Beg bugs are less susceptible to freezing temperatures than previously reported, says research.
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.
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.
