Does Cold Weather Kill Bed Bugs?

As the seasons change and winter arrives, you may be counting on the weather to solve your pest struggles. It’s not a far-fetched idea to think that a little cold is all it takes to scare the creepy-crawlies away; unfortunately, the best defense against bed bugs is not by freezing them out. 

Can Bed Bugs Survive in the Cold?

Even though freezing has the potential to kill bed bugs, it’s not the most effective method available. Bed bugs have an annoying superpower that allows them to lower the freezing point of their bodily fluids, transforming them into freeze-resistant mini-monsters. Temperatures have to be extremely low for long periods of time to kill bed bugs, which means that your house would have to be at a resting temperature of 3.2 degrees Fahrenheit for a minimum of 80 hours for all your bed bugs to die. Bed bugs can survive cold temperatures for short periods of time, so their exposure to the freezing process has to be extremely prolonged for this method to be effective. 

This information suggests that you would have to live in arctic-like conditions for the bed bugs to be killed naturally. If you’re going to rely on this method, understand that the cold weather alone is unlikely to kill bed bugs. When out in the wild, bed bugs feast on birds and mammals, and can latch onto their prey to survive the cold. If you have items that you fear may have bed bugs on them, put the items into bags and place them in a freezer for several days.
