Does the cold kill bed bugs?

The short answer is “yes”, but really it’s not an effective method depending on the situation.  It has to stay below freezing for a week.  Let us set the stage, in the dead of winter, in a storage unit that isn’t heated, it gets below and stays below freezing sure it might work.  However, the conditions have to be perfect.  Solar loading during the day can heat it up again above freezing.  Trying to maintain the perfect conditions are almost impossible and the freezing method via mother nature takes a long time.  Not just an hour, but a week.  The colder the better and the quicker they die but it still takes time.  If you live in the north and there’s a hard cold snap (this means its super cold, well below 32 degrees Fahrenheit, for 24 hours a day for a week) it could work.  Now let’s set expectations, People who live in the South consider a hard freeze around 32 degrees Fahrenheit, or at least my weatherman does, which is not the same as what a Northerner considers a hard freeze.  Turning your heat off in your home and letting your pipes burst is not a viable option.  So don’t do it.  Some companies do use super cold generators to freeze the bed bugs but as I have written previously every single bug and egg needs to be touched to kill it when using super cooling generators or chemicals.  Using cold is doable if you can take the infested items outside and leave them to freeze and can avoid solar loading.  However, it’s not a whole home remedy unless an exterminator comes with special equipment.  See additional posts for other options.
