When Bed Bugs were re-introduced to the United States in the 1990's, we didn't have any insecticides labeled for the control of Bed Bugs.  Today we have many.  Unfortunately, most belong to 2 chemical families, pyrethroid and neonicotinoid pesticides, both of which Bed Bugs have developed resistance to.  As such, as a responsible member of the pest industry, we rely on materials and methods that bed bugs cannot develop resistance to such as HEAT and AMORPHOUS SILICA GEL DUST treatments.  Both methods eradicate bed bugs by simply drying them out rather than involving toxic pesticides.
