Due to the nature of the product made by this food manufacturer, flying insects are attracted to the facility.  The frequently used, large rapid roll door leading into the building was a vulnerable point of entry. Although, the number of flies getting in had always been kept within acceptable limits, continually achieving these levels meant adding more electric fly killers or periodic fogging.  As part of their continuous improvement programme, the client wanted to ensure that fly numbers, especially those entering the building by this door, could be better controlled. This would ensure they could achieve a higher level of Food Safety Integrity as required by their many high profile customers.
