How Cold Does It Have to Get to Kill Bed Bugs?

Bed bugs are sensitive to extreme temperatures. When correctly applied by an expert bed bug exterminator, both high heat and freezing cold can and will kill bed bugs. In both cases, a certain temperature must be reached and maintained for a specific period of time to guarantee the death of these insects. However, a recent study indicates that bed bugs may be better that previously believed at protecting themselves against low temperatures.

Like many insects, bed bugs have the ability to shield themselves against injury from cold temperatures by lowering the freezing point of their body fluids. As reported by the Entomological Society of America, a new study has been able to document bed bug behavior at various low temperature exposures and durations, providing pest control professionals with reliable bed bug control data.

Study results validate the instantly lethal effectiveness of Stern’s Cryonite bed bug extermination system. Researchers found that at temperatures below 5 F., bed bugs at all stages of development died within 3.5 days. Decreasing the temperature, shortened the necessary exposure time to guarantee 100% extermination; although some bed bugs were able to survive short exposures to below zero temperatures down to minus 13 F. Our Cryonite system uses a carbon dioxide “snow” super-cooled to a temperature of minus 110 F. which instantly freezes and kills bed bugs at all stages of development, including eggs.
