Flies are one of the most commonly-encountered pests in and around commercial properties. The threat of a fly infestation increases in the summer months. They are a public health threat bringing harmful bacteria such as E. coli and salmonella to food, food preparation areas, storage and cooking surfaces.
With warmer temperatures, the decomposition rate of the food sources flies enjoy increases. From fresh produce to garbage, compost and animal feces, the quicker it spoils and breaks down, the more flies love it.
Food processing and food service facility managers facing fly infestations (say that three times fast) need to place their efforts in two key areas:
- Employ good sanitation practices
- Identify the source of the infestation and breeding locations
Sprague’s Fly Management Checklist
-
Proper Identification – Gain the upper hand by correctly identifying the fly species infesting your facility. Correct identification allows you to determine the cause of the infestation and pick a control option. An incorrect identification can lead you on a wild goose chase, wasting valuable time and resources.
-
Eliminate the Source – What is attracting the flies to your facility in the first place? Is it a sanitation issue, or is there a structural flaw (i.e. torn screens, negative air flow, faulty air doors, etc.)? Remove the source of interest and you will likely remove the flies.
-
Sanitation is King – Healthy sanitation practices in and around your facility are critical for keeping flies from gaining a foothold. When you consider that a single overflowing garbage can that is not emptied can be a breeding ground for up to 30,000 flies, you’ll think twice about waiting to take out the trash. Use tight-fitting closures for trash and recycling receptacles. Try to empty, clean, and dry these receptacles on a regular basis. Additionally, keep food preparation, storage and serving areas clean of grease spills, crumbs and other food particles.
-
Remove the Threat – Once you have identified the type of fly and source of infestation, it is time to get rid of them. Interior light traps and sticky boards will prevent flies from flying around inside your buildings. For further protection from these unwanted visitors, check air intake vents for proper screening and use air curtains above your doors.
