How to Kill Bedbugs in the Freezer?
To adopt this method, you simply have to remove unnecessary covering from an infested item (to avoid insulation) and place it in the freezer at a temperature below 0 degrees Fahrenheit or around -20 degrees Celsius for about a couple of weeks.
The process works faster than this (approximately 72 hours) but to be on the safer side, it is better to wait longer. Larger items would require more freezing time, so you might have to keep them in the freezer for longer.
However, when carrying out this procedure, avoid temperature fluctuations because they can provide the opportunity for reheating, thereby disturbing the mechanism of killing through freezing. It is for this reason that people tend to discourage the use of household freezers for getting rid of these pests.
This method is believed to be effective in killing bed bug nymphs and eggs more readily rather than the adult bugs. In addition, the procedure is more suitable for items that can not be heat treated or laundered.
So, important tips on how to kill bed bugs in the freezer are maintaining the required temperature consistently, removing plastic or paper coverings from the items and sealing them in zip lock bags before placing them separately (not bunched together) in the freezer.
