Keeping flies away from your food while enjoying the outdoors can be a challenge. At flyermedia.net, we understand the importance of creating a pleasant outdoor dining experience without unwanted guests. We offer tips and tricks to help you keep flies away and enjoy your meal. Explore fly control and other deterrents to maintain a pest-free environment.

1. What Are the Best Ways to Keep Flies Away From Food Outside?

The best ways to keep flies away from food outside involve a combination of preventative measures and active deterrents. Preventing flies from being attracted to your outdoor dining area is key, followed by fly deterrents.

Cleanliness is Key: Always keep your outdoor dining area clean. Wipe up spills immediately and clear away any food scraps. Flies are attracted to sugary substances and decaying matter, so removing these temptations will significantly reduce their presence.
Cover Food: Use food covers, such as mesh domes or plastic wraps, to protect your dishes. This physical barrier prevents flies from landing on your food.
Natural Repellents: Several natural substances repel flies. Planting herbs like basil, mint, lavender, and rosemary around your dining area can help. According to research from Iowa State University Extension and Outreach, these herbs contain volatile oils that act as natural insect repellents. You can also use essential oils like citronella, peppermint, and eucalyptus in diffusers or as sprays.
Fly Traps: Consider using fly traps, either store-bought or homemade. A simple trap can be made by filling a jar with apple cider vinegar and a drop of dish soap. Cover the jar with plastic wrap and poke small holes in it. Flies will be attracted to the vinegar, enter the trap, and be unable to escape.
Fans: Strategically placed fans can create a breeze that flies dislike. Direct the airflow across your dining area to keep these pests away.
Electronic Fly Swatters: Handheld electronic fly swatters are effective for zapping individual flies. They are safe to use around food and provide instant results.

2. What Natural Repellents Work Best to Keep Flies Away From Food?

Several natural repellents are effective in keeping flies away from food, using organic materials and items you have around the house. These options are not only environmentally friendly but also safe for use around children and pets.

Herbs: Planting or using herbs like basil, mint, lavender, and rosemary can deter flies. These herbs emit natural oils that flies find unpleasant. Place potted herbs on your dining table or in nearby gardens to create a natural barrier.
Essential Oils: Essential oils such as citronella, peppermint, eucalyptus, and lavender can be used in diffusers or mixed with water and sprayed around the dining area. According to a study published in the Journal of Economic Entomology, citronella oil is highly effective in repelling various types of flies.
Citrus and Cloves: Place cloves in halved lemons or oranges and set them around your table. The combination of citrus and cloves is a natural fly repellent. This method is not only effective but also adds a pleasant aroma to your outdoor space.
Apple Cider Vinegar Traps: These traps are easy to make and highly effective. Fill a jar with apple cider vinegar and add a drop of dish soap. Cover the jar with plastic wrap and poke small holes in it. The vinegar attracts flies, and the soap breaks the surface tension, causing them to drown.
Penny and Water Trick: Fill a clear glass or bag with water and drop 4 to 5 old pennies inside. Hang these near your dining area. The theory is that flies are deterred by the reflection and the presence of “larger” objects (the pennies).

3. How Effective is Canned Heat (Sterno) for Keeping Flies Away?

Canned heat, often known as Sterno, can be a surprisingly effective method for keeping flies away from your outdoor dining area. The flies are instantly deterred once you light the Sterno gel. They’ll stay away as long as the gel keeps burning, which is several hours. Here’s how it works:

Deterrent Effect: The heat and fumes emitted by the burning Sterno are unpleasant to flies, causing them to avoid the area.
How to Use: Place a can of Sterno on your outdoor table. It’s recommended to remove the label and place it in a decorative, heat-safe vase to enhance the aesthetic and prevent accidental contact with the hot can. Light the Sterno with a stick lighter.
Coverage: For a larger gathering or an 8-person table, place a can of Sterno every few feet to ensure adequate coverage.
Safety: Exercise caution when using Sterno. Keep it away from flammable materials and ensure it is placed in a stable container to prevent tipping.

4. What Role Does Cleanliness Play in Preventing Flies?

Cleanliness is a fundamental aspect of preventing flies from infesting your outdoor spaces. Flies are highly attracted to food residues, spills, and garbage, so maintaining a clean environment is essential for effective fly control.

Prompt Cleanup: Spills and food scraps should be cleaned up immediately. Flies can detect even small amounts of sugary or decaying substances from a distance, making them difficult to manage once they arrive.
Proper Waste Management: Ensure that all trash cans have tight-fitting lids. Regularly empty and clean trash cans to prevent the buildup of food waste and other organic matter that attracts flies.
Surface Cleaning: Regularly wipe down tables and other surfaces with a disinfectant cleaner. This removes any residual food particles and odors that might attract flies.
Pet Waste Removal: If you have pets, promptly clean up any waste in your yard. Pet waste is a significant attractant for flies.
Gutters and Drains: Keep gutters and drains clean and free of debris. These areas can accumulate organic matter that provides a breeding ground for flies.

5. How Do Fly Traps Work, and Which Types Are Most Effective?

Fly traps are designed to attract and capture flies, reducing their presence in a specific area. There are various types of fly traps, each with its own method of attracting and trapping flies.

Sticky Fly Paper: These traps consist of paper coated with a sticky adhesive. Flies are attracted to the paper and become trapped when they land on it. Sticky fly paper is effective but can be unsightly.
Light Traps: These traps use ultraviolet (UV) light to attract flies. Once the flies are close to the light, they are either electrocuted or trapped on a sticky surface. Light traps are commonly used indoors but can also be effective in covered outdoor areas.
Bait Traps: Bait traps use a sweet or decaying substance to attract flies. The flies enter the trap and are unable to escape, eventually drowning in the bait. Homemade bait traps using apple cider vinegar and dish soap are a popular and effective option.
Water Traps: Fill a clear glass with water and drop 4 to 5 old pennies inside. It seems really strange, but it works! Turns out that adult flies are afraid of bugs bigger than them and will be turned away by this.
Fan Traps: Their quiet operation and wide coverage make them an ideal solution for maintaining a comfortable dining atmosphere.
According to the University of California, Davis, bait traps and sticky traps are among the most effective options for controlling fly populations.

6. Are There Plants That Naturally Repel Flies?

Yes, several plants naturally repel flies due to the essential oils they contain. Incorporating these plants into your garden or outdoor dining area can help keep flies at bay.

Basil: Basil is a popular herb that repels flies and mosquitoes. It can be grown in pots or directly in the ground.
Mint: Mint, particularly peppermint, is effective in repelling flies. It is best grown in containers to prevent it from spreading aggressively.

14. How to Make a Homemade Fly Trap?

Creating a homemade fly trap is a simple and effective way to control fly populations in your outdoor spaces. Here’s a guide to making a popular and effective fly trap:

Materials:

Plastic bottle (2-liter or similar size)
Sharp knife or scissors
Sweet bait (apple cider vinegar, sugar water, or overripe fruit)
Dish soap
Water

Instructions:

Cut the Bottle:
- Use a sharp knife or scissors to cut the top off the plastic bottle, about 2-3 inches below the neck.
Invert the Top:
- Invert the top section of the bottle (the part you just cut off) and place it inside the bottom section, creating a funnel.
Secure the Funnel:
- You can secure the funnel in place using tape or staples, but often the fit is snug enough that it stays in place on its own.

- Add a few drops of dish soap to the bait. The soap helps to break the surface tension of the liquid, making it easier for the flies to drown.
Set Up the Trap:
- Place the trap in an area where flies are prevalent.
Monitor and Clean:
- Check the trap regularly and empty it when it becomes full of flies.
- Clean the trap and replenish the bait as needed.

15. What are Some Additional Tips to Keep Flies Away from Outdoor Events?

Hosting an outdoor event requires careful planning to ensure your guests are comfortable and not bothered by flies. Here are some additional tips to help keep flies away:

Pre-Event Preparation:
- Clean the Area: Thoroughly clean the area a day or two before the event. Remove any trash, debris, or potential food sources that could attract flies.
During the Event:
- Cover Food: Keep food covered as much as possible. Use serving dishes with lids or covers, and provide guests with small plates to avoid leaving food exposed.
- Designated Eating Area: Set up a designated eating area away from other activities. This helps to contain food scraps and makes it easier to manage cleanliness.
