However, temperatures below -4 degrees Fahrenheit (-20 degrees Celsius) will kill them in just 48 hours.

According to a new study, freezing bedbug infestations may not be as successful as initially believed.

Researchers discovered that the blood-sucking parasites had a significant cold tolerance.

However, with several days of exposure to low temperatures, they will collapse into the cold.

The bed bugs utilize “freeze-intolerant” techniques to live in cold conditions, such as reducing the core temperature of their body fluids.

Moreover, researchers suggested putting all the items infested by bed bugs in plastic to be placed in the freezer.

With that, after 2-4 days, bed bugs present in those items will surely die depending on the temperature.
