Repel Flies Naturally: The Water Bag and Coins Method

A traditional trick to repel flies, using a bag of water and coins, remains popular despite the lack of scientific confirmation.

The technique is based on the idea that light reflections from the water and coins disorient flies, preventing them from approaching.

Although there is no scientific evidence, many users report a reduction in flies when using this method. Its simplicity, low cost, and absence of chemicals make it an attractive option.

The method is widespread in countries such as Spain, Portugal, and Latin America.
