Abstract
A method of pest control which includes forming an enclosure of flexible heat resistant flexible material or fabric about articles forming a working load and heating atmosphere of the enclosure to a temperature which is lethal for the pest being exterminated, and maintaining this elevated temperature in the loaded enclosure for a period sufficient to bring complete working charge to a lethal temperature of 130° F. and maintaining this temperature for at least ten minutes. The treatment is undertaken after determining the air penetration parameters for the enclosure, so as to be able to determine the CFM requirements for achieving an air flow rate of between 10 and 50 air changes per hour in the enclosure, and preferably between 30 and 50 air changes per hour. Heated outside air is introduced to the enclosure at a temperature of at least 200° F., with the temperature in the enclosure being safely elevated until the air temperature reaches the lethal level. A temperature-sensing device may be operably coupled to a heater control, which in turn permits control of the heater/blower system, the sensing device being positioned in the enclosure such that articles comprising the working load in the enclosure attain a lethal temperature.
