Pest control system

Pest extermination by thermal treatment of pest-host articles isolated within an enclosure and comprising the steps of:

• (a) selecting and isolating pest-host articles to form a working charge;
• (b) forming an enclosure of flexible heat resistant material about said working charge to form a loaded enclosure;
• (c) sealing edges of said flexible heat resistant material to render said loaded enclosure substantially airtight;
• (d) establishing an air inlet port at a preselected disposition in the wall of said enclosure and an air exhaust port in said enclosure wall at a location remote from said air inlet port;
• (e) determining the air penetration parameters for said loaded enclosure;
• (f) determining CFM requirements for achieving requisite air flow rate goal of between 10 and 50 air changes per hour in said loaded enclosure;
• (g) introducing heated outside air into said loaded enclosure at a temperature of at least about 200° F. and at the requisite air flow rate;
• (h) elevating temperature in said loaded enclosure at a ramp rate safe for said working charge until air temperature in said loaded enclosure reaches a desired level at least equal 130° F. while maintaining said requisite air flow rate;
• and
• (i) maintaining lethal temperature in said loaded enclosure for at least 10 minutes while maintaining said requisite air flow rate.
