The operative phrase here is for long enough to kill bed bugs with cold they must be exposed to extreme cold for several days before they die.
What cold temperature can kill bed bugs.
The study ultimately proved that the adult bedbugs could be killed by cold only through exposure to temperatures of 16 deg c or lower for a period of at least 80 hours.
Bed bugs can survive in cold environments for a long period of time without food.
The best temperature for killing bed bugs in a freezer is 0 f.
Like extreme heat extreme cold can be fatal to bed bugs over time.
However they cannot live long in extremely cold environments.
Interestingly temperatures between 60 f and 80 f will make bed bugs grow slower and temperatures between 25 f and 60 f will result in death in weeks or months.
A similar process can be used with heat.
It s true that if you leave bed bugs in an inescapable package in extreme temperatures below 32 f 0 c for long enough they will freeze to death.
Temperature that kills bed bugs.
Adult bed bugs die at 119 degrees fahrenheit and their heat resistant eggs require temperatures upwards of 125 degrees.
On the other end of the spectrum the temperature at which adult bed bugs freeze to death is 19 48 f 28 6 c.
Using freezing cold temperatures to kill bed bugs is one option.
However the truth is these insects can adapt to lower temperatures but up to 48 degrees fahrenheit.
Even then some may survive.
Put an infested object such as bedding or pillows in a sealed plastic bag then put it in a freezer at zero degrees fahrenheit for about four days.
Some people believe cold temperatures are as effective as hot temperatures in bed bug removal.
According to various scientific studies the temperature that is lethal for adult bed bugs is 118 94 f 48 3 c.
This is however possible for only a few days.
Can cold temperatures kill bed bugs.
A cold temperature of 16 degrees celsius in 80 hours.
The eggs of the bugs survived in short term exposure to even lower temperatures of 25 degrees c.
Generally mature bugs can survive for a few hours to a few days when exposed to low temperatures.
Although these can be tricky to achieve in a residential setting it isn t impossible.
