Reducing Fly Count by 73%

Key Objectives

  • Reducing fly ingress
  • Reduce fogging
  • Reduce need for additional electric fly killers
  • Protecting Product Integrity

The Challenge

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.

The Solution

Following a detailed site survey, Rite-Hite (Enershield partner) specified and installed an Enershield DSH-120 air barrier and positioned in front of the existing rapid roll door leading from outside to the raw products collating area. The air barrier technology creates a highly efficient seal creating a virtual door over the open doorway. Detailed fly counts from the electric fly killers in the collating area were taken illustrating a 73% reduction in fly numbers when comparing the 12 months before and after installation. In addition, since the installation of the Enershield air barrier, there has been no need to carry out any additional fogging.
