Bed bugs

So I need all the help I can get. I know this is the last place to out this but I've posted everywhere with no luck. I moved in with some people who own a trailer/mobile home and noticed they have bed bugs. They refuse to let me get the house bombed because of the dogs and the babies so I am going to buy encasements for the mattress and the box spring in my room but the problem isn't the bed. They have wooden walls!!! And upon further investigation I noticed tiny tiny tiny white oval eggs in some of the cracks and crevices on the walls. I'm so devastated because I have EVERYTHING I own in there and I don't know what to do. Is there any sprays that I can use to kill the eggs or adults on contact? Any dusts I can use on the walls?? Any advice is definitely welcome.
