Food safety, hygiene standards, restrictions on the use of rodenticides, etc.: this all has caused in the recent years a higher sensibility on monitoring and more attention to preventative pest control with high quality documentation than before. Thus, the use of pest control products continued to get restricted. In the field of rodent control (sensitive rooms), the use of rodenticide baits has become more and more omittet. In individual cases - depending on standard - even completey prohibited (risk of scattering, etc.). As a result, new ways had to be found to do without rodenticide baits. One way thereby was the use of live or snap traps. Nevertheless, they have to be checked daily in order to remove caught rodents and defang them. Regarding this, the Animal Protection Act hast strict rules. A considerable effort that is time-consuming and cost increasing. The conclusion was: the development of HYGiTEC Permanent-Monitoring.
