Treat Bed Bugs

My neighbors across the hall had bed bugs and I saw them dragging out their mattress to be thrown away because the bed bugs had colonized inside the mattress. How do I prevent them from getting inside my mattress or box spring?? My mattress cost me about $1,500 and I really don't want to face the thought of disposing it.

Keep the whole room clean. Vacuum not only around and under the bed, but also baseboards, closets, regularly clean drawers, etc. Here's a website:
