I haven't had a problem with bedbugs but bought a powerful ozone generator a few years ago. It seems to help with dust mites, oder and generally sanitize. It's run a couple of times a month while at work. My understanding is these can kill bedbugs if you get the concentration up high enough. Be careful, especially in an apartment. Ozone can be hazardous. It degraded back into breathable oxygen pretty quickly but you don't want to stay in the room with it or have it bleed over to the neighbors and damage their lungs or anything.
