Ways to Keep Flies Out of Your Restaurant This Summer
Flies aren’t just annoying — they’re a food safety risk. Prevention systems matter more than reaction.
When temperatures rise, fly problems increase. In restaurants, even one visible fly in the dining room can damage guest perception. Multiple flies can create health code risk.
The cleanest restaurants don’t just clean — they eliminate the conditions that attract pests in the first place.
1. Control Entry Points First
- Install proper door sweeps and weather stripping
- Repair torn screens immediately
- Use air curtains above high-traffic doors
- Minimize open delivery door time
Flies cannot infest what they cannot access.
2. Dumpster Placement and Maintenance
- Keep dumpsters as far from entrances as possible
- Ensure lids fully close
- Increase waste pickup frequency in peak heat
- Pressure wash surrounding areas regularly
3. Interior Sanitation: Focus on Moisture
- Clean floor drains nightly
- Eliminate standing water
- Wipe syrup stations thoroughly
- Empty indoor trash frequently
- Deep-clean under prep tables
Drains are one of the most overlooked fruit fly breeding sites.
4. The Apple Cider Vinegar + Dish Soap Trap
If fruit flies are already present, this low-cost method can dramatically reduce numbers while you address the root cause.
How It Works
- Apple cider vinegar attracts fruit flies
- Dish soap breaks surface tension
- Flies sink instead of landing and escaping
How to Set It Up
- Mix equal parts apple cider vinegar and water
- Add 2–3 drops of dish soap
- Place near drains, soda stations, or bar areas
The trap reduces the symptom. Sanitation removes the source.
5. What About the “Water Bag With Coins” Trick?
Some operators hang clear plastic bags filled with water and coins near entrances to deter flies. The theory suggests that light refraction confuses fly vision.
While some report success, results vary depending on lighting conditions. It should be considered supplemental, not primary, control.
6. Understand Lighting and Attraction
Flies are strongly attracted to UV light and reflective surfaces.
- Avoid placing UV traps near entrances
- Use warm-toned exterior lighting
- Keep reflective surfaces clean near entry points

Final Thought
Fly problems rarely begin in the dining room. They begin in systems.
Summer doesn’t cause infestations — it exposes weak sanitation routines.
Prevention is always cheaper than emergency response.
