While nearly everyone has a kitchen freezer, these are not well suited to kill bed bugs 100% in a timely fashion due to the variations in temperature as the door opens and closes.
The researchers recommend placing bedbug-infested items in the freezer in plastic bags for two to four days, depending on the freezer's temperature.
Bedbugs survive cold, but not for too long. Not addressed, though, was whether even lower temperatures might kill the bugs faster. Perhaps a carbon dioxide fire extinguisher (-66° C) or liquid nitrogen (around -200° C) could kill in an instant. Items that wouldn't fit in a fridge could then be disinfected within moments.
