Ok...anyone ever delt with bed bugs before??

Amy
I'm on almost month 3 with bed bugs. My landlord moved me and my family into a newly remodeled unit that has bed bugs. I don't know how it had bed bugs before, but they even checked my old place and I didn't have them. 
Now I'm slowly going into month three with this. I just found two more in my couch. The exterminator has no idea what to do because he has done literally everything legally he can do. He said my couch should be glowing by now. Well, after finding two more in my couch, twice a week sprayings, dried my clothes so many times that most are now fried beyond recognition, AND 4 heat treatments, I still have them...
I'm very OCD too so it's not because of filth. In fact, that's why I keep finding them is because of my OCD. The bed bugs are even avoiding all the traps the exterminator has left behind!!! 
I think these things are indestructible. Seriously. Scientists need to study these bugs. 
Anyone else go through this? And what worked for you??
And yes, now they are throwing away my couch tomorrow and switching me to a new unit.
