You can draw bed bugs out of hiding, by using their instincts against them. They are drawn to heat, carbon dioxide, and like certain smells. You can buy CO2 and bed bug heat traps, that over time will trap a significant percentage of the bugs in a room. Unfortunately, Only the adults come to the trap and are killed. So, the eggs and nymphs are unaffected. It takes many months before they enter the traps. By which point they may have already laid eggs, which starts the infection cycle again.
