Outside-In Approach

Benefit of Outside-In Approach

Implementing a comprehensive program utilizing an Outside-In Approach can greatly improve your efforts towards large fly prevention in your facility. 

Benefit of Outside-In Approach

Large flies, also known as filth flies, include houseflies, bottle/blow flies and flesh flies. An Outside-In Approach focuses on finding the root cause of large fly activity and solving issues before flies reach the interior. This approach requires a good partnership between you and your pest management provider. There are three areas of focus working from the outside to the inside of your facility:

PREVENT entry opportunities.
Open doors are the primary route for large flies to gain access to the inside of your facility. Finding ways to minimize open-door time is essential, but often there is no other choice. In areas where there is high exterior pressure and doors are opened repeatedly, other options such as vestibules, air curtains, plastic strips, etc. must be considered. 

REDUCE fly pressure on the exterior.
Good sanitation on the exterior is the key to reducing fly pressure. Targeted treatment of exterior surfaces and use of Ecolab Fly Stations and Disposable Fly Traps in areas where large flies congregate (such as the dumpster corrals and garbage areas) will help reduce the number of flies near entrances, reducing large fly pressure. 

ELIMINATE activity on the interior.
If large flies are gaining access to the interior of the facility, the best options are to look for better ways to ‘reduce pressure on the exterior’ and ‘minimize entry opportunities.’ Killing flies inside is the least effective way to address a large fly issue.
