things are better tomorrow.
