The Curious Case of the Penny Fly Deterrent: A Chef’s Unexpected Discovery

I’ll never forget the summer we hosted my parents for an extended stay. As much as I adore them, their visit coincided with an unusually aggressive fly season. It seemed no matter how diligently we cleaned, those buzzing bandits would find their way in, especially around the back door leading to the patio – prime real estate for summertime gatherings. I tried everything: fly swatters, sticky traps, even those electric zappers. Then, a neighbor shared the strangest tip, something she’d learned from her grandmother: a bag of water, pennies, and a bit of ingenuity could keep flies at bay. Skeptical, but desperate, I gave it a try. The results? Let’s just say I was eating humble pie, alongside a fly-free burger, that very weekend.

Recipe Overview

• Prep Time: 5 minutes
• Cook Time: 0 minutes
• Total Time: 5 minutes
• Yields: 1 Bag
• Serves: Variable, area dependent
• Dietary Type: Non-Edible, Pest Deterrent

Ingredients

• 6 pennies
• 1 ziploc bag (sandwich or quart size)
• 1-2 cups water, enough to fill the bag about halfway
• String or fishing line for hanging

Equipment Needed

• Ziploc bag
• String or fishing line
• Scissors or hole punch (optional)

Instructions

1. Begin by taking your ziploc bag and filling it approximately halfway with water. The amount of water isn’t critical, but you want enough to allow the pennies to be clearly visible and to give the bag some weight.

2. Next, add the pennies. Distribute them around the bag; placing three in each of the bottom corners can help with stability and visual effect.

3. Carefully close the ziploc bag, ensuring it’s sealed tightly to prevent any leaks.

4. Create a hole for hanging. You can either use scissors to carefully puncture a hole in the center of the bag, just above the ziplock closure, or use a hole punch for a cleaner look.

5. Thread the string or fishing line through the hole. Tie a secure knot to create a loop for hanging.

6. Hang the bag in the desired location. It may take up to a day to notice the difference, but the flies should start to decrease noticeably. Places to hang include near doors, windows, garbage cans, patios, or any area where flies are a nuisance.

Expert Tips & Tricks

• The Penny Mystery: While the exact science is debated, the prevailing theory is that the reflection of light off the pennies and the movement of the water disorient the flies, deterring them from the area.
• Sunlight is Key: Ensure the bag is hung in a location where it will receive ample sunlight for the reflective properties to work effectively.
• Bag Quality Matters: Use a good quality ziploc bag to prevent leaks. Double-bagging can provide extra protection.
• Water Clarity: Keep the water clean. If it becomes murky or cloudy, replace it for optimal effectiveness.
• Placement Strategy: Experiment with different locations to find the most effective placement for your specific fly problem. Areas with strong drafts or consistent movement can enhance the deterrent effect.
• Copper’s Potential Role: Some believe that the copper in the pennies contributes to the deterrent effect. While not scientifically proven, using newer, shinier pennies might enhance the visual reflection.

Serving & Storage Suggestions

This isn’t something you serve, but rather something that serves you! The fly deterrent bag is best used immediately after assembly. Store it by hanging it in its designated location. If you need to temporarily remove it (e.g., during a storm), simply take it down and re-hang when conditions improve. The solution is most effective when the water is clean and clear. Replace the water as needed (every few weeks or when it becomes cloudy) to maintain its effectiveness. The bag itself should last for an extended period, but inspect it regularly for any signs of wear or leakage. If the bag becomes damaged, replace it with a new one.

Nutritional Information

Since this isn’t an edible recipe, nutritional information isn’t applicable. However, here’s a table representing the “nutritional” value of this fly deterrent in terms of its environmental impact (hypothetically):

Category	Amount	Notes
Fly Population Reduction	Significant	Varies depending on environment
Buzzing Noise Reduction	Noticeable	Contributes to a more peaceful setting
Chemical Usage	0%	Environmentally friendly alternative
Annoyance Factor	Reduced	Promotes relaxation and enjoyment

Variations & Substitutions

• Shiny vs. Dull Pennies: Some prefer newer, shinier pennies for maximum reflection, while others believe older, more tarnished pennies work just as well. Experiment and see what works best in your environment.
• Additional Reflective Elements: Add small pieces of glitter or shiny confetti to the water for enhanced reflection. Be mindful of environmental impact when considering this option.
• Essential Oils (with Caution): A few drops of fly-repelling essential oils, such as eucalyptus or peppermint, can be added to the water. However, be cautious when using essential oils around children and pets, and research appropriate dilution ratios.
• Clear Marbles or Glass Beads: Instead of pennies, use clear marbles or glass beads for a different aesthetic effect. The reflective properties should still provide a deterrent.
• Different Bag Shapes: While a standard ziploc bag is convenient, you could use other clear plastic containers, such as small bottles or decorative bags. Ensure the container is securely sealed and can be easily hung.

FAQs (Frequently Asked Questions)

Q: Does this really work, or is it just an old wives’ tale?
A: While scientific evidence is limited, many people swear by this method. The prevailing theory suggests that the reflection of light off the pennies and water disorients the flies, making them avoid the area.

Q: How long does the deterrent effect last?
A: The effectiveness can vary depending on environmental conditions. Regularly check the water clarity and replace it as needed (every few weeks or when it becomes cloudy) to maintain optimal performance.

Q: Can I use this indoors?
A: Yes, you can use the fly deterrent bag indoors, particularly near windows, doors, or areas where flies tend to congregate.

Q: Are there any risks associated with hanging this bag?
A: The primary risk is the potential for the bag to leak if it’s not properly sealed or if it’s punctured. Ensure the bag is securely closed and inspect it regularly for any signs of damage.

Q: Why pennies? Can I use other coins?
A: Pennies are traditionally used, likely due to their copper content and reflective properties. While other coins might offer some reflective effect, pennies are the most commonly recommended.
