Flies are not only a nuisance but can also pose health risks by contaminating food and surfaces. Various home remedies claim to repel these pests, one of which involves using a glass of water. However, the effectiveness of such methods is questionable. This article explores the validity of the glass of water trick and offers proven strategies to keep flies at bay.

The glass of water trick suggests that placing a glass filled with water and, in some variations, adding items like fresh coriander or pennies, can deter flies.
