Washington – While it is suggested that exposing bed bug-infested clothing or other small items to freezing temperatures can help kill bed bugs, a new research has found that bed bugs may be less susceptible to freezing temperatures than previously reported.

Bed bugs, like many other insects, use a “freeze-intolerant” strategy against the cold, meaning they attempt to protect themselves from freeze injury by lowering the freezing point of their body fluids.

For this study, the researchers evaluated the supercooling point (SCP) and the lower lethal temperature (LLT) for all life stages of bed bugs, as well as their potential to feed after exposure to sublethal temperatures.

The authors found that in order to achieve 100 percent mortality, a minimum exposure time of 80 hours at minus 16 degrees celsius is required for all life stages. Temperatures below minus 15 degrees celsius are sufficient to control all life stages of bed bugs after 3.5 days, while temperatures below minus 20 degrees celcius require only 48 hours. They also observed bed bug eggs surviving in short-term exposures to temperatures as low as minus 25 degrees celcius.

Homeowners can place bed bug-infested items in a freezer to destroy them. However, the authors recommend that the items be placed in plastic bags and that they remain in the freezer for 2-4 days, depending on the freezer’s temperature.

The study was published in the Journal of Economic Entomology.
