Disclosed are heatable enclosures useful in treating materials for eradication of pests. Specifically, a heating layer which can be fitted or retrofitted into a numerous and wide variety of containers and enclosures, such as suitcases, boxes, trucks and trailers, which are operable to heat the enclosed space of the container to treat heatable materials over a period of time to eradicate pests. Heating films can be utilized that are inexpensive and lightweight.

The system of claim 1, wherein said insulating layer provides heat transfer from said heating layer to said exterior surface to elevate the temperature of said external surfaces to at least 45° C. 13. A suitcase for killing pests on heat treatable materials, the suitcase comprising: a suitcase enclosure configured to receive said heat treatable materials, said suitcase enclosure including (1) a main enclosure comprising a plurality of sides defining an interior space to receive the heat treatable materials, and (2) a hinged lid positionable to close the interior space of the main enclosure, said main enclosure and hinged lid having a plurality of layers, including:an exterior surface layer having an outer surface and an inner surface, said inner surface disposed relative to the interior space;an insulating layer disposed in said interior space adjacent said inner surface; anda heating film configured to receive electrical current and to generate heat, said heating film being disposed in said interior space along said insulating layer such that said heating film is disposed on said hinged lid and on the plurality of sides of the main enclosure; andwherein said insulating layer (1) traps sufficient heat from said heating film within said interior space of the main enclosure and (2) provides heat transfer from said heating film to said exterior surface layer to elevate the temperature at said outer surface; anda control device operatively coupled to said heating film, said control device configured to control the electrical current to flow through said heating film so that (1) said heat penetrates and heats said heat treatable materials when disposed in said suitcase when said hinged lid closes the interior space to a sufficiently high temperature, for a sufficiently long period, to kill bedbugs on the heat treatable materials and (2) said heat transfers to said exterior surface to generate a temperature at said outer surface sufficient to kill bedbug eggs. 14. The suitcase of claim 13 wherein said heating film includes resistive heating elements. 15. The suitcase of claim 13 wherein said hinged lid attaches to said main enclosure via matably lachable parts. 16. The suitcase of claim 13 wherein the plurality of sides of said main enclosure form four side wall portions and a bottom portion of said main enclosure. 17. The suitcase of claim 16 wherein said heating film is disposed along said four side wall portions surrounding the interior space, disposed along said bottom portion. 18. The suitcase of claim 13 wherein said suitcase enclosure is rectangular in shape defining a rectangular shaped said interior space. 19. The suitcase of claim 13, wherein the heating film comprises an electrically resistive ink layer. 20. The suitcase of claim 13, wherein said insulating layer provides heat transfer from said heating film to said exterior surface layer to elevate the temperature of said outer surface to at least 45° C.
