Cimex Technologies operates with the highest level of commitment andintegrity. We guarantee that our expert advise and heat exterminationsystem is the best choice if you have bed bugs. We promise to show you bedbugs before we take on any job. Pesticides have become ineffective as bed bugs have developed resistance, andpesticides don't work without direct contact on insects. Compare this to heat: Bed bugs cannot become resistant to it, and heat waves get everywhere. We kill bed bugs in the infested space and surrounding walls byheating the space to a temperature above 125°F, killing all bed bugs and their eggs.
