A PROFESSIONAL CAN RUN INTO DIFFICULTIES IF HE USES THE WRONG METHOD
Thermal vaporisation ''Dry" steam or steam??? A limiting choice that is all too often put forward by people claiming to be professionals, but which almost never produces results. In Villefranche-sur-Saône, north of Lyon, a primary school is currently closed for the second time since the start of the school year after bedbugs were rediscovered. An initial treatment, including thermal spraying at 90 degrees, had been put in place to allow classes to open for the start of the new school year. With the help of a sniffer dog, the City ensured that the pests had disappeared. At the end of September, however, bedbugs reappeared and the school was closed. A municipal hall was requisitioned to accommodate the children who could not be looked after by their parents.
