Understanding Fly Behavior

Flies are more than just a pest – they’re motivated scavengers with a keen sense of smell, which is pretty impressive. Outdoor restaurants create a great setting for them. They offer tasty smells and easy access to food scraps. The combination of warm weather, open-air seating, and a steady stream of diners creates an ideal setting for these pests to thrive.
Why Are Flies Attracted to Outdoor Dining Areas?
Flies are drawn to:
- Food scents – Strong aromas from grilled meats, sugary drinks, and fresh produce attract flies from long distances.
- Trash and food waste – Overflowing bins, leftover crumbs, and uncleaned tables create a feeding ground.
- Moisture and spills – Sticky soda spills and condensation from drinks provide hydration.
Attractant | Why Flies Love It |
Food aromas | Signals an easy food source |
Garbage & waste | Perfect breeding environment |
Standing water | Essential for fly survival |
Understanding what brings flies to the table is the first step in keeping them away. Restaurants use this knowledge to create good fly control strategies. This helps keep the dining experience pleasant for guests.
10 Creative Ideas On How Outdoor Restaurants Keep Flies Away
1. Thorough Restaurant Cleaning
Thorough restaurant cleaning is the best way to keep flies away from outdoor restaurants. This includes sweeping and mopping floors, wiping down surfaces, and emptying garbage cans.
Also, restaurants should cover food as much as possible. They should avoid leaving uncovered food out for long periods.
While thorough cleaning will not guarantee that flies will never be a problem, it is the best defense against them.

2. Putting Up High-powered Electric Fans
Putting up high-powered electric fans is the most popular way to keep flies away from outdoor restaurants. The fans create an invisible barrier that flies cannot penetrate.
They also make it difficult for flies to land on surfaces and are less likely to lay their eggs in food constantly being blown around.
3. Use Papaya Leaves
Many outdoor restaurants use papaya leaves to keep flies away. Papaya leaves have a natural enzyme called papain. This enzyme breaks down the protein in the fly’s saliva. As a result, the flies can’t feed.
In addition, the scent of the papaya leaf deters flies from landing on it in the first place. Place a few papaya leaves around your outdoor dining area to use this method.
4. Set Up Scent Diffusers & Candles
Most outdoor restaurants have scent diffusers and candles that emit citrus scents. These smells repel flies. They also often have fans set up to create a breeze. This increases the difficulty for flies to land and remain stationary.
Next time you eat outside, pause to appreciate the effort to keep flies away.
5. Practice Garbage Control
To keep flies away, good garbage control is the best method. Many products claim to repel flies, but they aren’t as effective. Flies are drawn to food waste. So, it’s crucial to cover trash bins and clean spills right away.

Ultrasonic waves can travel through walls, so the devices do not have to be directly in sight of the pests to be effective.
Ultrasonic pest repellers are usually safe for people and pets. However, they can disrupt outdoor meals. For this reason, many restaurants only use them when there are no guests.
