1. What is the “Pennies in Water” Fly Repellent Method?
The “pennies in water” fly repellent method involves placing a few pennies in a clear plastic bag, filling the bag about halfway with water, sealing it, and then hanging it in an area where flies are unwanted. This method leverages the flies’ visual perception, disrupting their ability to navigate effectively. It is considered an environmentally friendly alternative to chemical insecticides, suitable for use in homes, barns, and outdoor settings, aiming to reduce fly populations by exploiting their aversion to reflected light.
How Does it Work?
The theory behind why pennies in water keep flies away centers on how flies perceive light and reflections. Here’s a breakdown:
- Visual Disruption: Flies have compound eyes, which are highly sensitive to movement and light. The bag of water, especially when combined with the reflective surface of the pennies, creates a prism effect that distorts and refracts light.
- Confusion: The scattered light and reflections may confuse flies, making it difficult for them to orient themselves and navigate. This disorientation can deter them from entering or remaining in the vicinity of the bag.
- Mimicking Water Surface: Some theories suggest that the moving reflections on the water’s surface mimic the appearance of water bodies, which flies generally avoid due to the risk of drowning.
Is There Scientific Evidence?
While anecdotal evidence and testimonials abound, robust scientific studies specifically validating the “pennies in water” method are lacking. Most of the support is based on observational results reported by individuals who have tried the technique. Further research is needed to determine the efficacy and underlying mechanisms of this method.
1.1 How Did This Method Originate?
The “pennies in water” fly repellent method is often attributed to old folk wisdom, particularly among the Amish and other rural communities. These communities have historically relied on natural and non-chemical methods for pest control. Over time, the practice has been adopted by others looking for eco-friendly ways to manage fly populations.
1.2 What Are the Benefits of Using This Method?
Using the “pennies in water” method offers several benefits:
- Eco-Friendly: It’s a non-toxic alternative to chemical insecticides, making it safe for use around children, pets, and food.
- Cost-Effective: The materials required (a plastic bag, water, and a few pennies) are inexpensive and readily available.
- Simple: The setup is easy and requires minimal effort.
- Aesthetic: While not the most stylish decoration, it can be less obtrusive than some commercial fly traps.
- Accessibility: The method can be implemented almost anywhere, making it suitable for a variety of settings, from homes to stables.

2. Step-by-Step Guide: How to Set Up a “Pennies in Water” Fly Repellent
To effectively set up a “pennies in water” fly repellent, follow these simple steps:
- Gather Supplies: You will need a clear plastic zip-top bag (sandwich or quart size), 4-6 shiny pennies, and clean water.
- Prepare the Bag: Open the plastic bag and place the pennies inside.
- Add Water: Fill the bag approximately halfway with water. Ensure there is enough water to allow the pennies to move freely.
- Seal the Bag: Securely seal the bag, removing as much air as possible to prevent it from bursting.
- Check for Leaks: Turn the bag upside down to check for any leaks. If leaks are present, use a new bag.
- Hang the Bag: Use string, twine, or a hook to hang the bag in the desired location. Popular spots include doorways, windows, patios, and barns.
2.1 Tips for Enhancing Effectiveness
To maximize the effectiveness of the “pennies in water” fly repellent:
- Use Shiny Pennies: Clean the pennies to ensure they are as shiny as possible, enhancing their reflective properties.
- Optimal Placement: Position the bags in areas with good lighting to maximize light refraction and reflection.
- Regular Cleaning: Replace the water every few weeks to keep it clear and free of debris, maintaining optimal visual disruption.
- Multiple Bags: Use multiple bags in larger areas or locations with heavy fly traffic.
2.2 Common Mistakes to Avoid
Avoid these common mistakes when setting up your fly repellent:
- Using Dirty or Tarnished Pennies: Dull pennies will not reflect light as effectively.
- Overfilling the Bag: Too much water can reduce the reflective effect and increase the risk of the bag bursting.
- Placing in Shady Areas: Insufficient light reduces the effectiveness of the method.
- Ignoring Leaks: A leaky bag will quickly lose water and effectiveness.
- Not Replacing Water: Over time, the water can become cloudy, reducing its ability to refract light.
3. Understanding Why This Method May Work: The Science Behind It
While the “pennies in water” method is widely used, the exact scientific explanation for its effectiveness remains debated. Here are the most common theories:
3.1 Light Refraction and Visual Disruption
- Theory: The combination of water and shiny pennies creates a prism effect, scattering light in various directions. This confuses flies, which rely on consistent light patterns for navigation.
- Explanation: Flies have compound eyes that are highly sensitive to movement and light. The distorted light patterns produced by the bag disrupt their ability to orient themselves, deterring them from entering the area.
3.2 Fly Vision and Compound Eyes
- Theory: The reflective properties of the water and pennies create a visual field that is unappealing or even frightening to flies.
- Explanation: Flies perceive the world differently than humans. Their compound eyes are made up of thousands of individual lenses, each capturing a small part of the overall image. The scattered light and reflections may create a confusing mosaic that deters them.
3.3 Psychological Deterrent
- Theory: The mere presence of the bag may act as a psychological deterrent, signaling to flies that the area is not safe or suitable for landing.
- Explanation: Flies are known to avoid certain environments based on visual cues. The unusual appearance of the bag may trigger an instinctive avoidance behavior.
3.4 University Research on Insect Vision (Embry-Riddle Aeronautical University)
According to research from Embry-Riddle Aeronautical University, in July 2023, understanding insect vision can lead to innovative pest control methods. Although no direct validation of the “pennies in water” method yet exists, the principles of visual disruption are well-supported in entomological studies.
4. Alternative Fly Repellent Methods
If the “pennies in water” method doesn’t provide the desired results, numerous alternative fly repellent methods are available. Here are some popular and effective options:
4.1 Natural Fly Repellents
- Essential Oils: Certain essential oils, such as peppermint, eucalyptus, lavender, and citronella, are known to repel flies. You can diffuse these oils or create a spray by mixing a few drops with water.
- Herbs: Planting herbs like basil, rosemary, and mint around your home can help deter flies. These herbs emit scents that flies find unappealing.
- Vinegar Traps: Fill a jar with apple cider vinegar and add a few drops of dish soap. The sweet scent attracts flies, but the soap prevents them from escaping.
4.2 Commercial Fly Traps
- Sticky Traps: These traps use a sticky surface to capture flies. They are available in various forms, including strips, rolls, and boards.
- Light Traps: These devices use ultraviolet light to attract flies, which are then zapped or trapped.
- Bait Traps: These traps use a bait to lure flies into a container from which they cannot escape.
4.3 DIY Fly Traps
- Plastic Bottle Trap: Cut the top off a plastic bottle, invert it, and place it inside the bottom half, creating a funnel. Fill the bottom with a sweet liquid, such as sugar water or fruit juice.
- Wine Trap: Leave a small amount of wine in the bottom of a bottle. Flies will be attracted to the scent and become trapped inside.
4.4 Preventative Measures
- Maintain Cleanliness: Regularly clean your home, especially the kitchen, to remove food sources that attract flies.
- Proper Waste Disposal: Ensure that garbage cans are tightly sealed and emptied frequently.
- Eliminate Standing Water: Flies breed in standing water, so eliminate sources of stagnant water around your property.
- Screen Doors and Windows: Install screens on doors and windows to prevent flies from entering your home.
