What Temperatures Will Kill Bed Bugs. 100% Death Rate 115 °F or hotter - All bed bugs (and eggs) will die within 7 minutes of exposure. Most will Die 113 °F to 115 °F - Bed bugs will begin to die out, but a few may survive. No Effect 61 °F to 112 °F - Bed bugs will be able to survive and flourish. Enter Hibernation Stage 14 °F
The length of time that it takes heat to kill bed bugs and their eggs depends on the environment in which you find the bed bugs. Of course, the answer depends on where the bed bugs are.
Can Hot Temperatures Kill Bed Bugs? While they grow and reproduce best at temperatures around 80°F, bed bugs can thrive across a range of climates for relatively long lifespans compared to other similar bugs. Once temperatures begin to climb above 100°F, bed bugs start to lose their ability to function.
Will Steam Kill Bed Bugs? The short answer to this question is yes, steam is a successful heat treatment that kills bed bugs. There are, however, a few caveats to that answer. You can't just blast a shot of steam at an area and eradicate all the bed bugs located there.
For cold temperatures, there exists some controversy over its effect on bed bugs. Some people believe cold temperatures are as effective as hot temperatures in bed bug removal. However, the truth is these insects can adapt to lower temperatures but up to 48 degrees Fahrenheit.
The steam temperature must be at least 130 o F but should not have a forceful airflow, or it may cause bed bugs to scatter. Use a diffuser to prevent scattering. Use a diffuser to prevent scattering.
