You may recall how Dr. Michael Potter comments on thermal treatments for bed bugs:
STRUCTURAL HEATING. Elevating the temperature within buildings has been used to eradicate pests ranging from grain insects to termites. Structural and containerized heat treatments are also being developed for bed bugs. Companies such as TempAir (Burnsville, Minn., 888/838-4035) have begun licensing the patented technology to interested pest control firms. Portable heaters and fans are used to gradually heat the air within rooms to about 125 to 130°F while monitoring with strategically placed sensors. A licensing and royalty fee is typically required along with the initial equipment purchase.
While heat treatments hold promise, eliminating infestations by raising the temperature within a building may not be so easy. As observed with cockroaches, bed bugs may seek out cooler areas as the temperature within rooms builds. Whether some bugs will be able to survive by moving to cooler locations (including adjacent units) still needs further study.
This describes how the process works. Please do not try to replicate this in your home — it is dangerous in terms of fire, may well be illegal, and may well cause your bed bugs to thoroughly spread throughout your home or into walls, making them harder to eradicate.
TempAir does not offer the actual services, though. You may be able to call them to find a PCO or operator in your area. Apparently Excelsis is using bed bug dogs to find bed bugs and TempAir heat technology to bake them to death in Chicago.
Last year, one of their machines was tested by Purdue researchers. I hope we will see the results soon.
