Debunking the Pennies Water Fly Myth: What Really Works to Repel Flies

Flies become a major nuisance as the temperature rises. People often try home remedies like hanging water bags with pennies inside. This DIY method, known in viral posts and backyard conversations, has sparked the popular Pennies Water Fly Myth.

Many believe that the reflections from sunlight, water, and pennies confuse a fly’s eyesight and make them fly away. But does science support this trick? Let’s explore expert insight and reliable fly-repelling solutions that actually work.

Does the Pennies-in-Water Trick Repel Flies?

Unfortunately, the Pennies Water Fly Myth doesn’t hold up under scientific scrutiny, according to entomologist Emma Grace Crumbley. While the visual explanation seems creative, there is no scientific backing to support its effectiveness.

“There is not enough evidence to suggest that this is an effective preventative method for fly control,” Crumbley confirms. In fact, the water in the bag can actually attract more flies rather than repel them.

“Condensation on the bag can attract flies. Leaks from the bag create new moisture spots for flies to drink from,” she adds.

So, while the trick may look cool hanging by the patio, don’t count on it to solve your fly problem.

Pennies Water Fly Myth vs. Proven Fly-Repelling Methods

Instead of relying on myths, experts recommend practical, science-backed solutions to control fly infestations. These methods don’t require coins or plastic bags and offer real results.

1. Use Citronella

Citronella works well in plant or candle form. Its strong lemon-like scent deters flies and other insects from approaching your space. Place citronella in gardens, kitchens, or outdoor sitting areas for the best effect.

2. Keep Trash and Waste Clean

Flies love garbage and rotting food. Crumbley advises homeowners to reduce organic scents by sealing bins and picking up pet waste regularly.

Clean compost piles and ensure lids stay tightly closed to limit breeding grounds for flies.

3. Spray DEET-Based Repellent

EPA-registered DEET repellents offer strong protection outdoors. DEET blocks a fly’s ability to detect humans, making it effective for camping or yard work.

Apply it during peak fly activity times for maximum protection.

4. Try Peppermint Oil

Peppermint is a natural insect repellent. Grow mint in your garden or create a peppermint spray using water and essential oil.

Spray this around doorways, windows, and areas where flies gather. Reapply often to maintain its scent.

Extra Tips to Keep Flies Away for Good

Besides scent-based deterrents, taking physical measures around your home helps reduce fly activity even more. Try combining these with repellents for better results.

Remove Moisture Quickly

Flies thrive in moist environments. Empty any standing water, dump kiddie pools, and dry out shaded areas after watering plants.

Running fountains regularly keeps water moving and discourages egg-laying.

Control Food Sources

Don’t let food sit out. Cover all leftovers and clean crumbs from surfaces. Secure trash bins and food storage containers.

Flies also feed on decaying matter, so dispose of old produce and animal waste quickly.

Install Protective Screens

Screens on windows and doors prevent flies from entering your home. You can also screen-in patios for outdoor relaxation without pests.

Double-check screens for tears or gaps and patch them as needed.

Run a Fan Indoors and Outdoors

Flies dislike air circulation. Fans help maintain airflow and make it harder for flies to land or linger in an area.

Place fans near tables or kitchen areas for additional fly control during meals.
