Freakedoutwife on "Husband undoing all my efforts!"

First Post- Need to vent:
Just found out that we have bedbugs for the first time ever! I work one full time job and one part time job and have a 2 hour round trip commute to both jobs. We have 3 kids and can't afford an extermator. I have been cleaning nonstop, keeping laundry bagged, and caulking every Crack in the house. I am OCD and have Generalized Anxiety Disorder. Husband has severe ADHD and refuses medication. He is a carpenter so he is always going into questionable homes (frequently rental properties between tenets). My steamer broke so now I am wanting for my new one to arrive (it hits 200 degrees!) and I ordered Cimexa as well. I have already placed DE around all the walls and I'm washing bedding at least every other day. I believe he brought them home because we found them in our room. Of course I freaked out and cleared out the room. I bagged everything I removed and knotted the bags up very well. Husband at that point was bothered by the bugs too so he was also so bagging things up. Problem ... I didn't realize he was leaving the bags open! Now the whole house is contaminated! Well that was 10 days ago. Now the big problem is he's not helping with the war on bugs, in fact instead of untying the bags to get clean cloths out he rips them open, strings cloths out and leaves them on the floor. He gets mad when I ask him to to remove his cloths after work and bag them. He's now sleeping on the couch and tossing his bedding on the floor in the morning and leaving it there all day. One night I was so upset about the bedbugs I was in tears not wanting to go to bed and he was making fun of me about it. I feel like I will never get rid of the bedbugs because he destroys my efforts and puts no effort into helping me. I'm an emotional wreck at this point. I want to just move me and the kids out and leave him there with the nasty bedbugs but realistically that's not going to happen. I feel like I'm going to have a mental breakdown and I can't tell anyone about it because it's to embarrassing. I don't understand why he is making this even harder to deal with! I haven't even had the chance to start the cleaning process upstairs yet! Anyone have a spouse working against you're efforts to get rid of the bedbugs? How did you get them to stop making it worse and start helping? I have been doing research on do'so and dont's and he just gets mad when I tell him the do's and dont' about getting rid of bedbugs. I'm about to freaking lose it!
