ABSTRACT:
Processes and devices for producing a heated non-flammable gaseous fumigant for structural fumigation use by the application of a carrier gas, such as carbon dioxide (102), to a heater (103) either prior or subsequent to mixing the gas with a toxic agent gas, such as methyl bromide (213), such as by means of a mixer (214) and applying the mixture of gasses as a structural fumigant to eradicate target pests within a structure (106). In the preferred embodiment, the gaseous carbon dioxide is formed by flashing liquid carbon dioxide (614) directly to the gaseous state in a heater (630) prior to being mixed with methyl bromide (654) in a mixer (648) and applying the mixture of gasses as a structural fumigant within a structure (668).
