Get rid of bed bugs

Will we ever get rid of bed bugs? Why is it so hard to get these critters under control? I think it is mostly because of the fact that we have become such a chemical paranoid society. These days exterminators use IPM. They flash their flash lights and put out their glue traps and monitor their monitors. Hardly any chemical is used. So why are they so resistant to our chemicals? These are battle worn bugs that have been around for a trillion years. They aren't going to go without a battle, and that is just what we are trying to give them. Hopefully we will come up with a proven battle plan to rid our beds of these bugs that seen to have taken over.
