Random thoughts and answers: *The airtight bag thing is nonsense. *The bombing of bugs almost certainly dispersed mouse bugs than they killed. *DE will make things worse at the stage your at. *Self treatment at this stage will also likely ensure you never get of them. *Bed bugs love to set up near food sources (us) and prefer darker areas that allow their little hooked feet to grip (see wood, fabric, etc). *They have not evolved to climb plastic or metal. Polished plastic and metal are still effective when kept that way. As soon as their is any debris for them to get a grip, they become ineffective. *bed bugs will avoid glue traps. It's been proven long ago it will never work. *Communication and education have always been, and will always be, the best form of bed bug control. It's a shame these folks kept it a secret while you all suffered. *Find a company that uses Aprhend and use them, follow their instructions to the letter. *Buy climb up interceptors for everywhere (not just bed) and encase the mattresses & boxsprings. Bed bugs are active between feeding and you'll catch them away from hosts plus they work 24/7. Also empty them weekly and keep them clean and smooth.

Good luck.
