11.3.3.3.1.


Ensure, through the use of heat sensors, that bed bug harborage areas are raised to a lethal temperature and held for a sufficient period of time to kill all bed bugs and eggs.


11.3.3.3.2. Because some areas are insulated, or slower to heat, sensors should be placed in areas that ensure that the core temperature of the treated item reaches lethal levels for a sufficient period of time.


11.3.3.3.3. Recommended temperature and exposure periods are provided in Appendix B.


11.3.3.4. Heat treatment can be limited by these factors: 11.3.3.4.1.


Insulated areas where it is difficult to raise the temperature to levels sufficient to achieve complete kill.


11.3.3.4.2. Poor air flow in a room or container resulting in cool spots. 11.3.3.4.3. Poorly insulated rooms or containers during cold weather 11.3.3.4.4. Construction features that may contribute to heat loss or insulated cold spots.


11.3.3.4.5. The possible ability of bed bugs to move out of heated areas in whole-room treatments.


11.3.3.4.6. 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.


11.3.3.5. For whole-room heat treatment, the preventive use of insecticide in walls and under carpet edges, prior to treatment, may complement treatment by killing bugs attempting to move away from the heat.


11.3.3.6. Containerized heat treatment can be used to supplement traditional bed bug service by killing bed bugs and eggs in items that are difficult to treat using other methods. 11.3.3.6.1. Typical items to be heat treated include beds, furniture, personal possessions, clothing, shoes, appliances, and equipment.


11.3.3.6.2. Various enclosures can be used including trucks, trailers, shipping containers, storage pods, specially designed self- contained heating units, or tarps.


11.3.4. Mattress and Box Spring Encasements 11.3.4.1. Mattress and box spring encasements can be a useful tool for bed bug control. 11.3.4.2. Encasements create a barrier to bed bug movement in and out of the mattress, box spring, and pillows, by trapping and starving bed bugs inside.


11.3.4.3. Encasements make subsequent inspection easier because bed bugs are more visible on the encasement by eliminating harborage areas in the box spring and mattress.


11.3.4.4. Not all encasements protect against bed bugs; only use those demonstrated as being “bed bug-proof,” “bite-proof,” and “escape-proof.”


11.3.4.5. Encasements allow residents to salvage an infested bed rather than dispose of it. 11.3.4.6. Before encasements are installed, a pest control professional should vacuum, steam or treat the mattress and box spring to remove and kill as many bugs as possible.
