A) Heat treatments are expensive and less reliable than chemical treatments. Reason being; When the correct chemicals and procedures are used, you receive a residual affect (the product continues to work AFTER the treatment). With heat, there is zero residual affect.
B) Heat treatments demand A LOT of prep work (just to have a chance to work correctly). Reason being…the bed bug itself – not the air – must reach a temp of at least 140-150 degrees and be sustained for numerous hours (this means the air temp must be much higher to penetrate walls, box springs, etc). Part of the prep process involves removing anything plastic from the home, to prevent it from melting (including mini blinds, TV’s, remotes, etc). You basically need to move out for a day.
C) Insulation on wiring inside walls begins to melt at 170 degree. This can pose a short circuit issue in the future and possibly a fire.
D) Many cases have been reported that DURING treatment homes catch fire: http://www.nbcnewyork.com/news/local/Bed-Bug-Treatment-Radiant-Heat-Fire-Ice-Debate-Hazards-214087061.html Professionals using heat treatments have burned down buildings in other cities. See: Dayton, Ohio: A bed bug heat treatment set fire to a home. Manchester, New Hampshire: Blaze caused by heaters used by pest control company. Edmonton, Canada: Radiant heat treatments caused a large blaze that had 60 firefighters called in to put out a fire in a four story apartment building that had $3.5 million in damage. Cincinnati, Ohio: Bed Bug Heat Treatment burned down a home. AND A HEAT TREATMENT COMPROMISES SAFETY AFTERWARD: IT MAKES HOMES LESS SAFE AFTER TREATMENTS ARE COMPLETED Bed Bug Heat Treatments Often Damage Sprinkler Systems – so the treatment increases fire risks even after the bed bug service is complete. According to the National Pest Management Association, Heat also compromises the future effectiveness of a sprinkler, which may result in property damage, or human injury or fatality. There also is potential liability if a PMP disables a fire suppression system without an appropriate license or, if while the treatment is being performed, a fire occurs while the system is disabled. The NPMA warns in its bed bug protection guides that 220.127.116.11.6. Potential heat damage to certain materials, including the risk of activating automatic fire suppression systems (sprinklers). Care should be taken to safeguard these materials and systems. (page 13) The treatment area may also become a fire hazard after treatment because the heat dries out the wood beams and furniture. Put simply – heat treatments are not worth the risk to your life, health, and home- or to that of your neighbors and firefighters.
