Simply fill a plastic bag with water and hang it near where you will be eating. The movement of the water and the shadows it casts makes the flies nervous and they will stay away from the area.
According to a post on Design Milk, "It's a traditional way to scare flies away and is used in most of the food markets in urban Mexico. Light is refracted by the water, the colours and movements of the bag are amplified and the fly is confused and flies away."
If hanging a bag of water in your garden is unappealing, José de la O, a Mexican-born designer now living and working in the Netherlands, created a beautiful solution in the form of his Anti-Fly Sphere. The blown glass droplet shape produces the same effect as the plastic bag, but also serves as an attractive addition to a yard or dining area.
