Sudden exposure to high heat can kill bed bugs. Bed bugs which get the full force of directed steam over 130 degrees will die instantly. Bed bugs which are deep inside cracks and crevices or who can manage to move away from steam or directed heat will do so. Bed bugs can move fairly fast when motivated.
Bed bugs will move away from heat that comes at them from one direction. Directed heat can force bed bugs from one area of a home to another or from one apartment or treated room in a large building to previously non infested areas.
Gradually increasing heat temperatures may take many hours and much higher termperatures and may not work at all. There is a growing body of evidence that bed bugs get aclimated to slowly rising temperatures.
Bed bugs will run from heat if it only comes from one direction. To work, high heat treatments need to reach the bed bugs from all directions.
Some experts claim that heat treatments fail as much as 20 to 25% of the time.
Heat treatments may or may not be combined with the use of pesticides. If you are already going to be using pesticides, why not save yourself thousands of dollars and give them a chance to work first?
Heat treatments are very expensive. To work well, they need lots of very expensive equipment. Even if they do kill all of your bed bugs, they leave no residual. If you have bed bugs somewhere else, such as in your car you can reintroduce them back into your home. If you travel, or if you brought them home from work....
A true fumigation where they put a tarp over your home has been proven more effective, costs less, and can be acomplished using a fraction of the energy. |
