Here is another article on how to kill bed bugs which are probably similar nasty critters to kill.

Conclusion:
Recent research has determined the thermal death points (the temperature at which a bed bug dies) for bed bugs and their eggs. The thermal death point is determined by two things; temperature, and exposure time. Bed bugs ex- posed to 113°F will die if they receive constant exposure to that temperature for 90 minutes or more. However, they will die within 20 minutes if exposed to 118°F. Interestingly, bed bug eggs must be exposed to 118°F for 90 minutes to reach 100% mortality. Note that whole room heat treatments (see below) are based on a thermal death point of 113°F, yet these treatments have been very successful. This is due to the use of powerful fans to create convection currents within the heated room. These currents heat the bed bugs very rapidly, thus increasing their mortality.
