A process is provided for determining the amount of sulfuryl fluoride in the atmosphere of an enclosed area that has been fumigated with sulfuryl fluoride (SOF). This process comprises: (A) sampling said atmosphere of said enclosed area to obtain a gaseous sample; (B) selectively removing water from said gaseous sample by passing said gaseous sample through a perevaporation zone to obtain a perevaporated sample, wherein said perevaporation zone comprises a copolymer of tetrafluoroethylene and perfluoro-3,6-dioxa-4-methyl-7-octene-sulfonic acid; and (C) analyzing said perevaporated sample in a sulfuryl fluoride detector to determine the amount of sulfuryl fluoride in said perevaporated sample.

Sulfuryl fluoride fumigation process

A pest control system () includes pest control devices () installed about an area or building (). These devices () each include a bait member and a communication circuit. The communication circuit may be in the form of a passive RF tag that transmits information indicative of bait status and an identifier unique to each pest control device (). A hand held interrogator () is provided to locate and communicate with the pest control devices () via the communication circuit. A data collection unit () to accumulate data gathered from the pest control devices () may alternatively or additionally be utilized. The bait member may be configured with a magnetic component to provide a magnetic signature indicative of the bait consumption behavior of targeted varieties of pest. The devices optionally include one or more environmental sensors to evaluate and predict pest behavior.
